Growth and PotentialHere at Virgo Communications we take very seri-ously our role as a provider of information and a facilitator of trade and business opportunities. Even though the economic climate has been somewhat difficult over the last year, we’re extremely optimistic about the potential for growth for those in the gear and power transmission industries.

It is widely reported that India is one of world’s leading growth generators for industrial and infrastructure develop-ment, and continues to show generally constant growth in the manufacturing sector. Technological growth, regulatory reform and skilled workers, along with rapid globalization and sharp competition among nations, have been the catalysts driving commerce in India.

A study by McKinsey & Company estimates that rising domestic demand in India, along with multinationals’ desire to enlarge their footprint here, could boost the country’s manufac-turing sector six-fold by 2025 — to U.S. $1trillion — while cre-ating up to 90 million domestic jobs. Also, owing to the avail-ability of a massive workforce, a robust supply base, and access to natural resources needed in production, India is definitely poised to become a viable manufacturing alternative to China. Not only that — if the resources are efficiently utilised, India might even dominate some skill-intensive manufacturing sec-tors in the years to come.

With that optimism in mind, we are busy preparing the next edition of the IPTEX trade show, which is emerging as one of the most promising platforms for those in the gear and power transmission equipment industry to network with peers and potential buyers and to market their products, services and capabilities to a diverse and motivated audience. IPTEX exists to provide an open forum to the members of this industry so they may share their knowledge, expertise and ideas with oth-ers in the industry, and to join in discussions on, for example, “shop talk,” supply chain, or international standards.

Having recently returned from AGMA’s Gear Expo in Indianapolis, we have seen the power of a highly targeted trade show and the value of gathering an industry’s motivated profes-sionals together at one venue. You can see our post-show cover-age of Gear Expo on page 20).

With your participation, IPTEX has the potential to be just as powerful a force in the Indian marketplace as Gear Expo is in North America. IPTEX continues to be India’s go-to venue for showcasing the country’s manufacturing sector and its latest advances in gear and power transmission component manufac-turing. In fact, the AGMA itself has been a generous supporter of IPTEX, and has always encouraged its own members to look at participation here as an opportunity to expand their business.

Virgo Communications strives to make IPTEX the perfect matchmaker between buyer, seller, and a wide array of gear and power transmission components. This show’s third edi-tion will attract more than 100 exhibitors and more than 5,000 visitors from varied user segments; indeed, IPTEX has won the appreciation and recognition of exhibitors and attendees from the Indian and global manufacturing industry. The 2014 show will also be co-located with Grindex — an exhibition on grind-

ing and surface finishing — providing even greater value and opportunity to the attendees.

The Knowledge Forum will again be a part of IPTEX, pre-senting a panel of distinguished representatives from the gear and power transmission industries. In the 2012 forum, Mr. Ashok Sexena, former managing director of HAL, spoke of the opportunities for gear companies in the aerospace sector. In 2014 the forum will address opportunities for the gear industry in the defense, power and automotive sectors.

We know that travelling to trade shows isn’t always easy. It’s expensive, both in the direct costs of travelling and in the time it takes away from your other duties. But through the expansion of the show and our continued focus on valuable educational opportunities, we’ve all we can to ensure that your time spent at IPTEX will be worthwhile.

On top of all the work we do for IPTEX, we work hard—along with our partners at Randall Publications LLC—to give you the same type of value in the pages of this magazine. We are proud that Gear Technology India has become yet another chan-nel for consistent communication among buyers and sellers and the industry at large.

Just like IPTEX provides a valuable opportunity to identi-fy, and meet with new suppliers, so too, does Gear Technology India. In this issue, we’re pleased to present the second edition of our Buyers Guide, where you’ll find comprehensive list-ings of suppliers of machinery, tooling and services for gear manufacturing (beginning on page 26); as well as a directory of suppliers of mechanical power transmission components (beginning on page 34). We hope you will take advantage of the Buyers Guide as a way to identify new potential suppliers of the products and services you need.

In our next issue, we’ll bring you in-depth coverage of IPTEX, including a complete guide to the show and thorough descriptions of the offerings of the exhibitors. We’re confi-dent that this will help you plan your visit to the show. With the next issue, we’ll also be celebrating our second anniversary and beginning our third year of publication. I’d like to take this opportunity to thank all contributors, advertisers and subscrib-ers for their help in bringing this terrific magazine to the mar-ketplace.

We look forward to seeing you all again at IPTEX 2014.

P.S. The 3rd International Power Transmission Expo (IPTEX 2014) takes place February 27-March 1 at the Bombay Exhibition Centre in Mumbai. For more information, visit www.iptexpo.com.

MHITOUTS GEAR SHAPING TECHNOLOGY

Mitsubishi Heavy Industries, Ltd. (MHI) has completed the development of a new gear shaping machine, the ST40A, capable of cutting a broad array of gears, including helical and cluster gears, with one system. The ST40A’s significantly expanded range of cutting applications derives from the first application in Japan of NC programming technology to the relieving motion that prevents interfer-ence between the cutter and the work-piece. The machine made its internation-al debut in the United States with a live demonstration of its capabilities at Gear Expo 2013, in Indianapolis. The ST40A is a totally upgraded version of the ST40, a helical gear shaping machine requiring no helical guide for each workpiece. The ST40A has extended the ST40’s cutting flexibility even further by incorporating Japan’s first NC-programmable relieving mechanism and making all seven of the machine’s axes fully NC-programmable. This new capability enables the ST40A to accommodate various high-preci-sion cutting applications such as crown-ing and tapering. In addition, stroke speed

has been increased by 20 percent, from the earlier 500 strokes per minute to 600, enabling high-speed cutting with a focus on productivity. Stroke speed when machining at lower speeds meanwhile has been reduced by 50 percent, from 60 strokes per minute to 30, enabling secure cutting of hard workpieces. The new machine is also capable of taper-ing up to 0.3 degrees without use of a tilt table. In these ways, the ST40A has been designed to fully address diverse user needs, including demand for a broad-er range of optional devices and func-tions, and enhanced operability, safety and energy savings. The company intends to market the ST40A for a wide spec-trum of gear cutting applications for vari-ous products including automobiles, con-struction machinery and aircraft.For more information:MHI-IPTPhone: +(91) 11 [email protected]

KISSsoftOFFERS LATEST SOFTWARE UPGRADES

KISSsoft covers a broad range of appli-cations in a single software package. The latest release of KISSsoft (Version 03/2013) incorporates the newest advances in contact analysis for both cylindrical gearing and planetary geared systems as well as fine sizing for worm wheels and crossed helical gears.

Fine Sizing for Worm Wheels and Crossed Helical GearsFor the calculation of worm wheels and crossed helical gears, fine sizing mod-ules are now available (module ZD5 and ZE6). The KISSsoft fine sizing is applied to gear optimizations of all kinds — from static strength to noise optimi-zation. Thereby, the macro geometry is varied in desired areas and the opti-mal solution according to various crite-ria is selected from the calculated vari-ants. Plastic helical gears can be directly calculated according to the new draft of VDI 2736. After the cylindrical and bevel gears, these fine sizing modules complete the sizing process for all teeth.

Configurable Manufacturing Drawings for Cylindrical GearsFor all cylindrical gears, custom configu-rable manufacturing drawings are now available in KISSsoft (module ZPK). The gear data and a range of different graph-ics−such as flank modifications, etc.−can now be displayed in one graphic, output to screen or paper, and sent to the gear manufacturer. At the same time, graphic position and scale can be set by the user on his own. Now gear data can be eas-ily arranged and placed on the graphic. The settings are saved in a separate file and thereby adopted for all gears. This approach favors also the definition of


SchaefflerOFFERS TRANSPARENT MACHINE TOOL TECHNOLOGY

Schaeffler showcased its machine tool technology during EMO Hannover 2013. With an emphasis on its Transparent Machine Tool, the com-pany focused on meeting custom-er demands both economically and technically. “Optimizing the over-all system is always front and cen-ter in our minds,” explains Martin Schreiber, the new manager of Schaeffler’s Production Machinery Business Unit. “Along with bearing supports and guidance systems, this opens up for Schaeffler not only the entire direct-drive technology, but also the integration of additional functions into rotary and linear bear-ing systems, such as damping and measuring systems.”

Rotary Axes: Absolute Angular Measuring System Integrated into the BearingSchaeffler has developed an angu-lar measuring system integrated into the bearing with an inductive mode of operation that is suited to the demands of direct-driven highly dynamic and precise rotary axes in machine tools. This has result-ed in further developments to the principle of integrating the SRM measuring system into a rotary axis bearing that was already implemented successfully in the YRTM series. The SRM measur-ing system combines high measuring speeds and pre-cision as well as installa-tion space reduction and robustness. It is not sen-sitive to contamination, features a center opening in the rotary axis, and impresses with how little alignment work it requires. Bearings of the new INA series YRTSMA are available in bore-hole diameters ranging from 200 mm to 460 mm. This is the mechanical equivalent to the highly rigid YRTS high-speed bearing series.

Direct-Drive Technology for Turning and Milling OperationsThe rotary high-performance direct drive series RKI of INA Drives & Mechatronics AG & Co. KG (IDAM) offers 30 percent more torque com-pared to convent ional torque motors, according to a Schaeffler press release. Energy efficiency is improved, and the operating costs drop significantly since cooling requirements are lower. For improved performance, it is possible to use smaller motors for the same capacity, thus reducing costs for the converter and motor

Main Spindle: High-Speed Axial Bearings for High Performance and PrecisionThe use of high-speed FAG axial bearings of the BAX series now makes speed parameters possible for

combinations of open axial bearings with cylindrical roller bearings on main spindles that were previously only able to be attained with spin-dle bearings. At the same time, this bearing combination features a sep-

company standards. Those interested can look at the manufacturing drawing examples in a KISSsoft test license by e-mailing [email protected].

Evaluation of Gear Modifications in the Radar ChartAnother highlight in the KISSsoft Release 03/2013 is the extended settings and evaluation options for optimizing modi-fications of cylindrical and planet gears. A new feature is that the face load factor KHβ can now also be calculated. This therefore reveals the direct influence of the tooth trace modification on the safe-ties of the classic tooth root and flank load capacities.

Modifications are evaluated in the radar chart, which also provides a very clear comparison, especially within dif-ferent partial loads.

Contact Analysis for Planetary UnitsThe contact analysis has been greatly extended for planetary gear units (mod-ule ZA30). It is now possible to take into account the exact deflections of the shafts on the sun, the planet, and the internal gear. The planet carrier position is also determined by a shaft calculation, or can alternatively be specified as a displace-ment. The results are finally displayed in the 3-D system, ensuring maximum clar-ity. This provides a powerful analysis tool for the planet system. New dimensioning suggestions are now calculated for mod-ifications, especially for planetary gear units (module ZA5). This ensures that tooth trace modifications can be specified accurately, on the basis of the planet car-rier torsion and sun gear deformation.For more information:KISSsoft AGPhone: +(41) 55 254 20 50www.kisssoft.ag

Sandvik CoromantINTRODUCES COROCUT QD

Sandvik Coromant introduces a brand new parting off concept for deep grooves and long overhangs. For volume bar-fed parts manufactur-ing, producers are continually seek-ing solutions that offer more efficient material usage to control their overall costs and support increased bar feed capacity. Ensuring process security through a predictable and consistent tool life is also important to ensure reproducible parts quality, particular-ly for parting off.

With the introduction of CoroCut QD – a range of solutions cover-ing parting and SL blades, adaptors, shank and Swiss tools and a new gen-eration of inserts for parting off – these aspirations can be met. CoroCut QD builds on the well-proven Q-Cut and CoroCut ranges, and expands the options for these processes with a flexible, simple-to-use and easy-to-select tooling range.

Key design featuresThe focus areas in developing this new concept have been new tool material and a tooling design for greater process stability. The tool attach-ment is achieved via a smart, yet simple, user-friendly clamping mech-anism. The tool tip seat is tilted 20 degrees and incorporates a back stop to withstand high cutting forces. For insert widths 0 .078 in. (2 mm) and

wider, the insert interface has a rail to increase stability.

In developing CoroCut QD, atten-tion has been paid to the development of new and upgraded parting geom-etries. When parting off a component, minimized cutting forces and efficient material removal are important. An insert should be as narrow as pos-sible and have a geometry that makes the chip narrower than the groove to provide a parting off operation with good chip control and surface fin-ish. Within the CoroCut QD concept are inserts with five parting geom-etries and one turning geometry as well as options for “do-it-yourself ” grinding and tailor-made options for a broad range of material types. The PVD insert coating offers better adhe-sion, improved edge-line qualities and better ER tolerance.For more information:Sandvik Coromant U.S.Phone: (800) SANDVIKwww.sandvik.coromant.com/usSandvik Coromant IndiaPhone: +(91) 20-2710-4720www.sandvik.coromant.com

aration of the axial and radial load in the bearing support. Since this means that there are no tilting effects that have to be absorbed, the kinematics are not adversely affected when there is a com-bined load. This makes the bearing sup-port particularly robust. The user profits from a high degree of operating preci-sion as a result of the high rigidity. The load carrying and rotary capacity are both excellent, giving good cutting per-formance and high productivity.

Main Spindle: Friction Optimization by Means of Modern BearingsWith the FAG RS (“Robust and Speedy”) for spindle bearings and TR (“Thermally Robust”) for cylindrical roller bearings, Schaeffler offers a combination of high load carrying capacity and high perfor-mance reserves for increasing speeds. At the same time, the friction-opti-mized inner design makes it possible to reduce the friction loss of the bear-ing support. This is primarily noticeable when the spindle runs for a long time at high speeds. The option to lubricate the bearing support with grease even at high speeds increases the operating safety of the spindle and lowers costs by eliminat-ing the need for compressed air to sup-ply the bearings with lubricant.For more information:Schaeffler IndiaPhone: +(91) 20 3061 4100www.schaeffler.com

Fagor AutomationOFFERS LATEST ENCODER AND CONTROL TECHNOLOGY

Fagor Automation presented a full range of glass-based absolute encoders and steel-tape-based linear encoders of up to 50 m during EMO Hannover 2013. New developments were presented in the whole range reaching a resolution of 10 Nm along with high-resolution abso-lute encoders of up to 27 bits. In addition, the company offered a dedicated area at the fair for steel-tape linear encoders of up to 50 m even with absolute technol-ogy, a record that they expect to break in new projects with their customers. One show highlight was a new steel tape tensioning system that allows removing the reader head at either end, which is claimed to yield considerable cost savings as well as a significant reduction in instal-lation and after-sales service time. This is seen as being particularly evident in large machines in particular. As an inno-vation, the company claims to have been able to combine in a single product the steel-tape linear encoder and its absolute technology with a resolution of 10 Nm.

Furthermore, the manufacturers present-ed the connection of encoders through the Drive-CLiQ interface to Siemens sys-tems so as to offer as wide a selection as possible to the machine tool market.

In addition, the CNC 8060 has been designed by Fagor to provide the machine user with an optimal solution for machin-ing centers and production lathes. User requirements have reportedly been placed in the forefront during develop-ment. According to the Spanish manu-facturer, the HSSA machining system can smooth machining paths using splines and offers not only a suitable part finish

but also a high machining speed, reduced mechanical strain, and top accuracy. Moreover, the high-resolution graphics allow the programming to be checked with micrometer accuracy with the corre-sponding prevention of possible damage to the final part. In low visibility environ-ments, for instance involving coolants or chips, the machining process can be con-trolled while executing the program.For more information:Fagor Automation IndiaPhone: +(91) 8 042 682 [email protected]

LiebherrINTRODUCES LGG 180

Liebherr’s new LGG 180 machine for pro-file and generating grinding combines short grinding times with consistent high large-scale production quality, thanks to a one-table design. The advantage to the one-table solution is higher quality throughout the entire production. Every machined part is manufactured under the same conditions for the highest reproducibility, said Dr.-Ing. Andreas Mehr, grinding and shaping technology development and consultancy at Liebherr-Verzahntechnik GmbH. “A key argument in favor of the one-table solution is the statistical capability and reliability in con-tinuously producing controlled µ-range fin-ish quality,” Mehr emphasizes.

The new grinding head allows for rota-tion speeds up to 10,000 rpm and has spin-dle power of 35 kW. Given this perfor-mance data, the head enables high cutting speeds and high feed rates. The new grind-ing machine can exploit the considerable potential of the innovative abrasive Cubitron II. The machine will enable undulations to be applied specifically to gear wheel flanks for noise optimization purposes for the first time. The ability to produce sub-µ range wav-iness cost-effectively gives designers a whole new range of optimization options.

Production advantagesThe LGG machine delivers fast process-

ing combined with the set-up advantag-es of a one-table solution. In addition, the machines for both 180 mm and 280 mm gears have the same compact external dimensions, facilitating installation within production lines. “Vehicle manufacturers can thus devel-op a complete production line, in which all gearing components for a passenger vehi-cle transmission can be ground: planetary and sun gears, bore-type gears, as well as drive and pinion shafts with lengths up to 500 mm. In order to minimize any thermal impacts, the machine bed is of a thermal-ly stable material. The core of the machine is the newly developed grinding head. Conventional solutions have been chosen here in several areas in order to be prepared for yet higher quality requirements.For more information:Liebherr Verzahntechnik GmbHPhone: +(91) 80 22272781www.francisklein.in

Gleason Corp.INTRODUCES PHOENIX 280G

The new Phoenix 280G Bevel Gear Grinding Machine establishes a new benchmark for bevel gear grinding for gears up to 280 mm in diameter with a design that’s reliable, highly produc-tive and easy to operate and maintain. There are no rails, wires, or pipes in the work chamber to collect swarf, keeping the chamber clean for low preventative maintenance. In addition, the machine offers rapid set-up and all major set-up items can be completed without tools (tool-less), including the grinding wheel, coolant header and workholding. The coolant header has small blocks that can easily be swapped out by hand, while the grinding wheel can be released hydrauli-cally. Some of the other significant fea-tures of the Phoenix 280G include:

Reliability – A well-designed work chamber ensures optimum swarf evacu-ation. The wheel dresser, for example, ‘telescopes’ completely out of the work chamber to reduce the wiring/piping typically found there. The tool-less, quick-change coolant header design fea-tures a laser guidance device that makes part-to-part pipe alignment more effi-cient and repeatable when compared to

manual align-ment.

Productivity – High-speed d i r e c t - d r i v e spindles com-bine with quick-change wheel, arbor and cool-a n t h e a d e r d e s i g n s a n d automatic stock dividing (simultaneously with wheel dressing) to deliver faster floor-to-floor times.

Accuracy – Featuring the extreme rigidity of the Phoenix Monolithic col-umn, cast from advanced polymer com-posite material to achieve very high ther-mal stability and damping characteris-tics.

Easy to operate and maintain – Equipped with powerful Fanuc 30i or Siemens 840D CNC, and Gleason’s user-friendly software empowers even less experienced operators; Phoenix design simplifies installation, integration with robots and gantry-type automation, and maintenance.

Automatic stock divider- The 280G’s Automatic Stock Divider, mounted in close proximity to the workspindle, helps ensure consistently high gear quality. The unit automatically determines the tooth slot position of the pre-finished gear to provide accurate and reliable stock division, helping eliminate opera-tor errors.For more information:Gleason Works IndiaPhone: +(91) [email protected]

BreviniDELIVERS CUSTOM GEARBOXES FOR OFFSHORE OPERATION

In the world of offshore oil and gas, everything is built big, and the Pieter Schelte is no exception. Owned by the Swiss-based Allseas Group, this vessel will surpass the current largest platform installation/decommissioning and pipe laying vessel by 50 percent. Measuring 382 m long and 124 m wide, the vessel is designed for the installation and removal of entire gas/oil rig topsides and their corresponding steel jacket-based plat-forms, as well as being able to lay pipe up to 68 inches in diameter. Once com-plete, the Pieter Schelte will be able to lift entire topsides weighing 48,000 tonnes and steel jackets weighing up to 25,000 tonnes in a single lift. Specialist pipelay-


ing equipment will allow the vessel to operate in ultra-deep water and continue to push the boundaries of what was pre-viously possible.

During pipe laying operations, it is crucial to keep the pipe under tension to maintain the bending and axial stresses within acceptable range. Through con-tinually controlling the tension on the pipeline being laid, integrity of the pipe-line is guaranteed without the necessity of extensive support structures. If poor sea conditions result in an unworkable situation, i.e. the pipeline integrity can-not be guaranteed anymore, then the abandon and recovery (A&R) winches are used to lower the pipeline to the sea-bed in a precautionary abandonment procedure. When the conditions have improved, the pipe is recovered and the pipe laying operation can be continued.

The A&R winch manufacturer required a reliable and very compact design as well as fast production times, and for these reasons Brevini was select-ed to supply the gearboxes. The cus-tom-made gearboxes were based on the Posired 2 High Power series, a combina-tion of the Posired 2 product and the S series planetary reduction. This extreme-ly powerful and efficient gearbox is capa-ble of an output torque of 135 kNm at a speed of 23.1 rpm with an installed power of 520 kW. The custom gearboxes were supplied with a custom-made bell housing and an integrated disc brake as well as temperature sensors for bear-ing and oil temperature. The specifica-tion also called for an offshore coating to be applied to ensure the package could withstand operating in the tough marine environment.

Part of the procurement process required a complete factory acceptance test (FAT), where eight units were tested under full load for eight hours. As part of this process, four of the tests were wit-nessed by a surveyor from the owners of the vessel as well as the winch manu-facturer. Having successfully completed assembly and testing, all 32 gearboxes were delivered, with eight being fitted to each winch assembly.

Jeff van Nobelen, project engineer at Brevini, comments, “The scale and capac-ity of the Pieter Schelte demanded a high powered, high quality transmission with a proven track record. We were able to provide a flexible, adaptable product that could be designed around their require-ments and still delivered at a competitive price and on realistic time scale.”

gear profile

Q:Tell us a little bit about the his-tory of Klingelnberg. When was Klingelnberg originally founded? When and why did the company get involved in the gear industry?

A:Klingelnberg was founded in 1863 — originally as a metal trad-ing company. We have been locat-ed in Hückeswagen, Germany since 1916. Having started with the production of tools and machine knives in 1908, the com-pany moved to Hückeswagen and eventually became involved with gearing technology. Consequently, in the 1920s we started designing and producing machines for bevel gear manufacturing based on the palloid system.

Q:Please describe how Heinrich Schicht invented Klingelnberg gearing and the challenges he originally faced with his invention.

A:Heinrich Schicht converted the basic principle of hobbing from cylindrical gears to spiral bevel gears. Instead of a cylindrical hob used for cylindrical gears, he applied a conical hob for bevel gears. His idea remains the basis for all further developments in this industry. The patent for his idea was applied for in 1921. It allowed the company to grow and go global from that point on.

Q:For historical perspective, please describe the significance of the Klingelnberg cyclo-palloid tooth form and its development; i.e., why was it developed, how does it fit in the overall scheme of spiral bevel gear production, and, histor-ically, how has it competed with other tooth forms?

A:First of all, cyclo-palloid is a wide-ly used, universal gearing prin-ciple. The cutting tool is not spe-cifically designed for a dedicated gear set. Rather, it is applicable for any ratio in a defined module range. This makes cyclo-palloid profitable and thus competitive, especially when the customer has small batch sizes and a high vari-ety of gear designs.

Q:From a gear design perspective, cyclo-palloid always creates par-allel tooth heights. This is impor-tant to mention since there are other gearing systems that apply a tapered tooth height. The length-wise shape of the teeth, combined with the optimal tool diameter, provide the best conditions for maximum strength of a cyclo-pal-loid gear.

A:One important feature of cyc-lo-palloid is the hard finishing option. The machine executing the soft cutting operation is able to perform a hard cutting process called “HPG skiving” — result-

ing in very geometrically precise gears to meet the highest quality demands.

Q:What were the significant technol-ogy contributions of Oerlikon, and how does that technology fit with today’s operations?

A:Klingelnberg has always been very strong in the market of univer-sal applications in industrial gear boxes. But decades ago, on the other hand, Oerlikon introduced the face hobbing principle to pro-duce gears for automotive applica-tions. This latter process provided significantly higher productiv-ity, but every individual design required a dedicated tool.

Oerlikon has been the market leader in lapping technology from the beginning of the 1990s. Since bevel gears for industrial gear boxes are mainly ground or skived, Klingelnberg did not ini-tially have enough expertise in the area of high-volume products and lapping. But, by combining Oerlikon’s market knowhow and Klingelnberg’s experience in CNC machine design, the group became a full-service supplier for bevel gear manufacturing in the auto-motive industry.

Interview withJan Klingelnberg

THE LATEST

This the first of a new series of Gear Technology profiles of individuals you should know in the gear industry.


Q:What are the keys to success for a family-run business (now in its seventh generation) operating on a global scale?

A:There are some valuable, inherent advantages to being a family-run business. Time, for example, is one key factor:we take our time — in both marketing new developments and patiently striving for conti-nuity — even in tough periods. On the other hand, our independence allows us to make quick decisions, even concerning strategic mat-ters. Another factor that must not be underestimated is our commit-ment to our local community and our heritage — important values that contribute to our staff’s iden-tification with the company.

Q:How has the gear industry evolved since you took over as CEO in 2004?

A:With regard to the markets in general, what stands out is the increasing quality demands for gears, especially in the automotive industry. For us as a company in particular, it is the transition from machine tool supplier to solutions provider for technology partner-ships. Application support along the entire process chain is what customers demand today.

Q:Why was the recent acquisi-tion of Höfler important for Klingelnberg?

A:Put simply, it was the logical com-pletion of Klingelnberg’s prod-uct range, adding cutting and grinding machines for cylindrical gears — both in terms of applica-tion areas and customer indus-tries served. The addition of Höfler Maschinenbau allows us to sig-nificantly advance in reaching our strategic goal of being able to provide all gear technologies as a one-stop shop.

Q:What synergies have been achieved in the takeover of Höfler?

A:Of course we benefit from certain technological expertise, and the complementary product range of the two partners. Höfler’s strong R&D focus is a major asset to our company.

Q:What regions of the world are showing the most promise for growth in gear manufacturing, and why?

A:One main factor that drives demand in the industry is, of course, the growth of the auto-motive sector in certain countries such as Russia, India, China and Brazil. This is nothing unique to gear manufacturing, of course, as it applies to several other indus-tries as well.


gear profile JAN KLINGELNBERG

Q:What innovations, changes or trends do you see in the coming years that will impact the world-wide gear manufacturing commu-nity?

A:The development of electric drives vs. combustion engines in auto-motive engineering will have a growing impact on our industry, for sure. Other than that, efficien-cy, noise reduction, unit costs and stable manufacturing processes will be the focus of development work — both for us and our cus-tomers.

Q:What are your goals for the Klingelnberg group over the next five years? Can you discuss your expansion plans in Germany? Do you have plans to expand manu-facturing outside of Germany?

A:Certainly one important step is relocating our site in Hückeswagen to new, nearby facil-ities; this will take place gradually during the next decade. In gener-al, we will keep striving to deliver product innovations, just as we have been doing in the past or at an even higher level.

Q:How have your customers’ demands changed in recent years?

A:What sticks out is the ever-grow-ing demand for more efficiency in production. For this reason we introduced our trademarked 2 E efficiency label. The label stands both for high-performance and energy-efficient machines. In this context we are an active mem-ber of the sustainability initiative, Blue Competence (Ed.’s Note:The Blue Competence machine tools initiative increases awareness and knowledge of sustainability and raises the energy efficiency bar in the European machine tools indus-try. The initiative offers a com-mon platform to European machine tool companies and coordinates efforts for the development of energy and resource-efficient solutions).

Another important factor is mak-ing our machines easy to operate while providing ever more com-plex technologies. With our cus-tomers being globally active, they need to rely on reproducible qual-ity worldwide — no matter who operates the machine. Easy opera-tion of our machines minimizes costly human errors and, in the final analysis, reduces costs per unit.

Q:What is Klingelnberg doing to accommodate those demands?

A:We listen to the markets and develop our solutions accordingly. This is, in our view, the only viable way to develop products that help customers reduce cost-per-unit and at the same time provide high quality — certainly two of their main goals.

Q:How has your North American dis-tribution, sales and service organi-zation changed over the last sev-eral years?

A:We have established new sales capacities and have expanded our network through Höfler based on their already strong presence in the USA.

Q:Describe the importance of Klingelnberg’s unique gear manu-facturing capabilities. (Specifically, regarding delivery time; quality; price; materials; new-application designs, etc.)

A:Customer satisfaction is the result of the optimal interplay between factors such as delivery time and reliability, quality of materials and service, and pricing. We are con-vinced that cheap “solutions” go against this interplay and thus against customer satisfaction. Furthermore, our team of innova-tive engineers lays the ground-work for refined solutions and new developments.

Q:Given your reputation for recruit-ing and retaining skilled workers, do you have any concerns in that regard?

A:In this context we find two trends especially important:first, we cooperate closely with local and regional schools and universities; second, we continuously invest in internal training and further edu-cation to strengthen our staff. This is something that will be of grow-ing importance in our market, so we are well-prepared for future developments.

One took place in Germany while the other took place simultaneously in Indianapolis, Indiana. Both trade shows—EMO Hannover and AGMA’s Gear Expo—were successful for the gear market based on end-of-show numbers. While EMO Hannover represented the entire met-alworking industry, Gear Expo was a more focused, gear specific experience. Representatives from companies such as Gleason, Star SU, Liebherr, Klingelnberg, Kapp, MHI, Reishauer, Ingersoll, DMG, EMAG and Sandvik Coromant made sure personnel were available at both shows to offer the latest technologies and advancements in gearing.

EMO Attracts Just Under 145,000 Trade VisitorsEMO Hannover 2013 came to a success-ful close on Saturday, September, 21 in Germany. “This year’s EMO raised the bar in all areas,” remarked EMO General Commissioner Carl Martin Welcker at the end of the fair in Hannover. “With more visitors, more business and more international drawing power, this EMO has proven even more successful than last time around, impressively under-scoring the event’s status as the world’s premier trade fair for the international metalworking industry,” he said. More than 2,100 exhibitors from 43 different countries were on hand in Hannover to showcase their innovations to industrial users from around the world under the event’s keynote slogan of “Intelligence in Production.”

Over the six days of EMO, the Hannover event attracted a total of just under 145,000 trade visitors from over 100 different nations. “Visitors from outside Germany numbered more than 50,000, or one in three. Attendance from Europe was up markedly. European industry is rebounding, and keen on investing in manufacturing technology,” Welcker noted.

Italy, Switzerland, Sweden, the Netherlands and Russia topped the

attendance figures for the European con-tinent. By a very wide margin, China accounted for the largest number of visitors from Asia, followed by Japan, Taiwan and India.

According to a visitor survey, one out of every two attendees had a managerial status, with the authority to make pur-chasing decisions for their organizations. They reported their main motivation in attending as wanting to expand and modernize their production machinery. One out of every five visitors reported placing an order at the show. A simi-lar number, at 20 percent, intended to finalize purchases after the event, with the figure being double in the case of customers from abroad. According to Commissioner Welcker: “Many pur-chase orders, including several high-volume deals, were signed right here in Hannover.” Exhibitors were also antici-pating brisk after-show sales. Among all visitors with firm investment plans, each placed between four and five orders dur-ing their time at EMO. This figure was even higher than for the previous event two years ago, which took place in the midst of an economic upturn.

EMO Hannover 2013 succeeded again in covering the entire bandwidth of the global machine tool market. “This is where manufacturing experts come to

explore ways of improving operations,” Welcker said. Visitors were particular-ly interested in solutions for boosting energy and resource efficiency, as well as user-friendly equipment and the intel-ligent integration of machines – in addi-tion to the evergreen themes of cutting manufacturing costs and increasing flex-ibility.

In addressing these topics and more, the rich array of solutions and outstand-ing expertise on offer by EMO exhibitors added up to a high rate of visitor satis-faction. More than ever, EMO Hannover impressed its audience as the interna-tional flagship flair for “Intelligence in Production.” The average length of stay by visitors went up slightly to two full days, attesting to EMO’s drawing power as an event that delivers maximum cov-erage. The next EMO will be staged from 5 to 10 October 2015 in Milan, under the motto “Let’s build the future.”

India needs machine tools worth more than 2 billion euros a year, and imports most of them. In the past five years alone, machine tool consumption has risen by almost 25 percent. The potential for further growth remains high in the medium term. “There are many good reasons for the VDW to turn the spot-light on the Indian market at the EMO Hannover,” says Martin Kapp, chairman

of the VDW (German Machine Tool Builders’ Association), Frankfurt am Main. On September 18, 2013, the VDW organized the “EMO Focus on India” event, entitled “Strategic involvement of numerous major users, exploitation of potentials still restricted by structural deficits.” The empirically based half-day seminar was designed to inform interna-tional visitors who want to expand their operations in India, on the idiosyncra-sies of this market.

The Indian government has to mod-ernize its energy generating plants and ensure massive expansion of the road and railway networks if it wants to achieve its ambitious growth tar-gets of 5 percent and more in the years ahead. Against this background, promi-nent international machine tool users are investing on the subcontinent for appropriate strategic positioning. The giant automaker Daimler, for example, is massively upsizing its production facil-ity in Chennai, with the aim of manufac-turing sturdy, affordable models for the Indian market. In the aircraft compo-nent supplier industry, India itself pos-sesses some highly competent vendors like Tata, Hinduja and HAL, who man-ufacture components for the aircraft’s interior and operate in what is called the

MRO (Maintenance, Repair & Overhaul) category, and are entrusted with non-strategic development projects. By 2028, the market volume for the MRO cat-egory alone in Asia/Pacific, China and India is predicted to exceed the figure for North America.

The major users of machine tools in India will be increasing their capital expenditure on machinery in 2013/2014 by an average of more than 16 and 19 percent respectively. This means rises of 4 and 10 percent respectively in machine tool consumption in the same period. “International machine tool manufac-turers will be well advised not to neglect India”, says Martin Kapp. “If the China boom runs out of steam one day, India may become much more important. And then it will be pay-off time for those who’ve been consistently showing the flag,” he adds.

Gear Expo Earns 11 Percent Attendance IncreaseNational Trade Productions, Inc. (NTP), recently announced nota-ble show growth metrics for its cli-ent, the American Gear Manufacturers Association (AGMA). The association’s biennial Gear Expo, held September 17-19, 2013 at the Indiana Convention

Center in Indianapolis, sold out the exhibition floor by attracting 219 exhib-iting companies across 52,500 net square feet of exhibit space. This milestone rep-resents a 26 percent increase in exhibit-ing companies and a 29 percent increase in exhibit space over 2011. The event also united more than 3,400 industry professionals in 2013 (an 11.8 percent increase in attendance over 2011) and earned an 82 percent rebook rate during 2015 exhibit space selection.

“Gear Expo is a high-quality event focused on precision, power and part-nerships,” said Andrew Ortale, executive vice president of NTP. “For more than two decades, gear professionals have relied on the event—and its exhibitors—to provide the latest industry informa-tion, technology, products and servic-es to help expand and streamline their businesses. The event continues to deliv-er real strategic value as demonstrated by its significant achievements and expan-sion, and we anticipate even greater suc-cess in 2015 as we celebrate AGMA’s 100-year anniversary.”

For three days, gear buyers and man-ufacturers met face-to-face to discuss industry trends, demo the latest tech-nologies and to network and build rela-tionships that benefit their respective companies. NTP facilitates and manages the operations and exhibit sales for the event. Gear Expo 2015 will take place October 20-22, 2015 at the Cobo Center in Detroit, Michigan.

Notable exhibitors included Bevel Gears India, Shanthi Gears, Virgo Communications and Exhibitions and Mackeil Ispat & Forging Ltd. For a full report on EMO Hannover, visit www.emo-hannover.de. For a full report from Gear Expo, visit www.agma.org.

James Gleason laid the foundation for Gleason Works India on November 6, 1996. “Initially, Gleason Works India undertook sales and service support for Gleason products manufactured in other operations, but within two years added the manufacture of bevel gear cutting tools to serve the domestic market,” says K.P. Soundararajan, director and general manager of Gleason Works India. “This was the first availability of Gleason cut-ting tools produced on Indian soil rather than being imported, a move that was welcomed by the consuming industries, including the automotive market.”

Over time, Gleason was able to lever-age that reputation with the addition of cylindrical gear machines and gear metrology equipment, produced at their facilities in the U.S., Europe and Asia. “I would say that the broad spectrum of gear-making processes combined with the domestic presence have enabled Gleason to acquire a unique place in India as a dependable machine tool and service provider,” Soundararajan s ay s . “S om e of t h e c om -

panies are in the major commercial vehi-cle sector and include Tata Motors and Ashok Leyland, and in the steel manu-facturing industries and their respec-tive machine shops in companies like Tata Steel and Bhilai Steel. These plants require flexibility and simple technology to have the parts made quickly in house.”

According to Soundararajan, the Indian gear industry evolved several decades ago since the Second Five-Year Plan in the 1950s, during which domes-tic production of mechanical compo-nents was encouraged to support the sugar, cement and steel industries. Gears were one of the key mechanical com-ponents. The evolution continued as it moved to the automotive industry where joint ventures took place between Tata and Daimler, Premier and Fiat and so on, giving exposure to the need for more accurate gears to be manufactured and supplied during the 1960s. The growth of the automotive industry has contin-

ued to progress, along with the need for more refined

gear production equip-ment and technology,

which Gleason could provide.

“With the advent of growth in heavy engineering and railways, the original equipment manufacturers started sup-porting the gear industry, and in many cases they themselves had gear produc-tion equipment. As Gleason has been a pioneer in providing gear technology to the market, they assumed a role in train-ing the customer in the art and science of gear-making,” Soundararajan says.

Gleason Works India TodayToday, Gleason Works India has around 65 employees comprised of technical, commercial and support service staff. “Gleason products have been known to this market for many years, from the days when Gleason was primarily a pro-ducer of mechanical machines for pro-ducing straight bevel, spiral bevel and hypoid gears,” says Soundararajan. “The company gained a solid reputation in India as a producer of quality products that were well-supported.”

Taking the Next StepGleason Offers Latest Manufacturing Technology for Indian MarketMatthew Jaster, Senior Editor

K.P. Soundararajan is director and general manager of Gleason Works India.


Quality is the premier requirement in any industry and gear application in today’s market. “We have seen this in the realization of customers who use Gleason products in the energy sector or engineering or earth moving or aero-space applications,” Soundararajan says. “Gleason India supports the customer with total solutions. This means not only the ability to offer virtually every gear making process, but also to offer every element of those solutions. We provide not only the machine but also the pro-cess and the cutting tools and workhold-ing to optimize the process.”

Customer expectations continue to get higher in all markets and India is no exception. Globalization has caused many companies to transfer production to India, and Gleason India plays a key role in getting the transferred equipment up and running, and then supporting production thereafter. “We continue to adjust our organization and capabilities to meet this ever increasing demand, and we constantly look for opportunities to strengthen ourselves for the future,” Soundararajan says.

He continues, “It is well known that the Indian economy is presently going through a rather sluggish period, and the slowdown in the economy has taken its toll on manufacturing efficiency and capacity utilization in industry. What we hear most often is that the expectation of the manufacturing industries is for a bet-ter 2014 and beyond. However, we envi-sion the automotive industry growing at a more gradual and steady pitch rather than jumping ahead, because the indus-try consists of several manufacturers in several categories of vehicles. This could be followed by progress in the trend of defense equipment privatization that can provide opportunity for jobbing indus-tries. This calls for absorption of relevant technologies on the manufacturing pro-cess and Gleason can provide an ade-quate support in this endeavor.

“Overall we can assume that we should wait and watch how 2014 can form a stepping stone for further years ahead, since the demand within the country is more than the manufactur-ing industry can sufficiently address. Opportunities for export in the com-ponent industry have a possibility to grow according to statement of various experts in the industry by suitably merg-ing the MNCs working together with Indian manufacturing industry to keep India as a hub for taking the finished components to other parts of the devel-oping economy such as Brazil, Argentina and on the eastern side towards Thailand and Indonesia.”

Latest Technology DevelopmentsSome recently-introduced technol-

ogies have been in the energy sector, in the form of profile grinding of gears using the latest technology innovations and necessary software for optimizing the grinding process and user comfort. The introduction of dry cutting process-es with carbide for automotive axle bevel gear sets is another example, as well as the production of cylindrical transmis-sion gears using dry hobbing with inte-grated chamfering and deburring.

Additionally, Gleason Works India is moving forward in the expansion of the products manufactured in India.

“We have started manufacturing Genesis gear hobbing machines, which


feature TAKING THE NEXT STEP

are state-of-the-art equipment for pro-duction of gears, to the exacting require-ments of the auto industry, up to the pas-senger car level now,” Soundararajan says. “These machines are offered in such a way that they can suit gear jobbers and component suppliers as well, by adding or eliminating some of the machine optional equipment and peripherals. Moving for-ward we are strengthening ourselves in workholding manufacture with Gleason design. With our planned approach to manufacturing cylindrical gear cutting tools, we are confident that the combined offer of the machine and tooling solution will enable the customer to find a one-stop solution.”

Future Business SuccessSince its inception, the Indian machine tool industry has been largely dependent on the domestic market. “This is fine so

far but we believe that with increased local competition within India, our industry must become global. This is the quest for survival and growth within the country. Cost competitiveness has to be the key and therefore this should give way to supplement local manufacture wherever possible in products that seek technology transfer in order to become attractive to customers,” Soundararajan says. “With the currency presently being weak against a strong dollar or euro, the cost of capital goods is a concern to the manufacturing industry. The machine tool market is aware of this and needs to address how we can be competitive, and to find every way and means to accom-plish this,”

Soundararajan believes it’s getting bet-ter, however.

“The process of gear making has grad-ually shifted from the OEM desk to a

strong support base of component or assemblies in India much like Europe decades ago. This provides an opportu-nity to support customers in the various segments by offering a single-source solu-tion for all the aspects of high quality gear production. We are witnessing this in our day-to-day lives and we feel reasonably confident that this concept should con-tinue to grow in our industry.”

Bundling machine tool packages is one of Gleason’s tried and true business practices. “For example, we can provide a gear measurement machine, appro-priate software for various inspection requirements, suitable workholding and high precision mandrels, and also offer training in gear inspection technology to make our customer completely self-suffi-cient. In a similar way the answer can be given for a grinding solution or cutting


operation or a fine finishing gear honing solution.”

Soundararajan says that the manufac-turing sector currently constitutes approx-imately 15-16 percent of the total GDP of India. The expectation of both the government and the private sector is to grow this figure to a higher level of per-haps 25 percent in 5-6 years’ time. “This will require much planning and a lot of hard work. Some of the questions aris-ing at open forums include how to evolve sustainable manufacturing at competi-tive pricing, and how to bring back use-ful items from manufactured products and recycle them to make the new parts, without the need for additional raw mate-rial. Technologies that use less resource of nature or less energy are valued. Lower power consumption, less oil consumption, and recycling some of the useful non-worn items back to use rather than manu-facturing again, are good examples. Since these are concerns opined by various experts and driven thru minds of users I am sure that everyone will work towards these goals.”

Additionally, the opportunity for improving the manufacturing industry through exports will continue to grow, and cross-border know-how and migra-tion of benefits will increase, all of which can enhance the flexibility and growth of manufacturing, notes Soundararajan.

“In my opinion, we should support some of the concepts of sustainability by using various methods to eliminate waste of precious resources. This is becoming a major thrust in India as it is in most developed countries. In our own busi-ness, we should think of rebuilding and remanufacturing our products that have been already used in the industry, with rejuvenation of the product as a theme,” Soundararajan says. “Every manufactur-ing industry should think along these lines to become successful.”

Although a comprehensive on-site gear-box inspection is desirable in many sit-uations, there may be constraints that limit the extent of the inspection such as cost, time, accessibility and qualified personnel.

Cost and shutdown time might be per-ceived as prohibitive by management, but catching a problem in its earliest stages can save time and money in the long run. While it may seem too diffi-cult to do a comprehensive inspection, a simple visual inspection of gear contact patterns through an inspection port can prevent future catastrophic failures. If in-house inspection expertise is not avail-able, an expert can be hired to perform the inspection and train personnel.

Overcoming constraints in order to allow an inspection can help to extend gearbox life and avoid catastrophic fail-ure. This might also save time, money, injury to personnel and damage to adja-cent equipment.

This article describes the equipment and techniques necessary to perform an on-site gearbox inspection.

Getting Prepared: Good Housekeeping is EssentialBefore beginning an inspection, prepare an inspection form for documenting your observations. It should be designed for your specific application. Next,

assemble the necessary equipment (see sidebar on page 14).

There are several sources of gearbox contamination, including those that are built-in, internally generated, ingressed, and added during maintenance. Many gearboxes operate in dirty environments. Therefore, good housekeeping meth-ods should be used during inspections. Areas around inspection ports and other openings should be cleaned before they are opened. Inspectors should take care not to drop anything into the gearbox. Shirt pockets should be empty and tools should be stored in a tool belt. Ports should never be left open during breaks and should be closed and secured after the inspection is complete.

Walk-around visual inspection. You should perform a thorough external examination before the gearbox inspec-tion port is opened. Use an inspec-tion form to record important data that would otherwise be lost once clean-ing is completed. For example, before cleaning the exterior of the gear hous-ing, inspect it for signs of overheating, corrosion, contamination, oil leaks and damage. Measure the tightening torque of structural fasteners that carry signif-icant loads, such as torque arm bolts. Look for evidence of movement, includ-ing cracked paint or fretting corrosion at structural interfaces. Note the condition

of the fasteners and inspect load-bearing surfaces of components for fretting cor-rosion or other evidence of movement.

Detecting OverheatingThe following are signs of overheating:• Smoke from shafts, seals or breathers• Discolored or burnt paint on housings• Water sprayed on the housing or shafts

evaporates quickly, boils or crackles• Temper colors on unpainted surfaces• Melted plastic components, such as

shipping plugs• Low oil level in sight glass or on dip-

stick• Dark oil in sight glass or on dipstick• Foam in sight glass• Water in sight glass or sludge on filter

element (may indicate oil cooler fail-ure)

• Metal chips on magnetic plugs, chip detectors or filters (may denote gear or bearing failure caused by overheating)

Methods for Inspecting a Gearbox Visual walk-around• Visual inspection through inspection

ports• Borescope inspection• Measure temperature

– Thermometers – Resistance temperature detector (RTD) probes

– Thermography• Measure oil pressure• Measure sound and vibration

To help you detect overheating, use this checklist:• Visually inspect the gearbox exterior

for signs of overheating.• Record temperatures from gear-

box thermometers, thermocouples or resistance temperature detectors (RTDs).

• Measure oil sump temperature.• For pressure-fed systems with an oil

cooler, measure temperature at the gearbox oil inlet and outlet, as well as the cooler water inlet and outlet.

• Estimate gearbox housing and shaft temperatures using water spray.

• Survey the gearbox housing tempera-ture by touching it with the palm of your hand and using temperature-sensitive paint, crayons and labels, or a digital thermometer probe.

• Check the gearbox housing tempera-ture using an infrared thermometer or infrared imaging camera.

• Analyze gearbox oil for signs of oxida-tion or thermal degradation using on-site and laboratory tests.

• Analyze gearbox oil using particle counters, spectrometric analysis and ferrography to detect wear debris.

• Inspect internal gearbox components through inspection ports for signs of overheating, misalignment, inad-equate backlash, inadequate bearing endplay or oil oxidation.

• Measure gearbox sound and vibration and compare to allowable limits.Inspect the breather. The breather

should be located in a clean, non-pres-surized area away from contaminants. It should include a filter and desiccant to prevent ingress of dust and water. Also, ensure that the breather is shielded from water during wash-downs.

Check shaft seals. Look for oil leaks at the shaft seals. If there are signs of oil leakage, the seals are probably allowing ingression of dust and water. If the gear-box has labyrinth seals, it should have external seals such as V-rings to prevent contaminant ingression.

Inspect structural interfaces. Figure 1 shows cracked paint at an interface, which indicates there was movement. The 45° direction of the cracks sug-gests the component on the right moved downward relative to the component on the left.

Examine through inspection ports. Examine the inspection port cover and determine whether all bolts are tight and the cover is properly sealed, or if there is oil leakage. Only qualified person-nel should be allowed to open inspec-tion ports; in some cases it is necessary to secure the ports with padlocks to enforce security.

Clean the inspection port cover and the surrounding area. Remove the cover, being careful not to contaminate the gearbox interior. Count the bolts and store them in a separate container so there is no chance they will fall into the gearbox. Observe the condition of the gears, shafts and bearings.

If the gears or bearings are damaged but still functional, management may decide to continue operation and mon-

itor damage progression. In this case, the gear system should be continuously monitored. You should also make certain there are no risks to human life.

For critical applications, examine the gears with magnetic particle inspec-tion to ensure there aren’t any cracks that prevent safe, continued operation. If there are no cracks, you should peri-odically perform a visual inspection and measure temperature, sound and vibra-tion.

Collect samples of the lubricant for analysis, examine the oil filter for wear debris and contaminants, and inspect magnetic plugs for wear debris.

The best place to take an oil sample from a gearbox is as close to the gear-set as possible. Using a minimess (Ed.’s note: Hydrotechnik’s patented ball seal-ing threaded test point and plug-in cou-pling) sample port with tube extension will allow you to mount the sample port in the drain and manipulate the tube so that it terminates exactly where you want it.

The rule of thumb for installing sam-ple port tube extensions is to keep the end of the tube at least two inches away from any static or dynamic surface.

You will need to flush the entire com-bination of tube extension, minimess sample port, sample port adapter and sample tube before you take your sample for analysis. Flush at least 10 times the volume of all the components prior to taking the sample for analysis. This typi-cally works out to three or four ounces of fluid for a sample port with a tube exten-sion of 12 inches.

To prevent further damage to the gears and bearings from wear debris, replace

the filter element and then drain, flush and refill the reservoir with new lubri-cant. Continue to monitor lubricant properties during operation and repeat the maintenance if necessary.

If cracks are found or the damage is severe enough to warrant removal of the gearbox, measure shaft coupling endplay and alignment before removing the gear-box. Note the condition and loosening torque of fasteners, including coupling and mounting bolts. To check for pos-sible twist in the gear housing, install a dial indicator at each corner of the gear-box and then measure movement of the mounting feet as bolts are loosened. If there’s no twist, each indicator will record the same vertical movement. If there is twist, calculate the twist from relative movements.

If no obvious damage is detected, doc-ument the condition of gears and bear-ings with photographs, sketches and written descriptions. Also, record gear tooth contact patterns for future refer-ence (see Recording Gear Tooth Contact Patterns section).

Measure gear backlash and shaft end-play. Measure gear backlash by mount-ing a dial indicator so it is similar to a pinion tooth profile; block the gear to prevent its rotation and rock the pinion through the backlash.

To measure shaft endplay, mount a dial indicator at the end of a shaft and move the shaft in the axial direction. In most cases, this requires a fixture with a ball bearing on the central shaft that allows pushing and pulling the shaft while it is rotated to seat the bearing rollers.

Gear mesh alignment. Gears have maximum load capacity when the gear shafts are perfectly aligned and the transmitted load is uniformly distrib-uted across the entire active face width. Unfortunately, many factors, such as design issues, manufacturing accura-cy, deflections, thermal distortion and external effects may combine to cause misalignment of the gear mesh. The result is that the gears are misaligned and the load distribution is not uniform.

Gear tooth contact patterns. It is important to inspect gear tooth con-tact patterns because they can disclose gear mesh misalignment. The inspection should be done during commissioning of the gearbox to catch misalignment before it causes damage. Inspections should be regularly repeated to determine any changes in contact patterns caused by problems such as bearing failure.

What to look for. Watch for heavy contact at the edges of the contact area — especially at each end of the pinion and gear face, at the tips of the teeth, and along the roots of the teeth at the start of

active profile (SAP). Determine if there are wear steps at the tooth ends, tips or the SAP. The pinion is often wider than the gear, and if there is misalignment, a wear step is likely to be at either end of the pinion. Severe misalignment usually causes macropitting.

Recording gear tooth contact patterns. If there’s evidence of gear misalignment, such as macropitting concentrated at the ends of the teeth but no broken teeth or other failures that would prohibit rotating the gears, record the gear tooth contact patterns. The way gear teeth touch indi-cates how they are aligned. Tooth con-tact patterns can be recorded under load-ed or unloaded conditions. No-load pat-terns aren’t as reliable as loaded patterns for detecting misalignment because the marking compound is relatively thick. In addition, no-load tests don’t include mis-alignment caused by load, speed or tem-

perature. Therefore, if possible, follow any no-load tests with loaded tests.

Recording no-load contact patterns. For no-load tests, thoroughly clean and paint the teeth of one gear with a soft marking compound and then roll the teeth through the mesh so compound transfers to the unpainted gear. Turn the pinion by hand while applying a light load to the gear shaft by hand or a brake. Use clear tape to lift transferred patterns from the gear and mount the tape on white paper to form a permanent record.

The compound PT-650 tooth marking grease from Products/Techniques Inc. works best. Scotch No. 845 book tape (two inches wide) is preferred for lifting contact patterns.

Figure 6 shows contact tapes that indi-cate a contact pattern wandering from centered in some sectors of the gear to biased, toward the left end of the face width in other sectors. This type of mis-alignment is caused by run-out of the gear; it can only be corrected by replac-ing the gear with a more accurate one.

Recording loaded contact patterns. For loaded tests, thoroughly clean the teeth with a solvent and acetone. Paint several teeth on one or both gears with a thin coat of machinist’s layout lacquer (DYKEM). Run the gears under load for sufficient time to wear off the lac-quer and establish the contact pattern. Photograph the patterns to obtain a per-manent record.

If possible, record loaded contact pat-terns under several loads, such as 25, 50, 75 and 100 percent of full load. Inspect the patterns after running about

one hour at each load to monitor how the patterns change with load. Ideally, the patterns shouldn’t vary with load. Optimum contact patterns cover nearly 100 percent of the active face of the gear teeth under full load, except at extremes along tooth tips, roots and ends, where contact should be lighter as evidenced by traces of lacquer.

Think of on-site gearbox inspections as preventative maintenance. Problems caught early and corrected can prevent catastrophic, costly and dangerous fail-ures down the road.

Recording MicropittingA permanent record of micropitting can be obtained by rubbing fine graphite into micropitted areas and lifting the graphite pattern with transparent tape. The pro-cedure is as follows:1. Clean the tooth by rubbing with a

clean, lint-free cloth soaked in fast-drying solvent.

2. Place a clean lint-free cloth on a flat surface and rub a drafting pencil on a file or sandpaper to coat the cloth with graphite.

3. Rub the entire tooth surface with the cloth so graphite covers micropitted areas, top-land and edges of the tooth.

4. Rub the entire tooth surface with a clean lint-free cloth to remove loose graphite.

5. Place a length of transparent tape over the entire tooth. Allow the tape to fold over the edges and top-land to define the boundaries of the tooth. Scotch No. 845 book tape works best.

6. Rub the back of the tape with a clean cloth to ensure intimate contact with the tooth surface.

7. Starting at one end, carefully peel the tape from the tooth.

8. Place one end of the tape (with adhe-sive side down) on white paper and carefully spread the tape across the paper. Micropitted areas will appear as dark gray, machining marks as light-er gray, and polished areas will look white.

9. Annotate the record to fully describe tooth location and orientation.

Drive and Motor BasicsAllen Bradley (a Rockwell Automation company)

IntroductionAn adjustable speed drive is a device that controls speed and direction of an AC or DC motor. Some high-performance drives are able to run in torque regulation mode.

DC DrivesDC drive control system. A basic DC drive control system generally contains a drive controller and DC motor as shown (Fig. 1).

The controls allow the operator to start, stop and change direction and speed of the motor by turning potenti-ometers or other operator devices. These controls may be an integral part of the controller or may be remotely mounted.

The drive controller converts a 3-phase AC voltage to an adjustable DC voltage, which is then applied to a DC motor armature.

The DC motor converts power from the adjustable DC voltage source to rotat-ing mechanical force. Motor shaft rota-tion and direction are proportional to the magnitude and polarity of the DC voltage applied to the motor.

The tachometer (feedback device) (Fig. 1) converts actual speed to an electrical signal that is summed with the desired reference signal. The output of the sum-ming junction provides an error signal to the controller and a speed correction is made.

DC MotorsThe following are the four basic types of DC motors and their operating charac-teristics:

Shunt-wound. Shunt-wound motors have the field controlled separately from the armature winding. With constant armature voltage and constant field exci-tation, the shunt-wound motor offers rel-atively flat speed-torque characteristics. The shunt-wound motor offers simplified control for reversing, especially for regen-erative drives.

Figure 2 Shunt-wound DC motor.

Figure 3 Series-wound DC motor.

Figure 4 Compound-wound DC motor.

Series-wound. The series-wound motor has the field connected in series with the armature. Although the series-wound motor offers high starting torque, it has poor speed regulation. Series-wound motors are generally used on low speed, very heavy loads.

Compound-wound. The compound-wound DC motor utilizes a field winding in series with the armature in addition to the shunt field, to obtain a compromise in performance between a series- and a shunt-wound type motor. The com-pound-wound motor offers a combina-tion of good starting torque and speed stability.

Permanent-magnet. The permanent magnet motor has a conventional wound armature with commutator and brush-es. Permanent magnets replace the field windings. This type of motor has excel-lent starting torque, with speed regula-tion slightly less than that of the com-pound motor. Peak starting torque is commonly limited to 150 percent of rated torque to avoid demagnetizing the field poles. Typically these are low horsepower.

Armature voltage controlled DC drives are capable of providing rated current and torque at any speed between zero and the base (rated) speed of the motor. The motor output horsepower is directly pro-portional to speed (50 percent horsepow-er at 50 percent speed).

The term constant torque describes a load type where the torque require-ment is constant over the speed range. Horsepower at any given operating point can be calculated with the following equation:

(1)

HP = Torque ∙ Speed5250

where:Torque is measured in Lb – FtSpeed is measured in RPM

Constant HorsepowerArmature and field-controlled DC

drives. The motor is armature voltage controlled for constant torque-variable HP operation up to base speed. Above base speed, the motor is transferred to field current control for constant HP-reduced-torque operation up to max-imum speed.

Operation above base speed. One characteristic of a shunt-wound DC motor is that a reduction in rated field current at a given armature voltage will result in an increase in speed and lower torque output per unit of armature cur-rent.

AC DrivesThe speed of an AC motor is deter-mined for the most part by two factors: the applied frequency and the number of poles.

(2)

N = 120fP

where: N = RPM f = Frequency P = number of poles

Some motors, such as in a typical pad-dle fan, have the capability to switch poles in and out to control speed. In most cases, however, the number of poles is constant and the only way to vary the speed is to change the applied frequency. Changing the frequency is the primary function of an AC drive. However, one must consider that the impedance of a motor is determined by the inductive reactance of the windings, in which:

(3)XL = 2π fL

where: XL = Inductive reactance in Ohms f = Line frequency L = Inductance

This means that if the frequency applied to the motor is reduced, the reac-tance and therefore impedance of the motor are reduced. In order to keep cur-rent under control, we must lower the

technical

applied voltage to the motor as the fre-quency is reduced. This is where we get the phrase “volts-per-hertz.” The most common method of controlling the applied voltage and frequency is with a pulse-width-modulated “PWM” tech-nique. With this method, a DC voltage is applied to the motor windings in time-controlled pulses in order to achieve cur-rent that approximates a sine wave of the desired frequency. IGBTs (isolated gate bipolar transistors) are the latest tech-nology and offer the ability to switch the PWM pulses very quickly. This allows several thousand pulses to be applied in one cycle of the applied motor frequency. More pulses in a given cycle result in a smoother current waveform and better motor performance.

AC Motor TypesAC motors can be divided into two main types: induction and synchronous. Induction motors are most common in industry. Synchronous motors are spe-cial-purpose motors that do not require any slip and operate at synchronous speed.

The induction motor is the simplest and most rugged of all electric motors. The induction motor is generally clas-sified by a NEMA design category. But before a meaningful discussion on NEMA-type motors can take place, we should first look at what makes up a speed-torque curve.

Anatomy of a speed-torque curve. Generally speaking, the following can be said about a speed torque curve when starting across the line. Starting torque is usually around 200 percent, even though current is at 600 percent; this is when

slip is the greatest. (Starting torque is also called blocked-rotor torque, locked-rotor torque or breakaway torque.) Such a large onset of current may cause the sup-ply voltage to dip momentarily, affect-ing other equipment connected to the same lines. To prevent this, large motors will connect extra resistors to inductors in series with the stator during starting. Extra protective devices are also required to remove the motor from the supply lines if an excessive load causes a stalled condition.

As the motor begins to acceler-ate, the torque drops off, reaching a minimum value — cal led “pull-up torque” — between 25–40 percent of syn-chronous speed (Point B). Pull-up torque is caused by harmonics that result from the stator windings being concentrated in slots. If the windings are uniformly distributed around the stator periphery, pull-up torque is greatly reduced. Some motor design curves show no actual pull-up torque and follow the dashed line between points A and C.

As acceleration continues, rotor fre-quency and inductive reactance decrease. The rotor flux moves more in phase with the stator flux and torque increases. Maximum torque (or breakdown torque) is developed at point C, where induc-tive reactance becomes equal to the rotor resistance. Beyond point C, (points D, E and F) the inductive reactance contin-ues to drop off — but rotor current also decreases at the same rate, thus reducing torque.

Point G is synchronous speed and proves that if rotor and stator are at the same speed, rotor current and torque are zero.

At running speed the motor will oper-ate between points F and D, depending on load. However, temporary load surges may cause the motor to slip all the way back near point C on the “knee” of the curve.

Beyond point C the power factor decreases faster than current increases, causing torque to drop off. On the lin-ear part of the motor curve (points C to G), rotor frequency is only one-to-three Hertz — almost DC. Inductive reactance is essentially zero and rotor power fac-tor approaches unity. Torque and current now become directly proportional — i.e., 100 percent current produces 100 percent

Figure 7 Motor speed and load characteristics.

Figure 8 Speed torque curve.


torque. If a 1-HP motor has a nameplate current of 3.6 amps, then when it draws 3.6 amps (at proper voltage and frequen-cy) it must be producing 100 percent of its nameplate torque. Torque and cur-rent remain directly proportional up to approximately 10 percent slip.

Notice that as motor load increases from zero (point F) to 100 percent (point E), the speed drops only 45–55 RPM — or about 3 percent of synchronous speed. This makes the squirrel cage induction motor very suitable for most constant-speed applications (such as conveyors) where, in some cases, 3 percent speed regulation might be acceptable. If better speed regulation is required, the squir-rel cage motor may be operated from a closed-loop regulator such as a variable-frequency drive.

The locked rotor torque and current, breakdown torque, pull-up torque and the percent slip determine the classifi-cations for NEMA design motors. The speed-torque curve and characteristics of each design are as follows:

Design A. Low-resistance, low-induc-tance rotor producing low starting torque and high breakdown torque. The low-resistance characteristic causes starting current to be high. It is a high-efficiency design; therefore the slip is usually three percent or less.

Design B. Higher impedance rotor pro-ducing a slightly higher starting torque and lower current draw. For this reason, Design B motors are a general-purpose-type motor and account for the largest share of induction motors sold. The slip of a Design B motor is approximately 3–5 percent or less.

Design C. Uses a two-cage rotor design — high-resistance for starting and low-resistance for running (Fig. 12). This creates a high starting torque with a nor-mal starting current and low slip. During starting most of the current flows in the low-inductance, outer bars. As the rotor slip decreases, current flows more in the inner, low-resistance bars.

The Design C motor is usually used where breakaway loads are high at start-ing, but are normally run at rated full load and are not subject to high overload demands after running speed has been reached. The slip of the Design C motor is five percent or less.

Figure 10 AC induction motor: Design B.

Figure 11 AC induction motor: Design C.

Figure 12 AC induction motor: Design D.


technical

Design D. Highest resistance rotor creating high slip, high starting torque and low starting current. Because of the high amount of slip the speed varies dra-matically with load. The slip of this type motor is approximately five to eight per-cent. This high slip characteristic relates to a low-efficiency design and a motor that runs hot.

Synchronous MotorsSynchronous motors operate at synchro-nism with the line frequency and main-tain a constant speed — regardless of load — and without sophisticated elec-tronic control. The two most common types of synchronous motors are reluc-tance and permanent magnet. The syn-chronous motor typically provides up to a maximum of 140 percent of rated torque. These designs start like an induc-tion motor but quickly accelerate from approximately 90 percent sync speed to synchronous speed. When operated from an AC drive they require boost voltage to produce the required torque to synchro-nize quickly after power application.

Also available in high-horsepower motors is the separately excited synchro-nous motor; this design requires a load-commutated inverter (LCI).

Wound rotor. Some large motors may have a “wound rotor,” allowing the motor characteristics to be altered by adding resistors in series with the rotor. This effectively lets the user define the motor torque curve as NEMA A, B, C or D. More resistance means higher slip and higher starting torque across the line, while using a low value of series-resis-tance results in lower slip and greater effi-ciency. Often the resistors will be present

for start-up and then jumped out while running.

In a case where a wound rotor motor is fed by an AC drive, the wound rotor con-nections should be permanently jump-ered (no series resistance added).

A motor rated for 60 Hz operation may be run at higher frequencies when powered by an AC Drive. The top speed depends upon the voltage limits of the motor and its mechanical balancing. 230 V and 460 V motors normally employ insulation rated for as much as 1,600 V, so the voltage limit is not usually a problem. An average two-pole industrial motor can safely exceed its base speed by 25 percent. Many manufacturers balance their three- and four-pole rotors to the same speed: 25 percent over the two-pole base speed. A four-pole motor may there-fore operate up to 125 percent over base speed before reaching its balance limit. A 60 Hz four-pole motor might run up to 135 Hz, whereas a 60 Hz two-pole motor would reach its balance limit at 75 Hz; both motors would run at the same RPM. Always contact your motor manufacturer if you plan to operate at these speeds.

Constant-voltage operation. What happens to the volts-per-Hertz ratio above rated frequency? If output frequen-cy is increased to 120 Hz with 100 percent voltage applied to the motor, the volts-per-Hertz of the drive is no longer 7.6 but rather 3.83. The same volts-per-Hertz ratio results when a line-started motor is operated at 60 Hz with only a 50 voltage applied (for reduced voltage starting). As might be expected, the effect on torque is the same; recall that torque varies as the square of the applied voltage:

(4)T = K1 xE2

As such, maximum torque at 120 Hz is only 25 percent of the maximum torque at 60.

If the AC drive output frequency is reduced from 120 Hz to 90 Hz at a con-stant voltage, the volts-per-Hertz ratio improves from 3.83 to 5.1 V/Hz. This is the same as providing 66 percent voltage at 60 Hz to a line-started motor. Torque will be 0.662, or 44 percent of the full voltage torque at 60 Hz. Figure 15 illus-trates the peak torque curve for constant

voltage operation from base speed to four times base speed.

Since the voltage, in reality, is not changing above base speed, it is more appropriate to define torque in terms of frequency change instead of voltage change. It can be stated then that torque above base speed drops as the square of the frequency; i.e.: doubling the frequen-cy quarters the available torque. Applied frequency and synchronous speed are equivalent; going one step further, torque may be defined in terms of speed. So in the constant voltage range, motor torque drops off as the inverse of synchronous speed squared, or 1/N2. (Fig. 16).

Many machine applications are con-stant-horsepower in their load charac-teristics. As speed increases, the torque drops off as the inverse of speed, or 1/N. The torque drop-off is not as severe as the motor’s peak torque—1/N2. Figure 16 compares peak torque to rated torque.

How does one determine the center of a worm and a worm wheel?

QUESTION #1

Worm Gears

First response provided by Joe Mihelick, Gear Technology Technical Editor:The center of the single enveloping worm is straightforward, as it is at a plane passing through the axis of the worm at its outside diameter. The cen-ter of a double enveloping worm gear is a bit more involved. It is nominal-ly located at a plane passing through the worm gear at its root diameter. If the worm gear is throated, the loca-tion of the minimum diameter of the throat will locate the nominal center of the worm gear. This is more useful for the manufacturing process but is less important in the successful operation or the worm – worm gear pair. The successful operation of worm gear-ing involves the actual contact pattern between them. The observed contact

pattern is to be from the nominal cen-ter of the worm gear towards the leav-ing side of the worm gear as deter-mined by the direction of the worm rotation.

Second response provided by Charles D. Schultz, PE, Chief Engineer for Beyta Gear Service, and Gear Technology Technical Editor ([email protected]):Short answer: It depends upon who is asking and what the intended applica-tion is. If you are specifying an off-the-shelf solution, you can rapidly deter-mine the appropriate size from sup-plier catalogs. Commercially supplied worm gear speed reducers are avail-able in a wide range of sizes, ratios and assembly configurations — from both U.S.-based and off-shore companies.

Worm gearing is not as standardized as spur, heli-cal and bevel gearing. Several different ‘systems’ coexist in the marketplace, and each has its propo-nents. In the smaller gear-box sizes (less than 4-inch center distance), exterior and mounting dimensions have become ‘standard’ and users can easily interchange between brands. Larger units have no such com-monality, and users are well advised to carefully consid-er all factors of supply (ini-tial cost, availability, service factor and after-sales sup-port) before selecting a ven-dor. Published ratings can be based on AGMA, DIN, ISO or other methods, and

have generally been applied with few problems.

While each manufacturer will tout their particular tooth design as hav-ing performance advantages, the key factor in power capacity remains the physical size of the parts and the mechanical properties of the materi-als used to make them. Worm gears have some unique capabilities that can be used to good advantage in machin-ery design. They are the only gear sys-tem where gear ratio does not affect the outside diameter of the rotating parts; this means a machine can eas-ily be supplied with a wide range of ratios — say 5:1 to 70:1 — without a center distance change or multi-ple reductions. Another capabili-ty — self-locking — can be a boon or a bane, depending upon your goals. Understanding these aspects of worm gearing can be a lifelong project, but users should ask the suppliers about it before ordering.

The long answer: Many ‘systems’ have been developed for worm gear-ing over the past 100 years. Each of them has its proponents and, oddly enough in the normally polite world of gear engineering, opponents. If off-the-shelf components won’t work for your applications, you have to pick one of these competing systems and wade through the often confusing recom-mendations to develop your gear set. Custom-made tooling is expensive and takes critical lead time to obtain, so designers are encouraged to use exist-ing hobs and fly cutters. I recommend the design system found in Daryl Dudley’s Gear Handbook, along with the worm hob charts on Ash Gear and Supply’s web site. AGMA’s standards The study of worm gears has come a long way: 16th century

Worm Gear Generation and their Manufacturing ToolsThe question will be answered considering the different possibilities in profile form,

kind of mesh, and type of tools. Figure 1 contains the general nomenclature used to define the geometry parameters.

Worm gear drives can be separated in three categories:Case A. Crossed helical worm gear drivesCase B. Cylindrical worm gear drivesCase C. Double-enveloping worm gear drives

Cylindrical worm gear drives “B” are the most common form. Their tooth profiles of the worms depend on the manufacturing method. The different profile forms accord-ing to DIN 3975 are:ZI: Tooth profile in face section is an involute; manufactured, for example, by hobbing,

like a cylindrical pinion. The hob for the worm gear manufacturing is a “dupli-cate” of the worm (however serrated and considering clearance and backlash).

ZA: Profile is a trapezoid in an axial section; manufactured, for example, by turning.ZN: Profile is a trapezoid in a normal section; manufactured, for example, by turning

with cutting blade tilted to lead angle of worm.ZK: Profile with crowning. Tool is disk cutter with trapezoidal profile, which is tilted

to lead angle of worm. Profile crown generated depending on disk cutter diameter.ZH: Disk cutter with convex cutting edges, causing hollow flank profiles in axial

section on worm teeth. Disk cutter axis is par-allel to worm axis (not tilted like ZK).

A. Crossed helical worm gear drive. This is a spe-cial case of crossed helical gears, where the worm is a helical gear with one to six teeth, and the worm gear has a high number of teeth (e.g., above 30). The pitch elements of a crossed heli-cal worm and worm gear are cylinders (Fig. 2). Both members—worm and worm gear—are manufactured like helical gears, with stan-dard hobs, for example. The profile of both members is involute. The hobbing tool in Case A is not identical to

A gear handbook in my possession states: The ZI worm is identical to an involute helical gear whose tooth number is the number of worm threads. Equations of tooth surfaces of an involute helical gear are the same as for an involute worm. Knowing that a ZI hob cutter is identical to a ZI worm, I conclude that the mesh of the ZI worm and involute helical gear is identical to a cross involute helical gear mesh; and even identical to the hobbing process of an involute helical gear with a ZI hob cutter.I would like to know whether I am correct and what is their difference.

QUESTION #2

are the most reliable rating method for the independent designer.

If your requirement is for instru-ment gearing or plastic gearing, it is recommended that you work with a supplier of such parts or an experi-enced design engineer. Tooling costs can be very high, and the performance of prototype sets can vary depending upon manufacturing method. Molded plastic teeth do not have exactly the same topography as cut gears; veteran suppliers of plastic gearing understand the changes needed to make sample parts that will work reliably without skewing test results.

Worm gearing design is an itera-tive process which can be frustrating the first few times you work through it. Standard worm hobs may not con-verge on the solution you would prefer. Some suppliers can make worm gears using ‘fly tools’ — a custom single-point cutter that allows more flexibility in design than the standard hobs. The cutting process is, by necessity, much slower than hobbing, but for one-off or low-volume requirements it is often the best solution. Regardless of the tooling ultimately employed, custom worm gearing design requires compro-mises on center distance, face width and numbers of teeth/threads. More than any other gear type, ‘your results may vary’ is an appropriate disclaimer.


the worm. The two members have line contact, which appear instead as point or small contacting zones.

B. Cylindrical worm gear drives (single-throat worm gear drives). A typical worm gear drive; here the worm also has one to six teeth (starts), and the worm gear has a high number of teeth (e.g., 30 to 300). The pitch elements of a single-throated worm and worm gear are shown in Figure 3. The worm is manufactured on a lathe or with a disk milling cutter. The profile is not a generated involute but a straight line. The geometry of a cylindrical worm therefore is similar to an ACME screw. The worm gear is manufactured with a hob and the hob’s enveloping surface is identical to the mating worm. This enveloping surface generates the same involute profile on the worm teeth as seen in Case A. However, the tooth thickness of the hob is thicker by the desired backlash amount. The difference in the gear in Case A is the shape of the pitch element, which in Case B has a hyperbolic form known as “throat.” The throat is formed merely by plunging the hob cutter at the center of the face width. The two members have line contact that appears on the worm gear member like slim ellipses with a major ori-entation (if projected in an axial plane) parallel to the worm gear axis.

C. Double-enveloping worm gear drives (double-throated worm gear drives). These are special types of worm gear drives with a very high con-tact ratio and high torque transmission abilities. Again, here the worm has one to six teeth (starts) and the worm gear has a high number of teeth (e.g. 30 to 300). The pitch elements of worm gear and worm have a hyperbolic appearance which is why Case C is called “double-throated” (Fig. 4). The worm is manufactured on a lathe, where the cutting blade profile rotates around a center point while it moves along the face width. The distance between the cutting blade pitch point and the center of blade rotation is identical to the pitch radius of the worm gear. The profile is not a gener-ated involute, but in a straight line. The worm gear is manufactured with a hob that has the pitch diameter of the worm at the center of the throat and the same number of starts, unlike the number of worm teeth. Also, here the worm gear is cut (as in Case B) by plunging with the hob cutter at the cen-ter of the worm gear’s face width. The two members have line contact that appears even under light load, as with large elliptical zones—even in single angular positions.

It should be mentioned that in Case B, where the worm gear tool resem-bles the mating member within the flank surfaces, there remain several differences. The tool face is extended in order to machine sufficient top-root clearance, and the top-land corners to the flanks are rounded with the desired root fillet radius. The dedendum depth of the tool is equal to the addendum of the worm, plus an excess amount to prevent any cutting action at the worm gear top-lands.

The short answer to all conclusions the questioner has posed is “yes.”

Siemens and KukaANNOUNCE COOPERATION AT EMO 2013

Siemens Drive Technologies Division and Kuka Roboter GmbH have announced a comprehensive cooperation at EMO in Hannover. The central pillar of the cooperation is integra-tion of Kuka robots and Siemens CNC solutions for loading machine tools. “With this joint approach, the two companies are strengthening the fundamental idea of integrated produc-tion and can, for example, develop new markets by close inter-meshing of machine tool tasks and loading tasks,” says Manfred Gundel, CEO of Kuka Roboter GmbH.

“The CNC control from Siemens and the robot controls from Kuka are ideal for integrating robot and CNC technology. With this cooperation, we are deepening our many years of coopera-tion and together advancing intelligent automation solutions as outlined by the Industrie 4.0 project for the benefit of both partners and to expand business,” says Dr. Robert Neuhauser, CEO of Business Unit Motion Control Systems at Siemens.

Highly flexible and fully automated production today demands complete integration of robots into the production flow and into the automation environment. In this area, in par-ticular, applications for robots and machine tools are growing together steadily as a result of new requirements and techno-logical progress. Given these developments, Siemens and Kuka are strengthening their cooperation in automation and indus-trial robots. The aim is to be better able to serve industries with high automation requirements in loading and machin-ing. With the shared development, customers will have access to new products and solutions that are coordinated optimally over their entire life cycle, from design, to production simula-tion, to engineering and the production shop level. Moreover, in the long term, the two companies will be including aspects of robot automation in their activities as outlined in the Industrie 4.0 project.

With this close partnership, Siemens and Kuka can offer end customers integrated solutions with a high technological demand and level of maturity and position themselves still bet-ter on global markets. At the center of the joint development and the closely meshed marketing activities is seamless, oper-ator-friendly integration of the robot for loading the machine

tool. The companies will also develop scalable, integrated solu-tions for machining workpieces with robots, especially for light-weight construction. In this field, in particular, new materials such as composites require innovative machining concepts that the two companies will be intensively advancing as part of the cooperation.

Kuka will provide robot systems that make use of proven solutions in the field of CNC with Sinumerik from Siemens for integration with machine tools. The standard implementa-tion of the concept includes loading by a Kuka robot, which is integrated in Sinumerik. A scaled offer is also planned, ranging from a robot with additional CNC machining functionality to a robot as a pure CNC machining unit. Here, too, the aim is com-plete integration of the robot into the PLM processes. At EMO 2011, both partners have already presented the integration of the robot into the Sinumerik user interface as an application, for programming, teach-in, and diagnostics. The next step will now be the connection to CNC tasks.

SiemensAPPOINTS NEW CEOs FOR INDIA, SINGAPORE AND CHINA

Sunil Mathur has been appointed CEO of Siemens’ Regional Company in India. Currently the CFO of the Regional Company in India, he will succeed Armin Bruck. Mathur has held a variety of posi-tions at Siemens over the past 25 years. Bruck is moving from India to Singapore, where he has been appointed CEO of Siemens’ Regional Company in this coun-try. The current CEO of the Singapore Regional C o m p a n y , L o t h a r Herrmann, has been named to head Siemens China. He will succeed Mei-Wei Cheng, who is retiring on expiry of his contract.

Additionally, Siemens plans to realign regional organiza-tion and strengthen corporate units. The regional cluster setup which is currently in effect at Siemens is to be eliminated. By implementing this move, which will give the individual coun-tries more competences in the future, Siemens intends to intensify its customer access and expand its regional business. “Eliminating the clusters will make Siemens more streamlined and closer to the markets. We’re substantially strengthening our regions, whose heads are our customers’ most important con-tacts,” stated Joe Kaeser, president and CEO of Siemens AG.

The realignment will eliminate an organizational level at the company, and the various countries will be more closely geared to the business of the Sectors. In the future, the countries which are most important for Siemens – based on their business vol-ume and growth prospects – are to report directly to the four Managing Board members who are responsible for the Energy, Healthcare, Industry and Infrastructure & Cities Sectors. These so-called lead countries account for more than 85 percent of the company’s revenue, and smaller countries will report directly to them.

As part of the realignment of the regional organization, Managing Board responsibility for the various regions will also be reassigned. In the future, Energy CEO Michael Süß will be responsible for the NAFTA region and the Middle East; Healthcare CEO Hermann Requardt, for South America and Japan; Industry CEO Siegfried Russwurm, for Europe, Africa and the C.I.S.; and Infrastructure & Cities CEO Roland Busch, for Asia, excluding Japan, and Australia. The restructuring of the regional setup is aimed at enhancing local market penetration.

India, just like every country these days, has its economic worries and challenges. The fact remains, however, that the country has the third largest GDP in Asia — after China and Japan. According to report-linker.com, India’s “Economic growth hit a decade-low of 5.0 percent in 2012, but growth rates are expected to gradually pick up, reaching 5.5 percent in 2013 and 6.0 percent in 2014.”

A major part of daily life is healthcare and, relatedly, the medical device indus-try. According to several reports, that’s a niche that some foreign players are aggressively looking to fill. Reports also suggest, merely the continued growth in India’s population ensures a waiting market and fertile ground for R&D and manufacturing. And that development has not gone unnoticed by others.

Fiercemedicaldevices.com reports that New Delhi’s Medtec India show, accord-ing to Plastics News, “provides a good gauge” for determining who those “oth-ers” may be.

While most medical devices are still imported, there are definitely companies looking to get an early step up on what many feel will be a steadily growing—and competitive—market. For instance: USA-based SMC Ltd. launched a manu-facturing facility in Bangalore in 2011 and is planning to make plastic medical devices there for cardiovascular, respira-tory and orthopedic use; the Swiss com-pany, Mikron, a maker of high-precision assembly and testing equipment, is look-ing to set up shop in both China and India; and FLG Automation, a German company, is intending to manufacture dialysis and filter-technology compo-nents in India.

The reasonable consensus among ana-lysts is that India’s burgeoning popula-tion growth is spurring government to modernize the country’s healthcare sys-tem — including the regulation of medi-cal devices.

While the private sector remains India’s primary care provider, there is a growing need of high-quality, high-tech medical equipment to serve those not in a private health plan — and that is a high number. Reports indicate that health insurance coverage remains low, with private health insurance covering less than 5.0 percent of private health spending, and only around 3.2 percent of total health expenditure. Since 2008, the government has funded a program to provide health insurance coverage for the very poor, which currently covers around 32 million families.

SMC, the American device maker, considered this an opportunity for growth in India when it opened its man-ufacturing facility in 2011.

And in a December 2012 Plastics News (ITAL) story reported by Satnam Singh, “We are planning to manufacture plastic medical devices for cardiovascu-lar, respiratory and orthopedic systems in India and we have started produc-ing a couple of devices for cardiovas-cular systems in our Bangalore plant,” said company spokesman B. Balakrishna Menon. Interestingly, SMC also plans selling into the U.S. and Europe from its Bangalore plant. According to Menon, the plant’s capabilities include device and tool design, prototyping, tool-making, component molding, sub-assemblies and finished devices.

And at Mikron, “Earlier, we were focus-ing more on the European markets, but now focus is on India and China, as both are growing markets,” said Mikron Automation regional sales manager Harald Herrmann. “Potential is there in India, but the degree of automation is low.”

As for FLG, it is more of a wait-and-see stance: “We have not sold any equip-ment to India as yet; we are studying the market,” said Thomas Simon, sales man-ager for FLG medical technology.

And there are other skeptics who believe it is too soon to jump into the fray.

Pawan Urs M., a regional sales man-ager for quick-disconnect maker Colder Products Co. of St. Paul, Minnesota, believes the market in India is certainly growing — but, for now, at too slow a pace.

“The Indian medical device market is growing slowly and is in a nascent stage, not comparable to China,” he said. “The high-tech medical devices are largely imported in India. We see lot of poten-tial in this market, but it still has long way to go.”

And yet a recent report by visiongain.com, a London-based business analyst, predicts that the Indian medical device market will reach $11 billion by 2023. Last year, the Indian medical device market generated $3 billion in sales.

Rupali Vadhera, a healthcare industry analyst, credits the growth to the govern-ment for expanding healthcare coverage to rural areas and to the growth in the private hospital sector.

“The Indian medical device indus-try has experienced tremendous growth in recent years, as a result of increased awareness amongst the end-users, and affordability of healthcare prod-ucts and services with the increas-ing spending power. The availabili-ty and easier access to healthcare has increased the use of medical devices.” (Sources for this article: reportlinker.com; Fiercemedicaldevices.com; Plastics News; and visiongain.com.)
