P U B L I S H E R ’ S P A G E

This marks the final issue of our first year of publication of Gear Technology India. As such, it’s an appropriate time to reflect on all we’ve accomplished, as well as to look for-ward to all of the accomplishments we hope to achieve in 2013 and the coming years.

By almost any measure, the first year of Gear Technology India has been a resounding success. We have heard noth-ing but positive comments from our readers and advertisers about how this magazine fills a void in the Indian market-place. We are proud to have brought this magazine to life and provided this valuable service to the industry.

A large part of the service we provide is to be the indus-try’s meeting place, not only for the exchange of ideas and technical information, but also as a mechanism to facilitate trade. Connecting buyers and sellers in our industry is a big part of our mission; that’s why we feature product news prominently every issue. It’s why we include profiles of industry suppliers.

It’s also why, with this issue of Gear Technology India, we present our first ever Gear Industry and Power Transmission Components Buyers Guide. The Buyers Guide represents many months of work gathering informa-tion and compiling results.

Our Buyers Guide is divided into two main parts:Section 1 deals with machine tools, tooling and servic-

es—specifically those used to manufacture gears. If your company manufactures gears, splines, sprockets or similar components, then you’ll find suppliers of all the equipment and services you need in this section.

Section 2 focuses on mechanical power transmission com-ponents. Those of you who are involved with buying, speci-fying or recommending components like gears, bearings, motors, belts, clutches and couplings can look to our Buyers Guide for a comprehensive selection of suppliers, listed by product category.

Just as our first year of publication was only the first step in a long journey, so too is this printed buyers guide only the beginning. Starting next year, we’ll be launching the online version of our Buyers Guide at www.geartechnologyindia.com. In the online version, you’ll have access to even more comprehensive listings of suppliers and their products and services. In addition, we’ll keep the online version continual-ly updated with the latest information, and those companies that have not yet been listed will get a chance to do so.

We’d like to thank everyone who has helped make our first year a success. Of course, that begins with you, the readers. Without you, there would be no need for what we do. We would also like to thank all of our advertisers, whose support allows us to continue with confidence into next year and beyond.

Finally, I’d like to thank all of our friends and partners at Virgo Publications, whose tireless efforts to promote the magazine to potential readers and advertisers are a large part of our success.

Even though the first year is complete, what we’ve done so far is just build a foundation for the future. In fact, we’re already hard at work planning and preparing for the first issues of 2013. We have much in store for you next year, and we’re excited to have you continue this journey with us.

Michael Goldstein,

Publisher & Editor-in-Chief

Romax TechnologyLAuNCHES GEARbOx AND DRIvELINE DESIGN SOfTWARE PACkAGE

Romax Technology, a gearbox, bearing and driveline engineering specialist, has launched a new design software package that will increase speed, quality, creativity and innovation when designing gearboxes and drivelines. Called Concept, the new product delivers on the Romax vision of streamlining the end-to-end, planning-to-manufacture pro-cess with open, easy to use software solutions. It has been developed in close collaboration with engineers in the largest ground vehicle, wind energy and industrial equipment com-panies around the globe.

The result is a highly intuitive drag-and-drop design envi-ronment enabling rapid creation of concept models. It pro-vides semi-automated sizing, definition and rating of gears, shafts and bearings, with advanced 3-D visualization capa-bility allowing evaluation and manipulation of key param-eters. As a result it promotes creativity as new design ideas can be evaluated rapidly.

Concept also utilizes Romax’s analytical capabilities to enable initial NVH assessments, as well as preliminary mechanical design assessments of alternative concepts.

It is applicable for any gear, shaft and bearing system application, from power tools to mining equipment and from complex automotive planetary automatic transmissions to the largest wind turbine gearboxes. The new software not only enables creativity, effectiveness and efficiency, it also promotes a seamless workflow either as a stand-alone solu-tion or used in conjunction with other CAD packages.

Its innovative, easy-to-learn interface allows new users to become productive extremely quickly, which means gradu-ate designers through to experienced gearbox and drive-line design teams can use it. Romax Technology Product

Manager, Dr. Jamie Pears, who is heading up the product launch, believes concept design is one of the most important aspects of the gearbox and driveline product development process.

“Early decisions can be crucial in shaping product per-formance, robustness and durability, as well as minimizing manufacturing and operating costs,” he said. “However, this stage of development can be expensive and time consuming too, meaning that many engineered products fail to reach their full potential. This next generation design package, which incorporates many of our advanced analytical algo-rithms, helps users to pull forward new concepts into robust and highly optimized designs capable of subsequent detailed development. It not only saves development time and cost but also improves the quality and robustness of the finished product.”

Also supporting Romax’s vision of streamlining end-to-end, planning-to-manufacture process is significant new capability in the company’s flagship products for detailed design and analysis—RomaxDesigner and RomaxWIND. This enhanced capability for improved manufacturability of end-product includes a comprehensive suite of tools that enables the gear manufacturing process to be considered as part of the gear design and analysis activities. Romax announced Concept in October and will be shipping the soft-ware in December.

Grind MasterDEvELOPS GEAR fINISHING MACHINES

Grind Master has developed a gear deburring machine which can be used for deburring large gears. Gears with a minimum diameter of 200 mm to maximum diameter of 2,000 mm (2 meters.) and maximum weight of 4,000 kg and module 4 mm to 24 mm can be deburred with this machine. Features include a six degree of freedom to deburring head and one degree of freedom to gear which ensures deburring of spur, helical and spiral bevel gears. Also, the machine is supplied with removable brushing heads.

Additionally, Grind Master offers a new automatic gear tooth chamfering and deburring machine for deburring spur, helical, bevel gears, sprockets, crown wheel gears, etc. This new concept machine uses carbide cutters for chamfer-ing and deburring. A high-power brushing unit is used for removing secondary burrs and for achieving a smooth edge on the gear tooth profile. The machine produces a very uniform looking chamfer and it does not require in-process adjustments. The biggest advantage of this new model is low running cost.

Grind Master also offers an automatic machine for deburr-ing both edges of a tooth simultaneously with two deburring heads. Crown wheels or gears up to 450 mm diameter and module 1 to 10 mm can be deburred. The job rotation speed can be varied from 1 to 6 rpm by an A.C. speed variator. The job axis can be swiveled up to 20 degrees to obtain uniform chamfer quality. The deburring heads have all round easy adjustments to take all types and sizes of gears. Grind Master also builds special machines for deburring gears up to 2 m in diameter and one ton in weight. Options include a complete machine enclosure and dust extraction system.

KISSsoftADDS SOfTWARE IMPROvEMENTS

Gear contact analysis has been improved in KISSsoft soft-ware. Increasing the power density of gearboxes requires gear sets to feature profile and lead corrections. The influ-ence of these corrections, combined with the deflection of the shafts, bearings and the housing can now be studied in great detail using the “Tooth contact analysis.” Said analysis has been improved in KISSsoft version 03-2012 to include the KHβ calculation according to ISO6336-1, Annex E, as

well as detailed micropitting, flash temperature and EHD oil film thickness calculation according to ISO/TR15144. Fourier analysis has been added for the transmission error calculation so that the spectral content of the meshing vibra-tion may be analyzed. This will further help the designer to select suitable profile and lead corrections. KISSsoft software is used by about 100 companies in India, and it is developed by a group of eighteen mechanical engineers and mathemati-cians in Switzerland. The latest release, version 03-2012, also showed new functions for the design of spiral bevel and hypoid gears as well as with respect to accurate 3-D geom-etry calculation of non-standard gears. This allows for direct machining of large worm or spiral bevel gears, which is of major interest for repair works, prototyping or small series production in case specific gear cutting machines are not available.

Additionally, KISSsoft now creates accurate 3-D worm gear geometry. Direct machining of worm wheels is of inter-est in case that only few units should be produced or specific worm gear cutting or tools are not available. This may be relevant if worm gears to be cut are of large size or if lead times for tools are too long. KISSsoft software now provides a solution to this problem as it allows for the fully accurate 3-D modeling of worm wheels of ZC, ZI, ZA, ZK, ZN and ZH type. The geometry may be exported as step or parasolid

file, allowing for the import into a CAM software for pro-gramming of the machining with e.g. a 5-axis CNC milling machine. Besides worm and worm gear geometry, spiral bevel gears and cylindrical helical gears may be generated for direct machining.

ning unit and electronics of the HOG 86 do not come in contact with dust or humidity when the terminal box is opened during the installation or wiring process.

The bearings of the new hollow shaft encoders are protected from damages caused by inductive shaft currents. The HOG 86 is also available in a durable hybrid bearing version. This enables the encoder to achieve an exception-

ally long service life of up to 100,000 hours, while still being reliable at oper-ating temperatures between -40 and +100 degrees. Installation flexibility and simplicity are added advantages of the HOG 86. A terminal box that can be rotated 180 degrees and various installation options make the encoder very easy to install.

With the HOG 86, Baumer has also combined precise measurements with

additional safety. The optionally avail-able integrated Enhanced Monitoring System (EMS) continuously monitors all encoder functions across the entire speed range. If an error occurs, the sys-tem triggers warning messages that are displayed right on the device itself. This speeds up the troubleshooting pro-cess, which in turn helps everything get up and running again quickly and safely and prevents costly downtimes.

MaxonPLAYS ROLE ON MARS ROvER

The landing of the Mars rover Curiosity took seven exciting minutes. Now it is looking for signs of life on the Red Planet. Maxon encoder tech-nology played a part in the successful excursion of the rover. This is the con-tinuation of the success story of Maxon products in outer space and on faraway planets. The new Mars rover Curiosity ended its six-month-long journey to Mars with a successful landing on


P R O D U C T N E W S P R O D U C T N E W SAugust 6th 2012. As everything went according to plan, the control center at Jet Propulsion Laboratory (JPL; California) erupted in cheers. “It was a wonderful landing, everything looked extremely good,” said Adam Steltzner, NASA engineer and lead scientist of the JPL landing team, enthusiastical-ly at a press conference. This is the start of a new, exciting excursion on the Red Planet. In contrast to the rov-ers Opportunity and Spirit, Curiosity can travel further distances on its six wheels and run longer without solar energy as a radionuclide battery gives energy for years. The plan is that the rover shall explore the immense Gale Crater on Mars for signs of life, for two years. And this with impressive equip-ment on board—a gas chromatograph will hopefully uncover organic com-pounds; a spectrometer will analyze the composition of rocks which will be collected by the two-meter-long robot arm and a neutron source will look for hydrogen in the ground.

The MR Encoder technology from Maxon is built in to the electrome-chanic joints of the rover. The mag-netic sensors are mounted on the drive shafts and are responsible for con-trolling the motors. Apart from that, Maxon development services for the drive systems have also played a part in the 900 kilogram rover being able to carry out its Mars mission successfully.

Curiosity’s little brother Opportunity is still on its journey on Mars; for the past eight years, the rover has been exploring Mars with the help of Maxon Motors. A further success for Maxon is the SpaceX mission to the International Space Station (ISS). Amongst other things, brushless EC motors have been used to move the 2 solar panels which always have to be facing the sun in order to supply the Dragon Capsule

with power. More flights to the ISS are already planned; the next in September 2012. In 2015 a further rover will be sent explore Mars for the Exomars Mission. The moon is also in sight—at least for the Chinese Lunar Exploration Program (CLEP) when an explora-tion rover will be sent to the moon. Numerous research satellites nearer to Earth will also be fitted with Maxon drives. The next start of such a satellite

Amacoil/UhingANNOuNCE fLANGE DETECTION SYSTEM

Amacoil/Uhing has announced that their FA Flange Detection System has been reengineered for simpler opera-tion and now utilizes laser sensor tech-nology for expanded functionality. The new FA-II system is PLC-controlled and requires none of the tedious adjust-ments associated with the previous ver-sion. Additionally, whereas the original system worked only on spools having straight flanges, the new FA-II may be used with spools having either straight or tapered flanges. The FA-II system saves time by eliminating the need for an operator to adjust the reversal stops on the Uhing traverse. During spool changeovers, it is often the case that a new spool is not placed on the mandrel in the exact same position as the spool being replaced. Normally this means that a worker must readjust the end stops on the traverse to make sure the traverse reverses at the correct points. The FA-II eliminates this step, saving time and enabling operators to manage more winding stations, which helps boost production. Furthermore, wind-ing accuracy is improved because the laser sensor is a more accurate means of locating the spool flange edge than the human eye.

In its original version, the FA fea-tured a two-pronged fork-shaped fix-ture mounted on the Uhing traverse. A steady beam of light between the prongs formed a light curtain, which,

is the ESA Sentinel 3, which will fly into space in 2013. Here Maxon motors will be used, for example, in a possible emergency to control and secure the fuel valves.

P R O D U C T N E W Swhen interrupted by the flange edge, triggered pneumatically controlled reversal of the traverse. Instead of a light beam, the FA-II system employs a laser sensor mounted to the traverse. The sensor continually references the distance from the spool core up to the highest point that wire or other mate-rial will be spooled. When the sensor detects the spool flange, the reading is not within the acceptable variance and a signal is sent to a pneumatic cylinder which reverses the traverse.

This arrangement also enables FA-II use with both straight and tapered flanges, thereby expanding the sys-tem’s application. Because the distance from the sensor to the sloping surface of the tapered flange is less than the master reference point, reversal is not triggered until the spool flange edge is detected.

To optimize the effectiveness of the FA-II Flange Detection System, it is necessary that spool flanges are not bent or damaged. The laser sen-

sor should be protected from partic-ulate contaminants (dust, metal par-ticles, wood chips, etc.). The FA-II system accommodates materials with round cross-sections and a diameter of 0.1 to 2.0 mm (.004 - .079 in.). Spool flange diameter may be up to 220 mm (8 43⁄64 in.) maximum. The system will handle spools with tapered flanges having an angle of up to 40 degrees. Operating temperature range is -10 to 40 degrees C (14-104 degrees F). Maximum operating air pressure is 6 bar (87 psi).

Gears have been manufactured for hun-dreds of years—since humans have had the need to transfer one form of mechanical energy to another. Gear making is a science that evolved over those years. Much of gear-

ing’s historic develop-ment and nomenclature

is rooted in the technolo-gy of the time. Computer technology is a newcomer that has greatly impacted industry in only the last 30 years.

The classic gearing gage lab once consisted of several machines/instru-ments that could test gears in both functional and dimensional analyti-cal terms. The modern gear measuring machine, by contrast, is a highly dis-crete and accurate digitizer that feeds only raw coordinates to a computer. The computer operator must convert that data so that it relates to the func-tion and manufacturing techniques used in making the component.

It should be no surprise that the clas-sic gear lab addressed those needs. The instruments found there were the best that the technology of the time could deliver, so that gears of high quality (for the time period in question) could be manufactured. Classic gear inspec-tion consisted of several sophisticat-ed machine/instruments that involved some complex mechanisms that simu-lated the manufacturing process and functional needs of the end-result gear.

Involute ProfileIn almost all medieval castle movies

we see huge gears made with round wooden pegs that draw up the bridge over the moat. In reality almost all of today’s gearing is based on involute tooth profile as opposed to round or circular profiles. An involute profile resembles an arc at first glance, but it is a shape defined by mathematics. It is a

shape that would be defined by the end of a string that is held taught while it is unwrapped around a cylinder. The cyl-inder is called the base diameter and it defines a unique path for the end of the string. The string forms a tangent to the cylinder. The angle of that tangent line is called the roll angle. The roll angle is zero where the end of the string crashes into the cylinder.

Involute profile gears have the major advantage of two perfect gears mesh-ing together with continuous points-of-contact on opposing teeth. So no change of speed and an even load of energy transfer between the two rota-tional axes occur. In theory this is true, but the shape is generally crowned or modified because the gears will deflect under load or have been modified to reduce noise and increase efficiency.

The pitch diameter is the place where the work is being done. Usually it is right smack in the center of the gear tooth and is the effective diameter of a gearset when computing the gear ratio or reduction.

An involute checker is a device that turned the gear as a function of the roll angle while through a complex set of cams and mechanical settings, which moved an indicator along the nominal,

involute profile. A chart recorder then recorded the output of the indicator as a function of the roll angle. This chart was then the basis and reference for modifications. Terms such as K-chart and X-chart were tolerance zones and nominal shapes that overlaid the chart recording (Fig. 1).

This was obviously a time-consum-ing and tedious testing process since the roll angle and involute cams and levers needed to be synchronized together, along with a null point of the indicator. Rarely would an entire gear (every tooth) be tested for profile. Since teeth are generally generated in a repetitive cutting process, a small sam-ple of teeth was considered adequate. In most standardized reporting formats today, four teeth evenly spaced is con-sidered adequate profile testing.

With current scanning technology, involute testing is a simple cross-sec-tional scan across the face of the tooth in a plane perpendicular to the gear’s rotational axis. A simple spur gear can be adequately accessed by a standard three-linear-axis CMM. Helical gears, on the other hand, present an access problem that requires either a complex stylus cluster or a rotary table that is

the main feature of a dedicated gear-measuring center.

That is why the dedicated machines for gear metrology have been devel-oped; the evaluation and reporting was modeled around those instruments. Instead of classical coordinate curve representations, the output was bent to simulate the strip chart recording of the original involute profile tester.

Simulated gear-measuring machine output of an involute profile tester dis-plays four teeth, equally spaced about the gear. The vertical axis is the radial distance to the center axis and the hori-zontal axis is the deviation from the nominal involute.

Gear Lead TestA lead tester was an instrument that

added a significant third dimension to the testing. The Z-axis along the axis of rotation was, through belts and gears, actuated in a manner that related Z position to roll angle. Like the invo-lute test, the indicator now moved in a nominal helix and the strip chart output was deviation from that helix (Fig. 2).

Just like the involute profiles, the lead strip chart was just the starting point of the evaluation and modifica-tion of those shapes, usually crowns, were superimposed on that chart. The vertical axis is the Z-axis position and the horizontal axis is the indicator movement or deviation from a nominal helix.

Tooth Spacing TestingThe involute and lead testers were

instruments that were developed to simply check the shape of tooth form; no information is obtained from them as to the position or location of the tooth. A variety of different types of instruments and methods were employed to determine the tooth loca-tion.

Today the gear measuring machine can be programmed to probe each tooth face on the pitch diameter (Fig. 3).

Gear Metrology

Figure 2—A lead test plots a gear’s deviation from its nominal helix.

Figure 3—Today the gear measuring machine can be programmed to probe each tooth face on the pitch diameter to provide accurate tooth spacing measurements and pitch errors.


Tooth thickness is a critical feature of the manufacturing process and per-formance of the gear.

Likewise it required special tech-niques, fixtures and equipment to mea-sure the tooth thickness in the classic gear lab. For gear measuring methodol-ogy, the spacing data obtained above was derived from the coordinate loca-tion of the teeth at the pitch diameter. That data, when analyzed differently, contains the thickness information.

In effect the gear measuring center has that data for free and requires just the evaluation and reporting.

Roll Tester (Run-Out Testing)One of the most critical and neces-

sary tools in the classic gear lab was a roll tester. Unlike the other instruments that attempted to measure dimensions or specific material conditions on a gear, the roll tester combined this metrology with functional testing.

One spindle was on a movable axis and a pre-load was applied between the gears. If the test gear had poor dimen-sional quality, then the net effect would be some relative motion between the two spindles, which were monitored again with a strip chart recorder.

Obviously this was not as discrete and analytical in terms of determin-ing where the problem lies, but it was a relatively fast overall check of the quality of the gear. The frequency and magnitude of that motion would give an expert a hint as to where the dimensional problem might lie. And that would begin the search using the other more dimensionally specific test-ing methods.

There are, however, hidden costs and problems with roll testers. The larg-est problem is with the master gears, which have to be precisely manufac-tured, and their uncertainties recorded (Fig. 4). Any errors are directly super-imposed on the roll test data. The gear measuring center, in contrast, has the raw data stored already and requires the actual data for analysis and report-ing tools to isolate this functional char-acteristic of the gear.

What If?Gears are workpieces where the

metrology and error sources have com-plex interactions with net performance. The classic gear lab attempted to make a variety of tests that were feasible to that time period to qualify gears.

Computers now allow a much more raw unfiltered basic set of coordinates to be massaged and processed with the same results.

What if we removed the run-out of a gear? How would the tooth spacing look?

In a previous gear tooth spacing report we have a spacing chart with 85 µm variation. If we remove the run-out component, then the spacing is only 29 µm as shown (Fig. 5). One metrologi-cal variable can make another appear far different than it really is.

Figure 5—By using the modern gear measuring center, we have access to multiple sets of data. For example, we can determine how much of tooth spacing error is due to run-out and how much is due to other factors. In the above example, if we remove the run-out component, then the tooth spacing error is only 29 µm, as opposed to 85 µm with the run-out included.

Figure 4—A modern analytical gear inspection system can provide complete run-out information, which used to require roll testing.

Got a Gear Question?Ask the Expert!

A S K T H E E X P E R T

Dear David,

AGMA 913–A98—Method for Specifying the Geometry of Spur and Helical Gears—gives all the equations you need for calculating profile shift.

The reference pressure angle measured on the generating pitch diameter (the same as the standard pitch diameter or reference pitch diameter) is determined by the cutter pressure angle and is usually 20° for most gears. It is independent of profile shift. The operating pressure angle is determined by the operating center distance of the mating gears and is again independent of the profile shift.

You can think of profile shift as simply shifting the teeth outward or inward so that the active profile of the teeth uses a different sector of the same involute curve.

Profile shift does not require special cutters if straight-sided hobs are used (the usual case). The hob is simply shifted outward or inward to shift the profiles, and the outer diameters of the gears are changed to accommodate the pro-file shifts. Therefore, the advantages of profile shifting are achieved with no cost consequences. Only form cutting such as milling requires a different cutter for profile shifted gears. That’s because form-cutting or form-grinding require a cutter or grinding wheel with a profile that matches the shape of the tooth space. Since profile shifting changes the shape of the tooth space, the shape of the form cutter must change.

One of the most important parameters in any gear design is the number of teeth in the pinion, and profile shift has its greatest relevance when the pinion has a small number of teeth. In fact, the first use of profile shift was to avoid under-cut in pinions with less than 17 teeth. It was later realized that profile shift improves most aspects of gear operation, and today it is used for many reasons including:• Avoiding undercut• Avoiding narrow top-lands to avoid case/core separation in

carburized gears• Balancing specific sliding to maximize wear resistance and

Hertzian fatigue resistance• Balancing flash temperature to maximize scuffing resis-

tance• Balancing bending fatigue life to maximize bending

fatigue resistance

Gears with few teeth are more sensitive to profile shift, and their tooth shape changes more dramatically, whereas profile shift changes tooth shape only slightly for gears with a lot of teeth. In fact, the teeth of a rack (with theoretically infinite number of teeth) do not change shape as the teeth are profile shifted. These effects can be seen in Figure 4 of AGMA 918–A98. It’s best to design gear sets with pinions with at least 20 teeth—and preferably 25—in which case the

Profile ShiftRegarding profile shift: What kind of data must be considered when we grind a gear

with shift profile?A few days ago we received a series of gears that need to be corrected (profile shift).

Our engineering department had a question about this topic; they tell me that they do not know how to calculate the gears with profile shift and that they have big doubts over whether—with each profile shift factor—the pressure angle also changes.

A friend in Texas told me that you cannot make a profile shift gear with a cutter in a traditional way. For each correction factor, you require a cutter according to the modification. Is this is correct?

profile shifts for balanced specific sliding, balanced flash temperature and balanced bending fatigue life are all nearly the same.

See AGMA 901–A92—A Rational Procedure for the Preliminary Design of Minimum-Volume Gears—for a method to design gears with maximum-load capacity by bal-ancing the macropitting resistance and the bending fatigue resistance.

Figures 1 and 2 demonstrate how profile shift dramatically improves specific sliding. Figure 1 shows the specific sliding for a gear set with no profile shift. Figure 2 shows the same gear set after the pinion and gear have profile shifts designed to balance and minimize the specific sliding. Profile shifting has greatly reduced the specific sliding from -4.03 to -1.28. This improves the meshing characteristics of the gear set by reducing the frictional loss, lowering the contact temperature and increasing the resistance to wear, macropitting, micropit-ting and scuffing.

Dear David,Profile shift—sometimes known as ‘addendum modifica-

tion’ or ‘correction’—is the displacement of the basic rack (or cutting tool) datum line from the reference diameter of the gear. The size of the profile shift (mm or inches) is usual-ly made to be non-dimensional by dividing it by the normal module (or multiplying by the DP), and it is then defined by the profile shift coefficient ‘x’. A positive profile shift increases the tooth thickness while a negative profile shift reduces tooth thickness (this applies to internal and external gears alike). This is illustrated in Figure 1, which is copied from ISO 21771:2007, i.e., Gears: Cylindrical Involute Gears and Gear Pairs—Concepts and Geometry.

The only difference in machine setup required for cut-ting profile shifted gears is to change the radial position of the cutting tool by an amount defined by the profile shift. The cutting tool module or DP, cutting tool pressure angle and number of teeth on change gears on manual machines, remain unchanged. This in turn means the base diameter (and base helix angle on helical gears) remain the same. A key benefit from using involute gears is that we don’t need to change the cutting tool to make gears with a different diameter and tooth thickness.

Profile shift is used by designers for many reasons includ-ing the elimination of undercut when hobbing or shaping gears with few teeth, minimizing sliding at the gear pair start of active profile, increasing bending strength, increasing or decreasing the center distance and changing tooth thickness

or backlash. In fact all gears have some profile shift when you consider that we normally move the cutting tool radially to change the tooth thickness.

A common perception is that profile shift changes the ‘pressure angle’ of a gear.

This is wrong.The pressure angle we specify on the drawing is the pres-

sure angle of the cutting tool. The actual gear flank pressure angle changes from root to tip and the working pressure angle (the angle of the line of contact) of a gear pair depends on gear center distance and gear base diameters only. If

the sum of the pinion and wheel profile shift is zero, the gears operate at the reference center distance. If this sum is negative the gears have smaller center distance and thus they have a smaller operating pressure angle, while a posi-tive sum requires a larger center distance increased operating pressure angle.

For further information on this subject I recommend a document published by British Standard PD 6457—Addendum Modification to Involute Spur and Helical Gears, and also ISO 21771:2007, published by ISO. These refer-ences contain the calculations and recommendations for minimum profile shift to avoid undercutting and maximum profile shift that can be applied before the tooth crest thick-ness become too thin. Most commercial software packages provide options for specifying profile shift; the effects can be demonstrated graphically and improvements in gear perfor-mance can be quantified, as seen in Figure 2.

Rob is also actively involved with delivering the British Gear Association (BGA) training semi-nar program and is an active member of the AGMA Gear Accuracy and Calibration committees.

Dear David,Profile shift, also known as x factor, is just a method for

specifying tooth thickness. If the gear drawing has a “mea-surement over pins” or “span over a given number of teeth” or other tooth thickness specification that you are familiar with, you can just grind the gear to meet the specified tooth thickness and safely ignore the profile shift.

Many of those familiar with profile shift find it very easy to use during the design of a gear pair. However, the result-ing gear is not fundamentally different from one designed by other methods. Cutters do not need to be modified to create gears with different amounts of profile shift.

The concept of profile shift is quite simple: as a gear cutter is shifted radially towards the center of an external gear, the tooth profile will of course also be shifted towards the gear center. At a given diameter, such a shift of the tooth profile results in the teeth appearing thinner. Since the actual pres-sure angle varies with diameter, a shift in the profile changes the pressure angle at a given diameter. But this change in pressure angle does not mean there was a change in tooling; it is the natural result of sinking a given tool deeper into the part.

The symbol for profile shift is x, and it is a coefficient; i.e., it is normalized so it is non-dimensional. The sign conven-tion for profile shift is that a positive profile shift results in thicker teeth. So shifting a cutter towards the center of an


www.geartechnology.com August 2012 GEARTECHNOLOGY 49

external gear is a negative profile shift, since it makes the teeth thinner.

The profile shift usually used by gear designers is for a zero backlash gearset. To provide some backlash, some designers increase center distance while others reduce the profile shift. When you subtract an additional small shift as a backlash allowance from the non-dimensional zero backlash profile shift, and multiply by module to get millimeters, the result is called the “rack shift.”

In Europe, some gear designers specify only the zero backlash profile shift and the manufacturer will thin the teeth according to tables in the DIN standards. If you receive such a drawing that does not specify an actual measurement of the finished gear teeth, then you should discuss with your cus-tomer what is actually expected.

For more information, see AGMA 913–A98. This informa-tion sheet was written to introduce profile shift to engineers in the United States. There are also many computer pro-grams, such as AGMA’s Gear Rating Suite, that will allow you to easily convert from profile shift to other forms of tooth thickness specification.

Management SummarySince the late 1990s, the Timken

Company has employed surface engi-neering technologies on bearing rollers to provide wear resistance and friction reduction to demanding customer ap-plications. More than a decade of in-tensive research and development has resulted in two new technologies that, when used in combination, expand the performance of rolling element bearings well beyond previous limits.

Timken’s new surface engineering technologies were not developed to be temporary fixes, but were instead de-signed to address the root causes of the mechanisms responsible for life-limiting bearing wear. When rolling elements with these surface engineer-ing technologies are incorporated into roller bearings, the bearing assembly is referred to as a Timken wear-resistant bearing.

Surface engineering. Surface engi-neering is the practice of altering the chemical and/or topographical proper-

ties of the surface of a component or device. Timken has previously shown that an engineered surface, which has worked well at reducing wear in rolling element bearings, is a metal-containing diamond-like carbon coating applied to super-finished rolling elements (Refs. 1–2). It is sometimes beneficial to con-sider real surfaces as having roughness on different length scales. So, whereas, quantities—such as Ra and Rq—de-scribe longer length roughness char-acteristics, shorter length roughness is better quantified by a quantity such as asperity slope Dq.

A standard finish on a rolling el-ement—typically one that has been ground and honed— produces a surface with a long-length scale roughness that in cross-section resembles the illustra-tion labeled as “Standard” (Fig. 1). Ra and Rq values of 100 nm and 140 nm, respectively, are commonly measured on these surfaces. An illustration of a sur-face produced by a super-finishing pro-cess is also shown (Fig. 1).

These surfaces have typical Ra and Rq values of 60 nm and 90 nm, respective-ly. Surfaces with smaller Ra and Rq val-ues promote greater separation of con-tacting surfaces and larger load-bearing capabilities that produce a more desir-able distribution of contact stresses in the material than surfaces produced by standard finishing processes.

Analysis of the short-length scale roughness from measurements of ground, ground + honed, and super-finished surfaces yields average asper-ity slopes (Fig. 1). Because asperity in-teractions in contacting surfaces play an important role in wear modes—micro-pitting and smearing, for example—the smaller the asperity slope, the smaller the interaction.

A super-finishing process described by Hashimoto, et al. (Ref. 3) can pro-duce surfaces such as that shown (Fig. 2), in which most of the traditional ma-chining features have been removed. For comparison purposes, a standard surface that has been ground and honed is also shown. 3-D topographical profiles of each surface obtained by a white light interferometer microscope are shown below the optical images.

Super-finished surfaces are especial-ly beneficial to mechanical components operating in boundary layer lubrication because the opportunities for asper-ity interactions in the contact areas are greatly reduced.

Metal-containing, diamond-like car-bon (DLC) coatings were first devel-oped by Dimigen (Ref. 4). Later, these materials were found to be nanocom-posites consisting of metal carbide pre-

cipitates in amorphous hydrocarbon matrices (Ref. 5). Since tungsten con-taining diamond-like (W-DLC) coat-ings can usually be deposited at tem-peratures below the tempering points of engineering steels, they are currently utilized in many mechanical applica-tions (Ref. 6). Generally, W-DLC coat-ings are two to three times harder than steel, use Cr adhesion layers, are less than three micrometers thick and have low friction coefficients when sliding against steel.

Like some other bearing manufactur-ers, Timken has used commercial coat-ings, such as W-DLC, for many years to provide wear resistance to rolling el-ement bearings. For example, W-DLC coatings have been successfully used as barriers to the adhesive wear mecha-nisms that cause false brinelling and smearing in roller bearings. However, in boundary layer lubricated environ-ments, W-DLC coatings have not ex-hibited the durability to remain intact for the entirety of a bearing’s predicted life.

The lubrication environment that a bearing or other mechanical device op-erates in is commonly defined in terms of the dimensionless parameter L which is the ratio of the lubricant film thick-ness to the composite surface rough-ness of the contacting surfaces. Fatigue life testing was performed on tapered roller bearings with a commercial W-DLC coating applied to the rollers. A standard test protocol was used where bearings were operated at 150%-rated load, based upon 90 million revolutions, in a L = 0.5 lubrication regime, and in non-additized oil. Although the bear-ings with W-DLC coatings achieve their predicted lives at this lambda val-ue, the W-DLC coatings on the rollers exhibited non-uniform wear. Images of the bodies and ends of these rollers are shown (Fig. 3). Whereas the coatings are still strongly adhered to the steel, fracture within the coating has gener-ated non-uniform wear. Since the W-DLC is much harder than bearing steel, uneven wear of the roller coating is det-rimental to the raceway surfaces.

After a detailed investigation prob-ing the microstructures of W-DLC coatings, Timken was able to identify the defect in W-DLC responsible for

the fracture-type wear and eliminate it through an optimization of the coat-ing deposition process conditions. Bear-ings equipped with rollers with Tim-ken’s new coating were tested to their fatigue limits with the standard life test protocol described above. Rollers re-moved from the bearings at the end of the serviceable life of the bearing are also shown (Fig. 3). No visible coating wear is observed on either roller bod-ies or ends. Furthermore, coating thick-ness measurements performed prior and subsequent to the fatigue life tests are the same within the capabilities of the measurement system. This indicates that no measurable wear of the coating has occurred in this highly loaded, low lambda bearing environment.

Wear resistance of bearings with en-gineered roller surfaces. One of the life-limiting wear issues affecting main shaft and gearbox bearings in wind turbine generators is micropitting. Micropitting is caused by interaction of the raceway and roller residual finishing marks, or asperities, leading to high surface stress-es in the contact. Normal stress alone is not typically sufficient to cause a crack to initiate at or very near the surface ear-ly in the lifecycle of a bearing. Howev-er, the addition of frictional shear stress increases the bulk contact stress values and brings the maximum values closer to the surface—as shown by Harris and Yu (Ref. 7)—allowing these localized stresses under the asperity contacts to become significant. This type of interac-

tion typically occurs when the lubricant film is insufficiently thick to separate the contacts and when there is relative sliding between the two contacting sur-faces (Refs. 8–11).

Low-cycle micropitting is caused by high amounts of sliding between rollers and ring raceways, generating consider-able shear stresses in the contact zone. From the viewpoint of an element-of-area on a ring raceway, the cyclic shear stresses imparted by each passing roller ultimately generate micro-cracks that propagate in the direction of the sliding shear stress on the slower moving com-

ponent (Refs. 12–13). As these micro-cracks propagate, pieces of the raceway begin to break away from the surface, leaving micrometer-size pits.

The evolution of low-cycle micropit-ting to raceway spalling of a 230/600 main-shaft spherical roller bearing is shown (Fig. 4). Figure 4-A shows the onset of micropitting, where two distinct wear tracks have emerged in the center of the raceway. As the micropitting con-tinues, more and more material is worn away, leading to a loss of the design con-tact geometry in the center and increas-ingly higher stress concentrations at the

edges of the wear track. Fatigue spalls initiate at these areas of high geometric stress concentrations and propagate on raceways like that shown in Figure 4-B.

The raceway spalling of these bear-ings is not due to classic surface-initiat-ed or inclusion-related fatigue on which the predicted bearing life is calculated, but is due instead to the loss of the de-signed contact geometry due to micro-pitting wear and a concomitant increase in geometric stress concentrations at the edges of the roller/raceway contact. Since there exists a high amount of slid-ing between the rollers and raceways in a spherical roller bearing, it is not un-usual to observe micropitting wear of these bearings in low-lambda condi-tions. For example, images of spherical roller bearing raceways that have been fatigue life tested at low lambda (L~0.5) are shown (Fig. 5).

To stimulate early fatigue, both bear-ings were deliberately damaged with steel debris prior to life testing. The top image shows a raceway that ran against uncoated steel rollers, with the gray band of micropitting clearly vis-ible. No indication of micropitting is observed on the raceway in the bottom image that ran against rollers with Tim-ken’s engineered surfaces. Clearly, a sig-nificant reduction in the shear stresses between rolling elements and ring race-ways can eliminate the mechanisms re-sponsible for low-cycle micropitting in roller bearings.

Another wear mode that damages bearings in applications like wind tur-bine gearboxes is smearing. Like micro-pitting, smearing in bearings also occurs when rollers are skidding against race-ways in low-lambda conditions. But, whereas micropitting is a microscopic surface fatigue mechanism, smearing occurs when the heat from the friction between the sliding rollers and the race-ways generates local temperatures in the contact zone high enough to melt the steel surfaces. The large-scale plas-ticization and localized melting gener-ates a smeared appearance on the race-way surface. FeO is sometimes found in the smeared wear patch, which indicates that the local temperature in the contact zone exceeded ~550 °C.

A simple bench test has been per-formed to demonstrate the ability of

Timken’s engineered surface (ES) to in-hibit smearing or scuffing-type wear. In this test, two highly loaded steel rings were placed into contact with 150% slide/roll ratio and the lubricant en-trainment velocity was reduced in stages until a spike in the frictional torque was observed. In one experiment untreated steel rings were used; in the other, a steel ring with an engineered surface was run against an as-ground ring. Images of the ring pairs are displayed (Fig. 6).

The pair of as-ground steel rings expe-rienced smearing wear that progressed very rapidly to galling. However, since no frictional torque spike was observed while the ES-treated ring ran against the as-ground steel ring, it is concluded that smearing wear did not occur within the load and speed limits of this experi-ment. Examination of the ES-treated ring surface indicates no visual signs of wear. Since no smearing occurred when the ES-treated ring ran against the as-ground steel ring, the frictional heating at that interface must have been consid-erably lower than in the contact zone of the untreated steel rings.

Debris damage is another wear mode known to affect bearing life. As indi-cated (Fig. 5), the debris damage of the spherical roller bearings made from through-hardened AISI 52100 reduced the actual life of the bearings with un-treated rollers by between 30–40%. However, the same debris damage on an identical spherical roller bearing with ES-treated rollers suffered no statistical reduction in life.

Another laboratory-scale test was constructed to quantify effects of debris damage on the actual lives of case-car-burized tapered roller bearings. In this test, bearings were rotated under load for a specific duration in AISI 52100 debris-laden oil. The debris particle siz-es were between 25 and 53 mm with a 0.5 mg/ml concentration in the SAE 10-weight lubricant. Next, the bearings were solvent cleaned to remove the de-bris. Finally, the bearings were life-test-ed using a first-in-four failure criterion in clean SAE 10-weight oil.

Statistically significant populations of bearings with untreated rollers and bearings with ES-treated rollers were tested. Results of those tests are shown (Fig. 7) where the L16 values and upper

and lower 65% confidence bands (tops and bottoms of the bars) are normal-ized to the baseline test results. Since the fracture toughness of case-carbu-rized steel is two to three times that of through-hardened steel (Ref. 14), the reduction in the lives of (equivalent) case-carburized bearings due to debris damage is less than that of through-hardened bearings. Also shown in the figure is an optical image of a debris dent in a bearing raceway and a 3-D surface profile of the dent. Statistically, the bearings with the ES-treated roll-ers had an L16 life more than three times greater than the life of identical bear-ings with untreated rollers.

The mechanism by which ES-treated rollers make bearings tolerant to debris damage is clearly illustrated (Fig. 8). The image of the debris dent (Fig. 8-A) is from a raceway that ran against un-treated steel rollers and shows that the raised edges around the crater formed from the debris are still in place. On the other hand, the image of the debris dent (Fig. 8-B) is from a raceway that ran against ES-treated rollers. All traces of the raised edges have been removed as have the residual grinding lines. It is the ability of the ES-treated rollers to remove the raised edges around debris craters that negates the fatigue-life-re-ducing mechanism associated with de-bris-damaged raceways.

Due to large entrainment velocities, thick lubricant films usually exist at the rib-roller end-sliding contact of a ta-pered roller bearing. Situations occa-sionally occur where the lubricant film at this interface is insufficient to sepa-rate the asperities of the roller end and rib face. In these situations, adhesive wear between the asperities can lead to scuffing, scoring and, eventually, galling. Examples of situations where this adhe-sive wear can occur include the use of ultra-low-viscosity lubricants, large axi-al loads, highly loaded high-speed oper-ation and lubricant interruption or loss.

A laboratory test was devised to mea-sure the resistance to rib-roller end-failure of tapered roller bearings with ES-treated roller ends. The test was designed to mimic a field condition where bearings in gearboxes experi-enced an extended lubrication loss con-dition. Test bearings were immersed in

Figure 8—3-D profile topographies of debris dents on bearing raceways measured after life testing. The image of the debris dent in “A” is from a raceway that ran against untreated steel rollers, and shows that the raised edges around the crater formed from the debris are still in place. On the other hand, the image of the debris dent in “B” is from a raceway that ran against ES-treated rollers. All traces of the raised edges have been removed, as have the residual grinding lines. It is the ability of the ES-treated rollers’ ability to remove the raised edges around debris craters that negates the fatigue life-reducing mechanism associated with debris-damaged raceways.

Figure 9—Results of a lubricant starvation test on tapered roller bearings with standard rollers and ES-treated roller ends. The ES treatments on the roller-ends provided a barrier to the adhesive wear that causes scuffing and scoring, and allowed the bearings to operate under full loads and speeds approximately nine times longer than identical bearings with standard rollers.

a solution containing 80% hexane and 20% GL-5 gear oil. Upon removal from the solution, the hexane was allowed to evaporate, leaving behind a thin oil film on the bearing surfaces.

Figure 9 displays the time to rib-roll-er end scuffing for bearings with and without ES-treated roller ends. At least 25 bearings were tested for each condi-tion; results were analyzed using first- in-one Weibull statistics and 90% con-fidence bands were calculated around L50 lives. Whereas uncoated baseline bearings had an L50 value of about six minutes, bearings with ES-treated roller ends had L50 values of about 50 min-utes.

The ES treatments on the roller ends provided a barrier to the adhesive wear that causes scuffing and scoring, thus allowing the bearings to operate under full loads and speeds of up to nine times longer than identical bearings with standard rollers. Wear-resistant bear-ings with ES-treated rollers are cur-rently being used in the metal forming and agricultural industries, as well as in flight-critical aerospace systems.

False brinelling or fretting is an ad-hesive wear mechanism that can oc-cur between rolling elements and races whenever a non-rotating bearing is sub-jected to external vibration. Under these conditions lubricant is squeezed from between the contacts and the relative motion of the surfaces is too small for the lubricant to be replenished. Natural oxide films that normally protect steel surfaces are removed, permitting metal-to-metal contact and causing adhesion of surface asperities.

Fretting begins with an incubation period during which the wear mecha-nism is mild adhesion and the wear de-bris is magnetite (Fe3O4). Damage dur-ing this incubation period is referred to as false brinelling. If wear debris accu-mulates in amounts sufficient to inhib-it lubricant from reaching the contact, then the wear mechanism becomes se-vere adhesion that breaks through the natural oxide layer and forms strong welds with the steel. In this situation the wear rate increases dramatically and damage escalates to fretting cor-rosion. Relative motion breaks welded asperities and generates hematite (a-

Fe2O3)—a fine powder, reddish-brown in color.

A laboratory-scale testing apparatus was designed to evaluate the ability of ES-treated rollers to inhibit false bri-nelling in bearings. Standard bearings with steel rollers and wear-resistant bearings with ES-treated rollers were tested. All bearings were lubricated with GL-4 transmission gear oil before test-ing. The test apparatus applied an oscil-lating 18.7 kN axial load to the bearings for 500,000 oscillations—conditions identical to a bearing application that experienced false brinelling in the field.

Subsequent to testing, depths of the grooves produced on the outer race were

measured. Figure 10 displays the aver-age wear depths and standard devia-tions for the standard and wear-resis-tant bearings. After testing, the standard bearings exhibited grooves on the race-ways with average depths of 1.85 mm. On the other hand, the wear-resistant bearings had average groove depths of only 0.68 mm. The wear of the raceway oscillating against the ES-treated roll-ers was very slight and appeared to be caused by gentle lapping rather than ad-hesive wear.

Examples of applications that use wear-resistant bearings to eliminate false brinelling include off-road truck

Low L fatigue life of bearings with engineered roller surfaces. Bearings have generally been selected according to the dynamic and static load ratings. The dy-namic load rating C1 is a measure of the bearing’s ability to withstand roll-ing contact fatigue, which by typical in-dustry practice is according to the ISO load and life rating standard (Ref. 15). The static load rating C0 is a measure of the bearing’s ability to withstand the maximum-applied load without func-tion-reducing, permanent deformations or bearing ring destruction according to ISO standard 76 (Ref. 16). The dynamic load rating is used in the ISO 281 stan-dard life rating equation for roller bear-ings: (1)

Lnm = a1 aISO ( C1 )10.3

Pwhere:a1 is the life modification factor for re-

liability,aISO is the integrated life modification

factor accounting for material, lubri-cation and hard particle contamina-tion,

and Lnm is the modified rating life in millions of revolutions.

Nominally, roller bearing endurance is calculated as L10, the rolling contact fatigue life in millions of revolutions that 90% of the bearings will survive. Detailed calculations to predict aISO are given by Harris, et al. (Ref. 17) and indi-cate that if a roller bearing is operated in low-lambda conditions (L<1), aISO and L10 become small.

Full-scale life testing has been per-formed on standard and wear-resis-tant bearings with ES-treated rollers in L 0.5 conditions. All bearings were life-tested using a first-in-four failure criterion in clean SAE 10-weight oil at 150%-rated load at 90 million cycles.

Statistically significant populations of standard and wear-resistant bearings were tested. Results of the L = 0.5 tests are shown (Fig. 11) where the L16 values and upper and lower 65% confidence bands (tops and bottoms of the bars) are normalized to the standard bearing test results.

As indicated (Fig. 11), the relative L16

life of the wear-resistant bearing with ES-treated rollers is more than five times that of a standard bearing operat-ing in low-lambda conditions.

The mechanism by which this large boost in low lambda bearing life is achieved is revealed in an examination of the 3-D topographic profiles of the raceway surfaces in Figure 12. In the low- lambda life test described above, one standard and one wear-resistant bearing were removed from testing after about 44 million cycles, and the race-ways of the outer rings were measured by 3-D optical profilometry. Whereas the topography of the raceway of the standard bearing remained essentially unchanged after 44 million cycles, the raceway of the wear-resistant bearing has been highly polished.

Calculations based upon this high-ly polished surface and the Hamrock-Dowson (Ref. 18) lubricant film thick-ness yield a lambda value greater than two. Therefore, although the lambda val-ue calculated from the initial surface pa-rameters was 0.5, the ES-treated rollers have dramatically polished the raceways such that the wear-resistant bearing is effectively operating in an elastohydro-dynamic L~2 regime.

SummaryTable 1 summarizes the application

advantages of wear-resistant bearings with ES-treated rollers. Since bearings seldom operate in fully lubricated en-vironments, they rarely experience the number of cycles for which they were

designed. In low-lambda situations the ES-treated rollers in wear-resistant bearings polish the ring raceways— ef-fectively increasing the separation of the contacting asperities. This polishing action continues until the contacts are fully separated by the lubricant film and the bearing is no longer operating in a low-lambda situation.

Interruption of the supply of lubri-cant to bearings can result in adhesive wear between the rollers and contact-ing surfaces on rings. Depending upon the loads and speeds, the adhesive wear rates increase until scuffing, scoring or galling occurs. ES treatments on roll-ers will not participate in adhesive wear with raceway asperities, but if the loads and speeds in the contacting areas are large enough and the lubricant inter-ruption is long enough, the coating on the rollers will wear through graphitiza-tion. However, once the coating is worn away, adhesive wear ensues; while the coating is wearing, it allows the bearing to remain operational.

Abrasive particles that pass through worn seals that were not removed af-ter manufacture—or are generated by wear of other components—can dam-age bearing surfaces if the particles are larger than the lubricant film. Depend-ing on the hardness and brittleness of the particle, they can generate dents on the raceway and/or roller surface. Dur-ing the denting process, displaced ma-terial creates shoulders around the de-bris crater. When these raised shoulders come into the contact zone of a bearing, very high, sub-surface stresses are gen-erated and fatigue cracks initiate at low stress cycles (Ref. 19).

Because the ES treatments on the rollers of wear-resistant bearings are twice as hard as the steel raceways, they remove these shoulders through the same kind of polishing action described above. As a result, the stress risers that

can cause early fatigue crack initiation are removed, thereby allowing the bear-ing to operate much longer than it oth-erwise would.

When lubricant film is insufficient to keep loaded steel surfaces in relative motion from coming into contact, ad-hesive wear occurs. If high loads are ap-plied to skidding rollers, the frictional heating from the adhesive interaction of contacting asperities can increase the temperature in the contact zone to the point where the steel actually melts. This melting and subsequent re-solidifica-tion process weakens the steel and cre-ates a smeared appearance when it oc-curs on bearing raceways.

The shear stresses from moderate loads applied to skidding rollers can cre-ate bearing damage known as micropit-ting. Very high transient loads applied to skidding rollers can generate near-surface stresses on non-metallic inclu-sions, creating cracks that propagate and remove thin pieces of the raceway. This type of damage is known as brit-tle flaking. ES treatments on wear-re-sistant bearings provide a barrier against the ability of raceway asperities to bond to the roller and reduce the shear stress-es and frictional heating from skidding rollers that cause these bearing damage modes. By decreasing the shear stress-es of skidding rollers, the maximum contact stress is driven deeper into the raceway, well beyond the region where cracks that cause brittle flaking origi-nate.

Roller bearings with smooth race-ways exhibit less frictional torque than bearings with rougher raceways. Since the ES-treated rollers in wear-resis-tant bearings continuously polish the raceways, the contribution of friction-al torque from contacting asperities is eliminated in operation. Depending upon the application and the type of bearing, raceway polishing by ES-treat-ed rollers can reduce parasitic bearing losses between 5–10%.

David Brown Bharat ForgeOPENS fIRST GEARbOx CENTER

David Brown Bharat Forge, the Indian joint venture between David Brown and Bharat Forge, recently celebrated the opening of its first industrial gearbox service and assem-bly facility in Hosur, Tamil Nadu, India. The state-of-the-art facility was officially opened by chief guest SP Singh, direc-tor, NTPC Ltd. at a ceremony attended by distinguished guests as well as the Chief Executive of David Brown Bharat Forge, Venkatesh Subramanyam; Executive Director of Bharat Forge, Subodh Tandale; and David Brown’s Commercial Director Gavin Money.

The guests were given a guided tour around the facility, which is fully equipped with an industrial crane and has the capability to service, repair, upgrade and provide strategic gearbox maintenance as well as supply new gearboxes for customers in industries such as mining, power generation, metals, cement and renewables as well as the defense sec-tor. The 56,000 square ft. service, repair and assembly center provides support to customers across India, giving them access to more than 150 years of engineered gearing innovation and expertise. Service Centre Manager Kumaran Vajravel showed the guests a vast range of equipment, including a 100-ton hydraulic vertical press, lathe, milling machine, a spray booth and other service-specific tools and equipment alongside gearboxes from wind and steel applica-tions which have already been sent to the center for repair.

“As the largest power utility company in India, NTPC welcomes David Brown and Bharat Forge’s decision to join forces and form a joint venture company for the local mar-ket. Both partners have decades of combined experience and are known for their high quality products and solutions—I believe they have found an ideal partner in each other.

Micro PrecisionANNOuNCES INDIA AND CHINA ExPANSION PLANS

Micro Precision, a U.K. precision engineering business with established credentials in manufacturing geared com-ponents and a large range of other precision engineered components and assemblies to the industrial, aerospace and automotive sectors recently announced the opening of its first satellite manufacturing plant in India.

Following an exhaustive planning and field research exer-cise Micro Precision has opened its first production site in Bangalore, India. Initially the operation will develop and manufacture a range of new gear pump products with pro-duction starting in October 2012. The products will be sold internationally as well as to the local domestic market where demand for precision engineered components is growing exponentially.

Already planning the next step in the expansion of its pro-duction base in India, Micro Precision has also purchased a three-acre site on the fast developing Bangalore Aerospace


N E W SBusiness Park. The intention with this facility is to expand the company’s medium- to high-volume manufacturing operations. This site will concentrate on the production of aerospace and automotive components and is expected to reach full production capacity by mid-2014.

This new large production facility will complement the U.K. business satisfying demand from the fast growing Indian market but also providing a low-cost medium- to high-volume solution for U.K. activities and export markets. The plan and business model has been greeted with whole-hearted support from the company’s major clients, who are also under pressure to outsource production to trusted suppli-ers such as Micro Precision.

Far from creating concerns among the fastidious European aerospace engineering community, initial industry feed-back already received to the news from Micro Precision is extremely positive —with most viewing the move as shrewdly anticipating the changing demands of the dynamic global aerospace sector.

The plan is for the U.K. operation based in Hemel Hempstead to continue production of short-run items and ‘specials’ while developing its status as an R&D center of excellence, retaining its experienced design, engineering and production team, plus the huge range of specialist machine tools, testing and inspection facilities.

The development center at Hemel will retain the low-volume manufacturing base facilities while developing and optimizing more new part programs to be put into production by the high-volume manufacturing plant in India, and later a second site planned in China by 2015. The business will also continue to develop prototypes, manufacture spares, legacy components and will continue to service its domestic and European clients.

Commenting, Micro Precision Managing Director and Founder Terry Grubb said, “In addition to establishing sales further afield, we are also presently extending our sales activities closer to home in France, Italy and Germany and

demand is certainly growing for higher volume production runs. All our products will be supported by the technical expertise built-up over many years in the U.K. and as the higher volume manufacturing activities come on stream, the U.K. facilities will also act as a logistics hub for a propor-tion of re-imported Micro Precision products manufactured by us in India and eventually, China. We are by no means reducing our U.K. footprint, but simply defending the long-term success and viability of the business by taking advan-tage of being able to supply new markets and geographical areas where demand is booming more cost effectively, while retaining our integrity and skills base.”

KlingelnbergAWARDED DOCuMENTATION PRIzE

The Klingelnberg Group has received awards for the second year in succession for the quality of its operat-ing instructions – this year with no fewer than four com-mendations. The company received prizes for all four of its submitted operating instructions.

“Due to the technical com-plexity of our machines, we naturally provide the users with very complex operating instructions, and precisely for this reason it is important to us that these are comprehensibly structured, formulated and illustrated in accordance with needs of our target groups,” explains Pascal Kesselmark, head of technical documenta-tion of the Klingelnberg Group.

Tekom (Gesellschaft für Technische Kommunikation e.V.) had previously awarded the company two prizes in 2011. The operating instructions for four machines were singled out for prizes this year: the Oerlikon spiral bevel gear cutting machine C 50, the Oerlikon tool grinding cell for bar blades B 27, the Oerlikon spiral bevel gear lapping machine L 60 and the Klingelnberg measuring center P 65.

Dr. Hartmuth Müller, CTO of the Klingelnberg Group, is absolutely delighted with the awards: “We regard them as a validation of our meticulous work in this area. For us it is not only a matter of simple compliance with the Machinery Directive, but far more a question of our responsibility towards the users: we supply instructions that enable safe utilization of the technology. Only then do they guarantee an intuitive and smooth machine operation in conjunction with innovative control concepts.”

Tekom has been awarding its renowned documentation prize, an independent prize recognizing user and operating instructions for consumer and investment goods as well as online help for software products, since 2005. The review-ers take into account an extensive list of criteria that, with an eye on user-friendliness and operating safety, places special emphasis on: structure and text, illustrations, design/layout, safety instructions, navigation, scope, and a comparison between the documentation and the actual product.

ANCAWINS ExPORT AWARD

ANCA has won the Large Advanced Manufacturer cat-egory in Australia’s Governor of Victoria Export Awards for the 7th time. According to the company, 2011 was an excep-tional year of growth for ANCA, an Australian owned and based market leader in CNC tool and cutter grinder design and manufacturing. Pat Boland, co-founder and director of ANCA, made the announcement.

ANCA makes a significant investment to the Australian economy with 98 percent of its products exported globally with major markets in Germany, Japan, China and the United States. ANCA has defied the odds to achieve success on a global scale in a sector traditionally dominated by German and Swiss companies.

The award is one of the most prestigious business awards in Victoria rewarding the most successful and innovative exporters with the stamp of international success.

ANCA reported almost 20 percent export sales increase FY2011/2012 with significant success developing the Chinese, South American and Indian markets. As the EU continues to struggle, ANCA had its most successful trade show at EMO exhibition with the highest sales ever achieved in its 38 years and has launched new machines and software into the market to remain at the forefront of machine tool technology.

Boland said “This award is an endorsement of the hard work and innovative thinking of the team at ANCA. We con-tinue to push the boundaries, developing even more flexible and sophisticated products and identifying new un-tapped global markets to sell to. I am proud of the success of our business and our amazing talent that enable us to be the mar-ket leading business we are today.

“Given that we are based in Australia but sell to the world, we have to be the best of the best. Our investment in research and development from the beginning has instilled a culture of excellence where we continue to seek out new and better innovations for our customers.”

The business continues to invest heavily in research and development, create industry firsts and has built a special-ist team of around 350 at its head office in Bayswater, Melbourne. Founded in 1974 the business is a market lead-ing manufacturer of CNC tool and cutter grinders.

INsight

Teaching science, technology, engineering and mathemat-ics in order to motivate young minds goes far beyond a textbook. BrainCafé Science aims to reach out to schools across India and enable them with an innovative and inter-active learning environment. Its mission is that “learning by doing” leads to a sustainable understanding and greater technical skill set for the next generation of workers.

BrainCafé was created by Zee Learn Ltd., a leading education company in India that boasts 200+ skilled profes-sionals that offer educational services from toddlers to teens to young adults. The company strongly believes that every child has unique, infinite potential and they are committed to helping kids recognize their various skill sets.

Recently, BrainCafé organized the BrainCafé Budding Scientist Contest 2012 in Moradabad to motivate young minds with scientific learning. Experiments included

launching a rocket as well as creating an LED screen. The competition observed participation from 50 students across 15 schools showcasing their talent in the field of science. The event took place at Wilsonia Convent School, Moradabad.

Students from renowned schools across cities such as Moradabad, Allahabad, Jhansi, Varnasi, Meerut, Agra, Etawah and Hardoi participated in this event. Amongst the schools that participated were, Vishnu Bhagwan Public School, St. Joseph’s College, Mount Litera Zee School, The Holy Angels School, Wilsonia School, St Xavier’s School, Bal Vidya Bhavan Public School, Aryan International School, Kosi Public School, Smt. Chameli

Devi Gyanashram, Kaushambi Preseidency School and Heritage School.

“The BrainCafé Budding Scientist Contest 2012 is one of India’s largest science competitions providing students with a unique platform to showcase their ability to apply scientific principles into working models. Held across dif-ferent levels, from School to the National level, the contest attempts to develop High Order Thinking Skills (HOTS) among students through the route of science. The BrainCafé technique enables ‘Learning by Doing’ through a unique teaching methodology, based on Observe, Explore and Reflect,” says Amanpal Singh, business head at BrainCafé. “In order to motivate participants to encourage innovation, BrainCafé offers an international trip to the first prize win-ner from each category. The student can bag a chance to visit Japan’s Gakken Educational Company.”

BrainCafé Budding Scientist Contest 2012 has registered and observed participation from 9,500 students across 240 schools in the coun-try. “The range of innovations demonstrated by BrainCafé students during the contest has been beyond belief. From hydraulic lift to elevator, solar car to rotating lamp, barometer to wind mill—the diversity of creativity was phenomenal. The projects were demonstrated applying the BrainCafé system of learning scientific principles.”

According to a 2010 report from the United Nations Educational, Scientific and Cultural Organization (UNESCO), India remains one of the fastest growing economies alongside China. While the past few years have shown a rise in R&D investments, the country has also seen a growing number of foreign compa-nies establishing R&D centers on Indian soil.

One of the country’s greatest challenges is the steady flow of highly skilled workers outside of India, making it dif-ficult for domestic firms to compete. Thankfully, the Indian government’s decision to create more than 30 universities across the country, including 14 world-class innovation facilities, points toward a more optimistic future for the next generation of skilled workers.

BrainCafé aims to help India support science, engineer-ing and mathematics for generations to come. To see some of the students that have created these innovations and are now a part of the website’s “Hall of Fame,” please visit www.braincafeindia.com.
