Introducing Kumera Active Drive™Kumera’s commitment to research and development is continuously resulting to new products and solutions. Latest achievement of Kumera’s R&D team is a new drive solution for girth gear applications. The solution has been named as KAD, which stands for Kumera Active Drive™.

KAD is designed to ensure optimal load distribution on girth gear teeth throughout years of operation without a need for high accuracy alignment. This compact solution utilizes the full load capacity of the valuable girth ring while providing maximum usability and serviceability with minimum space requirements.

Conventional girth gear drives have significantly high demands when it comes to alignment accuracy. When

KUMERA Active Drive™ is utilized, the only accurate dimensional requirement needed at installation is the tooth backlash. The lateral alignment tolerance is as rough as 3 mm / 100 mm.

KUMERA Active Drive™ independently optimizes the tooth contact by constantly modifying the alignment of the drive unit. This enables girth gear load ratings that are unreachable for conventional drives.

Allowed by the exquisite structure of KUMERA Active Drive™, a user friendly backlash adjustment system is integrated to the drive unit. Adjustment is performed simply by rotating a single adjustment screw. The resulting backlash can be calculated in relation to revolutions of the adjustment screw.

Turnkey Delivery for Limestone Kiln in FinlandIn the middle of 2013 Kumera was selected as a supplier to modernize demanding limestone kiln drive system in Southern Finland. The nearly 80 meters long kiln with diameter 3,3 meters had 20 years old drive system with all the components approaching the end of the life cycle.

Environment issues, easy maintenance and high efficiency were the key issues when selecting and designing the new drive unit. Instead of having all the components on separate foundations Kumera designed the new drive system so that the main pinion is located directly on the low speed shaft of the main

gearbox. As well the auxiliary drive with diesel engine and necessary couplings and brakes were integrated to the main gearbox. This design enables easier adjustment of the main gear teeth contact. No other alignments are needed when the whole drive package can be lifted and adjusted as one unit.

Girth Gears from Kumera ChinaKumera has met yet another milestone in the development of its operation in Kunshan, China. Together with the technology transfer from the headquarters in Finland and investment to advanced 5-axiles CNC machine center, Kumera China is now able to manufacture and deliver complete Girth Gear applications. The delivery capacity today includes complete package from girth gear and main drives to lubrication system, auxiliary drives, clutch, brake and coupling.

The Yankee gear unit series is built on the proven foundation of Kumera’s design and manufacturing system, combining decades of extensive experience with trusted quality. These simple and efficient gear units provide high reliability and life expectancy for the toughest tissue-making processes.

Assembly, test run, painting and packing were done at the Kumera Kunshan factory as well as machining of all the shafts, gearwheels and the casted housings. The project itself was a good example of global teamwork within Kumera Power Transmission Group with smooth co-operation between units in terms of design, assembly instructions, fixture design and procurement.

Drum Pulper Gear Production Start-up in Kumera ChinaRPV-2x425Z was the first totally new product to have production ramp-up in China without previous manufacturing experience from Kumera’s European locations.

Two different using positions and size of the gear unit made assembly and the test run more challenging than for the standard gear units. Global specialist team was in place for assembly and test run. The casting housings for RPV-2x425Z were the largest manufactured by Kumera China with a total width of 2490mm and weight of 1,65 tons. The gearwheels and shafts, including the heat treatment and special teeth form requirements were produced according to proven Kumera standard processes.

Next Generation of CUMEX Gear Coupling SystemThe next generation of CUMEX Gear coupling System, KK- Series provides optimal solutions for the customer – one supplier for the whole drive system. The new system is extremely

compact and provides higher torques. New design and improved material quality and geometry offer the customer a better serviceability and ease of assembly.

Meeting IMO Emission Standards with Kumera Marine Green Drive™

Kumera AS is contracted by Vard Brevik and the Norwegian tow boat company Buksér og Berging AS to develop,

engineer, test and deliver a 2-step main propulsion mechanical

transmission with multiple power take offs. The new invention is instrumental in Buksér

og Berging’s strategy to meet the International Maritime Organization’s (IMO) rules for reduced NOx /SOx emissions in 2016 with developments based on traditional mechanical solutions.

The drive is designed to employ the two diesels separately one at the time or in parallel giving maximum power transmitted. The main transmission is 3.4m in width weighing about 8 ton each.

The Kumera scope of supply for Buksér og Berging AS includes a port and starboard mechanical power transmission. The delivery is scheduled for mid-September 2014. The know-how and technology of making gears for twin engines have rested with Kumera for many years with many reference projects.

Kumera Hydraulic Clutch serie ranging upKumera develops new hydraulically engaged clutches to cover needs of new Kumera AS’s marine Green Drive. New types scale up to range of the current NKH-clutch serie. Nominal torques for the new clutches are 30 and 65 kNm. Design is made in co-operation between Kumera Norway and Finland. New clutches will be used in the main propulsion line. Handling of the thermal loads, cooling, controlled engaging disengaging and wear are the key issues to fulfill the high requirements of the new Green Drive. New clutches will pass heavy endurance tests before accepted to use in ships propulsion line.

Kumera Gearbox to Gasturbine at Helsingin Energia Power Plant

The power plant operates as a national disturbance reserve and is an important part of preparing for the need of rapid disturbance reserve. The stand-by power plant uses fuel oil to produce electricity and the capability is 120MW. The use of the gearbox is to transmit the power from diesel engine to the turbine during the startup. Between the diesel engine and main gearbox there is already Kumera LX-gearbox raising the diesel engine rotation speed to the correct level.

The delivery scope of the contract is the main gearbox with installation. The base of the gearbox is welded steel structure housing. Because of the high diameter and high rotation speed of the shafts, all the shafts are supported with tailor made sliding bearings. All the gearwheels are using double helical toothing to allow the maximal transmittable torque and to avoid the axial loads. All the tooth contacts are pressure lubricated to ensure the proper lubrication and to

transfer the heat. This maximizes the teeth lifetime. Sliding bearings are also pressure lubricated and they are equipped with separate high pressure support oil flow to allow the low speed rotation.

Gearbox is epuipped with connection for the existing auxiliary drive, which allows the gearbox to be used with low rotation speed to cool and rotate the turbine after the use or for the maintenance work. The input shaft is

Helsingin Energia is one of the biggest energy companies in Finland. They sell energy to about 400 000 customers and district heat to over 90 percent of properties in Helsinki. Last year they decided to replace the existing turbine gearbox in Kellosaari power plant and selected Kumera as their gearbox supplier.

Next generation of the Kumera Anode JackDuring the past decades Kumera Drives has equipped several Aluminium Smelters with Anode Jacks. More than 30 000 Jacks are delivered and most of those are still in daily operation.

Development of the latest flagship of the jack fleet, KDAJ-40 was started in 2007. Jack’s lifting capacity is 40t and design is so called “Spherical Jack”

– meaning lifting screw’s ability to tilt all around its apex point. Spherical action is needed to allow needed pot’s structures lateral movement during different process phases.

The new design was put under extreme testing conditions. Jacks were operated continuously up and down by 45 t load day by day under 180 C temperature. Different test cycles were undertaken based on reduction cycle therefore enabling full HALT (Highly Accelerated Life Time) test. 1500 units of this new design has already been delivered and it has has been found to be very reliable and trouble free.

inputs are included for connecting sensors for measuring for example humidity or viscosity of lubrication oil. Measurement results are stored inside the Guard Gear 300 internal memory and they are accessible from web browser based user interface. Connection to Guard Gear unit can be taken via cabled Ethernet or wirelessly with a laptop with Bluetooth or GPRS/3G. Sensor data for real-time monitoring is available via Ethernet/IP (Industrial Protocol) communication technology.

Guard Gear 300 offers a set of tools that benefit in gearbox condition monitoring: Vibration spectrum, Algorithm for lubrication oil lifetime estimation, Algorithm for automatic set of vibration levels, Graphical presentation of measurement results and a notes tool for markups of condition development.
