With the release of version 9, the FVA-Workbench once again sets new standards in gearbox design, enabling the seamless integration of the latest research results into industrial practice. As a groundbreaking interface between collective research and application, the FVA-Workbench accelerates development and innovation in drive technology. This new release is more powerful than ever, with innovative features for flexible load spectra and improvements in FEM components and shaft-hub connections.

Drive specialist Flender has received the Supplier Excellence Recognition Award 2023 from U.S.   machinery manufacturer Caterpillar. Flender received the award for maintaining 95 percent delivery reliability and zero defects. This achievement is awarded only to the top suppliers of Caterpillar. It positions Flender as a top supplier for its global Aftermarket (Reman) Division business.

Atlanta Gear Works (AGW) is expanding its support staff by hiring its first Human Resources Specialist, a new position created to meet its expanding HR needs, previously managed by the company’s chief financial officer.

Sumitomo Drive Technologies is expanding its range of precision gear products and upgrading its ECY series with higher torque and a plug & play drive for motor connection. The ECY series comprises high-precision shaft gears, used for example for surface machining in dental technology or in collaborative robots (cobots). Thanks to their internal cylindrical roller bearings, the gear units provide both high rigidity and higher performance in a smaller design envelope.

This report derives the equation for relative elastohydrodynamic lubrication (EHL) film thickness. Mineral (MIN), polyalphaolefin (PAO), and polyalkylene glycol (PAG) lubricants with viscosity grades of ISO 320, 150, and 32 are analyzed.

Portescap introduces the new R22T gearhead, the latest addition to its existing 22 mm gearbox portfolio. As a mid-torque gearhead, the R22T fills the gap between our light-torque R22 and high-torque R22HT gearheads. It is also fully compatible with Portescap’s brush DC and brushless DC slotless motors.

Rolling bearing calculations are usually based on the assumption of ideal nominal geometries. However, actual components and assemblies are always subject to statically distributed geometric deviations resulting from the manufacturing and assembly processes. This leads to changes in the internal geometric conditions which have an effect on bearing characteristics such as the service life. The FVA-Workbench makes it possible for users to consider these geometric deviations in bearing calculations for more reliable results.

Motion + Power Technology (MPT) show brings together the gear and power transmission industries for a unique balance of education, new technologies and networking opportunities. The show takes place October 17-19,2023 in Detroit. 

The loaded tooth contact analysis (LTCA) is crucial in understanding the deformation of gears and its impact on various factors such as noise generation, contact patterns, contact shocks, and torque variations. With the contact analysis feature in KISSsoft, users can calculate tooth contact under specific torque and speed levels, thereby assessing the performance of gears and gearboxes.

Digital data models and the latest calculation methods lay the foundations for a further improvement in the performance of Generation X.e. SEW-Eurodrive continuously factors the findings of field/test stand trials and simulations into its own calculations, thereby improving their accuracy and reliability. The mechanical and thermal design of the X..e series was once again precisely evaluated on this basis. In conjunction with the component optimizations already implemented in the past, this results in even higher thermal limit ratings, a much longer bearing service life, and higher nominal torques. Moreover, larger application angles are now permissible with the maximum overhung load.
