The KISSsoft System Module is a user-friendly tool also for load spectrum calculation designed for gearboxes. It incorporates nominal boundary conditions, variable forces on shafts, gear shifts, and hence changes in the power flow and operating mode variations.
This year, The Bearing Show will look at the latest developments in OEM bearing requirements, particularly with regards to future fuels and electrified drivetrains. On day one, companies including, Nexteer Automotive, FEV and HF Sinclair, Ford and GM will be presenting on evaluations of bearings within high-speed drivetrains and modern bearing challenges in automotive motion control.
Tooth contact analysis is an integral part of the gear design process. With the help of these simulation tools, it is possible to calculate the excitation caused by a tooth contact (Ref. 1). Usually, the load-free transmission error or the total transmission error under load is used for this purpose. However, the calculation with the tooth contact analysis ZAKO3D allows only a quasi-static consideration of the excitation. To better evaluate the behavior in the overall system, it is therefore necessary to perform a dynamics simulation. However, the main disadvantage of such dynamics simulations is the much longer computing time compared to quasi-static tooth contact analyses due to the high computational effort.
