Input gear coupling with low friction coefficient

prototyp

The input gear coupling with a low friction coefficient takes into account the requirements for small space which is around transmission, transmitted torque and high speed, which are on the input shaft to the transmission. Both joints are realized using specially designed gearing. While the rings use internal straight gearing, barrel gearing is used on the hubs. Engagement of these types of gearings allows tilting and thanks to the pair of gears it is possible to connect two non-running shafts with time-changing radial displacement. In addition, the wider toothing on the rings allows displacement in the axial direction. Each of the gear coupling halves is designed so that oil can be applied to the gear engagement area. This states sealing requirements, and a bellows-shaped metal seal is used based on the axial displacement requirement. In order to reduce the coefficient of friction, increased attention has already been paid to tuning the precision of tooth production, which is crucial for the application of a uniform coating layer. Due to the achieved results of the functional sample, the design of the prototype key components of the input coupling with a low coefficient of friction was retained, design modifications were applied to the metal bellow sealing with the goal to increase component lifetime. The attention was paid to tuning the production method of individual segments in order to streamline production and thus reduce production costs.
