Final Report Abstract

In the project, it was shown that the flank pressure and the tooth root stresses can also be calculated correctly for beveloids with crossing axes in an FE-based tooth contact analysis. A back-to-back test rig for beveloid gears was developed and set up for validation purposes. In addition, a method was developed with which the microgeometry of beveloids with crossing axes can be optimized with regard to several criteria and target variables. Among other things, the manufacturing influence on the microgeometry as well as the tolerances and manufacturing deviations that can be achieved in the real process are taken into account. The tooth contact analysis validated for beveloids with crossing axes, in conjunction with the microgeometry design method, thus enables the load-carrying capacity and power density of the beveloid gearing to be increased, thereby contributing to the optimal utilization of resources. Particularly with regard to use in vehicle drivetrains and mobile applications, an increase in the power density of the gearing represents added value for the entire application.
