摘要

The unit (10) has a transmission housing (14) provided with a circular housing bottom (24). A transmission gear wheel (20) is rotatably supported on a housing fixed bearing pin that extends in an axial direction. The housing bottom extends over different planes that are axially spaced. The housing bottom is arranged in different axial planes with respect to a circumferential direction (40), where a material thickness of the housing bottom is constant. The bottom exhibits partially-circular recesses (32).
