Planetary gear for mounting on electric motor, has sealing element between sun wheel shaft, and housing arranged axially outside output shaft accommodation region in reduced diameter section

摘要

The planetary gear has planetary wheels (10) mounted in a bearer (8) forming an output drive and simultaneously engaging a sun wheel (12) and a fixed hollow wheel (14), whereby the sun wheel is connected to a rotatable sun wheel shaft (4) that is hollow to accommodate a motor output shaft. A sealing element (22) between the sun wheel shaft and the housing is arranged axially outside the output shaft accommodation region (16) in an axial section of the sun wheel shaft with its external diameter reduced compared to the accommodation region.
