摘要

The planetary gear has a sun wheel (2) and a sun wheel shaft (3) connected to the shaft (4) of a drive motor (5). A sealed bearing (6) is provided on the sun wheel shaft on the drive side, acting also as a stop for the sun wheel and sun wheel shaft unit, and is a plain bearing which at least in sections is contactless in relation to the sun wheel shaft at least at the operating temperature.
