Abstract

A series of gear motors, a gear motor, and a planetary-gear stage includes planet wheels that mesh with a sun wheel and inner gear teeth provided for the gear housing. The planet wheels are supported in a rotatable planet carrier, which forms the power take-off, and to which a sealing element is assigned on the output side. The planetary-gear stage is assigned a further sealing element on the input side. The gear housing is shaped on the input side such that an interface is formed for connection to further components, which include at least one shaft connected to the sun wheel.
