In order, in a geared motor with a worm gear, consisting of a worm shaft (23) on a rotor shaft (2) extended into a gear-housing part (3) composed of a flanged-on motor-housing part (1) of an electric motor, and of a worm wheel (31) meshing therewith and located in the gear-housing part (3), to make it possible to do without seal of the latter against moisture relative to the outside, a worm wheel (31) made of POM plastic with admixed slide-modified POM plastic is provided; with an admixture ratio of approximately 20%-50%, advantageously self-locking between the worm wheel (31) and the worm shaft (23) can be guaranteed, even over long operating times, at the conventional pitch angles of the worm shaft (23). <IMAGE> |
