ELEKTRISCHES ANTRIEBSAGGREGAT, INSBESONDERE FUER WISCHERMOTOR

摘要

An electric drive unit, in particular for a windscreen wiper, comprising a motor housing (10) with a gear housing (12) secured thereon. The armature shaft (14) projects into the gear housing (12) and worm gear toothing (16) provided thereon co-operates with a worm wheel (13) mounted in the gear housing (12). The armature shaft (14) is guided in self-adjusting bearings (21, 22), provided on opposite sides of the toothing (16), whereby canting between the shaft and its guide bearings is reduced, if not eliminated, in an economic manner.
