<p>The invention is based on an electric motor (10) with an armature stack (12), which rests firmly on an armature shaft (14), one end of which is mounted rotatably by means of a ball bearing (40) in a pole housing (22) and the other end of which is mounted rotatably by means of a further ball bearing (24) in a transmission housing (20) and which is firmly connected at one free end to a worm (16), wherein inner bearing rings (28, 44) rest on the armature shaft (14), while outer bearing rings (30, 46) of the ball bearings (24, 40) are fitted in the housing (20, 22) in each case with a sliding fit and at least one outer bearing ring (30, 46) is supported axially on the associated housing (20, 22) via a spring element (36), wherein at least one inner bearing ring (28, 44) is supported axially towards the armature stack (12) in each case against a support (32, 48, 54, 56) of the armature shaft (14). The invention proposes that a single spring element (36) is provided on the ball bearing (24) on the transmission housing side, while the outer bearing ring (46) of the ball bearing (40) on the pole housing side is supported directly on a shoulder (52) of the pole housing (22).</p> |
