Actuator with a in a transmission housing formed support ring for radial force supporting a in transmission housing rotary mounted worm wheel

摘要

Adjusting drive has a drive unit and a gear unit (2). A toothed ring (11) of the worm gear (6) is mounted in a sliding fashion with its bearing face (17) on the support face (19) of the support ring (12). A segment of support ring is projected, in the region of worm engagement (18), into the toothed ring. A segment of support ring is projected to such an extent that a component of the drive force (FR) which acts radially with respect to the drive output axis (AB) is introduced on the same, straight line of action (WR/W1) into the support ring of the housing via the toothed ring of the worm gear.
