<p>The drive motor (1) is coupled with the worm shaft (4), axially movable in the housing (2) across an axially movable coupling (3). The other end of the worm shaft (4) carries an operator (12) for a limit switch (16). The worm shaft (4) is spring loaded against the direction, in which the torque exerted by the load being lifted on the worm wheel (7), reacts on the worm (5). A plate spring packet (10) is arranged between the housing (2) and the worm (5).</p> |
