Abstract
An actuator with an electric motor which drives an activation element, such as a rotatable arm or a longitudinally movable rod, via a transmission. The transmission has at least two transmission stages, the first one being formed by a worm drive, the second one being formed by a crown and bevel wheel ( ), the bevel wheel ( ) being driven by the worm wheel ( ), and the crown wheel ( ) having a power take-off ( ). The transmission may readily be formed so that the axis of the crown wheel ( ) is in direct extension of the worm ( ). A relatively compact transmission with a high gearing may be achieved hereby, and with worm wheel as well as crown and bevel wheel of plastics the transmission is also comparatively noiseless.
