A worm drive includes a rotatably mounted worm shaft, and a device for compensating an unwanted axial backlash of the worm shaft. The device for compensating the unwanted axial backlash of the worm shaft includes two pressure bodies between which the worm shaft is clamped in the axial direction by a diaphragm spring device. The diaphragm spring is assigned to one of the pressure bodies.

Worm drive

A drive apparatus includes a housing, an electric motor arranged in the housing, and a worm gear mechanism arranged in the housing. The worm gear mechanism includes a worm gear arranged on a rotor shaft of the electric motor and a gearwheel in engagement with the worm gear and fixedly connected to an output shaft so as to rotate with the output shaft. The electric motor is axially mounted in the housing with one axial end via a stop element and with the opposite axial end via an axial clamping element. The axial clamping element has a spring element, a separate floating holding element, and a separate elastomer element. The holding element is arranged axially between the spring element and the elastomer element.
