A drive device includes an electric drive motor, a housing with a housing cover, at least one shaft that is powered by the drive motor and compensating element(s) for compensating the axial play of the shaft. The compensating elements include at least one axially elastic, deformable elastomer element having at least one contact surface. The contact surface(s) has a PTFE, PET or corresponding coating.

Drive device with anti-lash mechanism

A drive device includes an electric drive motor, a housing, at least one shaft which is driven by the drive motor, and a compensating member for compensating the axial clearance of the shaft. A spring ring disk, which can be expanded radially counter to an elastic force and has two stopping surfaces radially extending towards each other on the axis of the shaft in the form of a wedge, is arranged on the shaft as the compensating member. The shaft has a ring-shaped projection which matches one of stopping surfaces and the housing has an annular collar which matches the other stopping surface. The spring ring disc is pre-tensed and arranged in between the projection and the annular collar.
