Abstract
The invention relates to a drum drive that delimits an interior space intended for receiving an electromotor for producing a rotating movement of the drum. The electromotor comprises a stator, shell and stator cap. The stator is turnably journalled about the shaft (7), wherein the drive comprises at least one damping device (10) connected to the shaft (7) and to the stator, and extending radially from the shaft in a plane that is essentially at right angles thereto; and wherein the damping device (10) is configured for absorbing forces that strive to rotate the stator about the shaft.
Claims14
A drum drive comprising an essentially cylindrical drum that delimits an internal space intended for receiving an electromotor with a stator and a rotor for producing a rotating movement of the drum about a shaft (7) intended for being fixedly mounted on supporting elements, characterised in that the stator is turnably journalled about the shaft (7);
- that the motor comprises at least one resilient damping device (10) that is connected to the shaft (7) and to the stator and extends radially from the shaft (7) in a plane essentially at right angles thereto;
- and that the damping device (10) is intended for absorbing forces that strive to cause the stator to rotate about the shaft (7).
