Abstract:
1. A drum drive comprising an essentially cylindrical drum that delimits an internal space intended for receiving an electromotor for producing a rotating movement of the drum about a fixed shaft ( 7 ) intended for being fixedly mounted on supporting elements, characterised in that the drum drive includes a stator cap ( 3 ) that is fixed to the cylindrical drum and turnably journalled about the fixed shaft ( 7 ); that the motor comprises at least one resilient damping device ( 10 ) that is connected to the fixed shaft ( 7 ) and to the stator cap ( 3 ) and extends radially from the fixed 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 cap ( 3 ) to rotate about the fixed shaft ( 7 ).
