The invention relates to a belt pulley damper for damping torsional vibrations of a drive shaft, comprising a belt pulley for driving a traction means, in particular a traction belt, and an input flange that can be connected to the drive shaft in a rotationally fixed manner, wherein the input flange has at least one fastening element, in particular an opening, for connecting the input flange to the drive shaft. In addition, a torsional vibration damper, in particular a decoupler for torsional vibrations, is provided in order to transfer a torque applied by means of the input flange to the belt pulley. A bearing for supporting the belt pulley on the input flange is formed between the belt pulley and the input flange. According to the invention, the bearing is arranged between the fastening element and a rotational axis of the input flange in the radial direction. Thus a hub connected to the drive shaft can be spared and the belt pulley damper can be produced accordingly small so as to save available space. Thus a belt pulley damper is created, by means of which a simplified design and low production costs can be made possible. |
