Abstract

A device for damping torsional vibrations has two elements that are rotatable relative to each other. One of the elements is connected to a motor, and the other element is connected to a gear box. A torsional vibration damper with energy accumulators is interposed between the elements to counteract a relative rotation between them. At least one of the elements is configured as a disc-like sheet metal part in which circumferentially extending mountings or pockets are formed to receive the energy accumulators. Press-formed support areas in the sheet metal part delimit the pockets in the circumferential direction and serve to introduce biasing forces into the energy accumulators. Impressed in the sheet metal part are circumferential grooves extending over at least part of the length of each pocket between the press-formed support areas.
