Abstract
A damper unit (1) composed of two parts (2, 3) which are connected to rotate with one another and between which an axially elastic element (7) is disposed. Such damper units are used particularly for axial damping and for compensating slight axial misalignments of shafts in drive trains. To improve such damper units, particularly with respect to their external diameters, the axially acting energy storage device is compressed by a rotational movement produced by threads upon axial loading of the two parts.
