Oscillation damper for damping vibrations of shaft, has dampers and self-aligning bearing which are uniformly distributed around hub, such that damper natural frequency of oscillation around rotational axis is independent of pivot axis

摘要

The oscillation damper (1) has several dampers (2) which are mounted in the direction parallel to the rotating shaft in the hub (6). The dampers and the self-aligning bearing are uniformly distributed in the circumferential direction around the hub, such that the damper natural frequency of oscillation (8) around the rotational axis (3) is independent of the orientation of the pivot axis (9) in the circumferential direction about the rotational axis.
