ABSTRACT:
A vibration dampener adapts to different speeds of rotation. The device comprises a drive collar (1) and several inertial masses (2). The collar rotates around a central axis (3) and the inertial masses pivot around peripheral axes along the direction of rotation. Each inertial mass is secured to the collar by two bolts (5). The bolts, which extend parallel the central axis, are distributed around the circumference of the collar, and roll back and forth along arcs (6). The arcs are concave toward the central axis in the vicinity of the collar and concave in the opposite direction in the vicinity of the inertial masses. The bolts extend through a guide (7) toward the sides facing away from the associated arcs.
