Abstract

A tuned mass vibration damper for damping a vibration component of a rotational movement, has at least one guide component part configured to movably guide the damper masses such that the damper masses are offset along a circumferential direction, and a dimensionally stable spacer component part that is rotatable relative to the guide component part and which has a positive engagement connection with clearance with the damper masses that are configured such that, starting from a center position of the damper masses with respect to the spacer component part, when one of the damper masses executes an oscillation which overcomes a clearance in the connections of two of the damper masses with respect to the spacer component part, the spacer component part is rotated along the circumferential direction such that it drives the other damper mass of the two damper masses along the circumferential direction.
