Abstract

The invention relates to an oscillation damper (1) for oscillations superimposing a rotating movement about a rotational axis (3). Said damper comprises at least one rigid pendulum (4) mounted in such a way that it swings about a pendulum axis (5), the pendulum axis (5) swinging about the rotational axis (3) with the rotating movement, at a fixed distance (R) from the rotational axis (3). The mass distribution of the pendulum (4) about the pendulum axis (5) is such that the inherent frequency of the movement of the pendulum (4) about the pendulum axis (5) in the centrifugal field is the same as the rotational frequency (2) of the rotating movement (2) about the rotational axis (3) as a result of the rotating movement (2) about the rotational axis (3).
