Abstract
A method and apparatus for detuning the natural frequency of a rotatable part, which is rotatably disposed in the shaft bearing, and in the case of which the axis of rotation of the rotatable part is arranged axially identically with the axis of rotation of the shaft bearing, as well as to a correspondingly tunable rotatable part. For compensating an axial play and/or a disturbing sound effect, the clamping conditions are changed by a reversible change of the axial course and/or of the axial contact pressure of an axial adjusting unit onto the rotatable part, the axial adjusting unit being manufactured of a piezoelectrically active material.
