Patent abstract
A rotating element for a rotating machine, in particular for a turbine machine, is provided with a vibration damper for vibrations of the rotating element during operation of the machine. The vibration damper includes a closed cavity in the body of the rotating element. In the closed cavity there is located a movable solid damping body as well as a damping medium. The damping medium is based on a metal which is in liquid state at the operation temperature where damping is desired. It furthermore relates to turbo machines equipped with such rotating elements as well as to uses of liquid metal for such vibration dampers.
