More Information
Summary:The proposed invention relates to a rotating element (1) for a rotating machine, in particular for a turbine machine, being provided with a vibration damper (2-5) for vibrations of the rotating element during operation of the machine, wherein the vibration damper (2-5) comprises a closed cavity (2) in the body of the rotating element, wherein in said closed cavity (2) there is located a movable solid damping body (3) as well as a damping medium (4), wherein said damping medium (4) 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.
