Vibration damper assembly for the buckets of a turbine

Vibration damper assembly for the buckets of a turbine

A damper pin (40) is disposed between adjacent buckets of a turbine rotor. A first bucket has circumferentially extending supports (24) defining a pair of axially spaced surfaces on which a damper pin rests in a cold condition of the turbine. The adjacent bucket is undercut (30) adjacent its platfor...

description A damper pin (40) is disposed between adjacent buckets of a turbine rotor. A first bucket has circumferentially extending supports (24) defining a pair of axially spaced surfaces on which a damper pin rests in a cold condition of the turbine. The adjacent bucket is undercut (30) adjacent its platform to provide an angled surface (32) overlying a generally correspondingly angled surface of the damper pin. The damper pin fits slightly loose within the recess and, upon turbine rotation at speed, the angled surfaces of the damper pin and recess cooperate to bias the damper pin against the first bucket whereby the damper pin engages both buckets and dissipates vibratory action.
