Abstract

A vibration dampening system (120) is provided for a turbine nozzle (112) or blade (114). A body opening (160) extends through the turbine nozzle (112) or blade (114), e.g., through the airfoil (134) among potentially other parts of the nozzle or blade. A vibration dampening system (120) includes a plurality of stacked damper pins (174) within the body opening (160). The damper pins (174) include an outer body (176) having defined therein an inner opening (178) and a plurality of side openings (180) extending from the inner opening (178) through an outer surface (182) of the outer body (176), and an inner body (190) is nested and movable within the inner opening (178) of the outer body (176). The inner body (190) includes a first portion (192) including a plurality of arms (194), each arm extending through a respective side opening (180) of the plurality of side openings (180) of the outer body (176). The end surfaces (184, 186) of the damper pins (174) and the two bodies (176, 190) frictionally engage to dampen vibration.
