Turbine bucket damper pin

摘要

A damper pin for a bucket damper slot in a turbine includes slot insertion ends (12) shaped to fit into the bucket damper slot, and at least a first scallop section (14) formed or machined between the slot insertion ends and shaped to receive a bucket shank pocket radial contour at bucket Hi-C. A second scallop section (16) may also be formed or machined diametrically opposed and anti-symmetrical to the first scallop section between the slot insertion ends.
