TRAPPED SPRING BALANCE WEIGHT AND ROTOR ASSEMBLY

摘要

A balance weight for a turbine rotor includes: a block-like centerbody (62); a pair of resilient spring arms (64) extending laterally from opposite sides of the centerbody, the centerbody and the spring arms collectively defining an arcuate shape; at least one locating structure extending from a radially outer surface of the balance weight; and a limit tab (170, 271) extending radially inward from a distal end of each of the spring arms.
