METHOD AND APPARATUS FOR BALANCING TURBINE ROTORS |
摘要 |
A method for balancing a gas turbine rotor includes providing a gas turbine rotor including a plurality of turbine blades (50), wherein at least one turbine blade includes a blade tip shroud (68) that includes a leading edge (74) and a trailing edg e (78) that is opposite the leading edge, and coupling a balance clip (100) to the at least one turbine blade. The balance clip includes a first portion (102) having a first length (104) that enables the clip to extend between the tip shroud leading and trailing edges and includes a first hook (114) that is configured to couple to the tip shroud leading edge, a second portion (106) having a second length (108) that is shorter than the first length, such that the second portion extends only partially from at least on e of the tip shroud trailing and leading edges towards the opposite shroud edge, and a second hook that extends between the first and second portions and is configured to couple to at least one of the tip shroud leading and trailing edges.
