REPAIR METHOD OF SPRING ASSEMBLIES IN STATOR CORE

摘要

PROBLEM TO BE SOLVED: To modify a welded interface between a U-plate and a spring bar to minimize crack development and propagation.SOLUTION: An embodiment comprises: a U-plate 54 that is fixed to a frame ring 56 of a stator frame; an attachment member 52 that is fixed to an outboard face of the U-plate, the attachment member 52 including a hole through the attachment member 52; a spring bar 64 with a hole that aligns with the hole in the attachment member 52; and a bolt 60 that passes through the hole in the attachment member 52 and the hole in the spring bar 64, where the bolt 60 is used to couple the attachment member 52 and the U-plate 54 to the spring bar 64.
