STACKED WHEEL ASSEMBLY FOR A TURBINE SYSTEM AND METHOD OF ASSEMBLING

摘要

A stacked wheel assembly for a turbine system includes a plurality of wheels. A stud includes a forward end having a circumferential surface with at least one relatively planar portion and a first groove extending circumferentially around at least a portion of the circumferential surface. A first nut is disposed proximate a forward face of one of the plurality of wheels to receive the forward end of the stud. A resilient arcuate member is configured to fittingly reside within the first groove. A lock plate having at least one slotted region is disposed proximate an outer surface of the lock plate to fittingly engage at least one lug disposed on a forward region of the first nut for rotationally retaining the stud and a second groove is disposed within an inner surface of the lock plate to receive the resilient arcuate member for axially retaining the lock plate.
