Shaft assembly for a gas turbine engine

摘要

A shaft assembly (10) includes a shaft (12), a nut (40), a nut lock ring (42) and a tubular nut support ring (44). The nut (40) includes a nut base (46) mounted on the shaft (12), and a plurality of protrusions (48) that extend radially out from the nut base (46). Adjacent protrusions (48) are circumferentially separated by a gap (58). The nut lock ring (42) includes a tubular ring base (60) connected axially between a plurality of first lock tabs (62) and a plurality of second lock tabs (64). The ring base (60) is disposed on the nut base (46). Each first lock tab (62) extends radially inward through a respective notch (32) provided on an end of the shaft (12). Each second lock tab (64) extends axially through a respective one of the gaps (58). The nut support ring (44) is disposed on the ring base (60).
