Gas turbine engine synchronizing ring bumper

摘要

A synchronizing assembly (31) for a gas turbine engine (10) includes a synchronizing ring (34). A composite bumper (38) is secured to the synchronizing ring (34) by a fastener (50). A structure is arranged between the bumper (38) and the synchronizing ring (34). The fastener (50) applies a first load through the structure to the synchronizing ring (34) and a second load through the bumper (38). The second load is substantially less than the first load. In one example, the structure includes a bushing (48) that extends through a hole (44) in the bumper (38). The bushing (48) is proud of the hole (44) on the other side of the bumper (38) and protrudes into the counterbore (66). The fastener (50) is arranged in the bushing (48) and applies a clamping load through the bushing (48) to secure the bumper (38) to the synchronizing ring (34).
