    摘要： A retention assembly (50) for interconnecting first and second rotating components (24, 36) in a gas turbine engine (10). The second component (36) includes an engagement portion (70) defining protrusions (74) circumferentially spaced apart and extending axially therefrom. A threaded fastener (80) axially retains the second rotating component (36) to the first (24) and has key-receiving slots (86) and a circumferentially-extending groove (87). A key washer (90) is mounted to the fastener (80) and defines first and second axial surfaces (93, 94). The key washer (90) has a first set of keys (95) extending radially inwardly from a radially inner surface (91) and received within the key-receiving slots (86) and a second set of keys (97) extending from the second axial surface (94). A retaining ring (100) is disposed within the groove (87), is radially retained by the protrusions (74) extending axially from the second component (36), is axially retained between the second set of keys (97) and the second axial surface (94), and is radially spaced apart from the second set of keys (97) to define a radial gap (110) therebetween.
