Abstract
A rotor assembly comprises a first body and a second body extending about a rotation axis. The first body has an inner surface, a seat surrounded by the inner surface, and a groove extending circumferentially into the inner surface. The second body has an outer surface surrounded by the inner surface. An annular gap is defined radially between the inner surface and the outer surface and axially between the seat and the groove. A locking washer is mounted in anti-rotational engagement with the inner surface and the outer surface relative to the rotation axis. A split ring is disposed in the annular gap. The split ring is resiliently expandable radially outwardly under centrifugal load such that expanding the split ring radially against the groove axially deflects the split ring toward the seat relative to the first body and to the second body so as to axially load the locking washer against the seat.
