Abstract
A retainer assembly (10) comprises a retainer member (24) and a spring (36). The spring (36) works in combination with a conical surface (34) on the hub (12) and a conical surface (28) on the retainer member (24). Depending upon magnitudes of defined angles A and W, the assembly (10) resists any axial force (42) that may act to disengage the disk (14) from the hub (12). The angles A and W are variable so long as a coefficient of friction .mu. between the conical surface (34) or the conical surface (28) and the ring (36) is greater than the tangent of one half the angle W.
