ABSTRACT:
An outer race carrier (52) is constructed for receiving an outer race (26) of an antifriction bearing assembly (10). The carrier (52) in turn is slidably fitted in an opening (57) of a support wall to accommodate slight axial movements of a shaft (14). A plurality of longitudinal splines (54) on the carrier are disposed to be fitted into matching slots (56) in the opening (57). A deadband gap (60) is provided between sides of the splines and slots, with a radial gap (62) at ends of the splines and slots and a gap (59) between the splines and slots sized larger than the deadband gap. With this construction, operational distortions (slope) of the support wall are accommodated by the larger radial gaps (62, 59) while the deadband gaps (60) maintain a relatively high springrate of the housing. Additionally, side loads applied to the shaft are distributed between sides of the splines and slots, distributing such loads over a larger surface area than a race carrier (28) of the prior art.
