ABSTRACT:
A rotating machine comprises a housing defining a generally cylindrical bearing pocket and defining an interior and exterior. The machine also includes a bearing retainer having a generally cylindrical sleeve portion retained in the bearing pocket and a bearing having an outer race and an inner race, the outer race affixed within the cylindrical sleeve portion. The machine further has a rotating member mounted on a shaft for rotation therewith, the shaft having a portion affixed within the inner race of the bearing. In one embodiment, the bearing retainer includes anti-rotation keying projections the bearing pocket includes complementary depressions for the keying projections. The keying projections cooperate with the complementary depressions to prevent rotation of the bearing retainer with respect to the bearing pocket. In another embodiment, a cap is affixed to the bearing retainer to substantially prevent contamination from reaching the bearing from the exterior.
