ABSTRACT:
A wobble plate compressor includes a non-rotary socket plate mounted on a journal of a rotary drive plate. The drive plate includes a bushing and a needle-type thrust bearing to accommodate relative rotary movement between the plates. The socket plate and drive plate are retained together by an assembly including a square-edged annular channel formed in a recessed journal, a thrust washer for engaging the journal and the bushing and a dished retaining ring. The dished retaining ring also includes square edges mating with the adjacent sides of the channel. The retaining ring engages the thrust washer so as to provide a preload force to seat the washer on the journal and for biasing the socket plate against the thrust bearing. The retaining ring is characterized by a three degree dish angle when compressed between two flat parallel surfaces with an applied load of 30N.
