CONSTANT-VELOCITY JOINT AND SWING SWASH PLATE COMPRESSOR

PROBLEM TO BE SOLVED: To provide a swing swash plate compressor, keeping a lubrication state of a sliding part without increase in bearing of the sliding part, and using a constant-velocity joint with improved reliability as a detent mechanism. SOLUTION: A constant-velocity joint 7 is constituted of an inner ring 73, an outer ring 71, balls a cage 72. Oil retaining grooves 75 are disposed at an approximately center part in an axial direction of a sphere sliding part as non-sliding part between the inner ring and the cage of the constant-velocity joint or between the cage and the outer ring, so as to keep a good sliding condition between the cage and the inner ring/outer ring. The constant-velocity joint is adopted as a detent mechanism of a swing swash plate compressor 100, the outer ring 71 is fitted and fixed to a wobble plate 6, and the inner ring 73 is movably supported by a center shaft 8. Therefore, the compressor becomes highly reliable. COPYRIGHT: (C)2007,JPO&INPIT
