SCROLL COMPRESSOR AND METHOD FOR MANUFACTURING AN OLDHAM RING THEREFOR

摘要

A SCROLL COMPRESSOR HAVING AN EXTENDED LIFE DUE TO THE SUPPORT STRUCTURE (10) FOR THE ORBITING SCROLL (3), EVEN WHEN USING A CHLORINE-FREE SUBSTITUTION REFRIGERANT. THE SUPPORT STRUCTURE (10) INCLUDES AN OLDHAM RING (6) FOR SUPPORTING AN ORBITING SCROLL (3) SO AS TO ALLOW THE ORBITING SCROLL (3) MORE ORBITING MOTION WITHOUT ROTATING ABOUT A FIXING SCROLL (4). THE OLDHAM RING (6) IS FORMED OF A DIFFERENT MATERIAL FROM BOTH A FIXING MEMBER (7) AND THE ORBITING SCROLL (3). HENCE, IF A BOUNDARY LUBRICATION STATE OCCURS IN MUTUALLY SLIDING PARTS, ONLY SLIDING BETWEEN DIFFERENT MATERIALS OCCURS, AND MUTUAL ADHESION IN THE PORTION OF THE BOUNDARY LUBRICATION STATE IS AVOIDED. AS A RESULT, THE SHORTENING OF THE LIFE DUE TO THE WEARING OF THE SUPPORT STRUCTURE (10) OF THE ORBITING SCROLL (3) IS PREVENTED. (FIG. 3)
