OLDHAMRING OIL SUPPLY STRUCTURE OF SCROLL COMPRESSOR, PARTICULARLY REGARDING TO PREVENTING LOWERING OF COMPRESSOR AND REDUCTION OF LIFE SPAN BY STABILIZING ORBITING OF ORBITING SCROLL

摘要

PURPOSE: An oldhamring oil supply structure of a scroll compressor is provided to prevent lowering of a compressor and reduction of the life span by stabilizing orbiting of an orbiting scroll and preventing abrasion of an oldhamring. CONSTITUTION: A main frame(11) is fixed at a casing filled with a certain amount of oil. A fixed scroll(12) is fixed at the main frame. An orbiting scroll(13) is engaged with the fixed scroll for forming a pair of compression chambers continuously move. A driving shaft(14) is concentrically combined with a boss part(13b) of the orbiting scroll for transmitting rotary force of a driving motor to the orbiting scroll. An oldhamring(15) is interposed between the main frame and the orbiting scroll for making the orbiting scroll orbit. An oil guide groove(11d) is formed at the main frame for inducing oil scattered at an upper end of the driving shaft to a sliding part between the oldhamring and the frame.
