Abstract
The present invention proposes a shaft assembly mechanism for a scroll compressor. An eccentric portion is installed at the top end of an eccentric shaft. A ring is lagged connectedly to the eccentric portion. A homocentrically arranged through hole is installed in the ring. The ring is lagged connectedly to the eccentric portion of the eccentric shaft via the through hole. A fixing hole is disposed at the bottom end of an orbiting scroll. A bushing is installed fixedly in the fixing hole. A through hole is installed in the bushing. A spiral oil groove for addition of lubricating oil is installed on the inner wall of the through hole of the bushing. The through hole of the bushing is lagged connectedly to the outer side of the ring. A shaft assembly mechanism of low noise, flexible assembly process, and easily controlled accuracy can thus be formed.
