In scroll compressors having orbiting mechanisms composed of a ball coupling and an eccentric bushing, there is a possibility of self-rotational motion of an orbiting scroll. The motion will induce leakage loss in the compressor, which degrades the performance of the compressor. We analyzed theoretically the self-rotational motion of the orbiting scroll by taking account of leakage flow through clearances originating due to the motion and a frictional force acting on a contact point between the two wraps. The effect of the motion on the compressor performance was also investigated experimentally. It was clarified that with increasing clearance at the ball coupling, the self-rotational angle of the orbiting scroll becomes large and volumetric effiiciency of the compressor decreases while compression torque of the compressor increases.
