Occurrence of periodic self-rotation of an orbiting scroll in scroll compressors having orbital mechanisms composed of a ball coupling and an eccentric bushing was indicated in our previous paper. This paper investigated successively the self-rotational motion of the orbiting scroll in detail. Complex motion of the orbiting scroll and the eccentric bushing was analyzed theoretically based on equations of motion about them. The motion was also measured experimentally with an optical method by changing operating pressure and magnitude of clearance at the ball coupling of the compressor. As a result, positive and negative self-rotation of the orbiting scroll during one revolution of the compressor was clearly demonstrated and the tendency was supported by the theoretical analysis.
