【Abstract】 Geometric, kinetic, and lifetime analysis of anti rotation mechanism with thrust ball bearing is conducted, which is commonly employed in the scroll compressor of automotive air conditioning system, and its wear during later stage’s operation is also analysed quantitatively. It is pointed out that, in the case of having radial flexible mechanism, the wear between anti rotation mechanism and scroll wrap exhibits synchronism and self compensation. Otherwise slight rotation would take place with that mechanism and orbiting scroll, resulting in asymmetric pressure within compression chamber pair and radial leakage.更多还原
