Description

The authors were studying micro groove bearing using the copper-lead alloy that was used at the time of development, so report the results of the study. Ｗear test on engine test bench reveals optimal ratio of width to groove depth for micro groove bearing. The friction loss torque of properly designed micro groove bearings is slightly reduced compared to natural plain bearings. Authors thought that the upper limit of oil clearance could be reduced by that amount. Properly designed micro groove bearing endurance test showed no seizure or fatigue, and good wear results were obtained. The optimum groove size for micro groove bearings are groove depth of 2.5-4.5μｍ and groove width of 0.15-0.25mm.
