Analysis and experimental study on influencing factors of sprag windmill wear of overrunning clutch
An overrunning clutch is taken as the research object.Based on force analysis and Archard model,the factors that may affect the sprag windmill wear rate are obtained,and the difference of sprag wear rate under different working conditions are compared by component-level wear test.The results show that all factors have influence on the wear rate,but the signifi-cance and trend of the influence are different.Grey correlation analysis is used to analyze the relationship of the factors af-fecting the sprag wear rate,and the results show that the order of the factors is:oil flow＞relative sliding speed＞friction mo-ment.
