Evaluation of Wear and Failure of Gate Bottom Pivot Friction Pairs under Grease Lubrication

Abstract

Abstract: Friction and wear testing machine was used to obtain tribological properties of QAL9-4/40Cr and ZCuAl8Mn13Fe3/40Cr under different contact stresses under conditions of grease lubrication. Grey system theory GM(1,1) model which evaluated allowable wear amounts of wear failure was applied. When actual contact stresses of the two copper-based friction pairs are below allowable stresses under low-speed and heavy-load conditions, wear patterns are mainly plough-cut; wear amount increases and friction coefficient decreases, when the contact stresses increase. On the contrary, the wear patterns are mainly sticky, and the wear rate and friction coefficient increase sharply. Under low-speed and heavy-load, QAL9-4/40Cr has better wear resistance when two copper base friction pairs are subjected to the same contact stresses. Coincidence of the theoretical predicts and the test results attend 95%.

摘要： 采用摩擦磨损试验机，获得了QAL9-4/40Cr和ZCuAl8Mn13Fe3/40Cr两种闸门底枢摩擦副在不同接触应力的脂润滑条件下的摩擦学特性，并运用灰色系统理论GM（1，1）模型对其达到许用磨损量的磨损失效进行了评价。低速重载条件下，两种摩擦副的实际接触应力在许用应力之下时，其磨损形式均以犁切为主，且磨损量随接触应力的增大而增大，摩擦因数随着接触应力的增大而减小；反之，其磨损形式均以黏着为主，且磨损速度、摩擦因数均会急剧增加。受同一接触应力作用时，QAL9-4/40Cr具有更好的耐磨性。理论模型对磨损失效的预测结果与实测值吻合度达到95%。
