摘要

铜基粉末冶金摩擦副广泛应用于液黏传动,为了研究摩擦副的摩擦特性,应用MM-Ⅲ型摩擦磨损性能试验机对铜基粉末冶金摩擦副不同工况下的摩擦因数进行了测试,分析了相对转速、接触比压、温度对摩擦因数的影响。结果表明,摩擦因数随着相对转速的变化与斯特里贝克曲线相似,摩擦因数先急剧下降,后缓慢上升;随着摩擦副接触比压的增加,油膜黏性剪切作用减小,接触摩擦因数随着比压的增加逐渐降低;同时,接触摩擦因数受温度的影响较小。因此,应用摩擦磨损试验机可以得到铜基粉末冶金摩擦副摩擦因数随相对转速、温度和比压的变化规律,为混合摩擦转矩模型建立和液黏传动调速稳定性研究提供理论依据。

Abstract

The copper-based powder metallurgy friction pairs are widely used in hydro-viscous drive. In order to research the frictional characteristics of friction pairs,the frictional coefficient under different working conditions is tested by using MM-Ⅲ friction and wear performance tester. The influences of relative rotational speed,contact pressure and temperature on frictional coefficient are analyzed. The results show that the frictional coefficient changing with relative rotational speed is similar to the Stribeck curve,which drops sharply first and then rises slowly. With the increase of the contact pressure,the viscous shear effect of oil film become lower,and the contact frictional coefficient gradually decreases. In addition,temperature has a small effect on contact frictional coefficient. Therefore,using MM-Ⅲ friction and wear performance tester,the variation of frictional coefficient of copper-based powder metallurgy friction pairs with relative rotational speed,contact pressure and temperature can be obtained,which provides a theoretical basis for the study on mixed friction torque model and speed regulation stability of hydro-viscous drive.
