摘　　要：通过对同一压力速度(PV)值下超高相对分子质量聚乙烯(PE-UHMW)的摩擦学性能研究,探讨PE-UHMW应用于电梯靴衬的影响因素。以PE-UHMW和45#钢为摩擦副,在MMW-1A摩擦磨损试验机上测量摩擦副在微量油工况和同一PV值下的摩擦因数和工作温度,并计算PE-UHMW磨损量。结果表明,在微量油润滑下,随着试验时间的延长,PE-UHMW的摩擦因数和工作温度分别经历了先降低后平缓和先急剧上升后平缓增加的变化,但在整个过程中PE-UHMW没有磨损;在同一PV值下,摩擦因数和工作温度均经历了波动式变化;随压力的增加,摩擦因数和工作温度的波动程度依次经历了较小、剧烈和平缓的变化。The effect parameters on tribological properties of PE-UHMW when used in shoe hnmg of the elevator system were studied. On an MMW-1A frictional rig, under the condition of minimum oil supply, at same pressure-velocity product （PV） and temperature, the friction coefficient between PE-UHMW and 45 steel and the mass loss of PE-UHMW were measured. With increasing wearing time, the friction coefficient first declined sharply, then became stable; the temperature increased first sharply and then slowly. The mass loss of PE-UHMW was zero during the whole experiment. For the same PV product value, both friction coefficient and temperature fluctuated, however, the amplitude of fluctuating became smaller with increasing pres- sure.
