| 摘 要： | 用MPV－200型摩擦磨损试验机测定了超高分子量聚乙烯（简称UHMW－PE）塑料合金轴承分别在水润滑和干摩擦条件下的摩擦学性能，考察了载荷、速度、运行时间等对塑料合金轴承的摩擦学性能的影响，结果表明：摩擦系数用水润滑的小，干摩擦下的大；但磨损率用水润滑时大，干摩擦时小。对磨损机理进行了系统的分析，为兼合金轴承的实际应用提供理论依据。

| Abstract: | Ultra High Molecular Weight Polyethylene (UHMW-PE) is a kind of high anti-wear engineering plastic with many excellent physical and mechanical performances. It has been widely applied in the field of mechanism such as bearing and pump. Effect of load, speed, time on friction and wear properties of Ultra High Molecular Weight Polyethylene(UHMW-PE)plastic alloy bearings under different Lubricating Condition are studied by using MPV-200 model friction and wear testing machine. The test results show that water lubrication reduces the friction coefficient of bearings but increases the wear rate as compared with dry friction. At the same time, wear mechanisms are analyzed systemically. It provides a theoretic basic for practical application of plastic alloy bearings |
