摘　　要：针对钢蜗轮传动的耐磨性能开展研究,设计一种适用于瞬时线接触滑动摩擦的销盘试样,对比分析几种典型成品油的减摩抗磨性能;开展微观啮合参数与滑动摩擦因数的相关性试验分析,定量研究载荷和滑动速度对传动副摩擦因数的影响。结果表明,线接触滑动摩擦试验能充分模拟平面蜗轮副任意瞬时的摩擦学系统;车辆齿轮油GL-5的减摩抗磨性能较好,较大的诱导法曲率半径和润滑角可以降低摩擦因数,该试验为钢制平面蜗轮传动的参数选择及优化设计提供了有利的依据。In order to research the wear - resistant performance of steel planar worm gear, a kind of pin disc sample suitable for instantaneous line contact sliding friction is designed, the antifriction and wear - resist- ant performance of several typical oil is contrasted and analyzed. The correlation experimental analysis of the microscopic meshing parameter and sliding friction coefficient is carried out, the influence of load and sliding speed on the friction coefficient of transmission is quantitatively researched. The result shows that the tribology system of every point on teeth of planar worm gear pairs can be simulated successfully by line contact sliding friction test. The antifriction and wear- resistant performances of vehicle gear oil GL- 5 is better, the friction coefficient decreases with the induced normal curvature radius and lubrication angle increasing. A favorable ba- sis for the parameter selection and optimization design of steel planar worm gear is provided by the test.
