摘要

将三叉杆联轴器圆柱滚子与滑块槽之间的运动简化为圆柱与无限大平面之间的运动，结合联轴器运转过程中的非稳态效应，建立时变挤压效应下线接触热弹流脂润滑的数值计算模型。采用多重网格法求解得到压力、膜厚和润滑油膜平均温升等润滑指标的瞬态解，并与稳态值进行对比分析。结果表明，当时变效应处于低频状态下，润滑油膜特性的瞬态解与稳态解相差不大，但处于高频状态下时，油膜厚度整体小于稳态解，且高频时的温升现象尤其明显；一个载荷冲击周期内，高频解与低频解的分布基本相同，但高频时的膜厚明显低于低频解。

Abstract

The motion between the cylindrical roller and the slider groove of the tripod coupling is simplified as the motion between the cylinder and the infinite plane. With consideration of the unsteady state effect and time-varying squeeze effect in the running process of coupling，the numerical calculation model of linear contact thermal elastohydrodynamic grease lubrication is established. The transient solutions of lubrication parameters such as film pressure，film thickness and average temperature rise of lubricating oil film are obtained by using multi-grid method. The transient solutions are compared with the steady-state values. The results show that the transient solution and the steady solution of lubricating oil film characteristics are not much different when the variable effect is in the low frequency state. While in the high frequency state，the oil film thickness is smaller than the steady solution as a whole，and the temperature rise is particularly obvious. The distributions of high-frequency solution and low-frequency solution are almost same while the film thickness of high-frequency state is lower significantly than that of low-frequency state in a period of impact load.
