衬套与活塞销轴线不平行润滑分析

Analysis of Lubrication of the Non Parallel Bushing and Piston Pin

基于平均流量模型及微凸体接触理论,建立考虑表面粗糙度的衬套与活塞销轴线不平行润滑模型,对其进行润滑仿真计算分析。结果表明:两轴线同面倾斜时,对润滑性能影响微弱,轴线异面倾斜时对润滑影响较大,对衬套的润滑分析不可忽略其影响。

Based on the average flow model and asperity contact theory, a lubrication model considering the surface roughness and the inclination of the shaft neck is set up, calculation and analysis of beating lubrication performance. The results show that： the lubrication performance is weak when the two axis is tilted, and the axis of the different side has a greater impact on the lubrication, the lubrication analysis of the bushing can not neglect the influence of the shaft neck tilt.
