论述了计及表面粗糙度、弹性变形、热效应、润滑油非牛顿性、轴颈倾斜、内燃机工况、轴承结构参数、供油状况等影响因素的内燃机曲轴轴承润滑性能研究的现状和进展,讨论并展望了内燃机曲轴轴承润滑影响因素研究中有待解决的一些问题。
The current state of the lubrication performance of crankshaft bearing in internal combustion engine was dis- cussed considering the surface roughness, elastic deformation, thermal effect, non-Newton performance of lubricating oil, jour- nal misalignment, engine operating condition, structural parameters of bearing and inlet oil condition. The problems need to be solved in future research such as influence factors of lubrication in crankshaft bearing are also forecast and analyzed.
