车辆行星轮轴向滑动支承组合沟槽润滑性能比较分析
|
摘要
在之前学者对单一微织构槽润滑特性的研究基础上,对具有代表意义的三角形槽和圆弧形槽进行同型和非同型的双槽组合研究,研究目的是通过对两类组合槽形润滑性能的比较分析,以得知哪种织构组合形式用于支撑端面沟槽设计时能更好的实现行星轮与滑动支撑表面摩擦力的最小化,以最大化增加其使用寿命。研究方法是通过在与行星轮接触的滑动支撑端面加工微米级的沟槽引入流体动压润滑机制实现行星轮与滑动支撑表面的分离以减小两者之间的摩擦力。通过对两类组合沟槽比较分析本文得出的结论为:总体性能而言,三角同型组合槽优于圆弧组合槽;三角与圆弧组合成的非同型沟槽其综合性能介于三角同型组合槽与圆弧同型组合槽之间。如果着重某一方面的性能且同时考虑加工难易程度的话,则推荐优先选用符合条件的同型组合沟槽。
Based on the previous researches on the lubrication characteristics of single micro-grooves, this paper performed the same type and non-same double-slot combination on the triangular grooves and circular grooves.The purpose of the research is to lubricate the two types of combined grooves. The comparative analysis of the performance to know which kind of texture combination is used to support the end groove design can better minimize the friction between the planet wheel and the sliding support surface to maximize the service life. The research method is to reduce the friction between the planetary wheel and the sliding support surface by introducing a fluid dynamic pressure lubrication mechanism by processing a micro-scale groove on the sliding support end surface in contact with the planetary gear. By comparing the two types of combined grooves, the conclusions drawn from this paper are: the overall performance, the triangular identical groove is better than the circular combination groove; the combination of triangular and circular arcs has a comprehensive performance of triangular similarity. The combination groove is in the same shape as the circular arc combination groove. If you focus on the performance of a certain aspect and consider the ease of processing at the same time, it is recommended to use the same type of combined groove.
