摘要
基于Adams软件建立了考虑润滑作用的高速圆柱滚子轴承动力学模型,采用正交试验法对轴承结构参数进行了多目标优化设计,研究了不同工况及轴承结构参数对轴承保持架动态特性的影响。结果显示:内圈转速对保持架打滑率的影响最大,引导间隙对保持架打滑率的影响最小;引导间隙对保持架运转稳定性的影响最大,滚子个数对保持架运转稳定性的影响最小。经过优化设计获得了保持架打滑率及运转稳定性的轴承结构参数最佳组合。保持架打滑率随内圈转速及引导间隙的增加而增加,随径向载荷、滚子个数及径向游隙的增加而减小。保持架运转稳定性随内圈转速及引导间隙的增加而增强;随径向游隙的增加而降低;存在合理的径向载荷及滚子个数使保持架运转稳定性最好。
Based on Adams software,the dynamic model of high-speed cylindrical roller bearing considering lubrication was established,the multi-objective optimization design of bearing structure parameters were carried out by orthogonal test method,and the effect of different working conditions and bearing structure parameters on the dynamic characteristics of bearing cage were studied.The results show that the inner rotation speed has the greatest effect on the skid rate of cage,and the guide clearance has the least effect on the skid rate of cage.The effect of the guide clearance on the stability of cage is the greatest and the roller number on the stability of cage is the least.The optimal combination of cage skid rate and stability of bearing structure parameters was obtained by optimization design.The skid rate of cage increases with the increase of inner rotation speed and guide clearance,and decreases with the increase of radial load,roller number and radial clearance.The stability of cage increases with the raise of inner rotation speed and guide clearance,it decreases with the raise of radial clearance,there is a reasonable radial load and roller number make the cage the best stability.
