倒角参数对滚子弹流润滑性能的影响研究
Study on Influence of Crowning Parameters on EHL Performance of Cylindrical Rollers
摘要
Abstract
Rollers are usually crowned on their ends in engineering, and the crowning parameters include crowning length and crowning radius. With the multilevel method and Eyring theological model, the effects of the crowning parameters on the lubrication performances were studied. It is concluded that the minimum filmthickness may locate at either the crowning beginning place or the roller edge. When the minimum filmthickness located at the roller edge, lubrication failure would appear. The effects of the crown length and crown radius on the lubrication performance were studied. It shows that the crowning parameters should be designed according to EHL calculation on the basis of working conditions to optimize the lubrication conditions and load distributions and realize full film lubrication.关键词
