摘要

中文摘要: 轴承滚道界面的润滑状态及接触力对轴承寿命的影响十分显著，为提高圆柱滚子轴承寿命，提出了在轴承外圈开槽填充弹性体的方法。采用有限元法计算了不同槽宽及丁晴橡胶、尼龙1010、硬铝合金和紫铜四种填充材料对轴承内滚道和滚子接触力的影响。在此基础上，建立了考虑圆柱滚子轴承真实表面粗糙度混合润滑数学模型，分析了不同转速下不同填充材料对轴承润滑性能的影响。结果表明：轴承外圈开槽并填充弹性体对轴承的润滑状态和接触力影响显著；最大受载滚子与内滚道的接触力随着填充材料弹性模量的减小而减小，采用丁晴橡胶和尼龙1010填充材料可明显增加滚子接触个数，有效降低接触力。转速的增加会使油膜变厚、摩擦系数、接触载荷比、接触面积比、最大接触应力减小，采用丁晴橡胶填充材料轴承润滑性能最好。

Abstract

Abstract:The effect of bearing raceway lubrication status and contact force on the service life of bearing is significant. In order to improve the service life of cylindrical roller bearing

one method is proposed that bearing outer is slotted and filled with elastomer. The effects of different pore size and four fillering materials with nitrile rubber

nylon-1010

hard aluminum alloys and red copper on the contact force between the inner ring raceway and rollers of bearing have been calculated with finite element method (FEM). A mixed lubrication model is established by considering the real surface roughness of cylindrical roller bearing

and the influence of different fillering materials on lubrication performance of bearing under different rotation speeds conditions has been obtained as well. The results show that the effect of bearing outer filled with elastomer on lubrication performance and contact force is significant. The contact force of the maximum force roller and inner ring raceway decreases with the decreasing of the elastic modulus of filler materials. And it is found that nitrile rubber and nylon-1010 can obviously increase the contacts number and effectively reduce the contact force. The increase in speed increased film thickness but reduced coefficient of friction

contact load ratio

contact area ratio and max. von mises stress. And the lubrication performance of nitrile rubber fillering materials bearing is best.
