摘要
圆锥滚子轴承的承载能力较大,广泛应用于重载的冶金、矿山等设备。圆锥滚子轴承中滚子的不同凸型及凸度量设计对滚子及套圈的应力分布以及弹性变形都有十分显著的影响,直接关系到滚动轴承的承载能力和疲劳寿命。文中利用有限元法(FEM),通过对圆锥滚子轴承不同凸型及凸度量的滚子设计时滚子母线与滚道接触区域的应力分布状况进行对比分析,得到了圆锥滚子的凸度设计最优方案,找出了轴承早期损坏的原因,优化结果表明,轴承的实际使用寿命提高了约93%,分析结果对提高该型轴承的寿命具有重要技术意义,也为圆锥滚子轴承设计提供一个新的方法。
Tapered roller bearings which has large carrying capacity are widely used in heavy-duty equipment. The different designs of rollers with varied convexity have noticeable effects on stress distribution and elastic deformation~ The designs are directly related to the load capability and the life length of the roller bearing. Stress distribution of contact area between roller busbar and raceway with different convexity designs of tapered bearing rollers has been analyzed using Finite Element Method （FEM） analysis, the best solution for the design of convexity of tapered rollers is achieved and the cause of early destroy of roller bearings is found. The optimal result shows that the service life of bearing improved by 93%. Hence, a more efficient method of improving the service life of tapered roller bearings is got.
