| 摘 要： | 导圆锥滚子轴承是直升机传动系统中的重要组成元件,直母线圆锥滚子轴承存在"边缘效应"。研究表明,轴承的寿命与应力的7次方成反比。为了降低轴承工作过程中的应力水平,提高轴承寿命,需要准确设计不同工况条件下圆锥滚子的凸度值。本文通过有限元分析与Romax对比计算,得到Romax设计滚子凸度可以在保证计算精度的情况下,显著提高计算效率的结论。

| Abstract: | Tapered roller bearing is an important element of helicopter transmission system. The straight generatrix tapered roller bearings have＆quot;edge effect＆quot;. A large number of research shows that the bearing life is in inverse proportion to the 7 power of stress. In order to reduce the load stress, and prolong the service life of bearings, accurate design on tapered roller crown under different working conditions will be needed. Compared with Finite element calculation, Romax designer can save the calculation time in roller crown design under the same accuracy.. |
