| 摘 要： | 考虑齿轮啮合过程中齿间栽荷分布的因素，通过对齿轮原始栽荷历程进行插值修正和雨流计数，运用三维有限元分析方法，探究了齿间栽荷分布对齿轮弯曲疲劳寿命预测的影响。研究结果表明，考虑齿间栽荷分布对齿轮栽荷谱的统计特征有较大影响，并降低了齿轮的弯曲疲劳寿命预测结果。

| Abstract: | By considering factors of load distribution among gear teeth during the course of gear engagement, through carrying out interpolating correction on the journey of primitive loading of gear and rain flow count and utilizing the method of 3D finite element analysis, the influence of prediction on bending fatigue llfe of gear affected by load distribution among gear teeth has been probed. The result of study shows that there are rather big effects on the statistics of load spectrum of gear by considering the load distribution among gear teeth, and lowered the result of prediction on bending fatigue life of gear. |
