摘　　要：以行星轮和滚动轴承配合模型为研究对象,运用有限元法进行了应力分析,应用疲劳寿命分析软件FE-SAFE进行了疲劳寿命分析,并分析了过盈量对疲劳寿命的影响,得出了当过盈量小于0.08 mm时,减小过盈量可以提高齿根处疲劳寿命。Focusing on the planetary gear and rolling bearing model, the article analyzes the gear ’s root bending stress by using the finite element method and fatigue life with the help of FE-SAFE software. The article also considers the influence of the model ’s interference on fatigue life, which concludes that to decrease the model’s interference can improve the planetary gear’s fatigue life significantly when the amount of interference is less than 0.08 millimeter.
