【摘要】 为研究一批行星齿轮件可能的疲劳寿命,采用正交试验法,以齿根圆角半径、材料的弯曲疲劳极限、齿根粗糙度3个因素作为自变量设计了正交试验;运用Romax软件建立了某轮式装载机轮边减速器仿真模型,根据真实的传动系载荷谱,基于疲劳累积损伤原则,预测了行星齿轮在不同因素水平组合下的弯曲疲劳寿命,并分析了三者的影响程度。结果表明,该批行星齿轮件的疲劳寿命的波动区间为4.13×106到2.71×107次循环,且以齿根圆角半径产生的影响为最大。更多还原

【Abstract】 For study the possibly fatigue life of a group planetary gear,this paper used orthogonal experiment,select the tooth root fillet radius,material bending fatigue limit,the tooth root surface roughness of three factors as variables to design the orthogonal experiment;Established the round edge reducer simulation model using Romax software,accorded the actual load spectrum,planetary gear on different level,and analysised the relationship between the degree of influence x 107 cycles,and the macimum influence come from the tooth root fillet radius.更多还原
