| 摘 要： | 利用大小两级载荷,对国产某汽车变速箱倒档圆柱齿轮单齿弯曲疲劳强度进行了试验.通过对试验数据的处理,表明该齿轮单齿弯曲对数疲劳寿命在高低载荷级下均呈正态分布,在高低载荷级下的成活率分别与其弯曲疲劳寿命对数之间存在线性函数关系,以及不同成活率下的p S N曲线和齿轮单齿弯曲疲劳极限.为进一步研究齿轮弯曲疲劳强度提供了基本曲线和数据.

| Abstract: | Using two different kinds of loads,the bending fatigue experiments for automobile transmission gear were conducted.Based on test data processing,in medium period of life the linear relationship between the survival rate and the logarithmic life for bending fatigue of gear teeth was obtained.The pSN curves and bending fatigue limit of gear teeth were also acquired under various survival rates. |
