Fatiguestrength is less than static stress strength such as elasticity limit, yield strength.
疲劳强度低于弹性极限或屈服强度等静应力强度。

Using present bending fatiguelimit data of gear tooth and other materials of gears, the calculating method of re liability is proposed for bending strength of gear tooth st steady condition.
利用现有齿根弯曲疲劳极限应力数据及其它齿轮资料，提出了稳定工况下齿轮齿根弯曲强度可靠度计算方法。
