tooth root bending-fatigue strength 齿根弯曲疲劳强度
The speed reducer gear tooth surface through contact fatigue strength to calculate, through the tooth root bending fatigue strength check;
减速器中齿轮通过齿面接触疲劳强度来计算，通过齿根弯曲疲劳强度验算；
Especially the accurate modeling of the transition curve of dedendum, which ensures the accuracy of bending fatigue strength of the tooth root by the finite element analysis.
特别是对齿根过渡曲线白勺准确建模，保证了对齿根弯曲疲劳强度停止有限元分析白勺准确性。
