Reliability of Gear-Tooth Bending Fatigu Strength for Through Hardened and Tempered Steel 40Cr

    摘要
  • 摘要: 论述了40Cr钢调质齿轮轮齿弯曲疲劳强度可靠性的试验研究.试验是在4个应力水平（每个应力水平的样本不少于6个）上进行的.在试验数据基础上，拟合出R-S-N曲线及方程.最终获得40Cr钢调质齿轮轮齿在不同可靠度时的弯，弯曲疲劳强度值.

     

    Abstract: The experimental investigation on the reliability of gear-tooth fatigue strength of hardened and tempered steet 40Cr is dealt with. Four loading stress levels (6 samples each) are conducted. Based on the test data, a R-S-N curve and the related equation were fitted. Finally the limiting bending fatigue strength of the 40Cr gear-tooth under different reliabilities are evaluated.
