摘　　要：论述３７ＳｉＭｎ２ＭｏＶ调质齿轮轮齿弯曲疲劳强度的可靠性试验研究，该试验是在英国制造的ＥＭＲ－１６０３型电磁谐振疲劳试验机上进行的，分４个应力级，每个应力级的试验样本不少于６个。在试验数据基础上，拟合出Ｒ－Ｓ－Ｎ曲线及方程，最后求得不同可靠度下３７ＳｉＭｎ２ＭｏＶ调质齿轮轮齿的弯曲疲劳强度极限。The experimental investigation on the reliability of gear-tooth fatigue strength for through hardening steel 37SiMn2MoV was tested. The tests were carried out on a electro- magnetic resonance fatique test machine of type EMR-1603 (U. K). Four loading sbtrss levels (of 6 samples each) were conducted. Based on the test data, the R-S-N curves and the related equations were fitted. Finally, the limiting bending fatique strength of the 37SiMn2MoV gear-tooth under different reliabilities have been evaluated.
