摘要
论述35CrMo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1603型电磁谐振疲劳试验机上进行的的，分4个应力级，每个应力缓的试验样本不少于7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35CrMo调质齿轮轮齿的弯曲疲劳强度极限，
Deals with the experimental investigation on the reliability of gear-tooth fatigue for through hardening steel 35CrMo. The tests were canied out on a electro-mag-netic resonance fatigue test machine of type 1603 (U. K). Four loading stress levels (7 sample for each test )were conducted. Based on the test data, a R - S- N curve and related equation were fitted. Finally, the limiting bending fatigue strengh of the 35CrMo gear-tooth under different reliability have been evaluated.
