Retiability of Gear-tooth Bending Fatigue Strength for 25Cr2MoV Ionitriding Gear

摘要: 25Cr2MoV离子渗氮齿轮弯曲疲劳强度的可靠度试验是在STRON1603型电磁谐振疲劳试验机上进行的.短寿命区采用4级恒定应力水平的成组试验法;长寿命区采用应力升降试验法.对试验结果数据进行了统计学处理,拟会出完整的C——R——S——N曲线并获得各种可靠度下的弯曲疲劳极限值.

Abstract: Reports the experimental investigation on the reliability of gear-tooth bending fatigue strength for 25Cr2MoV ionitriding gear. The tests were carried out on a Electro-magnetic resonance fatigue test ma-chine of type STRON 1 603. The grouping test method at four constant stress levels was applied for short life-span areas while the stress up-and-down test method were used for long life-span areas. The tested data were then Processed with statistic method. Complete C-R-S-N curves were thus fitted and as a result, the values of limits of bending fatigue under various reliabilitys were gained.
