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Ｃｎｄ──Ｓ──Ｎ曲线并获得各种可靠度下的弯曲疲劳极限值．
Reports the experimental investigation on the reliability of gear-tooth bending fatigue strengthfor 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 werethen Processed with statistic method. Complete C-R-S-N curves were thus fitted and as a result, the values oflimits of bending fatigue under various reliabilitys were gained.
