摘要
本文对２５Ｃｒ２ＭｏＶ离子渗氮齿轮所进行的齿面接触疲劳和轮齿弯曲疲劳试验研究，得出了这种齿轮疲劳寿命分布规律和疲劳强度分布规律的结论，并求得这种齿轮的Ｒ－Ｓ－Ｎ线簇方程以及各种可靠度下的齿轮接触疲劳极限应力值和轮齿弯曲疲劳极限应力值．
Both tooth flank contact fatigue and tooth bending fatigue with ion-nitrogen case-hardening 25Cr2MoV steel gears were investigated. The conclusions of distributing rules both their fatigue lives and fatigue strength were obtained were investigated.The R-S-N curve equations,both limiting stress of tooth flank contact fatigue and limiting stress value of tooth bending fatigue under various reliabilities were also evaluated.
