摘　　要：为得到某合金钢感应淬火齿轮的接触疲劳特性,采用疲劳极限应力快速测定法和常规成组法相结合的方案对其进行疲劳试验。通过两参数威布尔分布和对数正态分布分别对试验数据进行处理,拟合出可靠度—应力—寿命曲线(即R—S—N曲线),得到不同可靠度下的疲劳极限应力值,为感应淬火齿轮接触疲劳有限寿命设计及可靠性设计提供了基础试验数据。The rapid test method for the fatigue limit stress combined with conventional group method is used to get the contact fatigue strength of induction hardening gear made of steel alloys.The reliability-stress-life curve（R-S-N curve）is fitted according to experimental data with the twoparameter Weibull distribution and lognormal distribution.Thus the values of stress fatigue limit under different reliabilities can be respectively got,which provides basic data for the contact fatigue life and reliability design of the induction hardening gear.
