摘要
针对18Cr2Ni4WA渗碳淬火齿轮弯曲疲劳试验,介绍试验方法、试验齿轮、试验机及夹具,说明应力水平确定方法,最后通过失效判据判定失效寿命得出试验点数据,根据试验数据拟合出R—S—N曲线,并对试验数据处理方法进行探索。根据试验数据确定其寿命的威布尔分布,为渗碳淬火齿轮的可靠性定量评估提供一种切实可行的方法,为齿轮可靠性设计提供基础试验数据。
Deal with the bench 18Cr2Ni4WA carburizing and quenching gear bending fatigue experiment,the experimental method,experimental gear,experimental machine and fixture,stress levels are introduced,the experimental sites data obtained from gear failure life,the R—S—N curve is fitted according to experiment data,the experimental sites data processing method is also explored.The Weibull distributing made scientific researches on test gear was put forward and the concrete distributing of bending fatigue life is confirmed.Meanwhile,a faithfully way with reliability analysis of the carburizing and quenching gear is provided.Otherwise,based test data for gear reliability design.
