摘　　要：用一个新的基本观点——把齿轮弯曲疲劳失效处理成随机事件，以这个随机事件为研究对象，用齿轮弯曲疲劳的疲劳损伤强度Ｋｗ和总疲劳损伤量Ｄｗ描述弯曲疲劳失效随机事件，得出用概率描述的弯曲疲劳的疲劳累积损伤模型。用这个计算模型，提出了计算齿轮弯曲疲劳可靠度的计算方法。In this paper,a new basic point that the fatigue faliure of gear bent under load is a random eventis used to research the probletn of gear bent fatigue,The random event of the gear bent fatigue faiiure is describedby two random yariables Kwthat is the damage strength of the gear bent fatigue and Dwthat is overall tatigue da-mage quantity,so that a new fatigue cumulative damage model of the gear bent fatigue。which is described by proba-bility,is obtained.According to the model,the computation method of fatigue reliability when gear bent under loadis put forward.
