齿轮材料、失效形式和计算准则：
Materials of gears 齿轮材料
Types of failures 失效形式
Design criteria 计算准则
Types of failure 失效形式：
Tooth breakage轮齿折断
Failure of tooth surface layers 齿面损伤：
Fatigue pitting, seizing, abrasive
wear and plastic flow of material
点蚀、胶合、磨损和塑性变形
Close gearing闭式齿轮传动： The principal types of failure are pitting, tooth breakage and seizing of the teeth. And seizing of the teeth occurs under heavy load and calculation in checking for the possibility of tooth seizure is not effective. Hence, only calculations of the contacting fatigue strength and bending fatigue strength are carried out.以点蚀、轮齿折断和胶合失效形式为主，其中胶合发生于重载，而且计算方法不成熟，所以一般只进行齿面接触疲劳强度和齿根弯曲疲劳强度计算。
