機械設計基礎之Toothed gearing齒輪傳動內容提要：
齒輪材料、失效形式和計算準則：
Materials of gears 齒輪材料
Types of failures 失效形式
Design criteria 計算準則
Types of failure 失效形式：
Tooth breakage輪齒折斷
Failure of tooth surface layers 齒麵損傷：
Fatigue pitting, seizing, abrasive
wear and plastic flow of material
點蝕、膠合、磨損和塑性變形
Close gearing閉式齒輪傳動： 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.以點蝕、輪齒折斷和膠合失效形式為主，其中膠合發生於重載，而且計算方法不成熟，所以一般隻進行齒麵接觸疲勞強度和齒根彎曲疲勞強度計算。
