摘要
本文探讨了双圆弧齿轮接触疲劳极限的计算方法。在试验的基础上，得到碳钢调质ＧＢ１２７５９－９１型双圆弧齿轮的接触疲劳极限σＨＬｉｍ。
In this paper, the method for the calculation of surface fatigue strength of W N gears is discussed. Based on the experiments, the σ HLim of hardness and tempered steel of the gears has been obtained. The minimum safety factor for strength calculation of the gears is recommended.
