螺旋齿轮传动齿面接触疲劳强度计算及影响因素

The Calulation and Affect Factors of Contact Fatigue Strength Far Gear Grivc Surface of Spiral Gear

在分析了螺旋齿轮接触点几何特征的基础上，提出了螺旋齿轮齿面接触疲劳强度计算公式．并分析了影响因素及影响规律。这对在工程实践中更有效地应用螺旋齿轮传动有一定意义。

Analysing the geometric charactors of the contact point of spiral gear. the peper brings up the calculate formula of constant fatigue strength for surface of spiral gears, and it also analyses the affect factors and affect law.There is diective function for using spiral gear drive effectively in engineering practice.
