齿数比对齿面接触强度的影响分析

The Influence of Tooth Number Ratio on the Contact Strength of Gearing

针对齿面接触强度计算公式 ,通过数学变换和数值分析 ,绘制齿面接触应力、安全系数随齿数比的变化曲线 ,寻求渐开线外啮合标准直齿圆柱齿轮齿面接触应力及接触强度随齿数比变化的规律。

Some curves are drawn to show the relation between the tooth number ratio and the tooth contact stress. The influence of overlap ratio on the contact stress are also investigated.
