双向圆弧齿轮传动的啮合分析（二）──双向圆弧齿轮的曲率分析

通过对产形面曲率和包络切齿时产形面与齿曲面相对运动关系的分析，推导出双向圆弧齿轮齿面的诱导法曲率、诱导短程挠率和齿面的主曲率、主方向等计算公式。这对分析双向圆弧齿轮的齿面结构、接触区域、润滑设计和强度计算都是至关重要的。

Engagement Analysis of a New-Pattern Double-Circular-Arc Gear Transmission(2)

After analyzing the curvature of the forming surface and the relativ emotion between the forming surface and the curved tooth surface during envelope tooth cutting,the authors work out the equations for calculating the induced normal curvature and geodesic deflection,the principal curvature and direction of the tooth surface of this kind of circular-arc gear. This is of great importance to the analysis of the tooth flank profile,contact area,lubrication design and strength calculation of the above-mentioned gear.
