剃齿啮合线与渐开线齿轮齿面直母线垂直关系的解析证明

An Analytic Verification on the Vertical Relations Between Gearing Line and Straight Generating Lines of Involute Helicoid in Gear Shaving

对普通剃齿时啮合线与齿面直母线的空间垂直关系进行了数学解析证明，以帮助人们对这一关系加深理解，为进一步深入研究剃齿啮合理论打下基础。

The space perpendicular relationship between the gearing line and the straight generating lines of gear tooth in gear shaving is proved with the analytic mathematics,which can help people understand the relation deeply and can lay down a foundation for making further study of the meshing theory in gear shaving.
