  3. Equations of mesh, shorting contact line, undercutting limit line, meshing limit lines and the existence conditions, angle between the direction of relative speed and the direction of contact line, induced normal curvature about every point on the contact line are established. moreover, the paper also theoretically analyzed the error of the grinded gear surface. on the basis of the theory, the computer program is worked out to automatically produce the contact line and the boundary curves of mesh. analysis of meshing circs under different parameters can be done so that we can gain the best process condition

    首先對漸開面二次包絡理論進行了深入的探討，推導出了兩次嚙合的嚙合方程式、瞬時接觸線方程式、根切界限線方程式、嚙合界限線的方程式及其存在條件，相對運動速度方向與接觸線方向的夾角及接觸線上各點的誘導法曲率；此外，還對磨齒后工件的齒面誤差進行了理論分析；並在理論基礎上編制了相應的計算機程序，自動生成接觸線族及嚙合界限線，對不同參數條件下的嚙合情況進行分析，可以使工藝條件達到最佳狀態；最後研究了磨齒裝置，設計了磨齒機的傳動系統。
