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。 -
Tooth surface equations and contact line equations of the involute worm gearing are established according to its machining methodology. meshing characteristics in rigidity condition are studied. these characters include the inductive normal curvature along the contact line on the worm surface, the first and the second limit lines during the engage of the worm gear, and the influence of the intersect angle between the contact line the relative velocity of the worm and the gear on transmission performance
根據漸開線圓柱蝸桿傳動的創成方法，建立了漸開線圓柱蝸桿和蝸輪的接觸線方程式、齒面方程式，分析了漸開線圓柱蝸桿傳動的剛性嚙合特性，如蝸桿與蝸輪嚙合時的誘導法曲率、一類界限曲線、二類界限曲線和蝸桿與蝸輪間相對速度方向和接觸線方向的夾角對傳動性能的影響； 2 -
Then a fast computing method is presented to estimate the curvature of edge points and the points at which curvature is less than some threshold are collected to fit lines
為提取直線邊緣，使用改進的序列細化演算法將邊緣細化為單像素寬，而後用一種快速曲率估計方法估算邊緣點的曲率，並保留估算值很小（約等於零）的點擬合直線。
