We need to consider the deformation of only one strip parallel to generatrix of the cylinder.我们只需要考虑一个平行于圆柱母线的窄条的变形。
Formula to evaluate translation of the tooth-surface and the equation to describe the generatrix of the negatively cambered sooth-surface were derived, respectively.分别推导得到齿面平移距离和内凹齿面母线方程的计算公式。
