摘　　要：传统的弧面凸轮廓面算法是对滚子廓面进行坐标变换,再利用啮合原理导出接触角的计算公式,联立两方程。其最大的缺点是当滚子廓面不为直线时,其廓面方程无法用显式表达,需要解非线性方程,计算量庞大且不便于对同类问题的集中处理。该算法利用微分几何的曲面理论,能直接计算具有任意滚子廓面形状的弧面凸轮的工作轮廓,方法简单易行,便于推广。The traditional algorithm of arc - cam contour surface is the profile surface of roller coordinate trans- formation, then export the contact angle of the formula with the help of engagement theory, simultaneous two equations at last. Its biggest drawback is when the profile surface of the roller is not a straight line, the profile equation can not explicit expression, which for solving nonlinear equations and the computation is huge and not easy to focus on similar problems. With the differential geometry of surfaces theory, the are cam profile can be calculated directly with any roller profile shape. The method is simple and easy to spread.
