摘　　要：建立了绕椭圆柱面以等角速度旋转,又以变速度上升的非定常螺距的螺旋线方程。给出了螺距作为加速度函数的数学表达式、螺旋线上任意点的曲率、挠率及弧长的计算公式,讨论了其相关特性。通过实例,研究了非定常螺距的螺旋线方程在自动流水线中的应用。A helix equation of time-varying pitch is established, revolving elliptic cylinder as equal angular velocity and rising as variable velocity at the same time. The mechanical expression of the acceleration function of time-varying pitch, the curvature and torsion of helix, and calculate formula of arc length of helix is given, and correlative characteristics and discussed. The application of a helix equation of time-varying pitch in mechanical drive and automatic assembly line is studied through an example.
