| 摘 要： | 本文根据微分几何的包络原理,导出了摆动滚子从动件圆柱凸轮的轮廓曲面方程;在此基础上,讨论了凸轮轮廓的根切条件、滚子与凸轮的接触区域、接触线方向以及凸轮任一圆柱面上实际轮廓曲线的确定;得到了滚子与凸轮任一接触点处的压力角计算公式,并给出了按许用压力角设计的滚子最小接触高度,从而较完整地解决了摆动滚子从动件圆柱凸轮的几何设计问题。

| Abstract: | In this paper, a contour surface equation has been developed for the cylindrical cam with oscillatig roller follower by utillizing enveloping theorm of differential geometry. Based on it, some essential problems, such as the condition of cylindrical cam's undercutting, the contact zone and actual contact curves between the roller and cam, etc. , have been discussed in detail, and the formula of pressure angle as well as the minimum contact height of rollers has been derived too. All of these make the analytical design method for the cam more perfect. |
