推导了四种蹄端带滚轮的S形制动凸轮特性参数随凸轮转角变化的计算公式,进行了实例计算,并给出了特性曲线,还对计算结果进行了分析,讨论了用圆弧线代替阿基米德螺线的作图法。
The calculation formulas of the characteristic parameters of the S-shaped brake cam with four kinds of hoof rollers are deduced with the change of the cam angle. The calculation examples are given and the characteristic curves are given. The calculation results are also analyzed. Instead of Archimedean spiral mapping.
