| 摘 要： | 基于啮合原理研究了具有曲线轮廓的槽轮机构的啮合特性,给出了轮槽廓线设计的通用表达式,并提出了该机构设计时需要考虑的问题。与普通槽轮机构相比,这种槽轮机构可以通过选择合适的运动规律类型、滚子半径和其它条件设计出曲线轮槽,从而可以消除从动件在每一个运动循环的起始和中止时由于非零加速度产生的冲击载荷,因而适用于中速和高速场合。该方法使得普通槽轮机构成为其特例。最后并以一实例展示了该方法的应用。

| Abstract: | Design of planar Geneva mechanisms with curved slots is studied in order to eliminate the shock load caused by non-zero acceleration at the start and the end of each motion cycle of the follower in the case of a classical planar Geneva mechanism.Based on theory of engagement,a generic equation group is derived,and the profiles of curved slots can be obtained by solving this equation group if the radius of the roller and the motion law of the follower as well as other conditions are specified.This makes the ... |
