In order to raise efficacy of the Geneva driving by eliminating flexible shock and reducing inertia load, a new design method of Geneva mechanisms is presented based on kinematics, geometry shape and meshing simulation of the mechanisms. The design of configuration and driving for Geneva mechanisms has been discussed by using meshing generation analysis of the drive pin and slot in which the geometric shape design of the non-circular section driving pin and meshing slot are taken as the course, and the improve the dynamic character of the Geneva are taken as the object. It is proven that dynamic character and working capacity can be remarkably improved by designing of the practical exam- ples for Geneva mechanism. The quantity and efficiency of Geneva mechanism design are greatly raised by using of simulation analysis. This design method can be used to the transmission design and machining simulation analysis for the high speed Geneva mechanism without any shock.为了消除槽轮传动的柔性冲击和减小惯性负载以提高槽轮机构传动功效,提出了一种基于机构运动学和几何形状及啮合仿真的槽轮机构设计方法.研究以非圆截面驱动拨销和轮槽的几何形状设计为途径,以改善槽轮动力学特性为目标,利用拨销与轮槽创成运动分析进行槽轮机构的结构与传动设计.通过实例设计证明了该方法可实现槽轮动力特性和承载能力的显著改善.利用仿真分析进行槽轮机构的设计大大提高了设计质量和效率.该方法可用于高速精密无冲击槽轮机构的传动设计及加工仿真分析.
