摘　　要：导出了具有急回运动的曲柄摇杆机构运动综合的解析设计方程,从而解决了图解设计带来的质量差的问题。通过对机构进行运动和动力的优化设计,获得了一些重要结论,这些结论对指导这类机构的设计有指导意义。各杆相对于摇杆的杆长比列表可供设计时使用。This paper proposes an analytical design method for the quick-return mechanisms such as the four-bar linkage and developes an optimum design method for those mechanisms in which the time-ratio and the minimum transmission angle are given simultaneously. Using this method, the maximum value of the time-ratio is given only. The quick-return mechanisms in which the minimum transmission angle should be the maximum can be designed easily using the proportion of the links presented in the tables in this paper.
