摘　　要：用心形曲柄机构代替导杆机构的曲柄,借助于标准心形线的尖点得到间歇运动机构。该机构具有强急回运动特性。分析了心形曲柄导杆机构的运动特性,讨论了中心距对机构运动特性的影响,给出了心形曲柄导杆机构综合的基本方法以及导杆的最小长度计算方法。Taking the cardioid crank mechanism as the driving mechanism and replacing the crank of the guide-bar mechanism,the dwell mechanism is obtained by means of the sharp point of the standard cardioid.This mechanism has the characteristics of stronger quick return.In this paper,the motion characteristics of the cardioid crank guide-bar mechanism are analyzed,the influence of center distance on the motion characteristics of the mechanism is discussed,and the basic synthesis method of the cardioid crank guide-bar mechanism and the minimum length of the guide rod are given.
