摘　　要：指出了用最小传动角衡量机构力传递性能的不足,提出了机构工作行程平均传动角的概念。计算结果显示,相对最小传动角,平均传动角更好地反映了机构力传递性能。分析了计算曲柄摇杆机构平均传动角的主要问题,给出了曲柄摇杆机构平均传动角的计算框图,简要分析了工作行程平均传动角在平面连杆机构设计中的应用。this paper, It is proved that using minimums transmission angle to measure the characteristic of force transmission is imperfect, the concept of average transmission angle is offered. Our calculation results on the transmission angle show that calculating average transmission angle is better to measure the characteristic of force transmission of mechanism, than calculating minimums transmission angle. The method for calculating average transmission angle of crank-rocker mechanism is discussed and the flowchart for calculating average transmission angle is showed, the application of average transmission angle in design ofplanear linkage is briefly analyzed.
