摘　　要：基于平面四杆机构的空间模型,针对具有急回特性的I、Ⅱ型曲柄摇杆机构,深入分析了机构最小传动角、极位夹角和摇杆摆角等运动性能参数与构件尺寸之间的内在关系;指出了构件尺寸的变化对这些运动性能指标的影响;得出了相应的结论,并通过实例说明了这些结论的应用。For type Ⅰ and type Ⅱ crank-rocker mechanisms with quick return characteristics, there exist some inherent relations between the link dimensions and the kinematics capability parameters, such as minimum transmission angle, extreme position angle and angular stroke of rocker. Based on the three-dimensional models of the type Ⅰ and type Ⅱ crank-rocker mechanisms, the relations has been analyzed in this paper, and some conclusions obtained.Examples has been given to show the correct applications of these conclusions.
