一、通过铰链四杆运动链分析各二铰接杆间相对运动状况与各杆相对尺寸关系和相对位置关紧之间的联系我们可以对具有不同的各杆相对尺寸关系和相对位置关系的铰链四扦运动链分折其二铰接杆间的相对运动状况。从而总结出规律性的结论;再依据所假定的机架,确定出各种基本类型机构的详细解。我们把各杆间相对尺寸关系分为三种情况:
First, through the hinge four-bar kinematic chain analysis of the relative motion between the two hinge rod relative to the relative size of the bar and the relationship between the relative position of the relationship between the tight We can have different relative relationship between the rod size and relative position of the hinge Sports chain points off the hinge between the relative movement between the two conditions. So as to summarize the conclusion of regularity. Based on the assumed rack, a detailed solution of various basic types of institutions is determined. We put the relative size of the relationship between the rod is divided into three cases:
