孙桓主编的《机械原理》(第三版),在凸轮——连杆组合机构中,有一实现预期运动规律的机构图12-44a,它曾被编入机械工业出版社1979年8月版的《机械工程手册》和西北工业大学《机械设计》(1978年10月版)的凸轮——连杆组合机构部分。在三家有影响的编著书本上,图形的几何形状,各运动副的相对位置都是按比例存在的,而且图号也都用同样字母a表示的。这就给我们排斥了示意图的想法。故此,将该机构运动简图12-44a复制如图1。
Sun Huan editor of the “Principles of Machinery” (third edition), in the cam - connecting rod mechanism, there is a mechanism to achieve the expected movement of Figure 12-44a, which has been incorporated into Mechanical Industry Press, August 1979 edition Mechanical Engineering Handbook “and Northwestern Polytechnical University” Mechanical Design "(October 1978 version) of the cam - connecting rod mechanism section. In the three influential compilation of books, the geometric shape of the figure, the relative position of each pair of movement are in proportion, and the figure numbers are also indicated by the same letter a. This gives us the idea of excluding the schematic. Therefore, the body movement diagram 12-44a copy shown in Figure 1.
