摘　　要：通过植入“往程、返程”和“F型机构／P型机构”等关键性概念，并将共轭凸轮机构划分为主凸轮机构、副凸轮机构，进行分割独立性研究，提出副凸轮机构（即P型机构）的“瞬时一维直线区域”生成的基本原理图和vC1-θ1、VC2-θ1和UK-θ1曲线，特别是揭示出其与主凸轮机构（即F型机构）的差异性内涵，解决了浮动平底推杆P型机构和共轭凸轮机构的第Ⅱ类机构综合问题。By adopting the concepts of ＂rise and return travel＂ and ＂ F/P type mechanism＂ and dividing the conjugate cam mechanism into main cam and assistant cam mechanism, which were studied respectively, the basic schematic diagram of instantaneous one dimensional linear area of the assistant cam （i. e. P type mechanism） and the curves of vc1 -θ1,Vc2 -θ1 and uK -θ1 were proposed. And the differences between the main cam （ i. e. F type mechanism） and the assistant cam （ i. e. P type mechanism） were presented. The class Ⅱ synthesis of P type mechanism and conjugate cam mechanism with floating flat face pushrod was resolved.
