摘　　要：应用支撑函数法于浮动平底推杆-盘形凸轮组合机构,研究解决了满足第Ⅰ类机构综合问题预设前提——预设凸轮轴心O1(xO1,yO1)条件下,凸轮轮廓曲率半径计算公式和轮廓外凸条件,为解决该类机构的第Ⅰ类综合问题做了铺垫性工作。同时,将支撑函数法推广为适用于浮动平底推杆-盘形凸轮组合机构的一种通用方法。以浮动斜交平底推杆-盘形凸轮组合机构为切入点,得到浮动正交平底-盘形凸轮组合机构的相关研究结果。The supporting function method is applied to floating flat faced pushrod-disc cam combined mechanisms. This paper studies and solves the computational formula of curvature and convexity conditions of the cam profile,which meet the premise of the class Ⅰ synthesis problem,i.e.,preset conditions of the cam axis O1（x O1,y O1）. The results make foreshadowing work for solve the class Ⅰ synthesis problem. Meanwhile,the Supporting function method is extended to a generic method to apply to the floating flat faced pushrod-disc cam combined mechanisms. Takeing floating oblique flat faced pushrod mechanisms as an entry point,the similar results can be obtained on floating orthogonal flat faced pushrod-disc cam combined mechanisms.
