摘　　要：在给定凸轮机构的运动规律和许用压力角的条件下,提出了一种基于Matlab按许用压力角设计直动滚子推杆盘形凸轮机构的通用方法,克服了传统设计凸轮轮廓计算方法复杂,效率低且求解精度不高的缺点,能够保证凸轮机构在任何瞬时压力角都不超过许用压力角,有效地平衡了凸轮机构的尺寸紧凑和传力特性,系统解决了按许用压力角设计凸轮机构尺寸的综合问题,并结合Pro/E进行了凸轮三维实体的精确设计。仿真验证结果表明,凸轮机构的压力角满足设计要求。Under the conditions of given kinematic law and allowable pressure angle,this paper presents a general method to design disk CAM with translating follower based on Matlab.Compared with conventional method,it can overcome the disadvantages of complex calculation,low efficiency and precision.It can also guarantee that the pressure angle of CAM mechanism is smaller than the allowable pressure angle at any time,and the compact and force transmission characteristics of the CAM mechanism are effectively balanced,so the synthesis of the sizes for disk CAM mechanism in accordance with allowable pressure angle is solved systematically.The accurate design for the CAM Contour curve is obtained by using Pro/E.Through the simulation,the pressure angle of the cam mechanism can meet the design requirements.
