摘　　要：关于作平面运动滚子从动件盘形凸轮机构的第Ⅰ类机构综合问题,迄今未获得圆满解决。基于类速度图原理,通过提出瞬时区域套/边界Γ(x,y)和?Γ(x,y)的新概念、生成原理和解析表达、整程∠P20Hx-θ1线图及各种可能情形,整程区域套/边界Γ*(x,y)和?Γ*(x,y)的概念、生成原理和锁定区间套,特别是提出Γ*(x,y)和?Γ*(x,y)的解析和离散数值求解方法、整程区域套Γ*(x,y)的收缩规律特征和脊线{O**}的客观存在性等,较为圆满地解决了作平面运动滚子从动件盘形凸轮机构的第Ⅰ类机构综合问题。Up to now, the class-I synthesis problem of the disc-cam mechanism with a planar motion roller-follower is not solved yet.The concepts of instantaneous area set/boundary, the diagram of the whole set and the whole area set/boundary were proposed. The solution and generation principles based on the principle of velocity diagram were also presented. Moreover, the shrinkage characteristic of the whole area set and the objective existence of the ridge line were described. Finally, the class-I synthesis of the mechanism was solved and an example of the mechanism synthesis was given.
