摘　　要：研究了摆动滚子从动件凸轮机构的加工与从动件位移误差之间的关系,推导出了从动件位移误差计算公式,该公式可用于分析计算从动件位移误差。指出了合理选定凸轮机构的参数和加工精度,可减小从动件位移误差,提高摆动滚子从动件凸轮机构的运动精度。The relationship between the installment and machining errors and the follower displacement error for a swing roller follower plate cam was studied. The formulae of the follower angular displacement error were derived. These expressions can be used to calculate the follower angular displacement error. The follower displacement error of a swing roller follower cam system is closely related to the cam geometric error and offset distance error. By taking the values and signs of the cam geometric error and offset distance error properly, we can minimize the swing roller follower angular displacement error and design the high precision swing roller follower plate cam.
