本文探讨了复动全开口提花机摆动从动件近似等径凸轮刀箱传动机构的设计原理。给出了这种机构的近似等径条件，等速封闭机构设计与运动分析结果，按许用压力角设计最小凸轮机构参数的求解公式以及凸轮廓线设计公式；并实例计算出该机构的参数、回程规律及凸轮廓线设计结果。本文为同类机构的设计提供可实际应用的解析方法。 This article explores the design principle of the reciprocating full-opening jacquard swing follower approximately equal-radius cam box transmission mechanism. The approximate isosceles conditions of such mechanism are given. The results of the design and motion analysis of the isokinetic closed mechanism, the formula of the minimum cam mechanism parameters and the design formula of the cam profile are designed according to the allowable pressure angle, and the parameters of this mechanism are calculated , Return Law and Cam Profile Design Results. This article provides practical analytical methods for the design of similar institutions.
