摘　　要：为了解决变比齿轮(变化齿轮多只有几个齿形,亦称变化齿扇)的加工问题,提出一种基于范成法的加工方法。结合变比齿轮副啮合传动规律,推导出了范成法加工变比齿轮的理论公式;在CATIA环境中,建立齿条模型,完成齿轮副的加工装配后,按照推导的加工公式,实现变比齿轮的范成法模拟加工,并进行齿廓修型;采用ADAMS软件,对变比齿轮齿条副进行运动仿真,通过仿真传动比曲线与设计用曲线的对比分析,验证了该方法的可行性。In order to solve the processing problem of the variable ratio gear（ also called variable ratio gear sector）,a machining method based on generation method is put forward. Combining the transmission theory and the meshing movement characteristics of the variable ratio gear and rack,the machining method for the variable ratio gear is presented and the theory formulas related to the processing of the variable ratio gear by generation method are deduced. In CATIA environment,after establishing rack model conforming to the design parameters of the involute rack and finishing the virtual assembly of the gear pair,the simulating processing of the variable ratio gear by generation method is realized,and the profile modification is carried out. Besides,simulation verification of the variable ratio gear and rack is implemented in ADAMS and the feasibility of this method is verified by the contrastive analysis of the transmission ratio curve got by simulation and the designed transmission ratio curve.
