摘　　要：针对汽车变速比转向器的非圆齿扇设计复杂且在加工过程存在一定难度的问题,基于包络原理,利用齿条范成法,推导出非圆齿扇插齿加工的三轴联动数学模型,并以华中8型通用数控系统为开发平台,利用接口函数编程,二次开发出了相应的数控插齿系统。最后以余弦式传动比非圆齿扇为例,在该数控插齿系统上进行了加工仿真,仿真结果证明了开发这种数控插齿系统的可行性与正确性。Aiming at the problem of the difficulty and complexity in the machining process of the non-circular gear sector,using rack generating principle,a 3-axis linkage mathematical model of shaping non-circular gear based on the model of the envelope was first obtained in the paper.Taking the HNC8 as the development platform as well as the interface function,the corresponding NC system was then redeveloped.Finally,the simulation of the NC cutting machine was carried out by using cosine tape transmission.The simulation result proves the feasibility and validity of the development of this kind of NC system.
