Research on Eccentric Placement Segmented Ring Gear Milling Method Based on VERICUT

为解决大直径且齿宽较宽的分段式齿圈的铣齿问题,提出采用偏心放置的主程序调用子程序循环加工的铣齿方法。根据主程序数学模型和子程序数学模型构建偏心放置铣齿方法的数学模型,基于VERICUT的仿真模型和仿真主、子程序,实现齿槽的开粗和精铣仿真加工;通过VERICUT对比分析功能模块,以齿面残留模型为依据,验证了偏心放置铣齿方法的可行性。

To solve the problem of gear milling for segmented ring gear with large diameter and wide tooth width,a milling method of eccentric main program calling subroutine is proposed.According to the mathematical model of the main program and the mathematical model of the subprogram,the mathematical model of the eccentric placement gear milling method is constructed.Based on the simulation model of VERICUT and the simulation main and subroutines,the simulation machining of cogging and fine milling is realized.Through the comparative analysis function module of VERICUT,the feasibility of the eccentric placement gear milling method is verified based on the residual tooth surface model.
