摘　　要：螺旋锥齿轮铣齿机在数控加工过程中经常出现冲击和振荡等现象,严重影响齿轮加工精度。研究发现伺服传动系统中存在的齿隙非线性问题对铣齿机的加工精度、可靠性和稳定性有较大影响。通过比较消除齿隙方法,提出一种基于PMAC运动控制器的铣齿机传动系统双电机消隙方法。对双电机消隙的基本原理以及消除间隙的过程进行分析,并且根据双电机消隙原理设计试验流程;搭建基于“IPC+PMAC运动控制器”的双电机驱动应用系统,并在PMAC IDE中进行相关配置;最后基于上、下位机结构配置的数控系统试验装置,进行试验验证。试验结果表明:所提方法能够有效抑制齿隙非线性的干扰、提高系统的稳定性,证明所提双电机伺服消隙方案的可靠性。In the CNC machining process,the spiral bevel gear milling machine often has phenomena such as shock and oscillation,which seriously affect the machining accuracy of the gear.It is found that the nonlinear problem of backlash in the servo transmission system has a great influence on the machining accuracy,reliability and stability of the gear milling machine.By comparing the methods of eliminating backlash,a dual-motor backlash elimination method was proposed for gear milling machine transmission system based on PMAC motion controller.The basic principle of dual-motor backlash elimination and the process of eliminating backlash were analyzed,and the test process was designed according to the dual-motor backlash elimination principle;a dual-motor drive application system was built based on“IPC+PMAC motion controller”,and the relevant configuration was performed in PMAC IDE;finally,the experimental verification was carried out through the numerical control system test device based on the structure configuration of the upper and lower computers.The proposed method can effectively suppress the nonlinear interference and improve the stability of the system,the reliability of the proposed dual-motor servo anti-backlash scheme is proved.
