摘　　要：研究数控机床伺服进给系统编码器和连轴器安装不对中与机床控制精度的关联。分析不对中机制,建立不对中振动模型,探讨其对电机输出转矩以及机床伺服进给误差的影响。The relation between fixing misalignment of NC machine tool driving system motor encoder coupling and machine tool control precision was researched. The misalignment mechanism was analyzed,and the misalignment vibration model was built. The misalignment effects on motor output torque and the machine tool servo driving error were discussed.
