摘　　要：在动力伺服刀架中,转位系统的精度是刀架可靠性的重要指标之一。研究的齿轮即为刀架转位系统中的传动齿轮。齿轮的几何学特性直接影响齿轮的传动精度,进而影响刀架转位系统的一次定位精度,因而对齿轮系统进行传动精度分析很有必要。以某动力伺服刀架中齿轮为例分析了其几何偏心对传动精度的影响;阐述了基于NX、ADAMS的误差齿轮分析系统的建模过程;将仿真分析数据与理论计算结果进行对比,验证了基于动力学分析方式分析齿轮运动学特性的可行性,同时验证了传统解析法的正确性;最后编写CMD文件,实现ADAMS多次实验的自动化操作。In dynamic servo tool holder, the precision of the inversion system is one of the important indicators of the reliability of the resL Research of the transmission gear is the gear in the tool post transfer system Gear geometry characteristics directly affects the transmission accuracy of gear, and then affects the tool rest one-time positioning precision of the inversion system, thus driving gear system accuracy analysis is necessary. A gear in a power servo turret is explored to analyze the effects on the transmission accuracy brought by its geometric eccentricity. The modeling process based on NX and the gear error analysis system in ADAMS/s presented. The feasibility of the method analyzing the gear＇s kinematic characteristics based on the analysis of dynamics, as well as the correctness of the traditional analytic method is verified by contrasting the theoretical result with the data processed A CMDfile is created which realize the automation of ADAMS simulation.
