摘要:

本文引入国际标准ISO 230-7:2015中运动误差（Error Motion）的概念来评价气浮动压陀螺马达的回转精度. 基于三点法误差分离技术建立了动压马达回转精度测试系统,得到了动压马达的圆度误差、安装偏心误差和轴心运动误差；提出了基于三点法测量马达转子径向离心和热变形的方法；通过仿真和实验验证了分离结果的准确性. 为在生产中如何定量评价陀螺马达的回转性能进行了有益的探索.

Abstract:

In this paper, the Error Motion in ISO 230-7:2015 is introduced to evaluate the radial rotation accuracy for the gas dynamic gyro motor. A measurement system of rotation accuracy is built up based on 3-points error separation method. The roundness error, eccentricity error of installation and motion error are separated, respectively. In addition, a method to measure the radial centrifugal deformation and thermal deformation is proposed. Finally, the experiment system is set up and the validity of separation accuracy is verified, which provides the basis for the quantitative evaluation of gyro motor rotation accuracy in production process.
