摘　　要：为了提高滚动轴承旋转精度测试系统的测试精度,研究多种高精度主轴旋转误差测量方法.结合测试系统原理与结构,采用两点法误差分离方法实现测试系统空气静压主轴旋转误差的高精度测量.通过对比多组测试系统所分离的精密芯轴圆度结果与圆度仪测量结果,间接分析两点法误差分离方法的精度与稳定性.测试结果显示:应用两点法误差分离方法所得的测试系统主轴旋转误差结果精度高、稳定性好;验证了在载荷作用下该测试系统所采用的空气静压主轴旋转误差较小,且随着转速的增加仅小幅增加.Several measurement methods error motion of the principle and structure of measurement system, the high precision spindle were investigated. Based on double-probe error separation method was applied to precisely measure the error motion of aerostatic spindle. The precision and stability of the double-probe error separation method were analyzed indirectly by comparing the mandrel roundness results between error separation method and roundness tester. Results showed that the error motion of the aerostatic spindle is measured by the double-probe method precisely and stability. Additional, the measurement results demonstrate that error motion of the aerostatic spindle is much small, and the value slightly increases as the speed increases.
