成对轴承的安装与轴系误差补偿方法

摘要

The measurement method of bearing inner ring radial runout and the installation methods of paired bearings are introduced. By comparing and analyzing the two installation modes of both in the same and opposite di⁃rections of radial runout of the paired bearings, it is concluded that when the bearing is installed in the same direc⁃tion of radial runout, the translation error of axis is increased to reduce the shaking error of the shafting system. So the effect of compensating shafting system error is obtained and the rotation accuracy of the shafting system is im⁃proved. After the errors of Class P5 paired bearings are compensated, the maximum shaking error of the shafting system is 2.45 second of arc.%介绍了轴承内圈径向跳动的测量方法及成对轴承的安装方式。通过对成对轴承径向跳动方向相反和相同的两种安装方式进行比较分析，得出轴承与径向跳动方向一致安装时，可以通过增大轴线的平移误差来减小轴系晃动误差的方法，达到补偿轴系误差的效果，有效地提高了轴系的回转精度。P5级成对轴承经误差补偿后，轴系的最大晃动误差为2.45角秒。
