本文分析了轴承的误差特性,根据试验数据,提出了精密跟踪雷达、卫星地面跟踪站及射电望远镜的俯仰轴承一种经济设计方法:予先仔细测量出轴承偏心方向和大小,装配时按标定的方向安装,或选用轴承相对径向跳动最小的90°范围工作,提高雷达的指向精度。
In this paper, the error characteristics of the bearing are analyzed. Based on the experimental data, an economical design method of the pitch bearing of the precision tracking radar, the satellite ground tracking station and the radio telescope is proposed. The eccentric direction and size of the bearing are carefully measured beforehand, Direction of installation, or use the relative radial bearing minimum 90 ° range of work to improve the pointing accuracy of the radar.
