Description
技术领域 technical field
本发明涉及轴承技术领域，尤其是一种高速转子及使用该转子的控制力矩陀螺。 The invention relates to the technical field of bearings, in particular to a high-speed rotor and a control moment gyroscope using the rotor.
背景技术 Background technique
控制力矩陀螺是航天领域的姿态控制系统中应用较为广泛的执行机构，而高速转子是控制力矩陀螺的核心旋转部件。高速转子壳体及设于壳体内的轮体，其中轮体在工作时通过一对角接触球轴承作为旋转支撑转动装配于高速转子的壳体上，并通过通过加载环及固定装配于所述壳体上的轴承压盖对两角接触球轴承施加轴向定位预载，从而保证高速转子的轴系具有适宜刚度，进而保证高速转子的平稳运转。其中所述轮体由于需要在工作时高速旋转，因此其材料要求较为严格，这就使得轮体与高速转子的壳体的材料线膨胀系数产生差异。然而，高速转子的工作环境一般都有温差，这则无法避免的使得轮体及壳体均产生热胀冷缩，而由于材质的差异，轮体和壳体之间的线膨胀值不等，所述的轴承压盖又是固定装配于所述壳体上的，因此工作过程中，从低温、常温到高温，由温度的变化引起的轮体和壳体之间的不同涨缩量将导致轴承的预载发生变化，引起轴承动态摩擦力矩的波动和不稳定，不利于轴承的正常工作，严重时会导致轴承的失效，从而造成控制力矩陀螺高速转子及控制力矩陀螺的失效；因此目前的控制力矩陀螺适用的温度范围较窄，在一些温差较大的环境中则无法适用。 The control moment gyroscope is a widely used actuator in the attitude control system in the aerospace field, and the high-speed rotor is the core rotating part of the control moment gyroscope. The high-speed rotor casing and the wheel body inside the casing, wherein the wheel body is rotatably assembled on the high-speed rotor casing through a pair of angular contact ball bearings as a rotating support during operation, and is fixedly mounted on the high-speed rotor casing through the loading ring and The bearing gland on the casing applies axial positioning preload to the two angular contact ball bearings, thereby ensuring the shafting of the high-speed rotor has appropriate rigidity, thereby ensuring the smooth operation of the high-speed rotor. Wherein the wheel body needs to rotate at high speed during operation, so its material requirements are relatively strict, which causes a difference in the coefficient of linear expansion of the material of the wheel body and the casing of the high-speed rotor. However, the working environment of high-speed rotors generally has a temperature difference, which inevitably causes thermal expansion and contraction of the wheel body and the shell, and due to the difference in materials, the linear expansion values between the wheel body and the shell are not equal. The bearing gland is fixedly assembled on the housing, so during the working process, from low temperature, normal temperature to high temperature, the different expansion and contraction between the wheel body and the housing caused by temperature changes will lead to The change of the preload of the bearing will cause the fluctuation and instability of the dynamic friction torque of the bearing, which is not conducive to the normal operation of the bearing. The applicable temperature range of the control torque gyro is narrow, and it cannot be applied in some environments with large temperature differences.
