Test on static and temperature characteristics of gas foil bearing

摘要

摘要: 建立箔片气体径向轴承静态特性和温度特性测试实验台,通过变载荷和变转速两种实验方式对轴承起飞转速、摩擦阻力矩和轴承温升进行测量，研究分析轴承静态特性、温度特性与载荷、转速之间的关系.实验结果表明：在启停阶段，由于没有形成气膜，箔片气体轴承的摩擦阻力矩会出现较大的峰值，但当达到某一特定转速（起飞转速）后，摩擦阻力矩会迅速下降到某一极小值,并且起飞后的稳态轴承转矩会随载荷和转速的增大而增加.稳定状态下的轴承温度会稳定在某一值且相对于室温的温升极小，而且随着转速、载荷的增加近似于线性增大.

Abstract: A test rig was set up to check the static characteristics and temperature characteristics of the foil gas radial bearing. After applying different load and speed on the bearing, the bearing take off speed, friction moment and bearing temperature were measured respectively. Then, the bearing static characteristics and temperature characteristics in different load and speed were analyzed. Results showed that, since there was no gas film in the start-stop stage, the foil gas bearing friction torque peak appeared larger, but when reaching a certain speed (take off speed), the friction torque would drop to a pole small value, and the steady-state after take-off speed bearing torque increased with the applied load and speed. In addition, the bearing temperature stabilized at a certain temperature in the stable operation stage. The bearing temperature rise was very small and increased approximately linearly with the speed and load.
