| 摘 要： | 为进一步研究陶瓷轴承摩擦性能,通过混合陶瓷球轴承与同型号同精度钢制球轴承的对比试验,分析高速精密陶瓷球轴承应用于卫星姿控飞轮的可行性,试验结果表明:陶瓷球轴承的静态摩擦力矩、高速运转下的温升和摩擦功耗均小于钢制球轴承;陶瓷球轴承加速度振动性能和钢制球轴承相当;速度振动性能值在低频和中频段陶瓷球轴承小,但在高频段速度振动值大,飞轮工作转速远低于高频段所对应的转速,陶瓷球轴承的综合振动性能优于钢制球轴承;将陶瓷球轴承应用于小卫星调姿飞轮中,可以极大地提高飞轮的角动量/质量比,减轻系统质量,从而获得更大的功能密度.

| Abstract: | To further study the friction characteristics of ceramic bearing,differences of friction characteristics between the hybrid ceramic bearing and the all-steel bearing were investigated by experiments using the basic friction tester under low-volatility grease lubrication.The results show that the static friction torque,the temperature rise and the friction power loss at high-speed running of hybrid ceramic bearing are less than those of all-steel bearing.The acceleration vibration performance of both bearings is almost the same.The value of velocity vibration of the hybrid ceramic bearing is much smaller than that of the all-steel bearing at low and intermediate frequency,while the result is reverse at high frequency.The application of ceramic bearing to the momentum wheel of satellites can improve the angular momentum-mass ratio of wheel,reduce the mass of the system and obtain better function density. |
