摘　　要：滚动轴承运行中的打滑和保持架不稳定涡动会显著影响航天器飞轮系统的指向精度。提出了一种可应用于航天器飞轮系统的摩擦自供电轴承(KSTSPB),其利用保持架非导向间隙空间开发摩擦发电组件,利用保持架的周向及平面运动空间感知保持架的运动学行为,可实现保持架异常运动特征的实时监测。采用高速摄像并在保持架上标记识别点阵的保持架运动精准测量方法进行验证,结果表明,KSTSPB输出信号同时受到轴承速度和载荷的影响,其输出电压与涡动间隙指标之间呈负相关性,可实现对保持架打滑的定量分析以及保持架不稳定涡动的定性分析。The skidding and unstable whirling of cage during operation of rolling bearing significantly affect the directional accuracy of spacecraft flywheel systems.A kinematic-sensing triboelectric self-powering bearing(KSTSPB)for spacecraft flywheel systems is proposed,the non-guided clearance space of cage is used to develop triboelectricity generation module.The kinematic behavior of cage is sensed using its circumferential and planar motion space,enabling real-time monitoring of abnormal motion characteristics of cage.High-speed photography with cage marking,a method that accurately measures the cage motion,is used to confirm the KSTSPB’s ability to detect skidding and unstable whirling.The results show that the output signal of KSTSPB is affected by rotational speed and load simultaneously,and there is a negative correlation between output voltage and whirling clearance index.The quantitative analysis of skidding and qualitative analysis of unstable whirling of cage can be realized.
