论述滚动轴承的振动监测与故障诊断的原理、方法和系统。采用振动监测系统对滚动轴承进行巡回在线监测 ,发现故障后发出声光警告 ,然后自动转入诊断模块 ,用共振解调法进一步判断故障发生部位及其趋势等。附图 4幅 ,参考文献 3篇。 Discusses the principle, method and system of vibration monitoring and fault diagnosis of rolling bearing. The vibration monitoring system is used to carry out on-line monitoring of the rolling bearing circuit. After the fault is found, the system sends an audible and visual warning and then automatically switches to the diagnostic module to further determine the fault location and its trend with the resonance demodulation method.
