摘　　要：利用齿轮啮合频率对轧机联轴器的故障机理进行了剖析,提出了综合利用实测的等间隔特征频率幅值和齿轮啮合特征频率对机械设备中联轴器故障诊断的方法,分析了实测的等间隔特征频率和齿轮啮合频率的判读。介绍了实测等间隔特征频率和齿轮啮合频率的算法及其故障诊断的过程。所提出和研究的频率图中实测的等间隔特征频率幅值和齿轮啮合频率吻合法能够针对联轴器故障振动特点进行有效的故障监测,进而在低速重载的旋转设备故障监测与诊断中即使没有明显的特征频率,也可以判断联轴器是否出现故障。The failure mechanism of the rolling shaft coupling is analyzed by using the gear meshing frequency, and the method of the fault diagnosis of the coupling fault is presented. The method of measuring the frequency of the frequency and the meshing frequency of the gear and the process of the fault diagnosis are introduced. The frequency amplitude and the frequency of the frequency of the gear mesh are measured in the frequency chart of the frequency map. And then in the low speed and heavy load of the rotating equipment fault monitoring and diagnosis, even though no obvious charueteristic frequency, it can also determine whether the failure of coupling.
