纸机辊子振动检测中的典型频谱初探

The Analysis on Typcial Frequency Spectrum of Vibration Inspection for Paper Rolls

介绍了辊子振动检测中常见的故障及其频谱特征,对于辊子的动不平衡、包胶面斑马纹、其他旋转体共振、轴承故障、减速箱啮合不良、联轴器不对中6个常见问题的频谱特征以及分析,进行了较为详细地介绍。

The typical problems and frequency spectrum in roll vibration inspection was introduced in this paper,including roll dynamic unbalance,sizing cover’s zebra stripes,resonance of other rotators,bearing failure,bad meshing of gearbox,poor alignment of the coupling,etc.
