针对梅山烧结抽风机轴承座振动不稳定、轴向振动较大问题,采集了轴承座和轴承基础振动数据,介绍了基础松动、轴瓦磨损的振动机理。通过对所采集的振动数据的频谱、相位特征分析,论证了基础松动与导致轴高速运行时不对中的原因,并结合基础振动数据的差异现象,发现风机轴承座基础松动导致轴向力增大,进而造成轴瓦磨损。 Aiming at the vibration instability and large axial vibration of bearing seat of Meishan sintered exhaust fan, the vibration data of bearing seat and bearing foundation are collected, and the vibration mechanism of loose foundation and bearing wear is introduced. By analyzing the spectrum and phase characteristics of the acquired vibration data, the reasons for the misalignment caused by the foundation looseness and the high-speed operation of the shaft are demonstrated. Based on the difference of the basic vibration data, it is found that the axial force is increased due to the loosening of the base of the fan bearing , Resulting in wear bearing.
