摘　　要：通过判断齿轮箱是否存在故障、推断齿轮箱故障源的特征频率和分析齿轮箱故障的种类3个方面应用研究,得出滚动轴承的故障占主导地位。如果出现旋转轴的频率及高次谐波或出现啮合振动频率Fm的高次谐波(如2Fm、3Fm),并且也有边频信号出现,可以推测是相应转轴频率上的滚动轴承出现故障。如果仅出现啮合振动频率Fm,并且有边频信号出现,可以推测是相应频率转轴上的齿轮出现故障。Through the application of three aspects of research type gear box fault source judging whether there is a fault, infer the gear box characteristic frequency and analysis of gearbox fault,obtains the roller bearing fault dominated. If the harmonic frequency and harmonics of the rotating shaft or the appearance of meshing vibration frequency of Fm（2Fm、3Fm）,and also have the side frequency signals appear, presumably is rolling bearing failure on the corresponding rotating shaft frequency. If only the emergence of meshing vibration frequency Fm, and side frequency signals appear, presumably is the corresponding frequency on the shaft gear failure.
