摘　　要：首先对频谱分析方法和时频分析方法的原理进行了简要的介绍,再根据频谱分析与时频分析的特点,依据实验对齿轮箱所设置的3种工况,进行了正常运行下与断齿、外圈断裂故障运行下的三种状态进行了对比,转速为900r/min。结果表明,此方法能够得到比较理想的效果。Briefly introduced the frequency spectrum analysis method and time-frequency analysis, according to the spectrum analysis and time-frequency analysis characteristics, based on the experiment on gear box set by three kinds of fault, under the normal operation and break tooth ring fracture failure under the operation of the three states are compared, speed for 900 r/min.The results show that this method can get ideal effect.
