摘　　要：本文从裂纹齿局部刚度变弱的情况出发,分析裂纹故障齿轮的振动调制信息的传递性和频域分布的规律,并解决了齿轮故障诊断中的同类,异类故障的识别问题。Based on the weakening of local stiffness in crack gear, it is pointed out that phase modulation in meshing vibration is a characteristic reflecting the information of fatigue crack. The contribution and trasmission of fault information are investigated, then the recognizing problem of similar and dissimilar faults is solved.
