摘　　要：在齿轮的故障诊断中,振动信号常常夹杂着大量的噪声信号,表现出极大的非平稳性,采用基于小波变换的降噪方法,通过实例对齿轮振动信号进行降噪分析,收到了较好的效果。In gear fault diagnosis, much noise inteference always are existed in vibration singal, and displays the character of nonstable.Uses wavelet transform based on de-noising, and goes on de_noising annlysis of vibration singal for gear through art applied example.A good result are abtained using this method.
