| Abstract: | The character of low speed and heavy-duty gear was analyzed,and the modulation theory of gear vibration signal was explained.The real problem that the low frequency fault information of low speed and heavy-duty gear case is easily submersed in low noise ratio.To this problem,put forward a opinion that fault character of speed and heavy-duty gear is extract pertinently by homomorphic filtering technology.The practices show that homomorphic filtering technology is effective to extract low frequency fault information in fault diagnosis of low speed and heavy-duty gear. |

| Keywords: | homomorphic filtering low speed and heavy-duty gear fault diagnosis |
