摘　　要：齿轮磨损故障对机械设备工作影响较大。利用声发射检测技术对齿轮运行状态进行实时监测,并通过Hilbert-Huang变换(HHT)方法对采集的数据进行分析处理。通过对比正常齿轮与故障齿轮的经验模态分解图、Hilbert谱,得出齿轮磨损故障的频率特征,证明声发射检测方法可以有效地检测到齿轮磨损故障,对齿轮故障诊断具有重要意义。The mechanical equipment work is greatly influenced by gear wear failure.The acoustic emission detection technology is used to monitor the real-time state of gear running.Hilbert-Huang transformation（HHT） is used to analyze the collected data.Comparing the normal gear and the fault gear with their empirical mode decomposition and Hilbert spectrum,the frequency characteristics of the gear failure are obtained.So acoustic emission method is the effectively detect means for the gear wear failure and is great importance to the gear fault diagnosis.
