摘要
分析了输送机减速器齿轮的故障特点,通过减速器齿轮产生振动、噪声的机理研究,建立了齿轮振动模型。最后通过频谱分析和调制的方法实现齿轮的故障诊断。在频谱分析中,边频带提供了轮齿故障存在的重要信息,边频带的能量为调制后增加的能量,这部分能量的大小反映齿轮故障程度。
Firstly, the main fault of transporter retarder is the gear fauh through the fauh characteristic of analysis to transporter retarder gear. Secondly, describes the process of gear noise and vibration and sets up the model of gear vibration. Finally, the diagnosis detect of gear fault is achieved through spectral analysis and adjusting method. The sideband of spectral analysis provides the fault information and the adjusting energy, points out the degree of fault.
