齿轮状态声信息流的识别法

Identification Method of Acoustic Information Flow of Gear State

根据齿轮噪声信息流的传播途径研制了固体声传声器和检测系统，并采用时域分离法分析处理固体声信息以确定齿轮的运行状态。实验结果表明，将此方法用于齿轮故障识别时，能确切提取反映齿轮工作状态的信息流。

According to the transmission way of information flow of gear noise ,we presentthe method of solid state acoustic detection, Noticeing transmission characteristic of the acoustic information flow, we develop and deduce the time domain seperating method. The experimental resultshows that the method can identify gear failure and also can extract the acoustie information flow ofwhich can correctly reflect,the gear moving characteristic , It is very useful to monitor the gear statecharacteristic.
