摘要
研究了损伤齿轮的振动信号特征 ,齿轮的扭转振动信息中包含丰富的齿轮故障信息 .由于直接测量扭转振动信号比较困难 ,文中提出通过监测电机的定子电流对齿轮的扭振进行测量 ,通过对信号的分析提取故障特征 ,最终实现齿轮的故障诊断 .
This paper firstly studied the fault gear's character of vibration signal and it is shown thatthe information of gear's torsional vibration contains plenty faultmessages. Asitisvery difficultdirectly mea- suring torsional vibration,this paper presented a new method that can monitor gear's torsional vibration by measuring statorcurrent.Finally,the gear's faultcan be diagnosed by picking up signal characteristic.
