Study on Time Domain Analysis Method of Conical Bearing Fault Signal in Gearbox
As an important part of gear box of high-speed train,tapered bearing is of great significance for fault detection of dif-ferent service mileage or different maintenance grades on a regular basis.The tapered bearing states of different service states in gearbox are tested and four groups of parameters,namely effective value,kurtosis factor,pulse factor and margin factor,are ob-tained by time domain analysis.The results show that each parameter index of gear box bearing with service more than 1.2million km is higher than that of new bearing without service.It can be seen that the fault state of gearbox bearing can be preliminarily de-termined by using time domain analysis method,which provides a reference for further quantitative diagnosis of wear degree and fault type of bearing.
