Motorcycle sprocket vibration time synchronous averaging method

Motorcycle sprocket vibration time synchronous averaging method:

This method is used for fault diagnosis of motorcycle sprocket, the gearvibration signal can be extracted from vibration signals of interest in total,and the vibration signal and noise of other components are all removed,thereby greatly improving the signal to noise ratio. The inner ring of the rolling bearing, the outer ring or a rolling body damage, the rotation frequency of the vibration signal fault characteristic frequency and shaft is different, therefore, time synchronous averaging method can alsodistinguish the vibration caused by the bevel gear fault vibration andbearing failure. If you want to get the vibration signals of a pair of meshing gear, is only the reference pulse frequency is equal to the gear shaft speedcan be.
