Abstract

Planetary gearbox ,due to the timevarying property of the vibration transmission path, leads to the complex modulation sidebands in its vibration signal spectrum, which contains abundant fault informations of the gearbox. A special narrowband demodulation method for the planetary gearbox was put forward, combining the synchronous average and narrowband demodulation or the vibration separation signals of the planetary gearbox. The window interception of the vibration signal was made, and according to the teeth order characteristics of the gear meshing of the planetary gearbox, the vibration signal of a single gear was reconstructed by the splicing of the window interception signals, to overcome the influence of the variation of the transmission path. The time domain synchronous averaging of the vibration separation signals, was utilized to improve the signaltonoise ratio. The narrowband demodulation for the average vibration separation signals, was carried out, and finally, the fault characteristics and fault location of the planetary gear box were extracted. Through the experimental analysis, it was verified that the method can effectively extract planetary gearbox fault characteristics.
