Abstract:
A new method to combine the wavelet analysis with short-time Fourier transform is presented to analyse the vibration signal of rolling bearing cage, extract the designated frequency composition corresponding to the bearing cage and judge the healthy status of the bearing cage accurately. The research demonstrates that the new method has unique advantages in identifying the defects of the bearing cages.
