Bearing Cage and Raceway Wear, and Motor Drive End Bearing Pitting

Here is a vibration screen case, acceleration overall value of the coupling Horizontal 3H continues to rise slowly.The characteristic frequencies and harmonics of the bearing cage can be seen in the Envelope demodulation spectrum.

There is an impact of frequency interval in the acceleration time waveform of the drive end of the motor. The damage characteristic frequencies and harmonics of the inner ring of the bearing can be seen in the envelope demodulation spectrum of the motor drive end.

We can see the bearing cage and raceway of the coupling near the pulley side are worn and continuously deteriorated. The inner ring of the motor drive end bearing is pitted and peeled off, and the characteristics are stable.
