What stages can the bearing cage damage be divided into?

During the use of the bearing, it will be damaged or worn to a certain extent due to friction. Even the bearing cage is damaged during high temperature operation. So you know which stages of damage to the bearing cage can be divided into?

That is, the budding stage of the bearing begins to fail. At this time, the temperature is normal, the noise is normal, the total vibration speed and the spectrum are normal, but the total amount of peak energy and the spectrum are symptomatic, reflecting the initial stage of bearing failure.

The temperature is normal, the noise is slightly increased, the total vibration velocity is slightly increased, the vibration spectrum is not changed significantly, but the peak energy is greatly increased, and the spectrum is more prominent.

The temperature is slightly increased, the noise can be heard in the ear, the total vibration speed is greatly increased, and the frequency of the bearing fault and its harmonics and sidebands are clearly visible in the spectrum of the vibration velocity, and the noise level on the vibration velocity spectrum is obviously increased, and the peak is sharp. The total amount of energy is larger and the spectrum is more prominent than in the previous stage.

The temperature is obviously increased, the noise intensity is obviously changed, the total vibration velocity and the total vibration displacement are obviously increased. The frequency of the bearing fault disappears in the vibration velocity spectrum, and is replaced by a larger random broadband high-frequency noise level; the total amount of peak energy It grows rapidly and there may be some unstable changes.
