The so-called bearing burn injury state: INA bearings, roller wheels, the rolling element and cage sharp fever in the rotation until the discoloration, softening, deposition and breakage.
The main reason for cylindrical roller bearings burn due to poor lubrication of the bearing, you may use regular lubricant, or lubricant too much, too little, are incorrect.
(1) lubricant status
Lubricant sample to its pollution level to judge. More suitable for observation can not be close to cylindrical roller bearings or large bearing.
(2) voice recognition
Listening or listening stick attached to the shell can clearly hear the voice of cylindrical roller bearings, voice recognition of the need for a wealth of experience and therefore must undergo adequate training to be able to identify the INA Bearing voice and non-bearing sound.
(3) working temperature
Must be a continuous record of temperature. Fails, not only temperature, but also irregular changes. This method is limited with less change in the operation of state occasions.
Speed ??is too large. Clearance is too small. Water or other foreign body.
If the above two situations are not so is the shaft, bad precision of the bearing housing, shaft deflection. See here, I think everyone wants to know the solution, first of all, lubricants and lubrication methods, the election of the INA bearing lubricants, and the amount of, and correct choice of cylindrical roller bearings. Study with bearing clearance and preload, and improved seals. Check the shaft and bearing box accuracy. Of course, if your next expert, so that he's operating you follow the school the best!
