The problem of Bearing Overheating in crusher

When using the crusher, for the problem of bearing overheating, precautions: (1) two bearing pedestals are uneven, or the motor rotor is not concentric with the crusher rotor, which will make the shaft bear the impact of additional load, thus causing bearing overheating In this case, stop the machine immediately to eliminate the fault, so as to avoid early damage of the bearing (2) Too much, too little or aging of the lubricating oil in the bearing is also the main cause of the bearing overheating and damage Therefore, the lubricating oil shall be added on time and quantitatively according to the requirements of the use manual Generally, the lubricating oil accounts for 70% - 80% of the bearing space Too much or too little is not conducive to the bearing lubrication and heat transfer Bearings extend their service life (3) If the fit between the bearing cover and the shaft is too tight or loose, the bearing will overheat Once this problem occurs, there will be friction sound and obvious swing during the operation of the equipment Stop the machine and remove the bearing Trim the friction area and reassemble as required
