What are the reasons for the overheating of the crusher bearings.
(1) The uneven height of the two bearing seats, or the misalignment between the motor rotor and the crusher rotor, can cause the shaft to withstand the impact of additional loads, leading to overheating of the bearings. In this case, it is necessary to immediately shut down the machine to troubleshoot and avoid early damage to the crusher bearings.
(2) Excessive, insufficient, or aged lubricating oil in the bearings is also the main cause of bearing overheating and damage. Therefore, the crusher should add lubricating oil in a timely and quantitative manner according to the requirements of the user manual. Generally, lubrication accounts for 70% -80% of the bearing space. Excessive or insufficient lubrication is not conducive to bearing lubrication and heat transfer, and the bearing extends its service life.
(3) The fit between the bearing cover of the crusher and the shaft is too tight, and the fit between the bearing of the ultrafine crusher and the shaft is too tight or too loose, which can cause the bearing to overheat. Once this problem occurs, during the operation of the equipment, there will be a friction sound and obvious oscillation. The bearing should be stopped and removed, the friction area should be repaired, and then reassembled as required.
