During the operation of the equipment, users should pay special attention to the temperature rise of the bearing and the noise of the bearing part, and the abnormal should be dealt with as early as possible. Among them, bearing heating is one of the common failures of small mill, the following Shanghai Kunke Road and bridge machinery for you to specifically introduce the reasons leading to small mill bearing heating.
1. The bearing cover of the grinder is too tight with the shaft
Too tight or too loose fit between bearings and shafts will cause bearings to overheat. Once this problem occurs, there will be a grinding sound and obvious swing in the operation of the equipment. If this phenomenon occurs, the user should immediately stop the machine to remove the bearing, trim the friction part, and then reassemble as required.
2, bearing seat uneven
This situation will also affect the motor rotor and the crusher rotor different heart, so that the bearing is affected by the extra load, causing the bearing to overheat. In this case, it is necessary to stop the machine immediately for inspection and use after troubleshooting to avoid early damage to the bearing.
3, too much lubricating oil, too little, dirty deterioration
If the lubricating oil is not qualified, it is also one of the main reasons for the damage of the bearing overheating, therefore, the user should fill the bearing box regularly and quantitatively according to the standard, the general lubrication accounts for 70%-80% of the bearing space, too much or too little is not conducive to bearing lubrication and heat transfer. If it is dirty deterioration, be sure to clean the bearing box and then inject new lubricating oil.
