Reasons and solutions for bearing heating during metal shredder operation

Metal shredder is a very common metal conveying equipment nowadays. It is mainly used to shred various metals to reduce its floor area, reduce transportation costs and facilitate recycling. It is a shredding equipment with good development prospects. Some customers reported that the bearings of the metal shredder heated up during use. So what is the cause of this situation? The following will explain to you how to solve such a situation.

The bearing is the core component of the shredder equipment. If there is a problem, it will directly affect the production efficiency. If the bearing seat is uneven, or the motor rotor and the shredder rotor are not concentric, the bearing will be impacted by the extra load, which will cause The bearing is overheated. If this happens, stop the machine immediately for inspection to avoid bearing damage.

Also, if the fit between the bearing cover and the shaft is too tight or the fit between the bearing and the shaft is too loose, the bearing will overheat. Once this happens, the bearing should be removed, the friction parts should be trimmed, and then reassembled as required. If the lubricating oil is too thick or too thin, it will also cause the bearing to heat up, because most of the heat generated by the bearing is taken away by the lubricating oil. When the lubricating oil is too thick, the fluidity will become poor and the heat will not be taken away in time. , causing the bearing to heat up. If the lubricating oil is too thin, there will be no way to form a protective film, and the bearing will rub directly, and the heat generated will become faster. Therefore, lubricating oil must be added regularly and in quantity according to the equipment instructions, in order to extend the service life of the bearings of the metal shredder equipment.
