How to repair the bearing of the plastic shredder. The bearing is used in the plastic shredder to determine the relative movement position of the rotating shaft and the shaft box of the body, and the main component that plays the role of supporting and guiding. Due to the accuracy of the matching problem or the Overheating will occur when carrying a large load and wear. If it is not handled properly, it will directly affect the motor load and reduce work efficiency. In severe cases, the eccentricity of the spindle rotation will increase, which will affect the direct positioning of the moving knife and the fixed knife, thus affecting the discharging effect of crushed materials. Guangzhou Jiayin Machinery Xiao Zou tells you the solution:
(1) In normal maintenance, you must strictly follow the Jiayin Machinery Plastic Crusher Machine Maintenance and Cleaning Instructions for the bearing lubrication maintenance of the plastic grinder to prevent the quantity and quality of the added lubricant from affecting the machine, and the general amount of lubricant added Should be based on the size of the bearing space, it is best to occupy about 70%-80% of the bearing space, to prevent the increase of roller resistance caused by too much addition, and the phenomenon that too little will not achieve the lubrication effect.
(2) Check whether the two ends of the main shaft are at the same level through the main shaft rotor or observe whether the gap between the moving and fixed cutters is stable after adjusting the gap to determine whether the two shaft boxes are concentric, and avoid the inclination of the main shaft caused by the two shaft boxes. The damage that occurs due to uneven force during high-speed rotation is a factor of overheating of the bearing. In this case, you should stop the machine immediately and reposition the shaft box through the shaft box height adjustment bolt to extend the service life of the bearing .
(3) The effect of machining accuracy will also cause the bearing overheating in the matching of the bearing cover and the shaft. Since the matching of the bearing, the shaft box and the shaft adopts the tolerance of the base shaft, it may occur due to the different measurement methods used in the processing. Error, when the shaft and the shaft box fit too tightly, the pressure will increase, the friction between the outer ring and the inner ring of the bearing and the roller will increase, and heat will appear.
If your equipment encounters these kinds of problems, the production is slow, or the production is stopped and will not be repaired, you can directly contact the manufacturer to replace the machine in order to obtain a higher crushing efficiency.
