Before discussing the problem of bearing overheating, you must first understand the working principle of the universal crusher. The universal pulverizer mainly utilizes the high-speed relative motion between the movable sprocket and the fixed sprocket to make the pulverized material crushed by the combined action of tooth impact, friction and material impact. The structure of the fuselage is simple, firm, stable, and the pulverizing effect is good. The pulverized material can be directly discharged from the grinding chamber of the main machine, and the particle size is obtained by replacing the mesh screen of different apertures, and the machine is all stainless steel. The inner wall of the casing is completely finished to achieve a smooth surface, which changes the phenomenon of rough and powder accumulation on the inner wall of the previous model, and makes the production of medicines, food, chemicals and other products more in line with national standards, thus meeting the requirements of GMP.
There are many factors that cause the bearing to overheat. For example, when the two bearing blocks are uneven, or the rotor of the motor is not concentric with the pulverizer rotor, the bearing will be subjected to additional load shock, which will cause the bearing to overheat. In this situation, some experts said that it is necessary to stop immediately to eliminate the fault and prevent early damage of the bearing.
The bearing can extend the service life of the universal crusher, and the excessive, too little or aging of the lubricating oil in the bearing is also the main cause of the bearing overheating and damage. At this point, the operator needs to fill the lubricant quantitatively and on time according to the requirements of the book. In general, lubrication accounts for 70%-80% of the bearing space, too much or too little is not conducive to bearing lubrication and heat transfer.
In addition, the bearing cap and the shaft are too tightly fitted, and the bearing and the shaft are too tight or too loose to cause the bearing to overheat. If this problem occurs, when the device is running, it will emit a rubbing sound and a significant swing. At this point, the operator should immediately stop the bearing, remove the friction parts, and then reassemble as required. "In fact, the bearing will be prone to overheating after a long period of work. If such a phenomenon occurs, it is necessary to deal with it earlier to prevent damage." The manufacturer of the universal shredder said.
The author understands that the bearing temperature is too high is actually a common problem of the universal crusher, but also a major hazard. If the temperature rises faster, exceeding the standard will result in equipment outage or reduced load operation, which will cause damage to the equipment, reduce the service life of the bearing, and increase the maintenance cost of the equipment to affect the economic benefits of the enterprise. Therefore, it is necessary to quickly determine the fault and take appropriate measures to ensure that the universal crusher operates normally, continuously and safely.
In order to ensure the normal operation of the bearing, the operator needs to pay attention to the inspection work. Usually you need to check these points. Bearing quality: To check whether the grease has deterioration, agglomeration, impurities and other adverse conditions, this is an important basis for judging the cause of bearing damage. Check the bearing for bite and wear; check the smoothness of the inner and outer rings of the bearing, the rolling element, the surface of the cage, and whether there are defects such as cracks, rust, peeling, pits, thermal discoloration, etc., and measure whether the bearing clearance exceeds the standard; Whether there is wear, pit or peeling, if there is any situation, replace the new bearing.
Matching of the bearing: When the fit is too loose, the mating surface will produce relative sliding, that is, creep. Once creep occurs, it will wear out the mating surface, damage the shaft or the outer casing, and the wear powder will invade the inside of the bearing, causing heat, vibration and damage. Therefore, the operator should consider the nature, size, temperature conditions of the bearing load, and the various conditions of the inner ring outer ring.
Adjustment of the matching clearance of each part of the bearing: When the clearance is too small, the amount of oil will decrease, and the heat generated by the friction will not be taken away, and the temperature of the bearing will further increase; when the clearance is too large, the dynamic characteristics of the bearing will be changed, causing the rotor to operate. Unstable. In this regard, some experts suggest that the appropriate bearing clearance should be selected for the use of the universal crusher and the conditions of use.
In recent years, the application range of universal crusher has been expanding. It has not only been used in the pharmaceutical industry, but also has become an ideal crushing equipment in the chemical and food industries. However, like other pharmaceutical equipment, the universal shredder is also facing some problems. Among them, bearing overheating is a big problem that plagues customers.
