High precision bearing temperature causes and treatment methods

Bearing can prolong service life, and the bearing inner lubricating oil too much, too little, or aging is the main reason for the cause bearing overheating and damaged. At this point, the operator need to refill on time in accordance with the requirements for using books quantitative lubricating oil. In general, the lubrication of the bearing space of 75% 85%, too little or too much is bad for bearing lubrication and heat transfer. There are many factors that can cause bearing overheating, for example, when two bearing rugged, or with different heart crusher rotor motor rotor, additional load bearing down, causing bearing overheating. Encounter this situation, experts say, it is necessary to immediately stop the troubleshooting, preventing damage of bearing early. The matching of the bearing cover and shaft tight, bearing and shaft fit too tight or too loose will also cause bearing overheating. If appear this kind of problem, when the equipment operation, will send out the friction noise and clearly. At this point, the operator should immediately stop, remove the bearing finishing friction parts, and then carried out in accordance with the requirement to assembly. 'In fact, the bearing after working for a long time is easy to occur the phenomenon of overheating, if once appear, this phenomenon will early treatment to prevent damage. 'Said grinder manufacturer. In order to ensure the normal work of bearing, operators need to attach importance to check the work. Usually need to check these points. Bearing quality: to check whether there is grease metamorphism, agglomerate, impurities such as adverse situation, this is the important basis of reason judge bearing damage. To check the bearing have chewed and wear; Check the bearing inner and outer ring, rolling body, maintains its smoothness and presence of cracks on the surface of the discoloration, rust, peeling, pits, overheating defects, such as excessive measuring bearing clearance; Look for wear, pit shaft sleeve, peeling, if there is more than a new bearing should be replaced. Bearing with: when cooperate with too loose, mating surface will produce relatively sliding, namely creep. Once produced to wear matching surface, creep damage of shaft or housing, and wear into the bearing internal powder and fever, vibration and damage. As a result, the operator should consider the nature of the bearing load, size, temperature condition, the rotation of the inner ring outer conditions. Bearing parts fit clearance adjustment: when the clearance through the hours, oil will reduce, too late to take away the heat generated by the friction, the temperature of the bearing will be further increased; When the clearance is too large, will change the bearing dynamic characteristics of rotor unsteady operation. To this, expert proposal, to use condition and use conditions of bearing select suitable bearing clearance.
