Medical instrument disinfection equipment bearing the how to check?

During the disintegration of 1, bearing the quality of the bearing box, first of all, check whether there is grease metamorphism, agglomerate, impurities such as adverse situation, it is the important basis of reason judge bearing damage. Second, 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. 2, with the bearing bearing installation bearing inside diameter and shaft, with the outer diameter and the shell is very important, when cooperate with too loose, mating surface will produce relatively sliding as the 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. Interference is too big, can lead to small outer diameter or inner circle diameter, reducing the bearing internal clearance. To choose the suitable for use with, want to consider the nature of bearing load, size, temperature condition, the rotation of the inner ring outer condition factors. 3 with the various parts of the bearing clearance adjustment bearing clearance hours, due to the shear friction loss in oil in the gap is too big, can also cause bearing heating, at the same time, the clearance after hours, oil amount decreased, too late to take away the heat generated by the friction, will further improve the bearing temperature rise. But the gap is too large will change the bearing dynamic characteristics of rotor caused by unstable operation. So the need for different devices and use choose to verify the condition of the bearing clearance.
