Bearing common faults and the method to deal with

Bearing common faults and if you choose the correct response bearing, and there are no errors using, can be used for a long time; In the right choice, used correctly, damage status to stripping. On the other hand, there are unexpected injury early yield to the early damage of use; As the reasons of early damage, not enough to use the consideration on the lubrication, foreign invasion, thus bearing installation error and axis deflection of large, on the shaft and bearing box, the accuracy of materials research, etc. General situation of overlap between these reasons more see. Bearing failure of general performance of two kinds: 1, bearing noise: bearing allows running noise slightly in the work, if you have any abnormal noise or excessive noise or sound hitched ring, suggests that the bearing failure. Bearing noise reasons: supporting bearing inner and outer surface wear. And the damage of the bearing and shell, bearing and shaft supporting relationship, lead to axis deviation from the correct position, bearing load are running to produce sound. When the bearing fatigue, its surface metal flake, can produce sound make bearing radial clearance increases. In addition, the bearing lubrication, forms the dry friction, and bearing broken etc all make abnormal noise. Bearing wear loose after kuang, maintains a looseness damage also can produce sound. 2, high bearing temperature: when the host is running, the installation of bearing parts allows a certain temperature, when the hands touch the host shell, should not feel hot as normal, conversely indicates that bearing temperature is too high. Bearing temperature reasons: lubricating oil quality does not conform to the requirements or metamorphism, lubricating oil viscosity is too high; Host assembly is too tight to make clearance insufficient: bearing assembly too tight; Bearing race on or inside the shell on the axle load is too large; Bearing cage or rolling body fracture, etc. In addition to the failure of method 1. Replacing bearings have to be carefully check on the new bearing, and the diameter of axle and bearing hole and the rotor of a detailed inspection; 2. Assembly and disassembly bearings, strictly implement repair technology, serious operation, avoid bearing damage caused by improper installation; 3. Fuel oil change in time, ensure the bearing working condition is always in good condition; 4. In the operation of the serious check, found the problems, timely eliminate.
