Bearing fault processing method, treatment and prevention! Bearing fault internal factors mainly refers to the structure design, manufacturing process and material quality and so on three major factors in determining the quality of bearing. Overall eccentric bearing fracture failure main reason is the defect and overload two factors. When the loads more than material strength limit fracture caused by parts called overload fracture. Overload reason mainly is the main engine failure or improper installation. Bearing parts of micro crack, shrinkage cavity, bubbles and large foreign impurities, overheating organizations and local burns and other defects during the impact overload or violent vibration will cause fracture in defect, known as defect fracture. It should be pointed out that the bearing in the process of manufacturing, for raw materials into the factory reinspection, forging and heat treatment quality control, process control by instrument whether there is a correct analysis of the above defects. But in general, usually bearing fracture failure mostly overload failure. The main task of the bearing failure analysis, is based on a lot of background material, the analysis of data and fault forms, find out the main factors of bearing failure, so that the improvement measures are put forward, extend the eccentric bearing, avoid bearing sudden early failure. Bearing in the work, because of the influence of the external or internal factors, change the original fit clearance, lower accuracy, and the change of 'killed' called clearance of failure. , large amount of the external factors such as interference of installation does not reach the designated position, temperature rise caused by the expansion, instantaneous overload, etc. , internal factors such as residual austenite and the residual stress in a state of flux and so on are the main cause of fault clearance change. 1, bearing damage. Check ball of ball bearing or bearing bush of ball bearing is damaged. If there is any damage should be repaired or replaced. 2, lubricating oil with impurity, too dirty, oil ring stuck or brand is wrong. Should check the reason stuck in oil, repair, when oil viscosity is too large, should change the lubricating oil. 3, bearing indoor short of oil. Should add grease with two-thirds of the oil level of oil chamber or add lubricant to the standard line. 4, in the rolling bearing grease jam too much, the eccentric bearing lubricating oil temperature too low or too high. Should remove excessive grease in the rolling bearing, or the oil indoor full of grease to 2/3. 5, bearing and shaft, bearing and end cover with too loose or too tight, too tight will make the whole deformation eccentric bearing, too loose prone to 'run set'. Bearings and shaft too loose when the journal can be coated metallic paint, the tight to processing; Bearing a loose end cover set close together with end cover, the tight to processing. 6, two of the motor end cover or didn't assembled bearing cover, it is usually not parallel, overall eccentric bearing is not in the correct position. The two end cover or stop bearing cover mouth flat, tighten the bolt. 7, belt too tight, too loose or bad coupling assembly. Adjust the belt elasticity; JiaoZheng coupling. 8 and maintenance in the wrong bearing type. To replace the right type of bearing as soon as possible.
