How to correctly judge INA high temperature bearing damage breakdown maintenance problems - bearing knowledge

What about INA bearing damage to how to deal with. If the correct use of bearings, can be used to achieve fatigue life. But there will be unexpected injury prematurely, no ability to use. This early damage, and fatigue life, it is called the fault or the quality of the accident to use limit. Much due to the installation, use, do not pay attention on the lubrication, intrusion of foreign bodies from outside, to the shaft, shell heat affected study enough. About high temperature bearing damage status, such as: roller bearing ring, guard card injury, as a reason to consider, lack of lubricant, not suitable for, for the defect of oil discharge structure, the invasion of the foreign body, bearing installation error, the deflection of the shaft is too large, also can have these reasons. Therefore, only investigate bearing damage, the real reason is hard to come by injury. But, if you know the use of imported bearings machinery, conditions of use, bearing the surrounding structure, to get hold of before and after the accident, combined with several damage status and causes of bearing, can prevent the similar accident happen again. First of all, when we check INA bearings will be removed, photography and other methods shall be used to make appearance record. In addition, to confirm the amount of residual lubricant and lubricant sampling, and then high temperature bearing cleaning. Bearing cleaning divided into rough washing and fine washing, can be put in use at the bottom of the container and on the metal frame. Coarse, washing oil using a brush to remove grease or adhesive. If at this time in oil rotating INA bearings, pay attention to the rolling surface due to foreign bodies such as damage. Fine cleaning, slowly rotating bearings in the oil, must be carefully. Commonly used cleaning agent for neutral aqueous diesel or kerosene, according to the need to sometimes use warm lye, etc. No matter use which kinds of detergent, often should filter clean. Select material adequacy is still bearing failure analysis factors must be considered. The main task of the bearing failure analysis, which is based on a lot of background material, analyze data and failure forms, find out the main factors of bearing failure, so that the improvement measures are put forward, of extended high temperature bearing, avoid sudden INA bearing early failure. According to the bearing installation, use, maintenance, maintenance of technical requirements, the operation of the INA bearing on the load, speed, temperature, vibration, noise and lubrication condition monitoring and inspection, found that abnormal immediately to find the reason, adjustment, so that it is back to normal.
