FAG import bearing failure cause analysis of daily use

Replace bearing of vibration motor, reflected the effect is different, and must be used the same as the original model of bearing, and performance in this aspect also has the effect of the significance of better, which can reflect better results in this respect. First of all, from the following to introduce import FAG bearing installation. Replace new bearing vibration motor, must use the same as the original model of the bearings. 1) Bearing washed with kerosene, pressed into the bearing seat, fill toward the roller bearing outer ring shell 3 lithium base grease to two-thirds full, with clean hands evenly daub, mount bearing gland, use add bolt locking glue binding bolt pressure bearing gland; 2) Bearing for inside and outside the separable cylindrical roller bearings, bearing inner suit on the rotating shaft and should be in place; 3) The bearing seat is installed on the casing, such as grease oil injection hole, must be on the position. Use add bolt locking glue tighten bolts pressure bearing; 4) Inside and outside the eccentric block is installed on the rotating shaft and is in place, with the shaft key shaft key should be load within the keyway to eccentric block, shaft with ring on the rotating shaft; 5) Tight the bolt fixed eccentric block, adjustable eccentric block, make it reach to unload in front of the Angle position and tighten the fastening bolts. Above after completion of assembly, shaft should have certain axial string move; 6) On guard at the ends of the vibration motor, with screw fastening. FAG import bearings for the installation form of vibration motor and other aspects of performance are not change, the effect of and from different angles to consider also has a certain change, in the form of effect, slowly for all aspects of the installation is also have a certain understanding. Use factors mainly refers to install, use, maintenance, maintenance, repair and so on meets the technical requirements. Installation conditions is one of the primary factor of use factor, bearing is often caused by improper installation of a complete set of change the stress of bearing between various parts, bearing in the abnormal state run and early failure. According to the bearing installation, use, maintenance, maintenance of technical requirements, the operation of the 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. In addition, analyze the grease and the surrounding medium, the atmosphere quality inspection is also very important. 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. First of all, reasonable structure design and equipped with advanced, just can have a long bearing life. Bearing manufacturing generally go through forging, heat treatment, cutting, grinding and assembly, and multi-channel processing operations. The rationality of the processing technology, advanced, stability will also affect the service life of bearing. Which affects the quality of finished products bearing heat treatment and grinding process, tend to have a more direct relationship with bearing failure. In recent years the study of metamorphic layer of bearings working surface show that the grinding process and is close to the surface quality of the bearing. FAG bearings imported materials metallurgy quality were the main factors influencing the premature failure of the rolling bearing. As metallurgy technology, For example, the bearing steel vacuum degassing, etc. ) Progress, raw material quality is improved. Raw material quality factor in the bearing failure analysis share has declined obviously, but it is still one of the main influence factors of bearing failure. Select material adequacy is still bearing failure analysis factors must be considered. The main task of the imported FAG bearing failure analysis, it is based on a lot of background material, analysis data and failure forms, find out the main factors of bearing failure, so that the improvement measures are put forward, prolonging bearing, avoid premature failure of the bearing of the sudden.
