SKF universal joint bearing fault causes

Universal joint bearing failure of motor fault in a bigger loss caused by damage of bearing is quite serious, the running motor is inherently a variety of sound and vibration, if found to have o blow, sliding sound, metallic sound, temperature increased significantly, compared with the usual operation of both feel diverge from, it is necessary to find out the reason, is the result of the SKF bearing? Or other malfunction. Bearing motor bearing maintenance mainly rely on timely regular replacement of grease, motor bearings for rolling bearing. Rolling bearing grease lubrication, lubrication purpose is to prevent metal to metal in the rolling and sliding bearing surface direct contact and prevent corrosion on the surface of the bearing. Motor bearings with grease needs regular replacement of fresh grease, and keep the motor rolling bearing operating temperature lower than 90 ℃, to achieve the desired grease to normal life. Small local SKF bearing raceway and rolling element may be damaged. In the operation of local damage due to operation or installation errors. Rolled bearing damaged parts will produce a certain vibration frequency. Vibration frequency analysis can identify the damaged bearing parts. The vibration behavior of application places in many applications, the bearing stiffness with the surrounding the stiffness of the same structure. Due to this feature, as long as the correct choice bearing ( Including the preload and clearance) And its application in the configuration, it is possible to reduce the application of vibration. Universal joint bearing of rolling bearing itself does not produce noise. Often feel bearing noise 'is in fact bearing directly or indirectly, with the surrounding structure vibration sound effects. In general. Noise intensity is not big. Such as rolling body outer ring with faint uniform rolling sound ( Test listen to sense light) The normal operation, universal joint bearing. Such as hear the abnormal sound, SKF bearing a homogeneous and continuous 'hissing' sound, the sound is produced by the outer ring, roller rotation and, contains a metal has nothing to do with the speed of irregular vibration noise. Average performance for add lubrication oil in bearing grease quantity is not enough, should distinguish the cause and treatment. Hear the screams of approximate whistle, mingled with the 'goo importance goo importance' rolling roller, improper selection shows a lack of grease or oil should be clean, supplement or replace the appropriate grease. Bearing running continuously in a 'rush' of a homogeneous periodic 'wow' sound, the sound is due to the rolling element and the inner and outer ring raceway there scars, grooves, rust spot. Sound cycle have corresponding relations with the speed of universal joint bearing, SKF bearing for replacement. SKF bearing ring with adjacent components are likely to match the shape and deformation. If there is a deformation, the waviness on bearing ring of the self-contained parts or close coordination between the shaft. In the operation of the vibration may be produced. Therefore, the bearing and the shaft are machined to the required tolerance is very important.
