SKF miniature bearing operation of anomaly detection and elimination method

For as long as possible in good condition to maintain SKF bearing performance, maintenance, repair, in order to prevent accident arrangement to ensure the reliability of operation, improve the productivity and economy. To maintain the best conditions of mechanical operation of the corresponding operation standard, on a regular basis. Contents include, monitoring operation status, supplement or replacement of lubricants, remove the check on a regular basis. Miniature bearing damage and countermeasures, if the proper use of SKF bearing, can be used to achieve fatigue life. But there will be unexpected miniature bearing agent prematurely damage, not resistant to use. This early damage, as opposed to a fatigue life, use limit to the character of the called the fault or accident. 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. Damage status of miniature bearing, such as: roller bearing ring guard card, as a reason to consider, lack of lubricant, not suitable for, for the defect of oil discharge structure, foreign invasion, SKF bearing installation error, the deflection of the shaft is too large, also can have these reasons. ( 1) The method of observation. Rolling bearing with the naked eye observation, inner and outer raceway should not crumbling and serious wear and tear, and in a circular groove; All the roller surface should be no spots, cracks and peeling phenomenon; Cage should not loose, without damage, did not wear out, and the roller clearance but big. ( 2) The shooting method. Normal miniature bearing inner and outer race and rolling elements of clearance is 0. 005-0. 010 mm. For a phase of the miniature bearing, has been used with inner race for the axial shaking fingers clench, should have no obvious kuang dynamic noise. ( 3) The rotation method. With one hand holding the bearing inner race, another hand rotating seat, SKF bearing should be flexible rotation, and should not feel radial shaking. Check, should combine the above 3 kinds of methods, to facilitate the technical state of rolling bearing to make the right judgment. For taper roller SKF bearing, still should observe whether rolling body is located in the middle of the outer race, if you have moved forward, should not be more than 1. 5 mm.
