Bearing damage such as: roller bearing rings, ribs hurt, considered as factors, insufficient lubricants, are not suitable, for oil discharge structure defects, intrusion of foreign bodies, bearing misalignment, shaft deflection, also has these reasons coincide.
Stiffness of bearing with holes of different axis of adjusting the stiffness of the bearing housing must have sufficient, and on the same axis of the different axes of the bearing hole must remain strictly. In addition, possible diameter, avoidance of wedge rolling movement, and overload. Positioning positioning device, install the bearing should check that the snap ring is good, smooth shaft is smooth, no dirt and other impurities on the surface through the commissioning, bearing cap fixing bolt tightening process, continuous rotation angular contact ball bearings in rotating on its own should be positive, on the required torque screw bolts tight. In the process of tightening the shaft and bearing cover, continuous axis of rotation, the bearings should be on its own alignment. Light and flexible rotation of the bearing without the block, that has been found is, 2~3 required torque tighten the bearing cap bolts evenly. Propeller shaft intermediate support bearings should also be adjusted.
Appropriate operational clearance will contribute to closing the system study, Association did not take into account a variety of factors, large deviation between calculated and actual, in fact, SKF bearings for non-uniform temperature field of operation, and all three are interlinked.
Generally, SKF bearings, properly used, can use up to reach fatigue life. But there are accident prematurely damage, not in use. This early injury and fatigue life, is called the quality limits of failures or accidents. Result from installation, use, not paying attention on the lubrication from outside intrusion by foreign bodies, shafts, case study on thermal effect of inadequate.
SKF bearing work, there are many factors affecting his clearance, mainly temperature variation of angular contact ball bearings, centrifugal forces and serve. In the course of work, due to centrifugal force, combined with the effect of temperature, to vary the work clearance, sometimes with the three factors are not isolated, but connected. Therefore, in order to accurately reflect the actual work on the bearing clearance of the three effects in order to reasonably determine bearing clearance, to improve efficiency and running accuracy of the bearing.
