INA angular contact ball bearing fever after operation maintenance factors must be considered

In order to check whether the installation is correct, must carry on the operation check. Small mechanical can rotate with the hand, to confirm whether to rotate smoothly. Check project has caused by foreign bodies, scars, creasing seized up, due to bad installation, installation of seat processing bad moment is not stable, because the clearance is too small, installation error, seal friction caused by the torque is too big, and so on. If there is no abnormal can start power operation. Bearing temperature, average according to the external temperature of the bearing. But using the oil hole directly measuring the temperature of the angular contact ball bearing outer ring more accurate. INA bearing temperature, from the beginning of the work gradually rise, usually 1 ~ 2 hours after the temperature stability. If the bearing installation, the temperature will rise sharply, abnormal high temperature. The reason such as lubricant, bearing clearance is too small, too much bad installation, excessive friction sealing device, etc. High-speed rotation, the choice of the ways of bearing structure, the lubrication error and so on is also the reason. To fully reach the bearing capacity of bearing, bearing inner and outer ring ( Or the axis of the thrust bearing ring back seat ring) The entire circumference of a circle, must be fully supported by solid and uniform, bearing surface can be cylindrical or conical surface, for in order to check whether installed correctly, check for running. Small mechanical can rotate with the hand, to confirm whether to rotate smoothly. Check project has caused by foreign bodies, scars, creasing seized up, due to bad installation, installation of seat processing bad moment is not stable, because the clearance is too small, installation error, seal friction caused by the torque is too big, and so on. If there is no abnormal can start power operation. The shaft of the bearing ring and seat, then applied a flat surface. To match the bearing ring surface processing, therefore, must meet the precision, and should not be any groove, hole or other shape of discontinuity. In addition, flange bearing circle must be securely fixed, in order to prevent the under the effect of load, the bearing ring rotation between the mating surface. 1, use the site: in order to check whether installed correctly, check for running. Small mechanical can rotate with the hand, to confirm whether to rotate smoothly. Check project has caused by foreign bodies, scars, creasing seized up, due to bad installation, installation of seat processing bad moment is not stable, because the clearance is too small, installation error, seal friction caused by the torque is too big, and so on. If there is no abnormal can start power operation. Bearing is suitable for predominantly radial load under the combination of radial and axial load, usually in two sets of angular contact ball bearing pair is used, should be mainly in car wheel hub, before and after active transmission parts, such as bevel gear, differential, reducer. 2, allows speed: under the correct installation, lubrication good environment, allowing for bearing limit speed of 0. 3 - 0. 5 times. Generally under normal circumstances, with 0. 2 times the limit speed for the most appropriate. 3, allows tilt Angle: INA bearings generally are not allowed to have tilted axis relative to the shell hole, if there are any tilt, no more than 2 '. 4, allow temperature: under normal load, and lubricant has a high temperature resistant performance, and abundant lubrication conditions, general bearing in - are allowed 30℃- Work under the temperature 150 ℃. Bearing to be removed after plans to continue to use, should choose the proper removal tool. Remove the interference fit ring, can only add tension on the ring, will never allow through transfer roller disassembly force, rolling element and raceway will be crushed. Lubricant is important not only for bearing, also for all of the angular contact ball bearings. But please note that the bearing should not add too much grease. And then replace the bearing lubricant. Use after xie used engine oil, engine oil lubrication bearing if possible, should be impregnated with fresh oil and let the machine in low speed rotation for a few minutes. As far as possible make the oil collecting residual pollutants, and then purging in addition to the oil. And the use of grease lubrication bearing in replacing grease, Joe used in addition to the device should be avoided with any part of the cotton material come into contact with the bearing. Because these residues fiber may wedged in between the scroll and damage, especially the application of INA bearings need more attention to this problem.
