In order to ensure a high actual results, the surface of the shaft and hole and self-aligning ball bearings to match the roughness should be as small as possible, so that these measurements, should be in the cylindrical bearing hole, shaft and bearing seat hole corresponding surface, respectively, on both sides of the assembly chamfer near, show that the two mark, so the maximum the deviation of actual assembly direction, so that the maximum deviation of both matching deviation at the same direction, so that the assembly, can be partially offset by both parties.
Two direction sign is designed to compensate the deviation, can be considered, even if the rotation is supported at both ends to improve its precision, two bearing seat hole and both ends of the coaxial magazine part error elimination have also but. The implementation of measures such as surface, sand blasting, diameter slightly larger than the first column precision plug-in Kong Dusai, surface hardening, it can increase the accuracy of. Accuracy provided a lot of help for the stable operation of machinery, can reduce the appearance of adjustable ball bearing machinery fault rate, so we should try to improve the accuracy when installing INA bearings.
Lubrication on the fatigue life of ball bearings and friction, wear, vibration, temperature has an important influence on no lubrication INA bearing normal will not work, reasons for the failure of the self-aligning ball bearing shows that around 40% of bearing damage related to poor lubrication, so the excellent lubrication of the bearing is reduced minor ball bearing friction and wear of effective measures, in addition to the bearing lubrication also plays a role in heat dissipation, anti-rust, sealing, ease the impact, to ensure that the lubricant cannot expired selection to the right.
The reason of self-aligning ball bearings because of their quality and external conditions in the use process, its carrying capacity, the rotating precision and wear resistance will change, performance index when the self-aligning ball bearing is lower than the requirements and can not work normally, INA bearing failed even failure, once the self-aligning ball bearing failure after the accident, machine, equipment will be stopped, functional loss of abnormal phenomenon, therefore need to find out the causes in the short term, and take corresponding measures.
For the self-aligning ball bearings in good condition to keep the due performance and long-term use, must carry on the inspection and maintenance of INA bearings, inspection and maintenance is very important to the prevention of fault, to sound, vibration, temperature and lubricant rolling focus on examination of self-aligning ball bearings in operation.
