Discriminant IKO bearing high temperature problem to maintain the way care in use

High temperature bearing showed a strong regularity in the process of its use, and the repeatability is very good. Normal high quality bearings used in start, small vibration and noise are compared, but there are some scattered of spectrum amplitude is small, may be due to some defects in the process of manufacturing, such as appearance burr. Movement after a period of time, the vibration and noise to maintain a certain degree, the spectrum is a single, only one or two times the frequency. Rarely appear more than three times the power frequency spectrum, IKO bearing condition is very stable, into the stable working period. After going into the use of late, bearing vibration and noise increases start, sometimes presents the different sound, but the change of vibration increase is relatively slow, at this point, suddenly beginning bearing kurtosis value reaches a certain value. We thought, this time the bearing that is characterized by the early faults. At this time, the request of the high temperature bearing stop close monitoring, close attention to the change. Then, bearing kurtosis value and start landing fast, and is close to normal, and the significant increase in vibration and noise beginning, start to speed up its increase margin, when vibration beyond specification ( Such as ISO2372 specification) Beginning, its bearing kurtosis value also increases rapidly, when both above specifications, vibration and kurtosis value is beyond the normal ( Available kurtosis relative specification) When we think of IKO bearing has entered the late production trouble, should be timely maintenance equipment, change bearing. Swedish high temperature bearing show late fault feature to the present severe problem ( Common for bearing damage, such as holding shaft, burns, sand spallation, raceway, wear beads, etc. ) Time is not beyond a week, mostly equipment capacity is larger, the faster the speed, the shorter the distance of time. IKO bearing fault diagnosis, therefore, in practice, once found late fault characteristics, should be decisive discriminant bearing exist problem, arrangement of maintenance as soon as possible. Using the factor mainly refers to the device to adjust, use, maintenance, repair and other care can fit technology request. On the basis of bearing assembly, use, maintenance, the technical request, care about IKO bearing in operation to accept the load, speed, temperature, vibration, noise and smooth condition to stop monitoring and inspection, found that abnormal immediately to find the reason, stop adjustment, so that it is back to normal. First of all, the spindle spindle bearing during operation, to ensure smooth, robust and practical application situation and smooth oil regularly, not long continuous oil. So, about user enterprises, should choose a better, more appropriate smooth spindle oil. New special spindle oil can significantly progress smooth performance, extend the oil change period, increasing the using life of the spindle and IKO bearings, also has good anti-rust, anti-corrosion performance, etc. Second, by strengthening the nylon material to adhere to the aircraft bearing, using the temperature should be lower than 120 ℃, it is strictly prohibited to cooking oil to clean. In addition, the spindle when cleaning should pay attention to care, to avoid damage or scratch roller appearance. Try to eliminate the Swedish residue, high temperature bearing parts should be flush, internal cleaning residual oil suction bolsters approach is preferred. Should pay attention to prevent the dumping of type and make the cleaning dregs accumulation remain in bearing parts, invite IKO bearings produce the problem such as noise, wear failure.
