Bearing working condition maintenance technology

Bearing in the process of its use showed a strong regularity, and the repeatability is very good. The normal high quality bearing ( Linear bearing) , at the beginning of the use of vibration and noise are relatively small, but there are some notorious of spectrum amplitude is small, may be because of some defects in the process of manufacturing, such as surface caused by burrs, etc. Movement after a period of time, maintain a certain level of vibration and noise, frequency spectrum is very single, only one or two times on the frequency. Rarely more than three times the power frequency spectrum on the bearing status is not random, enter not disorderly working period. Inheriting run late into use, the bearing vibration and noise began to increase, sometimes on the different sound, but the change of vibration increase is relatively slow, at this point, the bearing kurtosis value began with reaches a certain value. We thought, this time the bearing that is characterized by the early failure. For as long as possible in good condition to maintain bearing original function, maintenance, inspection, in order to prevent accident arrangement to ensure the reliability of operation, produce progress, economy. Maintain the premise of the scale of the mechanical operation of the corresponding best, on schedule. Content includes supervision and running condition, supplement or replacement of lubricants, remove the check on schedule. As test items in the operation, have bearing rotating the sound, vibration, temperature, lubricant state, etc. Bearing clean: remove the bearing test, the appearance of the first on-site, bearing, confirm the residual stock of lubricant, sampling inspection with lubricant, bearing. Common use gasoline, kerosene as a cleaning agent. Tear open come down to the bearing cleaning, rough washing and fine washing, respectively in the container, put a metal mesh bottom first, make the bearing is not direct contact with dirt from the container. Coarse when cleaning, if to spin bearing with dirt, can injure the move of the bearing surface, should be pay attention to. In coarse clean oil, use a brush to remove grease, adhesive, after clean, roughly into fine cleaning). Fine cleaning, bearing side rotation in the cleaning of oil, while carefully cleaned. In addition, cleaning of oil will always keep clean.
