SKF roller bearing regular inspection of law adjustment method

To examine the roller bearing on a regular basis, it is important to be in the best condition to maintain the bearing work, can also be found the problem. About SKF bearing matters that should be paid attention in use and related knowledge. First of all, we have to stress is that it is important to keep the roller bearing lubrication and clean. So when we inspect the bearing before, should first clean the surface of bearing, and then remove the perimeter of the SKF bearing parts. Everyone should pay attention to, oil seal is very fragile parts, so in check and need to be careful, when disassembling do not excessive force, so as not to cause damage to parts. Then carefully check roller bearing oil seal and its surrounding parts, if has presented the adverse symptoms, be sure to replace, and bad seal will result in bearing damage, make the roller bearing cloud caused by abnormal equipment downtime. Second, we will also examine roller bearing lubricant. Lubrication is very important, not for the bearing, also for all the import bearings. Note, however, SKF bearing shoulds not be too much grease. About the check method of roller bearing lubricant: with little lubricant in friction between two fingers, and if the presence of pollutants, can be felt; Or in the back of a thin layer of lubricant, then seal of inspection. And then replace the roller bearing lubricant. Using the oil lubrication of roller bearings after xie used engine oil, if possible, shall 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. Note: the oil before use it's best to filter it. While the use of grease lubrication of SKF bearing in replacing grease, Joe used in addition to the device should be avoided with any part of the joint Angle of cotton into the bearing. Because these residues fiber may wedged in between the scroll and damage, especially the application of small bearing more need to pay attention to this problem. Movement after a period of time, maintain a certain level of vibration and noise, frequency spectrum is very single, only one or two times the frequency. Rarely appear more than three times the power frequency spectrum, roller bearing condition is very stable, steady working period. Continue to run after the late into use, SKF bearing vibration and noise began to increase, sometimes a different sound, but the change of vibration increase is relatively slow, at this point, the angular contact ball bearing kurtosis value began suddenly reaches a certain value. We believe that the bearing is characterized by the early failure. At this time, requires to closely monitor the SKF bearing, pay close attention to the change. Since then, bearing kurtosis value began falling fast, and is close to normal, and significant increase in vibration and noise, it began to accelerate the increase, when the vibration more than standard ( Such as ISO2372 standard) , its bearing kurtosis value also began to increase rapidly, when more than vibration standard, and kurtosis value is more than normal ( Available kurtosis relative standard) When we think of roller bearing fault, has entered the late need to timely maintenance equipment, replace the bearing. Late show bearing fault feature to severe fault ( For bearing damage, such as holding shaft commonly, burns, sand spallation, raceway, wear beads, etc. ) Most of time not more than a week, the bigger the equipment capacity, the faster the speed, the shorter the time interval. Therefore, in actual SKF bearing fault diagnosis, once found late fault characteristics, should be decisive judgment is bearing fault, arrange inspection as soon as possible.
