Deep groove ball bearing, so energy saving and simple

The installation of deep groove ball bearing is correct, affects the precision, life and performance. Therefore, design and installation of deep groove ball bearing assembly department to fully research. Hope to work in accordance with the standards for installation. Operation standard project usually is as follows: ( 1) Check the size of the associated components and finish machining condition; （ 2) Installation; （ 3) Supply of lubricant. （ 4) Cleaning bearings and bearing related parts; （ 5) Check after installed bearing. Hope before the installation, just open the packaging of deep groove ball bearings. Lubricating oil, ordinary also don't have to be clean, but, instrument using or high speed bearings, etc. , to be washed with clean oil, remove rust inhibitor) on the bearing. General grease lubrication, cleaning, not directly fill grease. Also, has the bearing grease sealed, not directly use cleaning. Remove the rust inhibitor of bearing, easy to rust, so cannot be placed. When installed on the shell, clearance fit more commonly, outer ring have surplus quantity, usually use the pressure into the press and or have shrink fit method of cooling after installation. Use dry ice as coolant, shrink fit installation, the moisture in the air condenses the surface of the deep groove ball bearings. So, need a good rust prevention measures. Continue to run after late into use, the spherical roller bearings bearing vibration and noise began to increase, sometimes a different sound, but the change of vibration increase is relatively slow, at this point, the 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 deep groove ball bearings, 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 bearing fault has entered the late production, should be 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. In actual bearing fault diagnosis, therefore, once found late fault characteristic, fault judgment exist deep groove ball bearing fault, arrange inspection as soon as possible.
