IKO bearing combination of abnormal operation maintenance common problem

Generally, combination bearings will heat up, since we started running in over a period of time, namely at a lower temperature ( Usually higher than the room temperature 10 ~ 40 degrees) In the norm. To the normal time, depending on the IKO bearing size, form, method of rotation speed, lubrication, imported bearing conditions around the change and different, generally it takes 20 minutes to several hours at this time. Bearing temperature warms up do not meet the normal and abnormal, can consider to the following reasons, moreover should stop and take the necessary measures as soon as possible. Temperature to keep the imported bearing the appropriate life and prevent oil deterioration is critical, such as advice: try to control in the high temperature condition ( Is 100 degrees commonly the following) Use the most ideal. The main reason of abnormal temperature rise of lubricating oil too much or too little. IKO bearing installation. Composite bearing internal clearance is too small, or too much load. Seal friction is too large. Lubricant. Cooperate with the creep. Followed by checking the bearing raceway surface, rolling surface and on the surface of the joint venture and confrontation of the wear conditions such as presence of damage and abnormalities in the special track is to examine the raceway surface movement. Discriminant bearing can use again, must think in combination bearing damage levels, mechanical function, primacy, operation premise, such as checking cycle back again choice. Strong metal sound 1, abnormal load: select the appropriate assembly clearance and 2, the assembly pretightening bad: improve the machining precision of the shaft, improve the installation method of 3, lubricants, lubricant rules complement or use appropriate caused the channel 1, foreign bodies, rust, indentation, scar: cleaning related parts, use a clean grease 2, channel peeling: fatigue wear, replace the irregular IKO bearing different sound 1, foreign bodies, intrusion: cleaning related parts, use a clean grease 2, clearance is too large, pay attention to the coordination and choose appropriate clearance 3, steel ball scar: steel ball fatigue spalling or foreign body card, replace the bearing too much abnormal temperature rise of 1, lubricants, reduce 2, lubricants, lubricants or not suitable for: add lubricant or choose a suitable lubricant 3, mating surface creep or sealing device is too big: combination of bearing outside diameter or inner diameter matching surface correction, changes the shaft seal form 1, peeling off: the rotary vibration fatigue spalling, replace the IKO bearing 2, assembly: improve the machining precision of the shaft, improve installation method 3, foreign bodies, intrusion: cleaning related parts, use clean lubricant grease leak too big change color 1, lubricants, lubricant 2, foreign bodies, invasion: cleaning related parts
