TIMKEN outer spherical bearing preventive maintenance common problems and countermeasures

Using rolling bearing all kinds of machinery, instruments, such as market performance has become increasingly strict, for TIMKEN bearing the required conditions, performance is also increasingly diversified. In order to from a large number of structure, size, choose the most suitable bearing, need study from various angles. When choosing bearing, generally, considered as a shaft of outer spherical bearing arrangement, installation, disassembly difficulty level, bearing allowed by the space, size and marketability of bearing, the general decided to bearing structure. Secondly, comparative study on various mechanical design life of the bearing and the bearing of a variety of different endurance limit bearing has to be decided. When choosing bearing, tend to be only consider the fatigue life of bearing, the aging by grease and grease, wear life, noise, etc. Also need to be fully research. Furthermore, according to different purposes, it is necessary to select precision, clearance, cage structure, grease, etc. , as a special design of the bearing. However, choosing bearing no certain order, rules, consideration should be given priority is to bearing the required conditions, performance, most related matters, especially the actual. Second checking TIMKEN bearing raceway surface of the rolling surface and on the surface of the joint venture and confrontation of the wear conditions of with and without damage and abnormalities in particular is to examine the raceway surface running track. Discriminant bearing can use again, to think outside the spherical 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 bearing of irregular 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: outer spherical bearing outside diameter or inner diameter with surface correction, changes the shaft seal form 1, peeling off: the rotary vibration fatigue spalling, replace the 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
