Analyzing the TIMKEN bearing import operation trajectory and loading method

TIMKEN bearing import a rotation, inner ring and outer ring raceway surface, with rolling body is rolling contact, as the dark side, thus orbit trajectory are attached to the raceway surface does not belong to abnormal, the change can be learned that load conditions, so in the case of remove the bearing, please keep close attention and observation on the surface of the raceway. If you look closely at orbit, will know that only bear radial load, bear the axial load of big, inherit the torque load, or extreme rigid in bearing box is not equal. Can check whether the TIMKEN bearing import added accidents such as whether the load and the installation error of kingdoms, the cause of bearing damage and be investigated for clues. If there is no error and can be used correctly, the bearing life before, but with a long period of time, in this case, the damage status to divest. On the other hand, there are early damage by accident, and yield to the early damage of use, as the reasons of early damage, not enough to use and the consideration on the lubrication and, in turn, and foreign invasion, the error of the bearing assembly and axis deflection of big, not enough research on shaft and bearing box, etc. ( 1) Due to the groove and the groove to make lubricating oil film thinning or damage, resulting in TIMKEN bearing import wear; ( 2) Because of the axis deflection when installation, load bearing hole with the partial load, bearing steel back hard spots and grease, shaft, or between a bearing stiffness is not enough to causes such as sliding bearing abnormal wear and tear; ( 3) Between foreign body into the bearing face, when foreign matter more than the minimum oil film thickness, the destruction of the oil film, lead to wear and tear; ( 4) Caused by too little oil, low oil pressure of lubricating oil is in short supply or interrupt, unable to establish normal oil film, shaft and bearing metal caused by direct contact, lead to wear and tear or fever; ( 5) Due to improper assembly, bearing and the bearing seat interference fit, the bearing cover, oil hole position deviation, skewness, shaft and bearing the centerline cause loose bearing, bearing and the bearing bore micro or incomplete contact, cause bearing wear and even surface spalling, etc. ; ( 6) The bearing shell interference degree. No interference between bearing steel back and bearing causes relative movement, causes the steel back of the flank wear; Interference measured ambassador TIMKEN bearing import inner hole shrink, not easy to form oil film, lead to premature wear or even killed. ( 1) Formulate scientific maintenance system. Preventive maintenance lubrication system, regularly check the oil pump, filter, cooler, comprehensive determination of the quality indexes of lubricating oil regularly, according to the ZhiHuan oil; ( 2) Choose appropriate lubricating oil, use a fine mesh filter; ( 3) Before assembly will thoroughly clean lubricating oil road, avoid into foreign body during installation. Ensure that the bearing seal and pipe seal in good condition, keep efficient working state of the oil filter; ( 4) Optimization of the groove and hole design, oil position, ensure the normal order of the oil, prevent leak; ( 5) Improve assembly process, choose the appropriate TIMKEN bearing import bearings interference quantity, completely eliminated the back and other assembly parts of the foreign body.
