Prolonging the service life of the TIMKEN bearing rescue measures

1 installation: installation of TIMKEN bearing is correct, affects the precision, life and performance. Therefore, design and assembly department for the installation of the bearing be fully studied. Therefore, we should strictly according to the bearing when install the bearing installation steps to install, just in case bring damage to the bearing. 2 alignment, alignment: after the TIMKEN bearing installed, if not done carefully alignment, alignment can lead to bearing under other load, friction, and vibration. The use of these may accelerate fatigue and reduce the bearing life, and it might damage the other machine parts service life. In addition, the increase of vibration and friction could significantly increase the risk of energy consumption and premature failure. 3 monitoring: during the period of using, often should run of TIMKEN bearing of basic external condition monitoring, such as temperature, vibration and noise measurement and so on. These regular check will help identify potential problems and to prevent unexpected machine to suspend the phenomenon, make the production plan, improve plant productivity and efficiency. 4 lubrication again: in the process of operation, bearing requires correct lubrication again, perfect its performance. The method of bearing lubrication, divided into grease lubrication and oil lubrication. In order to make the TIMKEN bearing function well, the first thing to choose suitable for conditions of use, the purpose of lubrication method. If only consider lubrication and oil lubrication. 5 remove: when the TIMKEN bearing will reach its final use period, should be replaced. Although TIMKEN bearings can not be used, but properly unloaded the original bearing, replace new bearing in time, to extend the service life of new bearing can play a good role in promoting. ( 1) Within the bearing ring, outer diameter of save first on the defects existing in the parts ( Asymmetric type) Accurate measurement size, calculate the amount of one of the most refined ( To the finished product size deviation of grinding amount) M, and then in the center of the grinding of the parts when deviation ( Offset in the direction of the increased defect grinding amount) M / 2, the maximum offset, the relative increase grinding of defect, grinding. ( 2) Save for ring inner and outer raceway bearing ring grinding design benchmark for inside or outside, namely first grinding ( ) Diameter after grinding groove, within the circle, for example, if the groove is not symmetrical type of defect, need to accurately measure the parts inside diameter size, and calculate the maximum ground M and the maximum number of grinding groove defect in M1. When the M1 < M, inner ring center offset is needed when grinding inner diameter, maximum offset for the M1/2, namely in the inner diameter machining the inner race defect first relative increase grinding amount in advance, and then grinding the inner raceway, the defect will be point grinding, waste was saved. When the M1 p M, normal grinding mill not to drop, can be used according to the circumstance, 1) Save section about the method. The center drift method grinding is in guarantee parts hardness and carburized layer depth, under the premise of the overall offset is not completed in a migration of grinding, grinding, generally divided into several through migration test to grind - measuring - adjust offset - try grinding process repeatedly to complete, after being defects wear off, to find, normal grinding correction ovality. The low efficiency of this method, at the same time, request the operator has a higher level of technology, but in a single machine, single production, in this way to save the success rate is higher, do not delay production schedule. It has been verified by several years of practice effect is good.
