To prolong the cycle TIMKEN angular contact ball bearing maintenance - bearing knowledge

To make the TIMKEN bearings and keep its long-term performance into full play, must earnestly to do regular maintenance ( Regular inspection) 。 Through proper periodic inspection, do early detection of fault, prevent accident arrangement is very important to increase productivity and efficiency. 1, clean angular contact ball bearing will be removed to check, use methods such as photography first and then record the appearance. In addition, to confirm the amount of residual lubricant and lubricant sampling, and then clean the bearing. A, bearing cleaning divided into rough washing and fine washing, can be put in use at the bottom of the container and on the metal frame. B, rough washing, oil using a brush to remove grease or adhesive. If at this time in oil turn the TIMKEN bearings, pay attention to the rolling surface due to foreign bodies such as damage. C, fine cleaning, slowly rotating bearings in the oil, must be carefully. Commonly used cleaning agent for neutral aqueous diesel or kerosene, according to the need to sometimes use warm lye, etc. No matter use which kinds of detergent, often should filter clean. After cleaning, immediately on the TIMKEN bearing coating anticorrosive oil or antirust grease. 2, examination and judgment to judge removed angular contact ball bearing can be reused, to inspect the dimension precision, rotating accuracy, internal clearance and mating surface, raceway surface, cage and seal rings etc. About the test results that can be used by bearing the judgement or master of bearing. Judgment standard according to the mechanical properties and important degree and inspection cycle. If you have the following injury, bearing shall not be used again, must be replaced. 1) Bearing parts of rupture and defects. 2) The raceway surface material on the surface of the rolling strip. After bearing installed, if not done carefully alignment, alignment may cause angular contact ball bearing under other loads, 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, the basic conditions for monitoring during the period of using, often should run of TIMKEN bearing of basic external condition monitoring, such as temperature, vibration and noise measurement, etc. 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, again the lubrication 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 bearing function well, first of all, to choose suitable for conditions of use, the purpose of lubrication method. If only consider lubrication and oil lubrication. But there are grease lubrication can simplify the structure of bearing around specialty. 5, unloaded when bearing will reach its final use period, should be replaced. Although bearing can no longer be used, but properly unloaded angular contact ball bearing, replace new bearing in time, to extend the service life of new TIMKEN bearing can play a good role in promoting. First of all, the use of appropriate tools unloaded method will help prevent for other machine components of the damage, the second, is not correct to unload the technology may cause harm to the operator.
