TIMKEN bearing installation affecting the service life of bearing

TIMKEN bearing installation is correct, affects the precision, life and performance. Therefore, design and assembly department for the installation of the bearing be fully studied. Hope to work in accordance with the standards for installation. Operation standard project usually is as follows: ( 1) Check the size of the associated components and finish machining condition; ( 2) Installation; ( 3) Supply of lubricant. ( 4) Cleaning TIMKEN bearing and TIMKEN bearing associated parts; ( 5) After installed the TIMKEN bearing inspection; Hope before the installation, just open the TIMKEN bearing packing. Lubricating oil, ordinary also don't have to be clean, but, instrument or high-speed import with TIMKEN bearing etc, to be washed with clean oil, remove rust inhibitor on the TIMKEN bearings. General grease lubrication, cleaning, not directly fill grease. Also, has the bearing grease sealed, not directly use cleaning. Remove the rust inhibitor of TIMKEN bearings, easy to rust, so can't place. When installed on the shell, clearance fit more commonly, outer ring have surplus quantity, usually use the pressure into the press and or have shrink fit method of cooling after installation. Use dry ice as coolant, shrink fit installation, the moisture in the air condenses on the surface of TIMKEN bearings. So, need a good rust prevention measures. TIMKEN bearing installation method, because the bearing structure, cooperate, conditions vary, in general, as more as the axis of rotation, so the inner circle need interference fit. Taper hole, installed directly on the taper shaft, or use the socket installation. TIMKEN bearings, cylindrical hole multi-purpose press pressure into, or multi-purpose hot charging method. TIMKEN bearings after installation, need careful adjustment, straightening can lead to TIMKEN bearings under other loads, friction, and vibration. This could accelerate fatigue and reduce the life span, and it might damage the other machine parts service life. In addition, the vibration and friction could significantly increase the risk of and premature failure. In the process of operation, bearing requires correct lubrication again, perfect its performance. TIMKEN bearing lubrication method, divided into grease lubrication and oil lubrication. In order to make the TIMKEN 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 TIMKEN bearing specialty of surrounding structures. When TIMKEN bearing will reach its final use period, should be replaced. Although bearing can no longer be used, but remove the original TIMKEN bearings, correctly and timely replacement of new TIMKEN bearings, to extend the service life of new 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. In use process, often should run of TIMKEN bearing of basic external condition monitoring, such as temperature monitoring and measurement of vibration and noise, etc. Make production plan, improve plant productivity and efficiency.
