How to correctly install SKF self-aligning ball bearing cope with failure problem

SKF bearing installation is correct, affects the precision, life and performance. Therefore, the design and assembly department for the installation of the bearing be fully research, according to operation standard for installation. Following a brief introduction of the installation of the bearings for you. Before installation, first you need to clean self-aligning ball bearing and the bearing connection parts, after check the dimensions of the interrelated parts and finish machining condition for installation. After installed bearing need further check and supply lubricant. Still need to pay attention to, before the installation, to open the bearing packing. General grease lubrication, cleaning, not directly fill grease. Lubricating oil, ordinary also don't have to clean, but the instrument with or high speed with SKF bearing, etc. , to be washed with clean oil, remove rust inhibitor) on the bearing. Remove the rust inhibitor of self-aligning ball bearing, easy to rust, so can't place. Also, has the bearing grease sealed, not directly use cleaning. 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. Cylindrical hole bearing, multi-purpose press pressure into, or multi-purpose hot charging method. Taper hole, installed directly on the taper shaft, or use the socket installation. 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 bearing. So, need a good rust prevention measures. Regular inspection or replacement parts, the need to remove the bearing. Usually shaft and bearing box almost all want to continue to use, SKF bearing also tend to continue to use. Structure design, therefore, want to consider removing self-aligning ball bearings, not damage the bearings, shaft, bearing housing and other components, as well as to the proper removal tool. Remove the interference fit ring, can only add tension on the ring, not by drawing roller ring. Through SKF bearing failure and degradation, performance status parameters to judge and predict the performance, reliability, and use bearing on the part of the abnormal situation, cause and degree of risk identification and judgment, decided to repair and improve the method of comprehensive technology. Therefore, bearing fault diagnosis technology is not a simple fault detection ( Or monitoring) Responsible for counting instrumentation of technology, also is not simple. Accurately and quickly and effectively to collect signals, data processing, manual or automatic identification and judgment. In order to confirm the repair cycle science, but also according to the mechanism of all kinds of fault, to fatigue, wear life necessary test and estimate. ( 1) And keep the bearing and its working environment clean. Even the eyes can't see the little dust, will also bring bad influence to the self-aligning ball bearing. So, keep the surrounding clean, dust from invading bearing. ( 2) , carefully use. In use for SKF bearing strong impact, will produce scar and creasing, become the cause of the accident. Severe cases, can crack, fracture, so must pay attention to. ( 3) And use the appropriate operating tools. Avoid to existing tools to replace, must use the appropriate tools. ( 4) And to pay attention to the corrosion of the bearing. Operating self-aligning ball bearings, sweat will become the cause of rust. Pay attention to the operation with clean hands, it is better to try to bring gloves.
