Extension methods and installation of industrial SKF bearing life

In order to prolong the service life of SKF bearing, SKF bearing should pay attention to industry of maintenance, repair, in order to prevent accident arrangement to ensure the reliability of operation, improve the productivity and economy. To maintain the best conditions of mechanical operation of the corresponding operation standard, on a regular basis. Content includes monitor running status, supplement or replacement of lubricants, remove the check on a regular basis. As maintenance issues in the operation, with SKF bearing the rotation of the sound, vibration, temperature, the state of the lubricants and so on. 1, SKF bearing clean: remove the bearing maintenance and repair, the appearance of the first record SKF bearing, confirm the residual stock of lubricant, sampling inspection with lubricant, SKF bearing. Common use gasoline, kerosene as a cleaning agent. Tear open come down to the cleaning of SKF bearing, rough washing and fine washing, respectively in the container, put a metal mesh bottom first, make the bearing is not direct contact with dirt from the container. When cleaning, if rotating the SKF bearing with dirt, can injure the rolling surface of the bearing, should be pay attention to. In coarse clean oil, use a brush to remove grease, adhesive, after clean, roughly into fine cleaning). Fine cleaning, SKF bearing side rotation in the cleaning of oil, while carefully cleaned. In addition, the clean oil is always kept clean. 2, SKF bearing inspection and judgment: in order to judge whether the bearing of the removed can use, check after wash bearing. Check the raceway surface, rolling surface, cooperate with the state, the abrasion of cage, the increase of SKF bearing clearance and has nothing to do with dimension precision falling damage, abnormal. Non separation of small ball bearings, with one hand will support level, the inner ring spinning confirm whether smooth outer ring. Tapered roller bearing separation of SKF bearing, rolling body, the outer ring raceway surface can be respectively. Large SKF bearing can't rotate with the hand, pay attention to check the rolling element and raceway surface, cage, guard surface appearance, such as the importance of SKF bearing high must check carefully. 3, SKF bearing lubrication: the purpose of the rolling bearing lubrication purpose is to reduce the SKF bearing internal friction and the friction losses, prevent burning stick. ( 1) Reduce friction and friction losses. In the form of SKF bearing ring, rolling body and touch each other part of the retainer, prevent metal contact, reduce friction and wear. ( 2) Extend the fatigue life. SKF bearing fatigue life of rolling, in the rotation, good lubrication performance of the rolling contact surface, are extended. Instead, low oil viscosity, the thickness of lube film is not good, is shortened. ( 3) Discharge the friction heat and cooling. Circulation method to oil and so on can oil discharge by the friction heat, or by an external sound of heat, cooling. Prevent SKF bearing overheating, prevent aging oil itself. ( 4) Other: have to prevent foreign matter into internal SKF bearing, or to prevent rust and corrosion effect. Embellish of lubrication methods: SKF bearing slide method, divided into grease lubrication and oil lubrication. In order to make the SKF bearing function well, first of all, lubrication method to select suitable for conditions of use. If only consider lubrication and oil lubrication. However, grease lubrication can simplify the structure of bearing the surrounding of the special features, compare the pros and cons of grease lubrication and oil lubrication. 4, the installation of SKF bearing, SKF bearing installation is correct, affects the precision, life and performance. Therefore, design and installation of assembly department for SKF bearing to fully research. Hope to work in accordance with the standards for installation. Operation standard project usually is as follows: ( 1) , cleaning SKF bearing and the bearing connection parts; ( 2) And check the size of the interrelated parts and finishing; ( 3) , installation; ( 4) After installation, SKF bearing inspection; ( 5) , supply lubricant. 5, hope before the installation, just open the SKF bearing packing. General grease lubrication, cleaning, not directly fill grease. Lubricating oil, ordinary also don't have to be clean, but, instrument using or high speed bearings, etc. , to be washed with clean oil, remove rust inhibitor on SKF bearing. Remove the rust inhibitor of SKF bearing, easy to rust, so can't place. Also, has the bearing grease sealed, not directly use cleaning. 6, SKF 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. SKF bearing, cylinder hole is multi-purpose the pressure into the press and or multi-purpose hot charging method. Taper hole, installed directly on the taper shaft, or use the socket installation. 7, installed to the shell, clearance fit more commonly, outer ring had surplus quantity, usually with the pressure into the press and or have cooled after the installation of the shrink fit method. Use dry ice as coolant, shrink fit installation, the moisture in the air condenses on the surface of SKF bearing. So, need a good rust prevention measures.
