How to extend a FAG bearing life three principles - bearing knowledge

( 1) Choose the FAG bearings with high load capacity model selection should consider the price of bearing FAG bearing, or adopt the load capacity is higher but more expensive FAG bearing, or just use ordinary FAG bearing and the other tried to extend its life. USES a high load capacity FAG bearings, such as crown of cylindrical roller bearing, spherical roller bearing with symmetrical roller, reinforced taper roller bearing and ball bearing, ball groove busbar revised ball bearings, or substitute the FAG bearing of 70000 CD series deep groove ( Single-row radial) Ball bearings, which have high load capacity FAG bearings or for improving the stress distribution state, or because of the more the number of rolling element may have higher fatigue life. ( 2) Choose appropriate FAG bearing size to make the FAG bearing size has been properly selected, must be precise or real FAG bearing checking work load, speed, and operating temperature. Load to FAG bearing life most affected, so load are the most difficult to measure but they can be measured accurately as possible. When load measurement is difficult to measure the actual motor power consumption, according to the transmission line, calculate and deduct the frictional power loss calculated until relatively close to the actual FAG bearing load. Calculated or measured load slants big, FAG bearings can expect the fatigue life of inevitable with larger amplitude decreases, and must try to remedy them. If the installation site allows, optional size a FAG bearings; , if any, on radial dimensions in a wider FAG bearings under the condition of persons to be wide FAG bearings; If you cannot use a wider FAG bearings, FAG bearings can convert high load bearing capacity. ( 3) Choose appropriate FAG bearing material selection FAG bearing material also want to consider the price of it, and when to use the vacuum smelting or electroslag remelting steel, attention should be paid to must make WanShanHua lubrication condition, can we improve the exponentially FAG bearing fatigue life can be expected. , of course, by using this kind of high quality steel FAG bearing should choose load capacity is higher than the cost of FAG bearing much more expensive, but for in the machine is difficult to close and extremely difficult to FAG bearing, installation or mines, tunnels in operation FAG bearings used in machinery, maintenance extremely difficult situation, sometimes still use must be considered.
