Extending and safeguard IKO principle of rolling bearing stable running

One, from the perspective of using the guarantee stable operation should pay attention to the following: 1, the clearance should be appropriate, too big impact, is too small, poor lubrication, may burn. 2, rolling bearing and shaft neck surface quality and geometry must be strictly guaranteed. 3, improve the quality of lubrication, control oil pressure, temperature and flow rate, strengthen the oil filtration. 4, control the temperature of the diesel engine state, in the case of overheating too cold work will be unfavourable. Cold day, should be preheated before starting of diesel engine, with the hand cranking the engine oil into 5, the use of fuel and lubricating oil. Second, extend the IKO bearing using the three principles of A. Choose the IKO bearing type bearing with high load capacity selection of the bearing should be the price, or use of the rolling bearing in the load capacity is higher but more expensive, or just use ordinary while trying to extend the life. With a high bearing capacity, such as cylindrical roller bearing with crown, with a symmetrical roller spherical roller bearings, reinforced taper roller and ball type, ball groove busbar revised ball, or substitute IKO bearing 70000 CD series deep groove ( Single-row radial) Ball, these have high load capacity of bearing or improve the stress distribution state, or because of the number of rolling element may have higher fatigue life more. B。 Choose the right bearing size to make the size has been properly selected, must be precise or actual rolling bearing checking work load, speed, and operating temperature. Load effect on the life of the biggest, so the load while the most difficult to measure but be measured accurately as possible. When load measurement is difficult, can measure the actual consumption of the motor power, according to the transmission line, calculate and deduct the frictional power loss calculated until relatively close to the actual load. Calculated or measured load is larger, the fatigue life of IKO bearings can expect necessarily with greater amplitude decreases, and must try to remedy them. If the installation site allows, optional size of bearing products; , if any, on radial dimensions in a wider bearing under the condition of persons to be wide of the rolling bearing; If you can't use wide bearing, can convert the load bearing capacity is higher. C。 Choose the appropriate selection of materials of rolling 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 conditions, to improve the fatigue life of can expect several-fold. Use this kind of high quality steel, of course, made the cost of the bearing to choose higher load capacity bearing much more expensive than, but for difficult to close to and very difficult to install in the machine, or mines, tunnels in homework IKO bearings used in machinery, maintenance extremely difficult situation, sometimes still use must be considered.
