Avoid KOYO cause vibrations in the process of rolling bearing operation method

Rolling bearing vibrating screen is more difficult to control the main vibration source, because of the vibrating screen is to rely on a lot of exciting force to maintain the work of the limit speed and friction coefficient of bearing, so KOYO bearing by radial force is very big, vibrating screen in the process of work, a lot of exciting force will cause the elastic vibration of bearing system. If bad lubrication, can produce large friction bearing temperature rise too high, thermal expansion is too large, the radial clearance is significantly reduced, exacerbating the friction, temperature rise further improved. Bearing locking methods of general can be divided into two kinds: 1. Enclosed screw bearing peg just put the extension in the inner ring fasten the screw on the local, can put the bearing seat is fixed, peg screw with hex wrench can lock. Please select a size appropriate hex wrench. 2. With fair locking sleeve bearing fair locking sleeve has a concave KOYO bearing vibration and temperature, the sunken place instead of blastholes in fair, in the inner ring of the bearing is a local for the fair. The fair first sleeve on the inner ring is defined, in the direction of the axis of rotation, hasten to turn the fair bearing sleeve know card so far, with hexagonal wrench tightly lock screw. Bearing and eccentric system consisting of a vibration system, can be regarded as a single degree of freedom system. Rolling bearing drive shaft and driven shaft system resonance frequency of a certain value, if a certain vibration frequency and resonant frequency, the resonance occurs. In addition, due to the eccentricity is centrifugal force, so will produce bending vibration of material factors affecting the service life of bearing, if speed close to critical value, the resonant bending. From peeling, indentation, rust, crack and wear will be reflected in the bearing vibration measurement, bearing vibration damage of bearing is very sensitive, so the bearing through the use of special KOYO bearing vibration measuring device ( Frequency analyzer, etc. ) Can measure the size of the vibration, through frequency points cannot deduce the abnormal situation. Due to the measured values of bearing or sensor installation position and different using conditions, thus requiring prior to each machine is analyzed by the measured value of the determined after judgment standard. As bearing even with slight stripping damage, also an exception and irregular, and therefore with the sound of the measuring device can distinguish, USES the sound device, bearing in operation to check the size of the rolling sound and quality, have the effect of prevention in advance. No matter how high quality KOYO bearing, if use undeserved, also hard to get the desired performance. About the use of the rolling bearing considerations are as follows: 1, keep the KOYO bearing and bearing around even small dust cleaning, will also bring bad influence to the bearings. So, keep the surrounding clean, dust from invading bearing. 2, use must be careful in use for 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, use the appropriate operating tools must use the right tools, avoid to existing tools instead. 4, pay attention to the bearing corrosion, timely change when bearing operation, sweat will become the cause of rust. Pay attention to the operation with clean hands, it is better to try to bring gloves. Finally, for as long as possible in good condition to maintain the performance of the rolling bearing was required to 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, KOYO bearing the rotation of the sound, vibration, temperature, the state of the lubricants and so on.
