Avoid FAG cause vibrations in the process of outer spherical bearing operation method

FAG 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 the outer spherical bearing of 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 spherical 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. FAG 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 outer spherical bearing vibration tester ( 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. Because bearing even slightly stripping damage, such as also emits an exception and irregular, and therefore with the sound of the measuring device can distinguish, USES the sound device, the size and quality of bearing FAG sound in operation to check, have the effect of prevention in advance. No matter how high quality outside the spherical bearing, if use undeserved, also hard to get the desired performance. The FAG bearing the use of the matters needing attention are as follows: 1, keep the outer spherical bearing and the 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 original performance, FAG bearing arrangement must be maintenance, repair, in order to prevent accident, to ensure reliability of the operation, increase 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, the rotation of the outer spherical bearing the sound, vibration, temperature, the state of the lubricants and so on.
