FAG outer spherical bearing, also called insert bearings, provide a simple and economical means of mounting shafts to conveyor frames, support structures, and other applications where a high degree of misalignment is present.
FAG outer spherical bearing is the main vibration source that is difficult to control. Because the vibrating screen depends on a large excitation force to maintain the limit speed and friction coefficient of the working bearing, the radial force on the outer spherical bearing is large. During the working process of the vibrating screen, a large excitation force will cause the elastic vibration of the bearing system.
If the lubrication is poor, there will be large friction, so that the bearing temperature rise is too high, the thermal expansion is too large, and the radial clearance is significantly reduced, which intensifies the friction and further improves the temperature rise.Simple treatment of problems affecting the service life of IKO thin wall bearing
The locking methods of bearings are generally divided into two types:Simple treatment of problems affecting the service life of IKO thin wall bearing
1. Bearing attached with screws
Just lock the fastening screw on the extension part of the inner ring to fix the bearing seat, and lock it with a hexagonal wrench. Please select a hex wrench of appropriate size.Simple treatment of problems affecting the service life of IKO thin wall bearing
2. Bearing with locking sleeve
The fair locking sleeve has a recess, which is fair to the vibration and temperature of the outer spherical bearing. The recess is fair to its inner hole, and there is also a part of the inner ring of the bearing seat.
First position the fair sleeve on the inner ring, rotate the fair bearing sleeve quickly towards the rotation direction of the shaft until it is clamped, and lock the screw with a hexagonal wrench.Simple treatment of problems affecting the service life of IKO thin wall bearing.Methods to avoid vibration during operation of fag outer spherical bearing
The vibration system composed of bearing and eccentric system can be regarded as a single degree of freedom system. Fag bearing driving shaft and driven shaft system have a certain resonance frequency.
If a certain excitation frequency is close to the resonance frequency, resonance will occur. In addition, due to the centrifugal inertia force of eccentricity, bending vibration will occur, which is the material factor affecting the service life of bearing. If the speed is close to the critical value, bending resonance will occur.Simple treatment of problems affecting the service life of IKO thin wall bearing
It can be inferred from the measurement of the vibration and crack of the bearing that the vibration and crack of the bearing are not sensitive to the specific vibration and crack of the bearing. Therefore, the vibration analyzer can be used to measure the vibration and crack of the bearing.
Because the measured values are different due to the service conditions of the bearing or the installation position of the sensor, it is necessary to analyze and compare the measured values of each machine in advance to determine the judgment standard.Simple treatment of problems affecting the service life of IKO thin wall bearing.Methods to avoid vibration during operation of fag outer spherical bearing
Even if the bearing has slight peeling and other damage, it will emit abnormal sound and irregular sound. Therefore, the sound detector can be used to distinguish. The sound detector is used to check the size and sound quality of the fag sound of the running bearing, which plays the role of prevention in advance.Simple treatment of problems affecting the service life of IKO thin wall bearing
Methods to avoid vibration during operation of fag outer spherical bearing
1. Pay attention to keep the outer spherical bearing and its surroundings clean
Even small dust will have a bad impact on the bearing. Therefore, keep the surrounding clean so that the dust will not invade the bearing.Methods to avoid vibration during operation of fag outer spherical bearing
2. Use with care
Strong impact on the bearing during use will produce scars and indentation, which will become the cause of the accident. In serious cases, it will crack and fracture, so we must pay attention to it.Methods to avoid vibration during operation of fag outer spherical bearing
3. Use appropriate operating tools
Appropriate tools must be used to avoid replacing existing tools.
4. Pay attention to the corrosion of the bearing and replace it in time
When operating the bearing, the sweat on the hand will become the cause of rust. Pay attention to operate with clean hands and try to wear gloves.Methods to avoid vibration during operation of fag outer spherical bearing
After, in order to maintain the original performance of fag bearing in good condition for as long as possible, it is necessary to maintain and repair in order to prevent accidents, ensure the reliability of operation and improve productivity and economy. Maintain the operation standard of corresponding mechanical operation conditions and carry out it regularly.
The contents include monitoring the operation status, replenishing or changing the lubricant, and regular disassembly inspection. As maintenance items in operation, there are rotating sound, vibration, temperature, lubricant state of outer spherical bearing, etc.Simple treatment of problems affecting the service life of IKO thin wall bearing.Methods to avoid vibration during operation of fag outer spherical bearing
