“IKO high temperature bearing” are specially designed bearing units that can operate reliably at high temperatures without experiencing premature failure, thanks to their advanced material selection, heat treatment, and lubrication technologies.
Fault Maintenance Method of Iko High Temperature Bearing
IKO High temperature bearing show strong regularity and good repeatability in their use. When the normal high-quality bearing is put into use, the vibration and noise are relatively small, but the spectrum is scattered and the amplitude is small, which may be caused by some defects in the manufacturing process, such as surface burrs.
After moving for a period of time, the vibration and noise maintain a certain level, and the spectrum is very single, with only one or two times the frequency. The frequency spectrum above three times of power frequency rarely appears, and the state of IKO bearing is very stable and enters the stable working period.
After continued operation and Fault Maintenance Method entering the later stage of use, the vibration and noise of the bearing begin to increase, and sometimes abnormal sound occurs, but the change of vibration increase is slow.
At this time, the kurtosis value of the bearing begins to suddenly reach a certain value. We believe that the bearing shows initial failure at this time.
At this time, it is required to closely monitor the high-temperature Fault Maintenance Method bearing and pay close attention to its changes. Since then, the bearing kurtosis value began to decline rapidly and close to the normal value,
while the vibration and noise began to increase significantly, and the increase amplitude began to accelerate. When the vibration exceeded the vibration standard (such as ISO2372 standard), the Fault Maintenance Method bearing kurtosis value also began to increase rapidly.
When both the vibration standard and the kurtosis value also exceeded the normal value (kurtosis relative standard can be used), We believe that IKO bearing has entered the late fault production, so it is Fault Maintenance Method necessary to overhaul the equipment and replace the bearing in time.
Iko High Temperature Bearing characteristics of late failure
The time from serious failure Fault Maintenance Method (generally bearing damage, such as shaft holding, burn, sand frame spallation, raceway, bead wear, etc.) is mostly less than one week. The larger the equipment capacity, the faster the speed, and the shorter the interval.
Therefore, in the actual IKO bearing fault diagnosis, once the late fault characteristics are found, the Fault Maintenance Method bearing fault should be determined and the maintenance should be arranged as soon as possible.
Use factors mainly refer to whether the installation, adjustment, use and maintenance, maintenance and repair meet the technical requirements. Check and adjust the vibration and noise of the bearing during installation and maintenance according to the technical requirements of IKO,and immediately find out the cause of the abnormal vibration and maintenance of the bearing, and restore it to normal operation according to the technical requirements of Iko High Temperature Bearing.
First of all, the spindle bearing in the spindle shall be fully lubricated during operation, and the lubricating oil shall be added regularly Fault Maintenance Method according to the actual use condition, and the oil shall not be cut off for a long time.
Therefore, users and enterprises should choose better and more appropriate spindle lubricating oil. The new special spindle oil can significantly improve the lubrication performance, prolong the oil change cycle, prolong the service life of spindle and IKO bearing, and also has good anti rust and anti-corrosion properties.
Secondly, the bearing with reinforced nylon cage shall be used at a temperature lower than 120 ℃, and oil boiling and cleaning are strictly prohibited.
In addition, attention should be paid to the maintenance and cleaning of the spindle to prevent damage and scratch on the roller surface. To remove the residue of high Fault Maintenance Method temperature bearing in Sweden as far as possible,it is better to wash and suck the residual oil inside the spindle foot. Attention should be paid to avoid using the dumping type to accumulate and leave cleaning waste on the bearing, resulting in problems such as noise, wear and failure of IKO bearing.
