Since water-soluble cutting fluid is used for oil-free bearings, users must make more efforts in machine tool maintenance and treatment to Iko Bearing Corrosion control erosion and even basically eliminate erosion.
In order to prevent water from eroding the metal surface, the Iko Bearing Corrosion machine tool should always be fully lubricated and the important parts of the machine tool should be coated with grease.
Oil – free bearing can have a long service life under accurate use If there is premature damage, it is likely to be caused by wrong type selection, improper use or poor lubrication.
Therefore, when installing IKO bearing, we need to record the type of machine, installation position, use premise and nearby cooperation. By studying and summarizing the types of bearing damage and the use environment when the problem occurs, so as to avoid similar situations from happening again.
Properly control the concentration of cutting fluid. When the machine tool stops working, wash the Iko Bearing Corrosion surface of the machine tool with cutting fluid, and open the shield of the machine tool to disperse the moist air in the working area of the machine tool.
In order to prevent the occurrence of electric corrosion, a layer of waterproof lubricating grease shall be applied on the metal surface. Moreover, the machine tool should be strictly grounded, and it is not enough to only ground the electrical cabinet.
In order to avoid the breeding and Iko Bearing Corrosion reproduction of bacteria, the cutting fluid should be cleaned or replaced on schedule, the chips should be removed in time, and the cutting concentrate should be diluted with soft water (pure water with low mineral content).
It is both a high-performance bearing. If it is not used properly in the process of use, it will not only fail to achieve the expected Iko Bearing Corrosion functional effect, but also easily damage IKO bearing. Everyone must have paid attention to lubrication.
1、 When using and installing, it is necessary to be careful. Strong stamping is not allowed. It is not allowed to knock the bearing vertically. It is not allowed to transfer pressure through the moving bullet body.
2、 Use proper and correct installation tools, try to use special tools, and try to avoid using cloth, short fiber and other things.
3、 Try to keep the bearing and its surrounding environment clean. Even if the invisible smile dust Iko Bearing Corrosion enters the bearing, it will increase the wear, vibration and noise of IKO bearing.
4、 To prevent the corrosion of IKO bearing, when taking the bearing directly by hand, fully wash the liquid on your hand and apply high-quality mineral oil before operation. Pay special attention to rust prevention in rainy season and summer.
Under a special operating condition, oil-free bearing can obtain a longer service life than traditional Iko Bearing Corrosion calculation, especially under light load. These special control premise is that when the moving surface (track and moving parts)
is effectively separated by a lubricating oil film and limits the possible surface damage caused by pollutants. In fact, under the ideal Iko Bearing Corrosion premise, the so-called permanent IKO bearing life is possible
High temperature bearings 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 Iko Bearing Corrosion 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 bearing and pay close attention to its changes. Since then, the bearing kurtosis value began to decline rapidly and close to the normal Iko Bearing Corrosion 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 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 necessary to overhaul the equipment and replace the bearing in time.
Swedish high-temperature bearings show the characteristics of late failure. The time from serious failure (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 Iko Bearing Corrosion 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 Iko Bearing Corrosion according to the technical requirements of IKO.
First of all, the spindle bearing in the spindle shall be fully lubricated during operation, and the lubricating oil shall be added regularly 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 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.
