IKO plane bearing fault maintenance precautions

Plane bearing fault characteristics show severe faults no more than a week old, with larger capacity, faster speed, and shorter time intervals. Therefore, the actual bearing fault diagnosis, once the fault is discovered, its advanced function should decisively determine the IKO bearing fault and repair it as soon as possible.
     1. Selection and control of shaft and bearing chamber tolerance: After the bearing is pressed into the plane bearing, it should be flexible and unobstructed. If the obvious rotation is not flexible, it means that the size of the shaft is too large and the tolerance is lowered. If the IKO bearing is pressed into the shaft and turned by hand, there is a clear "sand" feeling, which may be that the tolerance of the shaft is too large or the roundness of the shaft is not good. Therefore, it is necessary to control the roundness when controlling the tolerance of the shaft and the bearing chamber. At present, many domestic manufacturers only control the tolerance and do not control the roundness.
    2, the assembly of the bearing: Because the bearing is a high-precision product, such as improper assembly can easily damage the bearing channel, resulting in bearing damage. IKO bearings should have a special mold when assembling, can not be beaten at will, only a small circle of force when pressing the shaft, only a large circle when pressing the large circle. Air pressure or hydraulic pressure is required for assembly. When the press-fit is performed, the upper and lower molds are to be horizontal. If the tilting causes the flat bearing channel to be damaged due to the force, the bearing will be audible.
    3. Prevention of assembly of foreign objects: When the bearing is mounted on the rotor to make dynamic balance, it is easy to enter the iron filings generated during dynamic balancing into the bearing. Therefore, it is better to balance the load before loading the bearing. Some manufacturers have some oil or grease to lubricate the bearing chamber during assembly. However, it is often difficult for the operator to control the amount. If the oil or grease accumulates in the bearing chamber, the IKO bearing rotates. It is easy to enter the interior of the planar bearing along the shaft. It is best not to apply oil or grease to the bearing chamber. If it is not painted, it must be controlled not to accumulate in the bearing chamber.
     4, the prevention of paint rust: paint rust is characterized by multiple seals in the motor, the motor sounds very good when assembled, but after putting some time in the warehouse, the motor noise is very large, the bearing is removed Severe rust. In the past, many manufacturers thought that it was a bearing problem. After our constant publicity, the motor factory has now realized that it is mainly a problem of insulating varnish. This problem is mainly caused by the fact that the acidic substance volatilized by the insulating paint forms a corrosive substance under a certain temperature and humidity, and the IKO bearing is damaged after the plane IKO bearing channel is corroded. The problem can only be achieved by selecting a good insulating varnish and venting it after drying for a while.
What we should cause is the performance of the bearing components in this flaw and other countries' vigilance, the failure is often very fast and very sudden. It is considered to be an example of measuring the rotor shaft end after two hours.
In the diagnosis of these counterfeit bearing faults, we should focus on high-quality planar bearings, which are usually in the time domain spectrum and vibration conditions of the device. This kind of event is normal in the abnormal spectrum accumulation, so as to timely determine when IKO bearing faults and avoid equipment accidents.

The importance of IKO forklift bearing clearance and clearance lubrication

As the bearing rotates, as the IKO bearing rotates faster, the temperature rise due to the internal frictional heat of the bearing increases. The rotational speed limit is a speed allowable value that can be experienced in sintering, overheating, and continuous operation. Accordingly, the limit speed of various bearings varies depending on the bearing structure, size, cage structure, material, bearing load, lubrication method, and cooling conditions around the bearing.
    The clearance of the forklift bearing refers to the amount of movement of the bearing when it is not attached to the shaft or the bearing housing, and the one of the inner ring or the outer ring is fixed, and then the unfixed one moves in the radial or axial direction. According to the direction of movement, it can be divided into radial clearance and axial clearance.
The size of the play during operation has an effect on the rolling fatigue life, temperature rise, noise, vibration and other properties of the IKO bearing. When measuring the clearance of the bearing, in order to obtain a stable measurement value, a specified measurement load is generally applied to the bearing. Therefore, the obtained measured value is larger than the true clearance, that is, the amount of elastic deformation generated by the measuring load is increased.
    However, for the roller bearing in the bearing, since the amount of elastic deformation is small, it can be ignored. The internal clearance of the bearing before installation is generally expressed in terms of theoretical clearance.
    The lubrication of forklift bearings is to use oil film to separate the relatively moving rolling surfaces from each other, so as not to cause excessive wear due to rough contact. If the user can attach great importance to IKO bearing lubrication technology, it can guarantee stable performance and rotation accuracy during the specified working life.
    Lubrication of bearings is divided into grease lubrication and oil lubrication. The advantages of grease lubrication are simple lubrication facilities, grease leakage, and the ability of water, gas and other impurities to enter IKO bearings. Lubricated with oil under heavy load, high speed, high temperature and other working conditions.
     Grease consists of a base oil, a thickener and a filler. The viscosity of the base oil plays an important role in the lubricating properties of the grease. The composition of the thickener has an important influence on the properties of the grease, especially the temperature characteristics, water resistance and oil repellency. The filler is mainly used to enhance the resistance of the grease. Gasification, rust prevention, extreme pressure and other properties.
     Depending on the type of lubricant, the brand is different and has other properties that are not suitable for high speed rotation. Therefore, the IKO bearing rotation speed exceeds the limit rotation speed of 70% in the bearing size table, and it is necessary to select grease and lubricating oil with excellent high-speed performance.
    In the various bearing sizes of forklift trucks, the limit speeds of grease lubrication and oil lubrication are recorded for each IKO bearing. This value is the number of rotations allowed for a standard designed bearing under normal load conditions, grease lubrication, and oil lubrication operation. The value of oil lubrication is based on oil bath lubrication.
