Regular inspection of IKO bearing is a very important work for maintaining the fully loaded cylindrical roller bearing in good condition, which can also reflect the problems found. Matters needing attention and relevant knowledge about bearing in use.
First of all, we want to emphasize that it is very important to keep IKO bearings lubricated and clean. Therefore, before we inspect the fully loaded cylindrical roller bearing, we should first clean the surface of the bearing, and then disassemble the parts around the bearing.
It should be noted that the oil seal is a very fragile part, so you need to be extra careful during inspection and disassembly. Do not apply excessive force to avoid damage to the parts. Then carefully check the oil seal of the bearing and its surrounding parts.
If there are bad symptoms, be sure to replace it. The bad oil seal will lead to the damage of the bearing and the abnormal cloud shape of the bearing, resulting in the shutdown of the equipment.
Secondly, we also need to check the lubricant of IKO bearing. Lubrication is very important, not for full cylindrical roller bearings, but also for all bearings. However, please note that the bearing should not add too much grease.
IKO bearing cleaning: gasoline and kerosene are used as common cleaning agents. When disassembling the lower bearing for maintenance, first record the appearance of the fully loaded cylindrical roller bearing, confirm the residual amount of lubricant, take samples of the lubricant used for inspection, and then wash the bearing.
Cleaning can be divided into coarse cleaning and fine cleaning. Put them in the container respectively, and put the metal mesh cushion on the bottom first, so that the bearing does not directly contact the dirt of the container.
1. After rough cleaning, remove the grease and adhesion with a brush. After it is roughly clean, turn to fine cleaning. If the full cylindrical roller bearing rotates with dirt, it will damage the rolling surface of the bearing, which should be paid attention to.
2. Fine cleaning is to carefully clean the fully loaded cylindrical roller bearing while rotating in the cleaning oil. In addition, the cleaning oil should always be kept clean.
Maintenance and judgment of IKO bearing: in order to judge whether the disassembled bearing can be used, it shall be checked after the full cylindrical roller bearing is cleaned.
The fatigue failure of Koyo imported bearing is a surface form of failure, which is mainly manifested in the initiation, propagation and fracture process of fatigue crack, and the long-term impact of load failure Cylindrical Roller Bearing under alternating conditions. Cracks are in two ways:
1. On the surface, this is the effect of external load caused by the Cylindrical Roller Bearing plastic deformation on the working surface and the periodic change of contact stress on the strain hardened surface during the rolling contact process of
Koyo imported bearing, and finally the formation of surface cracks between small cracks from the developing inner surface, due to the lubricant and opening force on the working surface, Crack down on the wall and force the crack to move forward;
2. From the surface layer, under repeated pressure, the contact of the surface will initially produce cracks at a certain depth at the place where the surface is exposed,
and from the angle along the surface direction to a certain depth, from behind the surface of the contact surface, and beyond the surface, and finally form corrosion stripping, leaving a horse pit.
From the surface of Koyo imported bearing, or from the cracks in the surface layer, these two objectives (carburization, quenching and other surface heat treatment of parts. If there are uneven hardness, microstructure, non-uniform internal stress and other disadvantages,
the contact stress is generally affected by the opposite underground cracks. If the surface quality of parts is poor, there is a defect (oxidation, decarburization), Poor friction or lubrication, cracks from the surface.
The methods to control the sound of raceway are: select the low-noise Koyo imported bearing, that is, the bearing with small waviness, and carefully select the service conditions. Raceway noise often affects the noise of the whole machinery. Reducing raceway noise can reduce the noise of the whole machinery.
The bearing has long service life and can be used correctly If the damage occurs prematurely, it is likely to be caused by wrong type selection, improper use or poor lubrication.
Therefore, when installing Koyo imported bearings, we need to record the type of machine, installation position, service conditions and surrounding cooperation. By studying and summarizing the types of bearing damage and the service environment when problems occur, so as to avoid similar situations from happening again.
