Before we inspect the Koyo bearing, we should first clean the surface of the Koyo bearing, and then disassemble the parts around the Koyo bearing. 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 Koyo 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 Koyo bearing, make the cloud shape of Koyo bearing abnormal and cause the shutdown of the equipment. So what should Koyo bearings check?
The inspection method of Koyo bearing lubricant is as follows:
Rub with a little lubricant between your fingers. If there are pollutants, you can feel them; Or apply a thin layer of lubricant on the back of the hand, and then conduct light sealing inspection.
After draining the old engine oil, if possible, fill the Koyo bearing with fresh engine oil and let the machine rotate at low speed for a few minutes. Make the oil collect residual pollutants as much as possible, and then drain the oil.
For Koyo bearings lubricated with grease, when changing the grease, the arbor used should avoid any part of the Koyo bearing with cotton joint angle. Because these residual fibers may wedge between rolling parts and cause damage, especially in the application of small Koyo bearings.
never expose the Koyo bearing to pollutants or moisture. If the work is interrupted, the machine shall be covered with oil paper, plastic sheet or similar materials.
If it is possible to clean the naked Koyo bearing without disassembly, clean it with a brush coated with petroleum solvent, and then wipe it dry with a piece of lint free cloth or blow it dry with compressed air.
Do not clean the Keyo bearing with encrypted cover or dust-proof; Just wipe the outer surface. If the Koyo bearing is damaged, it needs to be replaced. Replacing Koyo bearings during regular shutdown and maintenance is much more economical than the loss of sudden shutdown due to array bearing damage.
When changing grease, relevant connecting parts must be Lubricant disassembled. When lubricating with oil, there is no such trouble.
When the fag bearing in the reduction gearbox is lubricated with lubricating oil, it is very Lubricant suitable, because the oil can simultaneously lubricate the gear and fag bearing in a splash way.
In fag bearings, the lubricating grease is gradually contaminated by the products of product wear, Lubricant abrasives, products penetrating through the sealing device from the outside and aging itself.
If it is not replaced in time, it will cause accelerated wear of fag Lubricant bearings. When liquid lubricant is applied, it can be filtered to ensure its normal operation. Advantages of grease lubrication for rolling fag bearings:
When selecting lubricating grease, it is necessary to select the lubricating grease suitable for the service conditions (temperature, speed, load and environment, etc.), which are related to the basic characteristics of lubricating grease, and the basic characteristics of lubricating grease depend on the type of thickener and base oil.
