Extend the service life of KOYO oilless bearing several matters needing attention
by:Waxing2020-11-03
In principle, all KOYO bearing before installation should be stored in their original packaging.
They need to stay clean, no moisture, relatively constant temperature environment.
Without oil bearing should stay away from dust, water and corrosive chemicals.
Shaking and vibration may never destroy KOYO bearing mechanical properties, so the vibrations must be avoided in the process of handling and storage.
Basically, all bearing must be level to save, because some of the heavier oilless bearing long upright, may be due to its own weight and deformation.
In advance (coated with grease
Or sealed)
KOYO bearing need to be especially careful, because the grease will change after long time of storage density.
So when the bearing is used for the first time, there will be a certain degree of rotation noise.
Therefore, this kind of bearing on time should be controlled according to the principle of first in first out.
(
1)
Axis right decision in the radial direction and axial direction of the location of the at the same time, inhibition of the shaft.
(
2)
To improve the bearing rigidity.
Machine tool spindle bearing with no oil, cycling differential pinion bearing.
(
3)
To prevent vibration and axial direction due to the resonance caused by the different sound.
With small motor bearings.
For centripetal bearing under combined load function, due to the number of rolling element load increase, the friction resistance increases, the amount of fever, lubrication and cooling conditions, but also increases, the force applied to keep the rack, therefore, must according to KOYO bearing type and the size of the load Angle, there can be no oil bearing limit speed multiplied by a lower coefficient of f2 to regulate them.
If selected KOYO bearing speed limit speed application requirements cannot be satisfied, can use some method of improvement skills progress, to get to meet the request.
Such as increasing oilless bearing tolerance level;
Appropriate increase clearance;
Use special materials and improved in frame structure;
Shift the lubrication method, such as oil and gas, oil mist with jet lubrication;
Improved cooling conditions, etc.
