Problems causing the INA plane bearing cage to break
The factors that cause the INA plane bearing cage to break are as follows:
First: plane bearing cage abnormal load
If the installation is not in place, the inclination, the interference is too large, etc., the clearance is reduced, the friction heat is increased, the surface is softened, and the abnormal peeling occurs prematurely. As the peeling spreads, the foreign matter is peeled off into the pocket of the cage, resulting in the cage. The blockage of operation and the generation of additional loads exacerbate the wear of the cage, and the deterioration of the circulation can cause the cage to break.
Second: INA bearing creep phenomenon
The creep phenomenon refers to the sliding phenomenon of the ferrule. When the interference of the mating surface is insufficient, the load point moves in the peripheral direction due to the sliding, and the ferrule is displaced from the axis or the outer casing in the circumferential direction.
Third: bearing cage material defects
Cracks, large dissimilar metal inclusions, shrinkage cavities, air bubbles and riveting defects, nails, padding or two-half cage joint surface voids, severe riveting, etc. may cause the cage to break.
Fourth: poor bearing lubrication
The plane bearing is in a lean state, which is easy to form adhesive wear, which deteriorates the working surface condition. The tearing material generated by adhesive wear easily enters the cage, causing an abnormal load on the cage, which may cause the cage to break.
Fifth: INA bearing intrusion of hard foreign objects
The intrusion of foreign hard foreign objects exacerbates the wear of the cage and creates an abnormal additional load, which may also cause the cage to break.
When it breaks, the repair method is as follows:
Preparation: dry towel, sharp tongs, flat bearing cleaning night, INA bearing lubricant or grease.
a. Remove the C-shaped ring and the cover: Wipe off the dirt outside the bearing with a dry towel, then use a pointed plier to lift the side of the C-shaped ring and take the C-ring and the cover off.
b.INA bearing cleaning fluid: soak the bearing in the bearing cleaning fluid bought on the market, and shake it at this time, the foreign matter inside the plane bearing will be shaken out, and some supermarkets buy ultrasonic cleaning machine to remove foreign matter. helpful.
c. Drying: Take the bearing out of the cleaning solution, wipe the cleaning solution with a dry towel, and dry it in a cool place.
d. Inject the lubricant according to the trend to inject grease or oil into the bearing, cover the shroud and reattach the C-ring.
e. Detection: The INA bearing that has been assembled into the original state is rotated several times after grasping the inner ring with fingers.
