The determination of whether the bearing can be used; mainly to consider the degree of bearing damage, mechanical function, importance, working conditions, and the time to the next inspection. If there are the following shortcomings, it can no longer be used; it is necessary to replace the new bearing. There is a crack or a gap in any of the outer ring, the roll body, and the support frame.
1. There is crack on any one of the ferrule and the rolling body.
2. There are significant card injuries on the rolling track, ribs and roll.
3, adhere to the frame wear is significant, perhaps the rivet is significantly relaxed.
4. There is rust on the raceway surface and the rolling body; there is injury.
5. There are severe indentations and marks on the raceway surface and the rolling body.
6. There is significant creep in the inner diameter surface of the inner ring or the outer diameter surface of the outer ring.
7, the color change due to heat is significant.
8. Bearings sealed with grease; damage to seals or dust caps is significant.
The protection of the bearing is to adhere to the original function of the bearing in an outstanding condition for as long as possible; it must be protected, repaired, and prevented from being in the forefront; ensure the reliability of work; improve productivity, economy, protect the best corresponding mechanical working conditions The operation specification; timed. The content includes supervision of working conditions, compensation or replacement of lubricants, and timely disassembly. As an overhaul in the work; there are bearing rotation, oscillation, temperature, lubricant condition, etc.
Matters needing attention in bearing operation:
Rolling bearings are fine parts; their use must be carried out in a stable manner. No matter how high-performance bearings are used, if they are not used properly, they will not achieve the expected high functions. The application of the bearings is as follows.
(1), adhere to the bearing and its surrounding health.
Even small dust that cannot be seen by the eyes will have a bad influence on the bearings. Therefore, it is necessary to adhere to the surrounding sanitation; so that the dust does not invade the bearings.
(2), use it cautiously.
In the application, the bearing is subjected to severe impact; there will be scars and indentations; it will be the cause of the incident. Under severe conditions; cracks and cracks will occur; so it is necessary to pay attention.
(3) Use appropriate operational things.
Prevent the replacement of existing things; it is necessary to use the right things.
(4), should pay attention to the corrosion of the bearing.
When operating the bearing; the sweat on the hand will become the cause of rust. Pay attention to the operation with clean hands; the best possible to wear gloves.
Clearance of bearing inspection bearing: When disassembling the lower bearing for inspection; first record the appearance of the bearing; acknowledge the residual amount of lubricant; after sampling and checking the lubricant; wash the bearing. As a scavenger; generally use gasoline, fire oil. The removal of the bearing; the coarse removal and fine removal; do not leave in the container; first put the metal mesh bottom; so that the bearing does not directly touch the container of the dirt. When the coarse removal; if the bearing is rotated with dirt; Will damage the rolling surface of the bearing; should pay attention to. In the coarse oil removal; use the brush to remove the grease, adhesive; after cleaning; after the fine wash; fine wash; is to rotate the bearing while cleaning the oil; Careful removal. Others; cleaning oil should always adhere to hygiene. Bearing repair and discrimination: in order to determine whether the opened bearing can be used; to check after the bearing is clean. View the raceway surface, roll surface, cooperation The condition of the surface, the wear condition of the support frame, the addition of the bearing clearance and the damage with irrelevant scale accuracy; the abnormal. Non-detached small ball bearing; the inner ring is supported by the water with one hand Rotating outer ring recognizes whether it can flow. Tapered roller bearings and other off-the-way bearings; can view the rolling surface of the rolling body and outer ring. Large bearings cannot be rotated by hand; pay attention to view rolling body, raceway surface, and stick The appearance of the frame, the ribbing surface, etc.; the higher the importance of the bearing, the more stable it is necessary to view.
