Maintenance methods and procedures for bearing wear

wallpapers Environment 2020-10-27

Wear of the bearings can be repaired in this way. The solution is: need to re-study the use conditions or re-select the bearing, observe the clearance and check the machining precision between the shaft and the bearing bar, check the design around the bearing, study and check the installation method and the lubricant and lubrication method.

Bearing bit wear can be repaired in this way/step

1. Do the preparatory work, that is, the disassembly of equipment, to ensure sufficient construction space and safe working environment;

2. Preliminary cleaning of the shaft surface, that is, wipe off the oil stains on the bearing position and the positioning surface surface, and remove high spots, burrs, rust layers, etc., use 99.7% absolute ethanol to clean the bearing position surface to ensure that there is no dirt. Dry

3. Wipe the inner and outer surfaces of the mold clean, wipe a thin layer of SD7000 release agent on the inner surface of the mold, the discharge groove, the bolts, the bolt holes, the positioning pins, and the positioning pin holes. The thinner the better, and dry it for later use;

4. Strictly follow the proportion of volume ratio 2:1 to blend the material SD7101H, and the blend is fully and without color difference, and the blended material is quickly applied to the surface of the bearing position;

5. Quickly install the mold in place, tighten the bolts and install the positioning pins. Pay attention to the mold during the installation of the mold to avoid axial movement of the mold. At the same time, use a rubber hammer to beat the mold in the circumferential direction during the process of tightening the mold to make the material distribution more uniform and avoid the deformation of the mold;

6. Material curing: when the ambient temperature is 24℃, it is recommended to remove the mold for no less than 4 hours; when the ambient temperature is below 24℃, it is recommended to use an iodine tungsten lamp to heat for not less than 3 hours;

7. Be careful when removing the mold to avoid material damage or falling off during the disassembly process. After the mold is disassembled, use a saw blade or a cutting blade to remove the excess material extruded from the discharge trough (no knocking or hand breaking is prohibited). Polish here below the overall surface;

8. Assembling parts: When assembling parts, it is recommended to apply a thin layer of release agent on the mating surface of the part, and apply a thin layer of material on the surface of the bearing position, and install it in strict accordance with the assembly process.

It is of great significance to study the formation and causes of rolling bearing damage. On the one hand, it can improve the use method, use the bearing correctly, and give full play to the performance of the bearing. On the other hand, it will help to develop new products with better performance. In addition to describing the precautions, installation methods, and operation monitoring of rolling bearings, this article also focuses on the forms and causes of bearing damage and the countermeasures to be taken.

The life of the bearing has a certain number of years. If we use it properly and pay attention to the above use matters normally, the bearing will fully play its role. Generally, the brand bearings of regular manufacturers provide three guarantees. If it is a quality problem, you can go to the corresponding store to exchange. Generally specialty stores have this service.
