Maintenance method of bearing wear

wallpapers Products 2020-12-11

As we all know, bearings are very important in our lives. 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.


The bit wear of bearings can be repaired in the following ways

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, to wipe off the oil stains on the bearing position and the positioning surface, and remove high spots, burrs, rust layers, etc., use 99.7% absolute ethanol to clean the bearing position surface to ensure no dirt.


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


4. The material SD7101H is blended in strict accordance with the ratio of volume to 2:1, and the blending is sufficient without colour difference, and the blended material is quickly applied to the surface of the bearing position;


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


6. Material curing: when the ambient temperature is 24°C, it is recommended to remove the mould for no less than 4 hours; when the ambient temperature is below 24°C, it is recommended to use an iodine tungsten lamp to heat for no less than 3 hours;


7. Be careful when dismantling the mould to avoid material damage or falling off during the disassembly process. After the mould is disassembled, use a saw blade or a cutting blade to remove the excess material extruded from the discharge trough, and at the same time, polish it 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 parts in advance, and apply a thin layer of material on the surface of the bearing position, and install it in strict accordance with the assembly process.
