How to operate the spray repair of the bearing chamber of the motor end cover

The motor end cover is a back cover installed behind the casing of the motor, etc., and is often ignored by equipment managers. However, when the bearing chamber of the motor end cover is worn, if it is not repaired in time, it will cause damage to the operation of the entire motor equipment. Influence.

Let's first analyze the reasons for the wear of the bearing chamber of the motor end cover:

1. When the motor is running, the vibration of the bearing increases, and the matching between the motor end cover and the inner ring of the bearing is out of tolerance.

2. The motor assembly process is poor, and the rotor, bearing and end cover of the motor are not concentric, resulting in an increase in the amount of vibration when the motor is running.

3. The motor assembly is unreasonable, and the outer ring runs during operation, resulting in the bearing chamber being out of tolerance.

4. The insufficient amount of motor grease will cause the equipment to run out of oil and the bearing to heat up, causing the relative movement of the inner and outer rings of the bearing to increase the fitting clearance.

5. The motor vibrates violently during operation, resulting in damage to the bearing chamber.

The bearing chamber of the motor end cover of a certain enterprise has been worn out. At present, the Soleil carbon nano-polymer material technology can be quickly repaired. It only needs to smear and repair the worn parts. Since the material has excellent machinability, it can meet the processing requirements of turning, milling, planing and grinding, and considering the actual situation of the enterprise site, we decided to use the machining repair process to repair it. Then the specific motor end cover bearing chamber is sprayed How does the repair work?

(1) Degrease the surface of the worn part with a tool.

(2) The surface is pre-carved for rough treatment.

(3) Harmonized carbon nanopolymer material SD7101H.

(4) Coating the reconciled carbon nanopolymer material.

(5) After the material is cured, it is machined according to the matching size.

The comprehensive mechanical properties of this material are better than those of metal, and it has excellent "concession", and does not have the characteristics of metal fatigue wear and plastic deformation, so there will be no fatigue wear and fracture during long-term use, so the long-term operation of the equipment is guaranteed. During the process, there will be no gap due to fatigue wear, which ensures the use effect of the repaired equipment.
