The shaft is an important part of the motor, as a link between the motor the equipment electromechanical energy conversion, supporting the rotating parts, transferring torque determining the relative position of the rotating parts to the stator. Therefore, the motor shaft must have reliable strength stiffness to ensure the realization of pre-set design functions. Because the motor is running constantly, the motor shaft will wear out, the motor manufacturer will teach you how to repair it.

1. According to the situation of wear parts processing unilateral bilateral positioning split tooling;

2. Surface treatment: First use the acetylene gun to bake the grease that penetrates into the surface of the worn part, the grease is carbonized. Power tools then paint the repaired area metallic. Then wash thoroughly with anhydrous ethanol to ensure that the surface is clean dry;

3. Wipe the inner surface of the tool with anhydrous ethanol, then brush with Sore SD7000 release agent to avoid unnecessary bonding;

4. Mix Solay carbon nanopolymer materials in strict proportion, stir repeatedly until the color is uniform consistent, without color difference. Then apply the material to the surface of the repair site on the surface of the repair site;

5. Material curing;

6. Disassemble the tooling check the repair size;

7. When installing the parts on the shaft, be sure to use hot assembly in order to avoid hammering.

Basic requirements of motor shaft:

1. Be intense. That is, under normal load specified special circumstances, any part of the shaft can produce residual deformation damage.

2. Have sufficient stiffness. That is, the deflection of the rotating shaft must be within the allowable range.

3. There should be sufficient difference between the critical speed the working speed to avoid resonance.
