Motor shaft crack, fracture or bending generally have the following conditions, it is recommended to check frequently, so as not to cause great consequences.
              1.If the transverse crack of the shaft does not exceed 15% of the journal and the longitudinal crack does not exceed 10% of the circumference, it can be repaired by repair welding method, and it can still be used after leveling.
              2.If the shaft crack reaches a certain degree or the shaft is broken, which affects the safe operation of the motor, a new shaft should be replaced.
              3.If the shaft bending will make the shaft bear the applied pressure, serious bending will cause the phenomenon of bore sweeping, even make the motor rotor can not rotate in the T-shaped cavity. The treatment is to clamp the shaft on the lathe and check with a dial indicator; if the shaft is bent
              It is not more than 0.1mm per meter and the bending degree of the whole length is not more than 0.2mm, which generally does not need to be corrected; if the bending degree is large, the method of pressure pressure shall be adopted for correction, or after the surface of the bending part is evenly overlaid,
              In the lathe will be processed to the original size; if the bending is large, should replace the shaft.
