Abstract
The invention relates to a motor main shaft repairing method. The method comprises the following steps that 1, a bending or breaking part of a main shaft is removed; 2, a section of a repair shaft which has the same quenched and tempered material as that of the main shaft is machined; 3, a cylindrical contained part used for being connected with the main shaft is machined on the middle position of one end of the repair shaft; 4, a round-hole-shaped containing part corresponding to the contained part is machined on the middle position of the main shaft repair end; 5, the end, provided with the contained part, of the repair shaft is machined with an angle P, and the end, provided with the containing part, of the main shaft is machined with an angle K corresponding to the angle P; 6, a seam is welded; 7, finish machining is conducted according to the original size. The motor main shaft repairing method has the advantages that rotor and main shaft disassembling is not needed for repairing of the main shaft, and therefore the phenomenon of rotor insulation harm caused by disassembling is avoided; in addition, the materials are saved, and the overall machining cycle is shortened.
Description
Technical field
