Embodiment Construction

[0026] Below in conjunction with embodiment and attached Figure 2-5 It will be described in further detail, but the embodiments of the present invention are not limited thereto.

[0027] Such as figure 2 As shown, the maintenance process flow chart of the present invention, its maintenance process is: appearance inspection - removal of slip ring - motor disintegration, wherein, after the motor is disassembled, each component is subjected to separate maintenance, including: slip ring maintenance, rotor insulation treatment, rotor Screw hole inserting, end cover crack welding repair and auxiliary stator transformation, after the repair of each component, the motor assembly-insulation test is passed-out of the section.

[0028] When implementing, carry out routine visual inspection and cleaning first.

[0029]After the routine visual inspection, the slip ring is removed, and the self-made slip ring pull-out tooling is used for removal. The tooling has won the national patent ...

Abstract

The invention relates to the technical field of train motor overhauling processes, in particular to a novel traction generator overhauling process. An overhauling process includes the steps of appearance inspection, slip ring dismantling, motor disassembly, motor overhauling and motor assembly, wherein overhauling including slip ring overhauling, rotor insulation processing, rotor screw hole inserting and bushing, end cover crack repairing welding and auxiliary generator stator modification is respectively performed on all of parts after motor disassembly, and motor assembly, qualified insulation detection and section output are performed after all of parts are overhauled. The main and auxiliary generator overhauling process overcomes the problem that HXN5 main and auxiliary generators are complicated in structure, free of relevant experiences for reference and large in overhauling difficulty when being overhauled for the first time and is a special overhauling process for the HXN5 main and auxiliary generators, the blank of an HXN5 main and auxiliary generator overhauling process is filled by improving and innovating main and auxiliary generator overhauling processes, the main and auxiliary generator faults can be repaired, hidden danger can be eliminated, and the motor overhauling level can be improved.

Description

technical field [0001] The invention relates to the technical field of train motor maintenance technology, in particular to a novel traction generator maintenance technology. Background technique [0002] The main and auxiliary generators of the HXN5 locomotive are 5GMG201E1 synchronous traction generators. This is the first overhaul. Its motor structure is completely different from that of Dongfeng series main generators. The machine is coaxial, which is equivalent to 4 motors in one base, and the structure is complex. [0003] The auxiliary generator stator is in the form of an inner stator, inside the auxiliary generator rotor, it is connected and fixed with the end cover through the seam. The auxiliary generator stator has three sets of independent windings: battery winding, excitation winding, and fan winding, which respectively supply power for the battery charger, main generator excitation circuit, and cooling fan. Due to the many types of windings, the layout princ...
