The invention provides a vertical suspended hydro-generator thrust head fast-disassembling method which comprises the following steps of S1, lifting a special thrust head disassembling tool to the upper part of a top shaft of an electric generator, and enabling screw holes in the special thrust head disassembling tool to align at screw holes in a thrust head; S2, symmetrically selecting four holeswithout internal threads in the special thrust head disassembling tool, and enabling processed special lifting screw rods to penetrate through the special thrust head disassembling tool and screw into the thrust head screw holes; and S3, sequentially sleeving four hollow type single-action hydraulic jacks to the outer sides of the fixed four special lifting screw rods. The vertical suspended hydro-generator thrust head fast-disassembling method provided by the invention has the advantages of reasonable design, high disassembling efficiency, and capability on preventing the contact surface ofthe thrust head and the top shaft of the electric generator from being dmaged.
Description
technical field [0001] The invention relates to the technical field of maintenance of a vertical suspension type hydro-generator, in particular to a rapid disassembly method for a thrust head of a vertical suspension type hydro-generator. Background technique [0002] For large and medium-sized vertical suspended hydro-generator units, the top of the main shaft is equipped with a thrust head, which forms a thrust bearing together with thrust tiles, mirror plates and other components. Keys and snap rings are used to transmit force between the thrust head and the main shaft. The thrust head The center of rotation is fixed by interference fit between the inner hole and the main shaft. When the unit is running, the thrust head plays the role of bearing the weight of the rotating part of the unit and the axial water thrust. It is a part with heavy force, complexity and high precision requirements. Therefore, the thrust head should have sufficient strength, rigidity and certain im...
