Clearing support tool of rotor of MW (megawatt)-level permanent magnetic direct drive wind driven generator

Abstract

The invention relates to a clearing support tool of a rotor of an MW (megawatt)-level permanent magnetic direct drive wind driven generator. The clearing support tool comprises a support H steel, an upper support end plate welded on the top of the support H steel, rib plates welded on two flanks of the support H steel, and a lower support end plate welded on the bottoms of the support H steel and the rib plates, wherein a protection end plate is arranged on the upper support end plate; the protection end plate is fixedly connected with the upper support end plate by virtue of a fastener; and lower support square pipes are welded beneath the lower support end plates. According to the clearing support tool of the rotor of the MW-level permanent magnetic direct drive wind driven generator, the support stability of the rotor can be realized by adopting three or more than three clearing support tools, and the cylindricity quality of the rotor is improved. By utilizing the clearing support tool, the clearing work of the inner wall of the rotor is safely, easily, conveniently and fast completed, the clearing efficiency is high, and the production efficiency is improved.

Description

technical field [0001] The invention relates to MW level generator assembly, in particular to a MW level permanent magnet direct drive wind power generator rotor cleaning and supporting tool. Background technique [0002] MW (full name in English is megawatt, that is, power unit: megawatt) permanent magnet direct drive wind turbine rotor needs to clean the surface of the inner wall of the rotor after pushing the magnetic steel, vacuum coating and magnetic pole protection. Surface clean the inside of the rotor again. The rotor of MW-level permanent magnet direct drive generator will have cracked magnetic steel particles adsorbed on the rotor surface during the process of pushing the magnetic steel. After the rotor magnetic pole surface is vacuum coated and painted with conformal paint, it is easy to leave release cloth, colloid, and paint. These will form bumps on the inner wall of the rotor to varying degrees, resulting in hidden dangers to the quality of the rotor. If the...

If these are not removed in time during the stator and rotor assembly process, it will easily cause abnormal noise during the operation of the unit, scratch the surface of the stator, damage the stator insulator, and seriously cause breakdown of the stator

[0003] Although the MW-level permanent magnet direct-drive wind turbine rotor cleans the inner wall of the rotor after pushing the magnetic steel and magnetic pole protection, considering the drop and adsorption of foreign objects during the later operation and the limitation of the height of the rotor in the early stage, it is necessary to design a special cleaning support protective tooling
