Abstract

The invention discloses an integral assembly method for rotor magnetic poles of a wind driven generator. The assembly method comprises the following steps: 1, hoisting a rotor support to a rotor supporting table; 2, adjusting the height of a mounting platform; 3, placing a magnetic pole box on a track, controlling a propelling air cylinder to operate and push the magnetic pole box forwards along the track until the magnetic pole boxes abut against a baffle, then placing a next magnetic pole box on the track, controlling the propelling air cylinder to push the magnetic pole box forward along the track until the magnetic pole box abut against the previous magnetic pole box, and pushing other magnetic pole boxes of the magnetic pole one by one according to the method; 4, fastening all the magnetic pole boxes on the magnetic pole assembly tool are together through bolts to form a magnetic pole; and 5, detaching the baffle, and controlling a propelling air cylinder to push the magnetic pole into the rotor support along the track. According to the invention, the product reliability is improved, the labor intensity is reduced, the potential safety hazard is eliminated, and the product quality and the production efficiency are improved.

Description

technical field [0001] The invention relates to the technical field of wind power generators, in particular to a method for integrally assembling a rotor magnetic pole of a wind power generator. Background technique [0002] At present, when assembling the rotor poles of the megawatt-level medium-speed permanent magnet wind turbines, the pole boxes need to be assembled to the rotor bracket one by one, which is inefficient, and the pole boxes of a single pole are often offset, and the rotor surface is uneven, which will The gap between the stator and rotor of the generator is uneven, which affects the power generation efficiency of the generator and causes quality problems and potential safety hazards. Contents of the invention [0003] Aiming at the deficiencies in the prior art, the present invention provides a method for integrally assembling the magnetic poles of the rotor of the wind power generator to solve the problems of the prior art. [0004] In order to solve th...
