Embodiment Construction

[0036] The bearing supporting device and installation method for a wind power generating set according to an embodiment of the present invention will be described in detail below with reference to the accompanying drawings.

[0037] The wind power generator of the present invention adopts a direct drive type wind power generator. The installation method of the wind power generating set is especially suitable for the hoisting of the direct drive wind power generator.

[0038] Such as figure 2 As shown, according to the embodiment of the present invention, the wind power generating set mainly includes four parts: the impeller, the generator, the main frame 11 of the nacelle and the tower 13 .

[0039] Among them, the tower tube 13 mainly plays a bearing role and is used to carry other components. The main frame 11 of the nacelle is arranged on the tower 13 and is used for installing generators, control components and other components. The yaw bearing 12 is arranged on the ma...

Abstract

The invention provides a bearing supporting device used for a wind generating set, an installing method and the wind generating set. The wind generating set comprises an impeller and a generator. A main bearing pedestal of the generator is sleeved with a hub of the impeller. The bearing supporting device used for the wind generating set comprises at least one locking connecting part, and the locking connecting parts are provided with locking wedges arranged between the main bearing pedestal and the hub. The lifting difficulty can be lowered through the bearing supporting device used for the wind generating set.

Description

technical field [0001] The invention relates to the field of wind power generators, in particular to a bearing support device for a wind power generator set, an installation method, and a wind power generator set. Background technique [0002] Such as figure 1 As shown, a direct-drive wind turbine usually consists of an impeller, a generator, a main frame of the nacelle, and a tower. Among them, the generator is arranged on the main frame of the nacelle, and the impeller is arranged on the main shaft through the main bearing, and the main shaft is connected with the generator. The impeller usually consists of a hub 3', a plurality of blades arranged on the hub 3', a corresponding pitch system, a shroud, and the like. During assembly, the hub 3' of the impeller is connected with the bearing seat 7' of the main shaft. [0003] When the wind turbine is working, the impeller is driven by the wind to rotate, which in turn drives the rotor of the generator to rotate, realizing ...
