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 ...
