Embodiment Construction

[0035] The wind power generating set and its installation method according to the embodiment of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0036] like Figure 5 and Figure 6 As shown, the wind power generating set includes a tower 10 , a nacelle 20 , a generator 30 and an impeller 40 .

[0037] Specifically, the tower 10 is fixed on the ground or other foundations, and is used to support other parts.

[0038] The base 21 of the nacelle 20 is connected to the top of the tower 10 through a yaw bearing 60 . The nacelle 20 also includes components such as a yaw drive, a nacelle control cabinet, and a nacelle cover, which are used to control the wind power generating set.

[0039] The generator 30 is connected with the base 21, and it is used for converting wind energy into electrical energy to realize power generation.

[0040] The impeller 40 is connected with the generator 30 and includes an impeller shaft 41 , a...

Abstract

The invention provides a wind driven generator, a wind driven generator set and an installation method thereof. The wind driven generator comprises a stator and a rotor coating the stator, and further comprises a driving part connected with the rotor and driving the rotor to axially move. The wind driven generator can reduce the lifting difficulty.

Description

technical field [0001] The invention relates to the field of wind power generator equipment, in particular to a wind power generator, a wind power generator set and an installation method thereof. Background technique [0002] The reliability of wind turbines is an important parameter of wind turbines. As an important supporting structure of the wind turbine, the transmission chain is a key component of the mechanical design of the wind turbine. As the mainstream technical solution in the wind power market, the direct-drive wind turbine has many different transmission chain forms, such as single-point support type and two-point support type, [0003] Among them, the two-point support means that the main shaft is supported by two bearings, one of which is axially positioned, and the other axially moves. Some wind turbines arrange double bearings in the hub. Other wind turbines have dual bearings located outside the hub, such as inside the generator or inside the nacelle. ...
