Embodiment Construction

[0021] The present invention will be specifically introduced below in conjunction with the accompanying drawings and specific embodiments.

[0022] Such as Figure 1 to Figure 4 As shown, a yaw pitch mechanism includes: a pitch device 10 and a yaw device 20 . The pitch control device 10 is used to adjust the windward angle of the blades of the wind generator. The yaw device 20 is used to adjust the windward direction of the nacelle of the wind power generator.

[0023] The pitch device 10 includes: a pitch motor 11 , a pitch gearbox 12 , a pitch output gear 13 and a blade bearing ring gear 14 . The pitch motor 11 is connected to the input of a pitch gearbox 12 . The pitch output gear 13 is connected to the output end of the pitch gearbox 12 . The pitch output gear 13 meshes with the blade bearing ring gear 14 .

[0024] Specifically, the pitch gearbox 12 transmits the power input by the pitch motor 11 to the pitch output gear 13 to drive the pitch output gear 13 . The pi...

Abstract

The invention discloses a yaw variable pitch mechanism. The yaw variable pitch mechanism comprises a variable pitch device for adjusting the windward angle of blades of a wind driven generator, and ayaw device for adjusting the yaw direction of a cabin of the wind driven generator; the variable pitch device comprises a variable pitch motor, a variable pitch gearbox, a variable pitch output gear and a blade bearing gear ring; the yaw device comprises a yaw motor, a yaw gearbox, a yaw output gear and a yaw gear ring; the yaw gear ring and the blade bearing gear ring are the same in module and pressure angle; and the variable pitch gearbox and the yaw gearbox are the same in structure. The yaw variable pitch mechanism further comprises a first machine seat for installing the variable pitch gearbox, and a second machine seat for installing the yaw gearbox; and a machine seat connector, used for being connected with the variable pitch gearbox, of the first machine seat and a machine seat connector, used for being connected with the yaw gearbox, of the second machine seat are the same. The yaw gearbox and the variable pitch gearbox have the universality, the development cycle is shortened, the types of the gearboxes are decreased, and the scale effect is improved.

Description

technical field [0001] The invention relates to a yaw pitch change mechanism. Background technique [0002] The yaw pitch mechanism is an important part of the wind turbine, which includes a motor, a reduction gearbox, and a toothed slewing bearing. Among them, the yaw mechanism is used to adjust the direction of the nacelle facing the wind, and the pitch mechanism is used to adjust the windward angle of the blades to improve the power generation efficiency of the fan. However, the structure of the yaw mechanism and the pitch mechanism of traditional wind turbines is very different, and each needs to be independently designed, developed, produced, tested, packaged and delivered. operating costs. Contents of the invention [0003] The invention provides a yaw and pitch change mechanism, which adopts the following technical scheme: [0004] A yaw pitch change mechanism, comprising: a pitch change device for adjusting the windward angle of the blades of the wind-driven gen...
