Embodiment Construction

[0010] As shown in the figure: on the top of the annular brake disc 1 is a ring-shaped slewing bearing 2 connected to each other, teeth 3 are arranged on the outer edge of the slewing bearing 2, and there is a reducer 11 on the outside of the slewing bearing 2. The reducer On the top of 11 is an electric motor 12 connected to each other. The yaw transmission gear 10 of the reducer 11 meshes with the teeth 3 on the slewing support 2. The axis of the yaw transmission gear 10 is parallel to the center line of the slewing support 2; The inner edge of the slewing support 2 is provided with several bolts 13 along the circumferential direction of the slewing support 2, and the axes of the bolts 13 are also parallel to the center line of the slewing support 2; a rotation limit switch 6 and a position sensor are also arranged outside the slewing support 2 4. The gear 8 interconnected with the rotation limit switch 6 meshes with the teeth 3 on the slewing support 2 .

Abstract

The invention relates to a wind-driven generator, in particular to a yaw mechanism used on the wind-driven generator. The technical proposal provided by the invention is that annular pivoting supports which are mutually connected into a whole are arranged above an annular brake disc, the periphery of the pivoting supports is provided with teeth, and the invention is characterized in that: a reducer is arranged outside the pivoting supports, electric motors which are interconnected are arranged above the reducer, a yaw transmission gear of the reducer is meshed with the teeth on the pivoting supports, the axis of the yaw transmission gear is parallel to the center line of the pivoting supports; a plurality of bolts are arranged at the inner edge of the pivoting supports along the circumference direction of the pivoting supports, the axis of the bolts is also parallel to the center line of the pivoting supports; a train limit switch and a position transducer are further arranged outside the pivoting supports, a gear interconnected with the train limit switch is meshed with the teeth on the pivoting supports. The wind-driven generator of the invention can reduce the fatigue damage to a yaw gear box caused by frequent forward and reversing start.

Description

technical field [0001] The invention relates to a wind power generator, in particular to a yaw mechanism used on the wind power generator. Background technique [0002] During the working process of the wind turbine, the wind turbine must automatically face the wind and automatically yaw when it encounters strong wind, so as to achieve the purpose of automatic speed regulation and speed limit, so as to play the role of wind turbine self-protection and automatic wind effect. In the prior art, wind power generators adopt huge empennages, which are not suitable for use in large and medium-sized wind power generators. Contents of the invention [0003] The purpose of the present invention is to design a yaw mechanism of a wind power generator, so as to improve the bearing capacity of the yaw mechanism and reduce the fatigue damage to the yaw gearbox caused by frequent forward and reverse starts. [0004] According to the technical solution provided by the present invention, ...
