Embodiment Construction

[0048] Hereinafter, the principles and specific embodiments of the present invention will be described with reference to the accompanying drawings.

[0049] figure 1 A wind turbine according to an embodiment of the invention is schematically shown. The wind turbine according to the present invention comprises a tower 1 erected in the vertical direction and a nose 2 extending in the horizontal direction on the top of the tower 1 . The wind energy received by the wind rotor (not shown) is transmitted down through the wind turbine according to the invention (see below) to a generator or other energy consuming equipment (not shown) located at any desired height including the ground. exist figure 1 In , the tower structure and the nacelle of the nose are shown in dashed lines. When the power generated by the wind turbine is transmitted to the generator to generate electricity through the power transmission system (indicated by the solid line), the wind generator of the present i...

Abstract

The invention discloses a coupler assembly, a power transfer system, a wind turbine and a wind driven generator. An input shaft can rotate around the axis of the input shaft and swing round a swing axis, and comprises at least two input shaft sections with different phases. An output shaft can rotate around the axis of the output shaft and comprises at least two output shaft sections with different phases. The coupler assembly has a central axis and comprises a central coupler which is arranged around the central axis in a concentric way and at least one periphery coupler; and each of the central coupler and the periphery couplers comprises a first member and a second member which are integrated and can integrally do translational motion along the direction of the central axis. The first member of the central coupler can swing around the central axis, and the first member of each periphery coupler can swing around an adjacent inner coupler. The input shaft, the coupler assembly and the output shaft are connected with one another by using a motion conversion device. Therefore, power can be stably transferred to any expected height from high height.

Description

technical field [0001] The present invention relates to a coupling assembly, a power transmission system including the coupling assembly, a wind turbine including the power transmission system, and a wind generator including the wind turbine. Background technique [0002] In order to protect the living environment of the earth and realize the sustainable development of energy, countries all over the world are investing a lot of manpower, material and financial resources to actively develop and utilize clean energy. As a clean energy, wind energy has become the most important research and development object. At present, various wind power generators have been developed. [0003] Traditional wind turbines generally consist of a wind turbine that receives wind energy and a generator that converts wind energy into electrical energy. The wind turbine and generator are packaged in a nacelle to form the nose, and then installed on the top of the tower through a rotating support d...
