Transmission shaft on wind power generation equipment

Abstract

The invention provides a transmission shaft on wind power generation equipment. The transmission shaft comprises a first shaft body, a step part and a second shaft body which are sequentially and adjacently connected, wherein the outer diameter size of the step part is larger than that of the first shaft body and the second shaft body, and the outer diameter size of the first shaft body and the outer diameter size of the second shaft body are kept consistent; due to the adoption of the structure that a functional layer is arranged on the surface of the transmission shaft, a defect that the transmission shaft in the prior art is easy to wear is overcome, the wear resistance and the atmospheric corrosion resistance of the transmission shaft can be improved, and the service life of the equipment is prolonged; and the whole structure is scientific, reasonable, simple and compact, the installation and the use are convenient, remarkable economic and social benefits are achieved, and the transmission shaft is widely suitable for wind power generation.

Description

technical field [0001] The invention relates to wind power generating equipment, in particular to a drive shaft on the wind power generating equipment. Background technique [0002] As a clean and renewable energy, wind energy has been paid more and more attention by countries all over the world, and it is inexhaustible. It is very appropriate to use wind power to generate electricity according to local conditions; my country is rich in wind energy resources. According to statistics, the wind energy reserves that can be developed and utilized are about 1 billion kilowatts, of which the wind energy reserves on land are about 250 million kilowatts. The development prospect of wind power generation is very broad. [0003] The device required for wind power generation is called a wind turbine, which generally includes three parts: the wind rotor, the nacelle and the iron tower. The iron tower is the frame used to support the wind rotor, the tail cabin and the generator. The whee...
