Abstract
The utility model relates to the technical field of hydraulic pressure and discloses a horizontal-axle type wind power main shaft of a wind driven generator; the horizontal-axle type wind power main shaft comprises a shaft body which comprises a big end (1) of the shaft body and a shaft-end flange (2), wherein the big end (1) of the shaft body is extended outwards and is divided into three sections which are transitional through chamfers (4); a transition section (3) between the big end (1) of the shaft body and the shaft-end flange (2) is circular arch-shaped; the shaft-end flange (2) is disc-shaped; the length of the big end (1) of the shaft body is about 2 meters; the diameter of the shaft-end flange (2) is about 1.5 meter; and a rust-proof oil layer is coated outside the shaft body. The horizontal-axle type wind power main shaft of the wind driven generator which has good quality and high stability and can be used for a long term is provided.
Description
Technical field
The utility model relates to technical field of wind power generation, relates in particular to the flat axle of a kind of wind-driven generator type wind power principal axis.
Background technique
In recent years, because the continuous scarcity of natural resources, the people comes for new energy, especially the development and use of clean energy resource are also more and more positive, and wherein, wind-power electricity generation is because of its clean environment firendly, the advantage renewable, pollution-free, that energy is big, prospect is wide becomes the strategic choice of countries in the world.
The wind power technology equipment is the important component part of wind-powered electricity generation industry, also be the basis and the guarantee of wind-powered electricity generation industry development, and wind power principal axis is as the core mechanical components of wind-driven generator, directly link to each other with fan blade, constitute the about 80-90 rice of diameter and get huge wind wheel, huge wind wheel is carrying natural wind and its energy is being passed to generator by the mechanical gear device and is being converted into electric energy.But because the restriction of physical environment makes the blade of huge wind wheel and wind power principal axis operating mode worsen, damage easily, and wind power principal axis is just had higher requirement to manufacturing and designing of wind power principal axis and technology as the core mechanical components of wind-driven generator.
Summary of the invention
After the wind power principal axis long-term work that exists in the prior art, operating mode worsens, the easy shortcoming of damaging, and it is good that the purpose of this utility model provides a kind of quality, and the stability height can use for a long time, the flat axle of the wind-driven generator of an environmental protection type wind power principal axis.
In order to solve the problems of the technologies described above, the utility model is solved by following technical proposals:
The flat axle of wind-driven generator type wind power principal axis comprises axis body, and described axis body comprises big end of axis body and boss, and the big end of axis body stretches out and is divided into three sections, passes through the chamfering transition between each section.
As preferably, the changeover portion between big end of axis body and the boss is a circular arc.Make wind power principal axis can with the generator better fit.
As preferably, boss is a disc.
As preferably, the big end length of axis body is 2 meters, and the boss diameter is 1.5 meters.
As preferably, axis body scribbles antirust oil reservoir outward.
As preferably, be entity in the axis body.Increase the stability of wind power principal axis, prolonged the service time of wind power principal axis.
According to the technical solution of the utility model, it is good that the flat axle of wind-driven generator type wind power principal axis has quality, stability height, the advantage that can use for a long time.
Description of drawings
Fig. 1 is embodiment's a structural representation.
Fig. 2 is the sectional drawing of Fig. 1.
Embodiment
Below in conjunction with accompanying drawing 1-2 and embodiment the utility model is described in further detail.
Embodiment
As shown in Figure 1, 2, the flat axle of a wind-driven generator type wind power principal axis comprises axis body, and described axis body comprises big end 1 of axis body and boss 2, and the big end 1 of axis body stretches out and is divided into three sections, passes through chamfering 4 transition between each section.Changeover portion 3 between big end 1 of axis body and the boss 2 is a circular arc.Make wind power principal axis can with the generator better fit.Boss 2 is a disc.The big end length of axis body is 2 meters, and the boss diameter is 1.5 meters.Axis body scribbles antirust oil reservoir outward.In the axis body is entity, has increased the stability of wind power principal axis, has prolonged the service time of wind power principal axis.
Implement according to above embodiment, it is good that the flat axle of wind-driven generator type wind power principal axis has quality, stability height, the advantage that can use for a long time.
In a word, the above only is preferred embodiment of the present utility model, and all equalizations of being done according to the utility model claim change and modify, and all should belong to the covering scope of the utility model patent.
