Abstract
The utility model belongs to the technical field of hydraulic pressure, and discloses a high-capacity high-speed wind power main shaft which comprises a shaft body; the shaft body is provided with a large shaft body end (1) and a shaft end flange (2); the shaft end flange (2) is disc-shaped; a transition section (3) between the large shaft body end (1) and the shaft end flange (2) is circular arc-shaped; the interior of shaft body is solid; the length of the large shaft body end is 2 m; the diameter of the shaft end flange is 1.5 m; and an anti-rust oil layer is painted outside the shaft body. The high-capacity high-speed wind power main shaft has the advantages of good quality, capability of long-term use, and high capacity of a motor.
Description
Technical field
The utility model relates to technical field of wind power generation, relates in particular to a kind of high-capacity and high-speed 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, can use for a long time, and capacity motor is big, the high-capacity and high-speed wind power principal axis of environmental protection.
In order to solve the problems of the technologies described above, the utility model is solved by following technical proposals:
The high-capacity and high-speed wind power principal axis comprises axis body, and described axis body comprises big end of axis body and boss.
As preferably, boss is a disc.
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, be solid body in the axis body.Increase the stability of wind power principal axis, prolonged the service time of wind power principal axis.
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.
According to the technical solution of the utility model, it is good that wind power principal axis has quality, can use the advantage that capacity motor is big for a long time.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is a sectional drawing of the present utility model.
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 high-capacity and high-speed wind power principal axis comprises axis body, and described axis body comprises big end 1 of axis body and boss 2.Boss 2 is a disc.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.In the axis body is solid body, has increased the stability of wind power principal axis, has prolonged the service time of wind power principal axis.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.The capacity motor of this high-capacity and high-speed wind power principal axis is 1.5 megawatts.
Implement according to above embodiment, it is good that wind power principal axis has quality, can use the advantage that capacity motor is big 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.
