Description

technical field

[0001] The invention relates to wind power generating equipment, in particular to a novel full permanent magnetic levitation micro-friction wind power generator. Background technique

[0002] Wind energy is not only clean, environmentally friendly, and renewable, but also widely distributed, ubiquitous, and easy to use. It is a new type of energy with great development prospects. Moreover, people's use of wind power to generate electricity will not only have no negative impact, but will also bring the benefits of mitigating wind disasters, inhibiting desertification, and reducing or reducing the number and intensity of sandstorms.

[0003] People have a long history of understanding and utilizing wind energy. In the early days, windmills were mainly used to replace human beings for simple labor such as irrigation and pounding rice. At present, we use wind power to generate electricity, but the wind generated by nature not only changes in wind direction, but a...

Embodiment Construction

[0029] The present invention will be further described below in conjunction with accompanying drawing.

[0030] As shown in Figure 1, it is an embodiment of the present invention.

[0031] A traditional wind power generating set includes an impeller 1, a shaft 2, a mechanical bearing 3, and a generator 4, wherein the impeller 1 is generally arranged at one end of the shaft 2, the generator 4 is arranged at the other end of the shaft 2, and the two ends of the generator 4 are respectively arranged There are mechanical bearings3. Since the direction of the wind force is variable, the angle of the impeller 1 needs to be constantly changed to face the wind direction, and the shaft 2 is arranged on the frame through a mechanical rotating device.

[0032] Such a shaft structure is a typical cantilever beam structure. The shaft 2 will produce a certain amount of flexible deformation under the influence of the gravity of the impeller 1, and a non-axial force will be generated on the ...
