Equipped with gears. A shaft is passed through the center of the shaft, and a generator at the tip of the shaft is attached. The speed of the low speed of the wind turbine can be increased to the rated speed required for power generation on the large gear and small gear, and in addition, a constant When the low speed is exceeded due to strong winds above the wind speed, the shaft at the center of the small gear that uses this independent pillow block is automatically separated by several millimeters along with the generator. However, although the large gear and the small gear are spun off by being connected, the generator stops rotating and prevents damage. Therefore, it is possible to control the rotation of the generator without the need for special discs and brakes, and it is possible to install multiple generators.

In particular, wind turbine generators that have been put into practical use have a rated speed of 900 to 1,750, and at least 20 to 60 times the speed of wind power is required, and a wind speed of 12 m / s or more is essential. It is difficult to reduce the size of the machine, and most of the discs and brakes are used for control in strong winds. The overall equipment is complicated, and it is the most familiar, ranging from 2KW to 20KW for general households and small businesses. There was a drawback that required small wind generators could not be put into practical use.

As an improvement, there is a method of using speed increase by gears, which can easily generate power even if the rotation speed is low due to wind speed or hydraulic power. (1) Sound is easily generated even when gears are accelerated. (2) While the large gear fixed to the windmill is rotating, the connected small gear cannot be removed. There are necessary and disadvantages.

Control. 26 is a thrust bearing that supports the entire wind power generator, a radial bearing 27 is small and 28 is supported by a large radial bearing, and supports vertical stability. The windmill 1 is always made to face in the wind blowing direction.

FIG. 4 is a partial use explanatory diagram (A). 11 large gears and 12 small gears are connected. The small gear 12 is made of a pillow block shaft 39, which is independently designated by 17 pillow block double bearings, and the pillow block shaft 39 has 38 single balls. There is a ball and it is made to withstand the presser foot from the right.

Regardless of whether the blade is a propeller type or a vertical blade type, it is impossible to spread a small practical wind generator unless the performance, efficiency, and safety are improved by 2 to 3 times compared to the conventional method. A wind generator is a generic term that includes the performance of a wind turbine and the generator, but the wind turbine and the generator are separate from the manufacturer. Therefore, the improvement of the generator performance is indispensable for improving the performance of the wind turbine as a whole because the performance of the wind turbine is 40% and the performance of the generator is about 60%. Although the invention of this application is a gear speed increasing method, it enables wind speed rotation and free speed increasing transmission of the generator, greatly increasing the power generation efficiency and devising a structure without a disc brake that is not necessary for small wind power generators. As a result, it is possible to significantly improve performance and reduce costs, while the conventional product requires a wind speed of 10-12 m / s or more, but the product of the present invention has load power generation at a wind speed of 7 m / s (meaning to use electric power). Therefore, it can be used on the rooftops of coastal areas and urban areas. Therefore, it is possible to spread from 1KW to 20KW as a practical small wind generator with a strong wind of 7m / s or less, and it can be widely used as a distribution product worldwide, from general households to light industries, and to help improve the use of natural energy. It can be used for a periodical wind power generator, and has a significant positive effect on the industry.
