Wind power generation is the use of converting the power of wind, which is natural energy, into electrical energy. will be.

In general, since wind is stronger the higher it is from the ground, it is advantageous to make the height of the wind turbine as high as possible, and the energy acquired by the wind turbine is proportional to the wind speed and the area to which the wind blows.

The characteristics of wind power generation are that it is a clean power generation system that does not emit environmental pollutants such as carbon dioxide or radioactive waste that can be seen in thermal or nuclear power generation when energy is obtained, and because it uses renewable energy called wind, energy resources are It has the advantage of being almost infinite.

At this time, the wind power generator 1 according to the prior art is a device for transmitting power from the blades to the generator, and includes a main shaft 2, and the main shaft can withstand harsh operating conditions such as continuous fatigue load and vibration. It is mainly produced by forging.

Specifically, the main shaft is upset by pressurizing steel ingots heated to a high temperature of about 1200 ° C in a heat treatment furnace with a hydraulic press, and then placing the material after the upsetting between the upper and lower dies of the hydraulic press to length It is repeatedly pressed along the direction (transversely). This is called cogging, and in this process, the thickness of the material becomes smaller and the length becomes longer. Thereafter, an approximate main shaft intermediate product is manufactured by repeatedly pressing the outer circumferential surface of the cogged material with a die to perform a finish forging operation.

Since the intermediate product formed in this way shows a significant difference from the final size of the main shaft required, it is completed as a final product through a cutting process such as roughing again.

Next, referring to FIG. 2, the main shaft 2 is required to transmit the rotational force of the rotor hub to which the blades are connected to the generator, and one side is connected to the rotor hub and the other side is connected to the gearbox. , The main shaft includes a main hole (3, deep hole) having a predetermined diameter (L1) therein.

Also, in general, the main shaft performs a boring process (boring chamfering process) to process the edge of the main hole 3 (deep hole).

At this time, the boring processing (boring chamfering processing) process for processing the edge of the main hole (3, deep hole) is performed in a dedicated chamfering device (large boring machine), and therefore, for this purpose, the middle of the main shaft Product movement is essential.

However, the movement of the intermediate product on the main shaft leads to a bottleneck between processes due to an increase in waiting time, etc., and eventually becomes a factor in increasing manufacturing cost due to an increase in process cost.

Meanwhile, a general main shaft may be manufactured as a final product by additionally performing processes such as semi-finishing, finishing, and final boring after the boring process. However, in the present invention, the main shaft manufacturing method It is not limiting.
