On the other hand, wind power generation is divided into horizontal wind power generation using horizontal wing structure and vertical wind power generation using vertical wing. The above-mentioned horizontal wind power is generated by rotating a large horizontal wing (three pieces), and is mainly used in an area with strong wind power. On the other hand, in the vertical wind power generation, the wind power can be generated even by the slower wind than the horizontal wind power. However, in order to reduce the mechanical friction loss due to the large size of the wing and the weight of the body supporting the wind power, The material is a situation in which lightweight plastic-based materials such as polycarbonate are used.

하우징(10)에 Y축 방향으로 회전가능하게 지지되고, 제1자성체(13)와 상호 자력을 발생시킬 수 있도록, 제1자성체(13)와 대응되는 제2자성체(15)가 일정거리를 유지하여 외주연에 장착되는 수직축(16)을 구비하여,The second magnetic body 15 corresponding to the first magnetic body 13 maintains a predetermined distance so as to be rotatably supported in the Y-axis direction and to generate mutual magnetic force with the first magnetic body 13. With a vertical axis 16 mounted on the outer periphery,

블레이드(11) 회전시 제1,2자성체(13,15)간의 척력 및 인력에 의해 수평축(12)의 회전력이 수직축(16)에 전달되어 수직축(16)을 회전시키도록 구성된다.When the blade 11 rotates, the rotational force of the horizontal axis 12 is transmitted to the vertical axis 16 by the repulsive force and the attraction force between the first and second magnetic bodies 13 and 15 to rotate the vertical axis 16.

이때 바람직하게는, 전술한 제1,2자성체(13,15)는 영구자석으로 이뤄진다.In this case, preferably, the above-described first and second magnetic bodies 13 and 15 are made of permanent magnets.

In the drawings, reference numerals a and b denote bearings that respectively support the rotating plate 14 and the vertical shaft 16 to the housing 10 so as to be rotatable.

이하에서, 본 발명의 일 실시예에 의한 영구자석을 이용한 풍력발전기용 회전력 전달장치의 사용예를 첨부도면을 참조하여 상세하게 설명한다.Hereinafter, an example of the use of the rotational force transmission device for a wind power generator using a permanent magnet according to an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

도 1 내지 도 3에서와 같이, 전술한 블레이드(11)가 일단에 설치된 수평축(12) 타단에 장착된 회전판(14)을 베어링(a)에 의해 하우징(15)에 X축 방향으로 회전가능하게 결합한다. 이때 회전판(14)에 원주방향으로 형성된 안착홈(17)에 N극 및 S극을 갖는 제1자성체(13)(영구자석이 사용됨)가 교대로 반복하여 장착된다.As shown in FIGS. 1 to 3, the rotating plate 14 mounted on the other end of the horizontal shaft 12 installed at one end of the blade 11 is rotatably rotated in the X-axis direction to the housing 15 by the bearing a. To combine. At this time, the first magnetic body 13 (permanent magnet is used) having the N pole and the S pole is alternately repeatedly mounted in the mounting groove 17 formed in the circumferential direction on the rotating plate 14.

전술한 하우징(15)에 장착된 베어링(b)에 의해 수직축(16)을 Y축 방향으로 회전가능하게 결합하되, 수직축(16)의 외주연에 원주방향으로 형성되는 안착홈(18)에 제1자성체(13)와 대응되는 N극,S극을 갖는 제2자성체(15)(영구자석이 사용됨)가 교대로 반복하여 각각 장착된다.The vertical shaft 16 is rotatably coupled in the Y-axis direction by a bearing b mounted on the housing 15, and is provided in the seating groove 18 formed in the circumferential direction at the outer circumference of the vertical shaft 16. The second magnetic body 15 (permanent magnet is used) having the N-pole and the S-pole corresponding to the one magnetic body 13 is alternately repeatedly mounted.

따라서, 전술한 블레이드(11)의 회전에 따라 수평축(12)이 연동되어 회전되므로 회전판(14)이 X축 방향으로 회전된다. 회전판(14)에 원주방향으로 장착된 다수의 제1자성체(13)와, 이와 대응되게 수직축(16) 외주연에 장착된 제2자성체(15)간에 발생되는 상호 척력 및 인력에 의해 수직축(16)을 Y축 방향으로 회전시킬 수 있다.Therefore, since the horizontal axis 12 is interlocked and rotated according to the rotation of the blade 11 described above, the rotating plate 14 is rotated in the X-axis direction. The vertical shaft 16 is formed by mutual repulsion and attraction generated between the plurality of first magnetic bodies 13 circumferentially mounted on the rotating plate 14 and the second magnetic bodies 15 mounted on the outer circumference of the vertical axis 16 correspondingly. ) Can be rotated in the Y-axis direction.

전술한 바와 같이 풍력에 의해 회전되는 블레이드(11) 회전시 연동되어 회전되는 수평축(12)의 회전력을 무접점 방식에 의해 연결되는 수직축(16)에 전달할 수 있게 된다. 이로 인해 동력전달부품의 상호 마찰로 인한 에너지손실을 줄여 풍력발전 효율을 향상시킨다. 또한 동력전달부품 상호간의 기계적인 접촉마찰로 인한 소음, 진동, 열 발생을 줄여 내마모성 확보로 사용수명을 연장할 수 있다.
As described above, the rotational force of the horizontal shaft 12 that is linked and rotated when the blade 11 rotated by the wind power can be transmitted to the vertical shaft 16 connected by the contactless method. This reduces the energy loss due to mutual friction of power transmission components, thereby improving wind power efficiency. In addition, noise, vibration, and heat generated by mechanical contact friction between power transmission parts can be reduced, and service life can be extended by securing wear resistance.

도 4는 본 발명의 일 실시예에 의한 영구자석을 이용한 풍력발전기용 회전력 전달장치에서, 블레이드를 회전가능하게 지지하는 하우징이 풍향에 따라 시계 방향 또는 반시계 방향으로 유동됨을 보여주는 도면이다.Figure 4 is a view showing a rotational force transmission device for a wind turbine using a permanent magnet according to an embodiment of the present invention, the housing for rotatably supporting the blade flows in a clockwise or counterclockwise direction according to the wind direction.

전술한 수직축(16)을 회전가능하게 지지하는 제1하우징(20a)과, 회전판(14)을 회전가능하게 지지하는 제2하우징(20b)으로서 하우징(20)을 분리형성하되, 제1,2하우징(20a,20b)은 제1하우징(20a)의 외측면과 제2하우징(20b)의 내측면사이의 밀착면에 장착된 베어링(c)에 의해 상대 회전운동을 하도록 결합된다. 이때 제1하우징(20a)의 상면과 제2하우징(20b)의 바닥면사이의 밀착면에 원주방향으로 등간격으로 장착된 볼베어링(d)에 의해 회전운동을 지지한다.The housing 20 is separately formed as a first housing 20a rotatably supporting the above-described vertical axis 16 and a second housing 20b rotatably supporting the rotating plate 14. The housings 20a and 20b are coupled to each other in a relative rotational motion by a bearing c mounted on the contact surface between the outer surface of the first housing 20a and the inner surface of the second housing 20b. At this time, the rotary motion is supported by a ball bearing (d) mounted at equal intervals in the circumferential direction on the contact surface between the upper surface of the first housing (20a) and the bottom surface of the second housing (20b).

이로 인해, 전술한 하우징(20;20a,20b)이 풍향에 따라 수직축(16)을 중심으로 시계 방향 또는 반시계 방향으로 동일평면상에서 유동할 수 있게 된다.
As a result, the above-described housings 20; 20a and 20b may flow on the same plane in the clockwise or counterclockwise direction about the vertical axis 16 according to the wind direction.

한편, 전술한 블레이드(11)의 회전력으로 수평축(12), 수직축(16)을 연동시켜 회전시킴에 따라 발전기의 회전자(미도시됨)를 구동시켜 발전하는 구성은, 본원발명이 속하는 기술분야에서 사용되는 기술내용이므로 이들의 구성에 대한 상세한 설명은 생략한다.On the other hand, the configuration of driving the rotor (not shown) of the generator as the rotational force of the horizontal axis 12, the vertical axis 16 by the rotational force of the above-described blade 11 to generate power, the technical field to which the present invention belongs.

A horizontal axis rotated by a blade rotation mounted at one end;
A rotating plate connected to the other end of the horizontal axis, the blade being rotatably supported in the X-axis direction when the blade is rotated, and having a plurality of first magnetic bodies made of permanent magnets mounted circumferentially on an outer surface thereof;
The second magnetic body is rotatably supported on the housing in the Y-axis direction, and is formed on the outer circumference of the second magnetic body made of a permanent magnet corresponding to the first magnetic body so as to generate mutual magnetic force with the first magnetic body. In the rotational force transmission device for a wind turbine having a vertical axis, to generate power by driving the rotor of the generator by the blade rotational force:
The first magnetic body is alternately repeatedly mounted with a permanent magnet having an N pole and an S pole in a plurality of seating grooves formed in the circumferential direction on the outer surface of the rotating plate;
The second magnetic body is mounted in the circumferential direction on the outer periphery of the vertical axis, and the permanent magnets having N poles and S poles are alternately repeatedly mounted, respectively, so that the repulsive force between the first and second magnetic bodies is rotated when the blade is rotated. And a rotational force of the horizontal shaft by the attraction force to the vertical shaft to rotate the vertical shaft. 삭제delete 삭제delete
