도 1 내지 도 3을 참조하면 본 발명 실시예는 일측면에 원주방향을 따라 베인(1)들의 회동축(3)이 회동 가능하게 삽입되는 축삽입홈(5)이 다수 구비된 제1링(7)과; 상기 제1링(7)의 축삽입홈(5)에 삽입되는 회동축(3)이 돌출되어 형성되고 상기 회동축(3)과 평행하게 가이드핀(9)이 돌출되어 형성된 다수의 베인(1)과; 상기 제1링(7)과 동심축을 이루어 결합되고, 상기 베인(1)들의 가이드핀(9)들이 각각 삽입되어 상기 제1링(7)과의 상대 회동시 상기 베인(1)을 상기 축삽입홈(5)을 중심으로 회동시키도록 형성된 다수의 캠홈(11)이 원주방향을 따라 배치된 제2링(13)을 포함하여 구성된다. 캠홈(11)은 제2링(13)의 일측면에 소정의 깊이로 함몰되고 방사형 방향에 대해 일정각도만큼 기울어지게 연장되며, 호 형상을 이루는 것이 바람직하다.1 to 3, an exemplary embodiment of the present invention includes a first ring having a plurality of shaft insertion grooves 5 in which rotation shafts 3 of vanes 1 are rotatably inserted along one circumferential direction. 7); A plurality of vanes (1) formed by protruding the rotation shaft (3) inserted into the shaft insertion groove (5) of the first ring (7) and protruding the guide pin (9) in parallel with the rotation shaft (3) )and; Coaxially coupled with the first ring (7), the guide pins (9) of the vanes (1) are respectively inserted so that the shaft insertion of the vanes (1) during relative rotation with the first ring (7) A plurality of cam grooves 11 formed to rotate about the groove 5 are configured to include a second ring 13 arranged along the circumferential direction. The cam groove 11 is recessed to one side of the second ring 13 to a predetermined depth, extends inclined by a predetermined angle with respect to the radial direction, and preferably forms an arc shape.
즉, 상호간에 상대 회동이 가능하게 결합되는 제1링(7)과 제2링(13)에 각각 축삽입홈(5)과 캠홈(11)이 형성되도록 하고, 여기에 베인(1)의 회동축(3)과 가이드핀(9)이 각각 삽입되도록 하여, 상기 제1링(7)과 제2링(13)의 상대 회동시 상기 베인(1)의 가이드핀(9)이 상기 캠홈(11)을 따라 이동하면서 상기 베인(1)의 회동을 유발시키도록 한 것이다. 즉, 제1링(7)이 회전되면, 축삽입홈(5)에 회동축(3)이 삽입된 상태에서 베인(1)의 위치 이동이 발생되고, 그에 따라 베인(1)의 가이드핀(9)은 캠홈(11)을 따라 슬라이딩 되면서 베인(1)의 회동이 발생되는 것이다.That is, the shaft insertion grooves 5 and the cam grooves 11 are formed in the first ring 7 and the second ring 13, which are coupled to each other so that relative rotation is possible, and the rotation of the vanes 1 is here. The coaxial 3 and the guide pin 9 are inserted so that the guide pin 9 of the vane 1 is the cam groove 11 when the first ring 7 and the second ring 13 rotate relative to each other. It is to cause the rotation of the vane (1) while moving along. That is, when the first ring 7 is rotated, the position movement of the vanes 1 is generated in a state where the rotation shaft 3 is inserted into the shaft insertion groove 5, and thus the guide pins of the vanes 1 9) is the rotation of the vanes (1) is generated while sliding along the cam groove (11).
따라서, 상기 베인(1)의 회동 특성은 상기 가이드핀(9)에 대한 캠홈(11)의 형상에 따라 조절될 수 있으며, 종래에 베인(1)의 선단부가 지나치게 터빈쪽으로 진입하여 간섭이 발생하게 되는 것을 방지하기 위해 별도의 스토퍼 등을 구비했던 것을, 별도의 스토퍼 없이 상기 가이드핀(9)과 캠홈(11)의 형상에 의해 제한하는 것이 가능 하므로, 상기 제2링(13)의 캠홈(11)은 상기 제1링(7)과 제2링(13)의 상대 회동시, 상기 베인(1)의 선단이 상기 제2링(13)의 내경부에 설치되는 터빈과 같은 회전체와 간섭하지 않도록 상기 가이드핀(9)의 이동을 제한하도록 형성된 구조로 하는 것이 바람직할 것이다.Therefore, the rotational characteristic of the vane 1 can be adjusted according to the shape of the cam groove 11 with respect to the guide pin 9, so that the tip of the vane 1 enters the turbine side too much and causes interference. Since it is possible to limit the one provided with a separate stopper or the like by the shape of the guide pin 9 and the cam groove 11 without a separate stopper, the cam groove 11 of the second ring 13 ) Does not interfere with a rotating body such as a turbine installed at the inner diameter of the second ring 13 when the vane 1 is rotated relative to the first ring 7 and the second ring 13. It will be desirable to have a structure formed so as to limit the movement of the guide pin (9).
상기 베인(1)은 상기 베인의 회동축(3)에 수직한 단면구조가, 도시된 바와 같이 단순한 직선 형상으로 형성될 수도 있지만, 도 6에 도시된 바와 같이 단면이 곡선이나 S 자형상 등 다양한 곡선 형상을 이루도록 형성되도록 할 수도 있다.The vane 1 may have a cross-sectional structure perpendicular to the pivot shaft 3 of the vane, as shown in FIG. 6, but may have a simple straight line shape.
