본 고안은 구면접촉 무단변속기에 과한 것으로 출력축에 형성된 구면원반과 입력축 선단에 형성된 보올클러치의 구면원반 사이에 2개의 구면마찰차를 대향지게 개재시켜 이들 구면마찰차의 구면접촉점 변화에 따라 입력축의 회전력이 출력축에 변속되어 전달되게 구성하므로서 기기의 간단함을 꾀하여 고장이 거의없도록하며, 소형이면서도 큰원동력을 정확하게 전달할 수 있도록 한것이다.The present invention is excessive to spherical contact continuously variable transmission, and the two spherical friction cars are interposed between the spherical disk formed on the output shaft and the spherical disk of the bowl clutch formed at the tip of the input shaft so that the rotational force of the input shaft changes according to the change of the spherical contact point of these spherical friction cars. It is designed to be transmitted to this output shaft, so that the device is simple and there is almost no failure, and it is possible to transmit small and large driving force accurately.

종래에는 주연부가 얇은 원반형 유성차에 의하여 무단변속 되게 구성된 것이 실용신안공보에 공고번호 75-175호로 제안된바 있으나, 이 경우는 입력축에 회전원반을 탄설하고 출력축에는 수개의 유성차를 메탈에 의하여 회전반경을 광협 이동되게 축설한 축수원통을 삽착하여 유성차의 내측연부가 회전원통과 원반간에 유성차가 감입되어 자전되면서 출력축을 회전케하고 기통 내벽으로는 양쪽으로 고정륜과 고정륜과 고정캠륜을 또 중앙부에는 이통캠륜을 장설하여 양쪽캠륜의 대향면에 각설된 캠간에 보올리테이나를 수장 구성하였으므로 그의 구조가 복잡하였다.Conventionally, it is proposed in the Utility Model Publication No. 75-175 that the periphery is configured to be continuously shifted by a thin disk-shaped planetary car, but in this case, a rotary disk is mounted on the input shaft and several planetary cars are mounted on the output shaft by metal. Insert the bearing cylinder with the rotation radius wide and move the inner shaft of the planetary car between the rotating cylinder and the disk to rotate the output shaft and rotate the output shaft on both sides of the inner wall of the cylinder. In addition, since the two wheels were installed in the center and the botete was built between the cams on the opposite surfaces of both cam wheels, the structure was complicated.

본 고안은 이러한 종래의 고안에 비하여 극히 구조가 간단하면서도 큰동력을 정확하게 전달할 수 있도록 안출한 것인바 이를 첨부도면에 의거 상세히 설명하면 다음과 같다.The present invention has been devised so as to accurately deliver a large power, yet extremely simple in structure compared to the conventional design, which will be described in detail based on the accompanying drawings.

기통(1)의 일측에 부착된 축수(2)에 축지되는 출력축(3) 선단에는 구면원반(4)을 형성하며, 타측에 부착된 축수(2a)에 축지되는 입력축(5) 선단에는 연축플랜지(5a)를 형성하여 거기에 연축구면원반(6)을 보올클러치(7)에 의하여 압지되게 축설하고 구면원반(4)과 연축구면원반(6) 사이에 2개의 구면마찰차(8),(9)를 대향지게 각 구면 마찰차(8),(9)의 구면(球面) (8a),(9a)이 구면원반(4)과 연축구면원반(6)의 구면(4a),(6a)에 구면 접촉하도록 구면마찰차(8),(9)를 축지구(10),(11)에 각각 축설하였다.A spherical disk (4) is formed at the tip of the output shaft (3) held by the shaft (2) attached to one side of the cylinder (1), and a soft flange at the tip of the input shaft (5) held by the shaft (2a) attached to the other side. (5a), and the soft spherical disc (6) is laid thereon to be pressed by the bowl clutch (7), and two spherical friction wheels (8) between the spherical disc (4) and the soft spherical disc (6); 9) The spherical surfaces 8a and 9a of each spherical friction difference 8 and 9 are spherical disks 4a and spherical disks 4a and 6a of the spherical spherical disk 6, respectively. The spherical friction cars 8 and 9 were arranged in the axial strip 10 and 11, respectively, so that spherical contact might be made.

축지구(10),(11)는 지지축(12),(13)의 하단에 "ㄱ"자 형으로 형성되었으며, 지지축(12),(13)은 나란히 입설되게 축지판(14)에 축설하여 그 상단에 축착된 호상치차(15),(16)에 의하여 회동되게 하는 한편 핸들(17)의 회전에 의하여 회전하는 워엄기어(18a)로 호상치차(15),(16)를 회동되게 하였다.The shafts 10 and 11 are formed at the bottom of the support shafts 12 and 13 in a "-" shape, and the support shafts 12 and 13 are mounted on the shaft plate 14 side by side. It is rotated by the eccentric gears 15 and 16 which are accumulated on its upper end and rotated by the worm gear 18a which is rotated by the rotation of the handle 17. It was.

그리고 보올클러치(7)는 연축플랜지(5a)면과 연축구면원반(6) 내면에 요설된 여러개의 원추형요홈(7a)에 보올(7b)이 각각 끼워져 있으며 연축구면원판(6)은 탄발력이 약한 코일스프링(6a)에 의하여 구면마찰차(8),(9)의 구면(8a),(9a)에 탄접되어 있고, 도면중 미설명부호 19는 메모리판이며, 20은 스냅링이고, 21은 오일유출공이다.And the bowl clutch (7) has a ball (7b) is fitted in the conical groove (7a) concave on the inner surface of the soft flange (5a) and the spherical spherical disk (6), respectively, and the spherical spherical disk (6) has a resilience The weak coil springs 6a are in contact with the spherical surfaces 8a and 9a of the spherical friction cars 8 and 9, where reference numeral 19 is a memory plate, 20 is a snap ring, and 21 is a Oil outflow hole.

이와같은, 본 고안은 구면원판(4)과 연축구면원반(6)의 구면(4a),(6a)에 구면마찰차(8),(9)의 구면(8a)(9a)이 접촉되어 있으므로 입력축(5)의 회전력은 출력축(3)에 전달되는데 제5도에서와 같이 구면마찰차(8),(9)의 구면(8a),(9a)과 구면원반(4) 및 연축구면원반(6)의 구면(4a),(6a)이 접촉하는 구면접촉점을 변화시키면 입력축회전력은 출려축에 변속하여 전달되므로 핸들(17)을 돌려 워엄기어(18a)에 축착된 지지축(12)을 회동시키면 지지축(12)과 함께 회전하는 호상치차(15)의 회동으로 호상치차(15)에 치합된 호상치차(16)가 지지축(12)의 회동방향과 반대방향을 회전하면서 지지축(13)을 회동시켜 각 구면마찰차(8),(9)의 구면접촉경사를 고정시켜 정확한 변속효율을 발휘한다.As such, the present invention is because the spherical surfaces 4a and 6a of the spherical disk 4 and the spherical spherical disk 6 are in contact with the spherical friction wheels 8 and 9a. The rotational force of the input shaft 5 is transmitted to the output shaft 3, and as shown in FIG. 5, the spherical friction wheels 8 and 9 and the spherical disks 8a and 9a and the spherical disk 4 and the soft spherical disk If the spherical contact point contacted by the spherical surfaces 4a and 6a of 6) is changed, the input shaft rotational power is transmitted by shifting to the drawer shaft, so that the support shaft 12 which is fixed to the worm gear 18a is rotated by turning the handle 17. The support shaft 13 rotates in a direction opposite to the rotational direction of the support shaft 12 when the interlock gear 16 meshed with the interlock gear 15 is rotated by the interlock gear 15 rotating together with the support shaft 12. ), The spherical contact inclination of each spherical friction car (8), (9) is fixed to achieve accurate shifting efficiency.

이때 입력축(5)이 회전하면 보올(7b)은 원추형효홈(7a) 내에서 외방으로 이동하면서 연축구면원반(6)을 구면마찰차(8),(9) 쪽으로 밀어붙이므로 보다 정확하고 큰 동력의 변속 효율을 기대할 수 있다.At this time, when the input shaft 5 rotates, the bowl 7b moves outward in the conical groove 7a and pushes the soft spherical disk 6 toward the spherical friction cars 8 and 9 so that the power is more accurate and larger. Expected shifting efficiency.

이와같이 본 고안은 구면원반(4) 및 연축구면원반(6)과 구면마찰차(8),(9)의 구면접촉을 스프링으로 밀지않고 보울클러치(7)의 조압(調壓)으로 강력하게 밀어붙이므로 종래의 무단변속기에 비하여 큰 동력을 정확하게 전달할 수 있고, 구조가 극히 간단하므로 고장이 거의 없으며 소형으로 제작할 수 있는 등 여러가지 이점이 있는 실용적인 고안인 것이다.In this way, the present invention does not push the spherical contact between the spherical disk (4) and the spherical spherical disk (6) and the spherical friction car (8), (9) with a spring, but strongly pushed by the coercive force of the bowl clutch (7) As a result, it is possible to transmit large power accurately compared to the conventional continuously variable transmission, and since the structure is extremely simple, there is almost no failure and it is a practical design with various advantages, such as being made compact.
