본 고안은 회전체의 역회전방지장치에 관한 것으로써 특히 동력전달기구중 동력전달기어 역회전 방지장치에 관한 것이다.The present invention relates to a reverse rotation prevention device of the rotating body, and more particularly to a power transmission gear reverse rotation prevention device of the power transmission mechanism.
종래에도 동력전달기구의 역회전방지를 목적으로 제3도의 도시와 같이 랙크기어(10)와 랙크발톱(20)을 설치하여 주동체(30)에 역회전부하가 걸릴 경우 회전되지 못하도록 하였으나, 주동체의 급작스런 역회전시 과부하가 걸리면 그 충격에 의해 랙크기어 또는 랙크발톱이 파손되는 단점이 있었으며, 정회전시에도 랙크기어와 랙크발톱은 항상 접촉되어 있으므로 소음이 발생되는 문제점이 있어 정교한 전자제품의 내부장치 또는 사용할 수 없는 폐단이 있었다.Conventionally, in order to prevent the reverse rotation of the power transmission mechanism, as shown in FIG. 3, the rack gear 10 and the rack claw 20 are installed to prevent the rotation of the main body 30 when the reverse rotation load is applied. In case of sudden overturning of the fuselage, there is a disadvantage that the rack gear or rack claw is damaged by the impact, and the rack gear and the rack claw are always in contact with each other even in the forward rotation, causing noise. There was a device or closure that was not available.
본 고안은 이러한 종래의 제폐단점 및 문제점을 해소하기 위해 안출한 것으로서, 스프링을 이용하여 동력전달 및 역회전을 방지할 수 있게 한 것이다.The present invention has been devised to solve such a problem and problems of the conventional, it is possible to prevent power transmission and reverse rotation by using a spring.
이를 첨부도면에 의거 상세히 설명하면 다음과 같다.This will be described in detail based on the accompanying drawings.
브라켓트(8)에 고정된 고정축(7)상에 종동기어(1)와 동력전달기어(2)가 유삽되어 각 기어보스(1')(2') 외주면으로 스프링(3)을 연결하되, 종동기어보스(1') 외주면에서만 스프링(3)의 일단부가 용접고정되고, 동력전달 기어보스(2') 외주면에는 억지 끼워진다.The driven gear 1 and the power transmission gear 2 are inserted on the fixed shaft 7 fixed to the bracket 8 to connect the spring 3 to the outer circumferential surface of each gear boss 1 ', 2', One end of the spring 3 is welded and fixed to the outer circumferential surface of the power transmission gear boss 2 'only on the outer circumferential surface of the driven gear boss 1'.
종동기어(1')는 모터축 또는 레바(6) 축에 고정시킨 구동기어(4)와 치합되며, 동력전달기어(2)에는 주동기어(5)가 치합된다.The driven gear 1 'is meshed with the drive gear 4 fixed to the motor shaft or the lever 6 shaft, and the main gear 5 is meshed with the power transmission gear 2.
미설명 부호(9)는 멈춤링이다.Reference numeral 9 is a stop ring.
이와같이 구성된 본 고안은 모터 또는 레바(6)를 회전시켜 구동기어(4)에 회전력이 발생하게 되면 이에 치합된 종동기어(1)가 회전되면서 기어보스(1')상에 일단이 고정된 스프링(3)도 따라 회전하게 되어 동력전달된 기어(2)의 기어보스(2')상에 억지끼워진 스프링(3)부의 내경이 축소됨으로써 기어보스(2') 외주면과 스프링(3) 내경이 면접촉 압착되어 동력전달기어(2)가 회전하게 된다.When the rotational force is generated in the drive gear 4 by rotating the motor or the lever 6, the present invention configured as described above has a spring fixed at one end on the gear boss 1 'while the driven gear 1 engaged thereto rotates. 3) the inner diameter of the spring 3, which is forcibly fitted on the gear boss 2 'of the power transmission gear 2, is reduced according to the rotation of FIG. The power transmission gear 2 rotates by being compressed.
따라서 이에 치합된 주동기어(5)가 회전하게 되는 것이며, 주동기어(5)에 급작스런 역회전 부하가 걸리게 되면 이에 치합된 동력전달기어(2)가 역방향으로 회전되어 기어보스(2') 외주면에 내경이 축소되어 압착되었던 스프링(3)과의 사이에서 슬립되는데, 이는 스프링(3)의 나선방향과 반대방향으로 기어보스(2')가 회전되기 때문이다.Therefore, the main gear gear 5 engaged therein is rotated. When a sudden reverse rotation load is applied to the main gear gear 5, the power transmission gear 2 engaged thereto is rotated in the reverse direction to the outer peripheral surface of the gear boss 2 '. The inner diameter is reduced and slips between the springs 3 which have been compressed because the gear boss 2 'is rotated in the opposite direction to the spiral direction of the springs 3.
따라서 회전력은 종동기어(1)에 전달되지 않고 동력전달기어(2)만 헛돌게 되는 것이다.Therefore, the rotational force is not transmitted to the driven gear 1, and only the power transmission gear 2 turns away.
이와같이 주동기어(5)의 급작스런 역회전시 발생하는 과부하에 의한 충격이 동력전달기어(2)에 의해 소멸되고 타기어에는 전달되지 않기 때문에 파손의 우려가 있고, 소음발생이 없으며, 동력전달과 차단이 스프링에 의해 이루어지도록 되어 있어 그 구조가 간단하게 된 매우 유용한 고안이다.In this way, the shock caused by the overload generated during sudden reverse rotation of the main gear 5 is extinguished by the power transmission gear 2 and is not transmitted to the other gear. It is designed to be made by this spring, which is a very useful design that simplifies its structure.
