본 고안은 비데오 카세트 레코오더의 릴 디스크(Reel Disk)를 플레이(Play)시와, 퍼워드(Forward)나 리와인드(Rewind)시에 따라 회전 속도를 변속시켜 주는 아이들러클러치(Idler Cluth)의 변속 장치에 관한 것으로, 아이들러클러치이 상측클러치와, 전동플리가 일체로 형성된 하측클러치 사이에 같은 극성을 지닌 두개의 디스크 마그네트(Disk Magnet)를 압축 스프링으로 설치하여 플레이시 압축 스프링의 압착력에 의해 디스크 마그네트 사이에 발생되는 서로 밀어내는 자기력으로 슬립(Slip)을 유발시켜 회전속도를 감속시킴으로써 항상 일정한 토오크를 관리하도록한 VTR의 아이들러 클러치 슬립 유발장치에 관한 것이다.The present invention shifts the rotation speed of the reel disk of the video cassette recorder at the time of Play, and the forward or rewind of the idler clutch. In this regard, the idler clutch has two disk magnets having the same polarity between the upper clutch and the lower clutch in which the electric pulley is integrally formed with a compression spring. The present invention relates to an idler clutch slip inducing device of a VTR that induces a slip with a generated magnetic force to reduce the rotational speed so that a constant torque is always managed.
종래에는 플레이시 릴 디스크에 전달되는 회전 속도를 감속시키기 위해 아이들러클러치의 전동플리가 일체로 형성된 하측 클러치이 상부에 세레이션을 가공하고, 상, 하측 클러치 사이에 디스크펠트를 설치하여 상, 하측 클러치에 슬립현상을 유발시킴으로 감속시켰는데 장기간 사용하다 보면 디스크 펠트의 마모현상으로 상측 클러치의 속도가 증가되어 정상적인 플레이 작동이 되지 못하는 결점이 있었다.Conventionally, in order to reduce the rotational speed transmitted to the reel disk during play, the lower clutch, which is integrally formed with the electric fleece of the idler clutch, processes the serration on the upper side, and a disk felt is installed between the upper and lower clutches to provide the upper and lower clutches with the upper and lower clutches. It slowed down by causing slip phenomenon, but the long-term use caused the disc felt to wear and the upper clutch speed increased, which prevented normal play.
따라서 본 고안은 상기에서와 같은 결점을 감안하여 상, 하측 클러치 사이에 압축 스프링과 같은 극성을 지닌 두개의 디스크 마그네트를 설치하여 플레이시 항상 일정하게 발생되는 자기력으로 슬입을 유발시켜 감속시키는 토오크를 관리할 수 있도록 한 VTR의 아이들러 클러치 슬립 유발장치를 제공하기 위한 것이다.Therefore, the present invention manages the torque to decelerate by inducing a slip by the magnetic force that is constantly generated during play by installing two disc magnets having the same polarity as the compression spring between the upper and lower clutches in view of the above drawbacks. It is to provide an idler clutch slip inducing device of the VTR.
본 고안을 첨부된 도면에 의하여 상세히 설명하면 다음과 같다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.
제1도와 제2도는 본 고안이 요부 분해 사시도와 작동 상태를 도시한 것으로 아이들러(6)가 회동되도록 결합되고 아이들러클러치(1)를 구성시키는 지지판(7)의 구동축(5)에 통상의 구동체(4)와 상측클러치(3)를 순차적으로 결합시킨 후 압축 스프링(9)(a')가 통공(12)이 형성된 디스크 마그네트(10)를 결합시키며 전동풀리(8)가 일체로 형성된 하측클러치(2)의 내부 상측에 통공(13)이 형성된 디스크 마그네트(11)를 통상의 방법으로 접착시킨 다음 하측 클러치(2)를 구동축(5)에 통상이 결합방법으로 회동되도록 결합시킨 것이며 상기의 디스크 마그네트(10)(11)는 같은 극성을 지니도록 구성하고 상기의 구동체(4)는 아이들러(6)와 접촉되어 동력을 전달시키도록 구성하며 전동풀리(8)와 도시하지 않은 캡스틴 플라이 휘일을 벨트(19)로 연결시켜 구성한 것이다.1 and 2 show the principal part exploded perspective view and the operating state of the present invention, in which the idler 6 is pivotally coupled to the drive shaft 5 of the support plate 7 constituting the idler clutch 1, which is a common driving body. Combination (4) and the upper clutch (3) in sequence after the compression spring (9) (a ') is coupled to the disk magnet (10) formed with the through hole 12, the lower clutch integrally formed with the electric pulley (8) The disk magnet 11 having the through hole 13 formed on the upper side of the inner part 2 is bonded in a conventional manner, and then the lower clutch 2 is coupled to the drive shaft 5 so as to be rotated in a conventional coupling method. The magnets 10 and 11 are configured to have the same polarity, and the driving body 4 is configured to be in contact with the idler 6 to transmit power, and the electric pulley 8 and the capstin fly wheel not shown. Is configured by connecting the belt (19).
도면중 미설명부호 18은 샤프트 레버이고, 14, 15, 16은 통공이며 17은 연결핀이다.In the figure, reference numeral 18 is a shaft lever, 14, 15, 16 are through holes and 17 is a connecting pin.
이러한 구성으로 이루어진 본 고안은 상, 하측 클러치(2)(3)사이에 압축스프링(9)(9')과 같은 극성을 지닌 디스크 마그네트(10)(11)를 설치하여 플레이시 항상 일정하게 발생되는 자기력으로 슬립을 유발시켜 감속시키는 토오크를 관리할 수 있도록 하는 것으로써, 제2도에 도시한 바와같이 퍼워드나 리와인드시 도시하지 않은 틸디스크를 구동시킬 때에는 압축스프링(9)(a')에 의해 상측 클러치(9)가 밀려 있는 상태에서 먼저 통상의 슬라이드판을 슬라이딩시켜 샤프트 레버(18)를 하측으로 회동시키면 상측클러치(3)는 하측클러치(2)에 결합되고 도시하지 않은 캡스턴 모타로 구동되는 캡스턴 플라이 휘일의 벨트(19)에 의해 전동풀리(8)가 회전되어 직접상측의 구동체(4)를 회전시킴으로 아이들러(6)를 회전시켜 릴디스크를 회전시키는 것이다.The present invention made up of such a configuration is provided between the upper and lower clutches (2) (3) between the disc magnets (10) (11) having the same polarity as the compression spring (9) (9 '), and always occurs constantly during play. By controlling the torque to induce slip by decelerating magnetic force, as shown in FIG. 2, when driving a tilt disk (not shown) during forwarding or rewinding, as shown in FIG. When the upper clutch 9 is pushed by, the first slide plate is slid to rotate the shaft lever 18 downward, and the upper clutch 3 is coupled to the lower clutch 2 and is not shown in the capstan motor. The electric pulley 8 is rotated by the belt 19 of the capstan flywheel being driven to rotate the idler 6 by rotating the drive body 4 directly on the upper side to rotate the reel disk.
이때 압축스프링(9)(9')은 압축되며 구동체(4)의 통공(16)내에 상측클러치(3)와 일체로 형성시킨 연결핀(17)이 삽입되어 있어서 상측 클러치(3)가 하측으로 슬라이딩되어도 구동체(4)를 회전시키는 것이다.At this time, the compression springs 9 and 9 'are compressed and the connecting pin 17 formed integrally with the upper clutch 3 is inserted into the through hole 16 of the driving body 4 so that the upper clutch 3 is lowered. Even if it slides, the drive body 4 is rotated.
그리고 릴 디스크를 플레이 시킬때에는 제3도의 (a)(b)에 도시한 바와 같이 도시하지 않은 슬라이드판을 슬라이딩시켜 샤프트 레버(18)를 상측으로 회동시키면 상측클러치(3)는 압축스프링(9)(9')의 탄성력에 의해 하측클러치(2)로 부터 이탈되어 상승되고 벨트(19)에 의해 하측클러치(2)를 회전시키면 회전 속도가 직접 상측의 구동체(4)에 전달되지 않고 압축스프링(9)(9')이 상측의 디스크 마그네트(10)를 하측의 디스크 마그네트(10)(11)사이에 발생되는 서로 밀어내는 자기력으로 슬립을 유발시켜 회전속도를 감소시킴으로써 상측의 구동체(4)는 감속된 회전속도로 아이들러(6)를 회전시켜 릴 디스크를 구동시킴으로 항상 정상적인 플레이가 수행되는 것이다.When the reel disk is played, as shown in (a) and (b) of FIG. 3, the slide plate (not shown) is rotated and the shaft lever 18 is rotated upward, so that the upper clutch 3 has the compression spring 9 When the lower clutch 2 is lifted away from the lower clutch 2 by the elastic force of 9 'and the lower clutch 2 is rotated by the belt 19, the rotation speed is not directly transmitted to the upper drive body 4, but the compression spring is (9) (9 ') causes the slip by the magnetic force which pushes the upper disk magnet 10 between the lower disk magnets 10, 11 to each other to reduce the rotational speed, thereby reducing the rotational speed 4 ) Rotates the idler 6 at a reduced rotational speed to drive the reel disk so that normal play is always performed.
즉 플레이시 상, 하측 클러치(2)(3)사이에서 슬립을 유발되어 감속되도록 같은 극성의 디스크 마그네트(10)(11)를 압축스프링(9)(9')으로 압축시켜 회전시킴으로 회전속도를 감속시키는 것이다.That is, the rotation speed is increased by compressing and rotating the disk magnets 10 and 11 of the same polarity with the compression springs 9 and 9 'so as to cause slippage between the upper and lower clutches 2 and 3 during play. It is to slow down.
따라서 디스크 마그네트(10)(11)는 항상 일정하게 발생되는 자기력으로 슬입을 유발시켜 감속시키는 토오크를 관리할 수 있도록 하는 것이다.Therefore, the disk magnets 10 and 11 are able to manage the torque to decelerate by causing the slip to always be a constant magnetic force generated.
위에서 상술한 바와 같은 본 고안은 종래 하측클러치 상부에 세레이션을 가공하고 상측클러치 사이에 압축스프링과 디스크 펠트를 설치 사용하여 발생되는 디스크 펠트의 마모 현상으로 회전 속도를 감속시키는 토오크를 관리하지 못해 정상적인 플레이를 수행시키지 못했던 결점을 해결시켜 항시 정상적인 플레이를 수행시킬 수 있는 효과가 제공되는 것이다.As described above, the present invention does not manage torque that slows down the rotational speed due to the wear of the disk felt caused by processing the serration on the upper lower clutch and installing the compression spring and the disk felt between the upper clutch. It solves the defect that did not perform play and the effect which can always perform normal play is provided.
