본 고안은 VTR 및 DAT와 같은 자기테이프를 사용하는 기기에서 테이프의 주행속도를 조절하기 위한 아이들기어에 구동력을 전달하는 아이들 클러치에 관한 것이다.The present invention relates to an idle clutch that transmits a driving force to an idle gear for adjusting the running speed of a tape in a device using magnetic tape such as VTR and DAT.
통상적으로 사용되는 VTR 및 DAT는 음성 및 영상을 녹화, 재생하는 작업을 수행하게 되는데 작동중 테이프의 주행속도를 가변해야 할 필요가 있다. 즉 플레이 모드시나 레코드 모드시에는 테이프의 주행속도가 정상적인 회전속도를 유지하여야 하나 패스터포드(Fast Forde) 모드시나 리와인드(Rewing) 모드시에는 테이프의 주행속도가 정상적인 플레이 모드시의 주행속도 보다 2배 이상 빠른 속도로 주행하게 된다.VTR and DAT are generally used to record and play back audio and video, but it is necessary to vary the running speed of the tape during operation. In other words, the tape running speed should be maintained in the play mode or the record mode. However, the tape running speed in the Fast Forde mode or the Rewind mode is 2 times that of the normal play mode. You will travel more than twice as fast.
이러한 동작을 수행함에 있어서 종래에는 캡스턴 모터의 구동력을 아이들기어 까지 전달함에 있어서 다수개의 폴리 및 기어를 연동되게 작동시킬 수 있도록 하여 사용하여 왔다.In performing such an operation, a plurality of pulleys and gears have been used so as to be linked with each other in transmitting a driving force of a capstan motor to an idle gear.
그러나 이와같은 종래의 기구장치는 다수개의 풀리 및 기어가 평면상에 배열되어 필요에 따라 접속되며 구동하므로 설치 면적이 매우 넓어지고 복잡해 지므로 기구의 소형경량화 시키는데 장애가 되었다.However, such a conventional mechanism device has a obstacle in miniaturization and weight of the apparatus because a plurality of pulleys and gears are arranged on a plane, connected and driven as necessary, and thus the installation area becomes very wide and complicated.
본 고안은 이와같은 문제점을 해소하기 위하여 안출된 것으로서 설치면적을 줄이고 구동력을 정확하게 전달할 수 있도록 하여 기구를 소형 경량화시키며, 제품의 신뢰성을 향상시키는데 본 고안의 목적이 있다.The present invention has been devised to solve such a problem, it is the purpose of the present invention to reduce the installation area and to accurately transmit the driving force to reduce the size and weight of the device, and to improve the reliability of the product.
상기 목적을 수행하기 위한 실시예를 첨부된 도면에 의거 상세히 설명하면 다음과 같다.An embodiment for carrying out the above object will be described in detail with reference to the accompanying drawings.
캡스턴 모터의 구동력을 전달받은 풀리(1)와 연동되도록 설치되어 있는 기어(2)가 설치된 축(3)에 상기 기어(2)와 동일한 외주와 모듈을 갖는 기어(4)를 설치하되 상기 기어(2, 4) 사이에는 상하면에 휄트(5a, 5b)가 부착된 휄트부착판(6)을 설치하고 기어(4) 상면에 형성된 기어(7)는 아이들기어(8)와 치합되게 설치하되 상기 기어(2, 4)는 캠레버(9)의 작동에 의해 축(10)을 중심으로 회전하는 레버(11)에 설치된 접속기어(12)와 접속 또는 치합되도록 하여서 된 것으로서 도면중 미설명 부호 13은 스프링, 15는 일방향 스프링 클러치이다.Gears (4) having the same outer periphery and module as the gears (2) are installed on the shaft (3) on which the gears (2), which are installed to interlock with the pulley (1) receiving the driving force of the capstan motor, are installed. Between the 2 and 4, a bolt attachment plate 6 with bolts 5a and 5b is installed on the upper and lower surfaces, and the gear 7 formed on the upper surface of the gear 4 is installed to be engaged with the idle gear 8, but the gear (2, 4) is to be connected or engaged with the connecting gear 12 installed on the lever 11 that rotates about the shaft (10) by the operation of the cam lever 9, reference numeral 13 in the drawings The spring 15 is a one-way spring clutch.
이와같이 구성된 본 고안의 작용효과는 우선 정상적인 플레이 모드시에는 접속기어(12)가 기어(2, 4)로 부터 분리된 상태에 있다. 이와같은 상태에서는 캡스턴 모터로 부터 구동력을 전달받은 풀리(1)에 의해 회전력을 전달받은 기어(2)가 회전하며 기어(4)에 동력을 전달하게 되는데 이때 상기 기어(2)와 기어(4) 사이에는 휄트(5a, 5b)가 상하면에 부착된 휄트부착판(6)에 의해 동력이 전달된다. 즉 기어(2)의 회전력이 휄트(5b)와의 마찰력에 의해 휄트받침판(6)을 회전시키면 휄트(5a)와 기어(4)의 마찰력에 의해 기어(4)가 구동하여 기어(7)와 치합된 아이들기어(8)를 구동시키게 되는 것이다. 그러나 이때에는 기어(2)의 구동력을 기어(4)에 전달시에 동력의 손실이 커져 구동속도가 트리게 된다. 즉 정상적인 플레이 모드시의 회전속도를 유지하게 되는 것이다.The working effect of the present invention configured as described above is in a state in which the connecting gear 12 is separated from the gears 2 and 4 in the normal play mode. In this state, the gear 2, which receives the rotational force by the pulley 1, which receives the driving force from the capstan motor, rotates to transmit power to the gear 4, wherein the gear 2 and the gear 4 are rotated. Power is transmitted by the bolt attachment plate 6 attached to the upper and lower surfaces of the bolts 5a and 5b. That is, when the rotational force of the gear 2 rotates the bolt support plate 6 by the frictional force with the bolt 5b, the gear 4 is driven by the frictional force of the bolt 5a and the gear 4 to engage with the gear 7. The idle gear 8 is driven. However, at this time, the loss of power increases when the driving force of the gear 2 is transmitted to the gear 4, and the driving speed is increased. In other words, the rotational speed in the normal play mode is maintained.
이와같은 상태에서 회전속도를 빠르게 동작시키고자 할 경우에는 캠레버(9)를 제3도 (a)에서와 같이 화살표 방향으로 이동시키면 레버(11)는 스프링(13)의 탄력이 의해 축(10)을 중심으로 시계방향으로 회전하면서 접속기어(12)가 기어(2)와 기어(4)를 동시에 접속하게 된다. 이와같은 상태에서는 풀리(1)의 회전력을 전달받은 기어(2)가 구동하면 이와 치합된 접속기어(12)가 구동함에 따라 상측에 맞물린기어(4)가 회전하게 된다.In this state, in order to operate the rotational speed quickly, the cam lever 9 is moved in the direction of the arrow as shown in FIG. 3 (a), and the lever 11 is moved to the shaft 10 by the elasticity of the spring 13. ), The connecting gear 12 connects the gear 2 and the gear 4 simultaneously. In this state, when the gear 2 receiving the rotational force of the pulley 1 is driven, the gear 4 engaged to the upper side is rotated as the connecting gear 12 engaged thereto is driven.
즉 기어(2)의 회전력이 직접기어(4)로 옮겨져서 힘의 낭비가 없이 기어(4)는 기어(2)와 동일한 속도를 가지며 회전하게 된다.That is, the rotational force of the gear 2 is transferred directly to the gear 4 so that the gear 4 rotates at the same speed as the gear 2 without waste of force.
즉 FF모드 또는 리와인드 모드시의 주행을 할 수 있게 되는 것이다.That is, driving in the FF mode or the rewind mode can be performed.
특히 리와인드 모드시에는 모타의 회전을 역방향으로 구동시켜 동력을 전달하게 되므로 풀리 및 기어의 회전방향이 역방향으로 구동하게 되는바 이때에는 일방향 스프링 클러치(15)의 작동으로 보다 큰 토크를 낼 수 있게 된다.Particularly, in the rewind mode, the motor rotates in the reverse direction to transmit power, so the rotation direction of the pulley and the gear is driven in the reverse direction. In this case, the torque of the one-way spring clutch 15 can produce more torque. .
이와같은 상태에서 릴 디스크를 정속으로 회전시키고자 할 경우에는 제3도 (b)와 같이 캠레버(9)를 화살표 방향으로 밀게되면 캠레버(9)의 미끄러면(9a)에 레버(11)의 끝단(11')가 미끄러지면서 캠레버(9)의 하단면(9b)에 위치하게 됨에 따라 레버(11)는 축(10)을 중심으로 반시계 방향으로 회전하면서 접속기어(12)가 기어(2, 4)로 부터 분리된다.In this state, when the reel disk is to be rotated at a constant speed, as shown in FIG. 3 (b), when the cam lever 9 is pushed in the direction of the arrow, the lever 11 is provided on the sliding surface 9a of the cam lever 9. End 11 'of the cam lever 9 is positioned on the bottom surface 9b of the cam lever 9, so that the lever 11 rotates counterclockwise about the shaft 10 and the gear 12 is geared. Separated from (2, 4).
이후에는 기어(2)의 구동력이 기어(4)로 전달되는 과정은 전술한 바와같다.After that, the process of transmitting the driving force of the gear 2 to the gear 4 is as described above.
상기한 바와같이 본 고안에 의하면 구조에 의하여 릴 디스크를 구동하게 되므로 기기를 소형 경량화 시킬 수 있으며 정확한 동력 전달에 의해 기기의 신뢰성을 향상시킬 수 있게 된다.As described above, according to the present invention, the reel disk is driven by the structure, so that the device can be light and small in size, and the reliability of the device can be improved by accurate power transmission.
