본 고안은 자기기록 및 재생기기의 유성치차를 이용한 감속자치에 관한 것으로, 특히 브이씨알과 오디오기기등의 가전제품에서 캠기어의 구동에 적합하게한 유성치차를 이용한 감속장치에 관한 것이다.The present invention relates to a deceleration autonomous using planetary gears of magnetic recording and reproducing apparatus, and more particularly, to a deceleration apparatus using planetary gears suitable for driving cam gears in home appliances such as V-Cal and audio equipment.

종래 브이씨알등의 가전제품에 있어서는 캠기어에 형성된 와권상 캠홈의 변위변화를 이용하여 연동부품이 구동되게한 캠구동장치는 채용되고 있으며, 캠기어에 충분한 구동력이 전달되도록 구동원(예로서 모터)의 회전력이 감속장치를 거쳐서 캠기어에 전달되도록 되어있다.Conventionally, in home appliances such as V-Cal, a cam driving device is adopted in which an interlocking part is driven by using a displacement change of a vortex cam groove formed in a cam gear, and a driving source (e.g., a motor) is used to transmit a sufficient driving force to the cam gear. Torque is transmitted to the cam gear through the reduction gear.

종래 캠구동을 위한 감속장치는 제 1 도에 예시한 바와같이, 치차열을 이용하여 캠기어를 감속구동시켰다.In the conventional speed reduction device for cam driving, as shown in FIG. 1, the gear gear is decelerated and driven using a gear train.

제 1 도의 21-26은 치차를 나타내는데 직접 구동원(27)에 직접연결되어 있는 치차(21)의 구동력이 그보다 치수가 많고 피치원이 큰 치차(22)에 전달되고 이는 동축의 치차(23)의 동일한 회전에 의해 다시 치차(24)에 전달되며 그 치차(24)와 동일축인 치차(25)에 의해 캠기어(28)와 맞물린 치차(26)에 전달되어 최종적으로 캠기어(28)가 구동된다.21-26 of FIG. 1 shows a gear, in which the driving force of the gear 21 directly connected to the direct drive source 27 is transmitted to the tooth 22 having a larger dimension and a larger pitch circle, which is the same as that of the coaxial gear 23. It is transmitted to the gear 24 again by the same rotation and is transmitted to the gear 26 meshed with the cam gear 28 by the gear 25 which is coaxial with the gear 24, and finally the cam gear 28 is driven. do.

그러나 이러한 감속기구는 손쉽게 감속비를 얻을 수 있으나, 중간치차열이 차지하는 면적으로 인하여 구동원(27)과 캠기어(28)의 거리가 떨어지고 중간에 치차수에 해당하는 축의 설치가 필요하게 되므로 제품을 소형경량화하기 어렵고 부품비가 상승하고 부품교환작업이 어려운 문제점이 있었다.However, such a reduction mechanism can easily obtain a reduction ratio, but because the area occupied by the intermediate gear row decreases the distance between the driving source 27 and the cam gear 28 and requires the installation of an axis corresponding to the dimension in the middle. It was difficult to reduce the weight, the parts cost was increased, and there was a problem that the parts replacement work is difficult.

본 고안은 이와같은 종래의 결함을 해소하기 위하여 창안한 것으로, 캠기어의 하부에 소치차 일체형 대치차를 동일축으로 축착하고 소치차와 캠기어의 내주면에 형성한 내치차 사이에 유성치차를 설치하여 점유면적이 감소되고 간소화된 감속장치를 제공하기 위한 것인바, 이러한 본 고안을 첨부한 도면에 의하여 상세히 설명하면 다음과 같다.The present invention was devised to solve such a conventional deficiency, and the planetary gear is fitted between the gear and the internal gear formed on the inner circumferential surface of the cam gear on the lower side of the cam gear. To reduce the occupied area and to provide a simplified deceleration device, the present invention will be described in detail by the accompanying drawings as follows.

제 2 도 및 제 3 도에 도시한 바와같이. 캠기어를 이용한 구동기구가 채용된 자기기록 및 재생장치에 있어서, 상면에 캠홈(1)이 형성된 캠기어(2)이 하측부에 내치차(3)를 형성하고 부시(4)를 개재하여 캠기어(2)가 축착되도록 베이스플레이트(5)에 고정한 축(6)의 하측부에는 소치차(7) 일체형 대치차(8)를 축착하며, 그 대치차(8)를 구동원(9)에 연결된 구동치차(10)에 치합시킴과 아울러 소치차(7)와 캠기어(2)의 내치차(3) 사이에 유성치차(11)를 설치한 것이다.As shown in FIG. 2 and FIG. In a magnetic recording and reproducing apparatus employing a drive mechanism using a cam gear, a cam gear 2 having a cam groove 1 formed on an upper surface thereof forms an internal tooth 3 on a lower side thereof and a cam 4 through a bush 4. The lower gear 6 fixed to the base plate 5 is fixed to the lower part of the shaft 6 fixed to the base plate 5, and the small gear 8 is integrally connected to the driving source 9. The planetary gear 11 is provided between the small gear 7 and the inner gear 3 of the cam gear 2 while being engaged with the driving gear 10.

이와같은 본 고안은 직접구동원〈캠기어 구동을 위한 전용모터(9)의 구동치차(10)〉 또는 제 2 차 구동원(예를들면 캡스턴 모터의 동력을 벨트로 전달받아 캠기어측에 전달하는 구동풀리)로부터 회전력을 내치차(8)로 전달받아 동심으로 형성되어있는 소치차(7)가 함께 회전하고 소치차(7)는 그보다 치수가 많은 유성치차(11)에 회전력을 전달하며, 유성치차(11)는 캠기어(2)에 최종회전력을 전달하여 캠기어(2)가 회전한다.This invention devises a direct drive source <drive gear 10 of a dedicated motor 9 for driving a cam gear> or a secondary drive source (for example, a drive that receives the power of a capstan motor to a belt and transmits it to a cam gear side). Receives the rotational force from the pulley) to the inner tooth (8) and the toothed gear (7) formed concentrically rotates together, the toothed gear (7) transmits the rotational force to the planetary gear 11 having a larger dimension, the planetary gear 11 transmits the final rotational force to the cam gear 2 to rotate the cam gear (2).

여기서 각 치차(10,8,7,11,3)의 치수를 N1-N6라고 한다면 소치차(7)의 유성치차(11)의 회전비는,이므로 구동치차(10)로부터 최종 캠기어(2)까지의 감속비는,가 된다.Here, if the dimensions of each gear 10,8,7,11,3 are N 1 -N 6 , the rotation ratio of the planetary gear 11 of the small gear 7 is Therefore, the reduction ratio from the drive gear 10 to the final cam gear 2 is Becomes

따라서, 본 고안 감속자치는 동력전달과 회전감속(회전력 증대)를 동시에 행하게 된다.Therefore, the present invention deceleration autonomously performs power transmission and rotation deceleration (increase in rotational power).

결국, 이상에서 설명한 바와같은 본 고안은 캠기어와 동일축으로 소치차 일체형 대치차를 축착학 유성치차를 이용하여 구동력이 감속전달되게되어 있으므로 캠기어의 축과 구동치차의 축사싱에 치차 및 축을 설치할 필요가 없게되어 점유면적이 감속되고 사용부품수가 절감되면서 조립 및 부품 교환이 용이하게 되는 이점이 있다.As a result, the present invention as described above, since the driving force is transmitted to the gear shaft integral shaft with the same axis as the cam gear by using the axial planetary gear, the gear and the shaft of the shaft of the cam gear and the driving gear are decelerated. Since there is no need to install, the occupied area is reduced, and the number of parts used is reduced, thereby making it easy to assemble and replace parts.
