본 고안은 VTR의 드럼모터 회전력 전달장치에 관한 것으로서, 더욱 상세하게는 VTR의 드럼모터 회전력을 회전부위인 비디오 헤드측으로 전달할때 충격을 완충시키고 예압을 균일하게 유지할수 있도록 한 것이다.The present invention relates to a drum motor rotational force transmission device of the VTR, and more particularly, to cushion the shock and maintain the preload uniformly when the drum motor rotational force of the VTR is transmitted to the video head side of the rotating portion.
종래에는 제1도에 나타낸 바와같이, 축(7)상에 베어링(8)으로 지지된 하부드럼(9)의 하부에 플랜지부(10)가 설치되고, 상기 하부드럼(9)의 상부에 순차적으로 원뿔형의 와셔(5a)와 셋트스크류(2)로 체결되는 링칼라(1a)가 상기축(7)에 삽입된다.Conventionally, as shown in FIG. 1, the flange portion 10 is provided at the lower portion of the lower drum 9 supported by the bearing 8 on the shaft 7, and sequentially on the upper portion of the lower drum 9. A ring collar 1a fastened by a conical washer 5a and a set screw 2 is inserted into the shaft 7.
따라서, 링칼라(1a)의 상부면에 정압(P)을 가하여 상기 링칼라(1a)의 하부에 설치된 원뿔형 와셔(5a)의 탄성력으로 필요한 적정예압을 유지시킨후에 상기 링칼라(1a)에 체결되는 셋트스크류(2)를 이용하여 상기 링칼라(1a)와 그 하부의 플랜지부(10)를 고정시킨다.Therefore, the positive pressure P is applied to the upper surface of the ring collar 1a to maintain the proper preload necessary by the elastic force of the conical washer 5a installed under the ring collar 1a, and then fastened to the ring collar 1a. Using the set screw (2) to fix the ring collar (1a) and the flange portion 10 of the lower portion.
그러면, 링칼라(1a)에 고정되는 드럼모터(도시하지않음)의 회전력이 상기 링칼라(1a)하부에 설치된 원/뿔형의 와셔(5a)를 통하여 베어링(8)과의 적정예압을 유지하면서 상기 링칼라(1a)를 통해 플랜지부(10)로 전달된다.Then, the rotational force of the drum motor (not shown) fixed to the ring collar 1a is maintained while maintaining the proper preload with the bearing 8 through the circular / conical washer 5a provided below the ring collar 1a. It is transmitted to the flange portion 10 through the ring collar (1a).
그러나, 이와같은 종래의 링칼라(1a)와 원뿔형의 와셔(5a)는 각각 다른 기능을 수행하는 2가지의 부품이므로 조립이 불편했다.However, these conventional ring collars 1a and conical washers 5a are two parts each having a different function, and thus, assembly is inconvenient.
또한, 원뿔형의 와셔(5a)는 금형작업후의 열처리, 경도 및 탄성의 유지 및 흠집발생등 부품생산시의 문제가 많이 발생되고, 조립시의 예압불균일, 자동화의 어려움 및 베어링과의 접촉시의 충격에 약한 등의 많은 문제점이 있었다.In addition, the conical washer 5a has many problems in the production of parts such as heat treatment after mold work, maintenance of hardness and elasticity, and scratches, and there is a preload unevenness during assembly, difficulty in automation, and impact on contact with bearings. There were many problems, such as weak.
본 고안은 상기한 제반 문제점을 해결하기 위한 것으로서, 본 고안은 VTR의 드럼모터의 회전력을 회전부위인 비디오 헤드측으로 전달할때 충격을 완충시킬 수 있을 뿐만 아니라, 예압을 균일하게 유지할 수 있는 VTR의 드럼모터 회전력 전달장치를 제공하는데 그 목적이 있다.The present invention is to solve the above-mentioned problems, the present invention can not only cushion the shock when transmitting the rotational force of the drum motor of the VTR to the video head side of the rotating portion, the drum of the VTR that can maintain the preload uniformly The purpose is to provide a motor torque transmission device.
상기한 목적을 달성하기 위해 본 고안은 상부링칼라의 저면부위에 설치된 탄성링과, 상기 탄성링에 접속되어 탄성링의 적정예압을 유지시키는 하부링칼라로 구성된 VTR의 드럼모터 회전력 전달장치이다.The present invention to achieve the above object is a drum motor rotational force transmission device of the VTR consisting of an elastic ring installed on the bottom portion of the upper ring collar, and a lower ring collar connected to the elastic ring to maintain a proper preload of the elastic ring.
이하, 본 고안의 일시시예를 첨부된 도면 제2도 내지 제5도를 참조하여 상세히 설명하면 다음과 같다.Hereinafter, a temporary example of the present invention will be described in detail with reference to FIGS. 2 to 5.
제2도는 본 고안에 따른 링칼라의 분해사시도이고, 제3도는 제2도의 결합상태를 나타낸 단면도이며, 제4도는 본 고안의 사용상태이며, 제5도는 본 고안의 다른 실시예를 나타낸 도면이다.Figure 2 is an exploded perspective view of the ring collar according to the present invention, Figure 3 is a cross-sectional view showing a coupling state of Figure 2, Figure 4 is a state of use of the present invention, Figure 5 is a view showing another embodiment of the present invention .
상부링 칼라(1)의 일측에 셋트스크류(2)로 체결시킬 수 있는 체결공(3)이 형성되고, 상기 상부링칼라(1)의 저면 중앙부는 오목하게 들어간 요입홈(4)이 형성되어 상기 요입홈(4)에 정압(P)에 의해 변형되어 적정예압을 유지시키며, 정압(P)이 제거된 후에 본래의 형상으로 복원되는 탄성링(5)이 고정된다.A fastening hole 3 capable of fastening with a set screw 2 is formed at one side of the upper ring collar 1, and a center of the bottom surface of the upper ring collar 1 is recessed with a concave recess 4. The elastic ring 5 which is deformed by the positive pressure P to maintain the proper preload and is restored to its original shape after the positive pressure P is removed is fixed to the recessed groove 4.
또한 상부링칼라(1) 저면중앙의 고정턱(4)에 고정된 탄성링(5)의 하부에는 하부링칼라(6)가 상기 상부링칼라(1)의 저면중앙에 삽입되어 축(7)으로서 고정되도록 구성된다.In addition, the lower ring collar 6 is inserted into the center of the bottom surface of the upper ring collar 1 in the lower portion of the elastic ring 5 fixed to the fixing jaw 4 of the lower center of the upper ring collar 1 and the shaft 7. It is configured to be fixed as.
이와같이 구성된 본 고안은 제2도 내지 제5도에 나타낸 바와같이, 축(7)상에 베어링(8)으로 지지된 하부드럼(9)의 하부에 플랜지부(10)가 설치되고, 상기 하부드럼(9)의 상부에는 저면 내측에 탄성링(5)과 하부링칼라(6)가 삽입된 상부링칼라(1)가 상기 축(7)에 삽입된다.According to the present invention configured as described above, as shown in FIGS. 2 to 5, the flange portion 10 is installed at the lower portion of the lower drum 9 supported by the bearing 8 on the shaft 7, and the lower drum is provided. The upper ring collar (1) into which the elastic ring (5) and the lower ring collar (6) are inserted is inserted into the shaft (7) in the upper part of the bottom.
따라서, 상부링칼라(1)의 상부면에 정압(P)을 가하여 상기 상부링칼라(1)의 저면내측에 삽입된 하부링 칼라(6)사이에 설치된 탄성링(5)의 탄성력으로 필요한 적정예압을 유지시킨후에 상기 상부링칼라(1)의 일측에 형성된 체결공(3)에 체결되는 셋트스크류(2)를 이용하여 상기 상부링칼라(1)와 그 하부의 플랜지부(10)를 고정시키게 된다.Therefore, applying a positive pressure (P) to the upper surface of the upper ring collar (1) titration necessary for the elastic force of the elastic ring (5) provided between the lower ring collar (6) inserted into the bottom inner side of the upper ring collar (1) After maintaining the preload, the upper ring collar 1 and the lower flange 10 are fixed by using a set screw 2 fastened to the fastening hole 3 formed at one side of the upper ring collar 1. Let's go.
그러므로, 상부링칼라(1)에 고정되는 드럼모터(도시하지 않음)의 회전력이 상기 상부링칼라(1)와 그 저면 내측에 순차적으로 삽입고정된 탄성링(5)과 하부링칼라(6)를 통해 베어링(8)과의 적정예압을 유지함과 동시에, 플랜지부(10)에 회전력을 전달할 수 있게 된다.Therefore, the rotational force of the drum motor (not shown) fixed to the upper ring collar 1 is elastic ring 5 and the lower ring collar 6 which are sequentially inserted and fixed inside the upper ring collar 1 and its bottom surface. Through maintaining the proper preload with the bearing (8), it is possible to transmit the rotational force to the flange (10).
또한 본 고안의 다른 실시예로서, 상부링칼라(1)의 저면 외측둘레의 고정홈(7)과 하부링칼라(6) 상면 외측둘레의 고정홈(7a)사이에 탄성링(5)을 설치함으로써 접착제를 사용하지 않고 손쉽게 결합시켜서 사용할 수 있다.In addition, as another embodiment of the present invention, the elastic ring 5 is installed between the fixing groove 7 of the outer peripheral surface of the bottom of the upper ring collar (1) and the fixing groove (7a) of the upper outer peripheral surface of the lower ring collar (6) Thus, it can be easily combined without using an adhesive.
한편, 본 고안을 모터 및 임의의 회전력 전달장치에 적용해서 사용할 수 있음은 이해 가능한 것이다.On the other hand, it is understood that the present invention can be applied to a motor and any rotational force transmission device.
이상에서와 같이, 본 고안은 상부링칼라(1)와 하부링칼라(6)로 분리하여 그 사이에 탄성체인 탄성링(5)을 설치하여 일체형으로 함으로써, VTR의 드럼모터 회전력을 회전부위인 비디오 헤드측으로 전달시의 충격을 완충시키고 예압을 균일하게 유지할 수 있어서 제품의 효율성 및 신뢰성을 대폭 향상시킨 매우 유용한 고안이다.As described above, the present invention is to separate the upper ring collar (1) and the lower ring collar (6) by installing an elastic ring (5), which is an elastic body therebetween, so that the drum motor rotational force of the VTR is a rotational part It is a very useful design that greatly improves the efficiency and reliability of the product by buffering the shock during transmission to the video head and maintaining the preload uniformly.
