본 고안은 비데오 테이프 레코더의 로오딩 장치의 일부분인 서플라이 링치차 및 테이크업 링치차에 모우터의 회전력을 전달하기 위한 구동장치에 관한 것이다.The present invention relates to a driving device for transmitting a rotational force of a motor to a supply ring tooth and a take-up ring tooth which are part of a loading device of a video tape recorder.
종래의 로오딩 장치는 서플라이 링치차와 테이크업 링치차의 구동장치를 모우터로 구동함에 있어 정지되어 있던 구동장치를 모우터로 일순간에 여유없이 구동시키도록 되어 있기 때문에 모우터가 시동할 때 정지되어 있는 상태의 구동장치의 관성에 의해 많은 부하가 걸리게 되어 모우터 회전에 큰 무리가 뒤따르게 되는 결점이 있었다.The conventional loading device stops when the motor starts because the driving device of the supply ring tooth and the take-up ring tooth is driven by the motor in a moment. Due to the inertia of the driving device in a state of being loaded, a large load is applied, resulting in a large crowd following the rotation of the motor.
본 고안은 종래 이러한 문제점을 해결하기 위하여 풀리와 워엄의 결합부 위에 여유공간을 두어 모우터가 시동할때 처음 일순간은 여유공간내에서 공회전을 시켜 모우터의 시동에 무리가 없도록 하고 일단 회전이 시작된 다음에 구동장치의 부하가 걸리도록 함으로써 모우터의 시동을 원활하게 하며, 서플라이링 치차를 구동하는 구동치차는 중앙부에 결여홈을 두고 그 상·하부에 치차를 형성함으로서 테이크업 링치차의 구동 치차와 균형있는 치합이 이루어 지도록 한것으로, 이를 도면에 따라 상세히 설명하면 다음과 같다.In order to solve the above problems, the present invention places a free space on the coupling part of the pulley and the worm to start idle the first moment when the motor is started so that there is no difficulty in starting the motor and once the rotation is started. Next, the motor is smoothly started by applying a load to the driving device, and the driving gear for driving the supply gear has a groove in the center and a gear in the upper and lower parts thereof, thereby driving the take-up ring gear. Balanced to be made with, as described in detail according to the drawings as follows.
모우터(M)의 회전력을 전달받는 풀리(1)와 워엄(2)을 결합하고 이 워엄(2)에 워엄휠(3)을 치합하며 워엄 휠(3)의 축(4)에 테이크업 구동치차(5)를 고정하고 테이크업 구동치차(5)에 서플라이 구동치차(6)를 치합한 다음, 테이크업 구동치차(5)및 서플라이 구동치차(6)에 테이크업 링치차(7) 및 서플라이 링치차(8)를 치합하여서 된 통상의 구동장치에 있어서, 상기 풀리(1)의 내측에 축(1″)을 중심으로 돌기(1')를 대향 형성하고 이와 결합되도록 상기 워엄(2)의 축공 일단에는 여유공간(2') 및 걸림턱(2″)을 형성하며, 서플라이 구동치차(6)는 길게 형성하여 그 중앙에 결여홈(6')을 두어 상·하 치차(6a)(6b)를 구분 형성한다음, 이들 상·하치차(6a)(6b)에 테이크업 구동치차(5)의 상·하부위가 치합되도록 하여 테이크업 링치차(7)가 상기 결여홈(6')에 의해 서플라이 구동장치(6)와 접촉되지 않도록 구성한 것으로, 미설명부호 9는 브래키트이다.The pulley (1) and the worm (2), which receive the rotational force of the motor (M), are combined, and the worm wheel (3) is fitted to the worm (2), and the take-up driving is performed on the shaft (4) of the worm wheel (3). Fix the gear 5 and engage the supply drive gear 6 with the take-up drive gear 5 and then take up ring gear 7 and the supply with the take-up drive gear 5 and the supply drive gear 6. In the conventional driving device formed by engaging the ring teeth (8), the worm (2) is formed so as to face the projection (1 ') about the shaft (1 ") on the inner side of the pulley (1) and to be coupled thereto. A free space 2 'and a hooking jaw 2 ″ are formed at one end of the shaft hole, and the supply drive gear 6 is formed long and has a missing groove 6' at the center thereof so that the upper and lower teeth 6a ( 6b) and then, the upper and lower teeth 6a and 6b are engaged with the upper and lower portions of the take-up driving gear 5 so that the take-up ring tooth 7 is not provided with the lacking groove 6 '. Supply drive by It is configured not to be in contact with (6), and reference numeral 9 is a bracket.
이와 같이 구성된 본 고안은 제4도와 같이 풀리(1)의 돌기(1')가 워엄(2)의 여유공간(2')과 걸림턱(2″)에 결합되어 있기 때문에 모우터(M)가 처음 회전을 시작할때 풀리(1)의 돌기(1')가 여유 공간(2')만큼 일단 공회전한 다음 걸림턱(2″)에 걸려 구동장치의 워엄(2)을 회전시켜 주도록 되어 있어 모우터(M)가 처음 시동할 때는 일단 여유공간 만큼 공회전을 하기 때문에 부하가 안걸린 상태에서 회전하므로 모우터의 시동이 원활하며 일단 시동된 다음 구동장치의 부하가 걸리므로 이때는 어느정도 큰 부하라도 모우터의 회전에 무리를 주지 않으므로 모우터의 손상을 방지하게 된다. 또한 서플라이 구동치차(6)를 상·하 치차(6a)(6b)로 나누어 그 사이에 결여홈(6')을 형성함으로서 테이크업 링치차(7)가 결여홈(6')을 통과할 수 있게 하여 테이크업 링치차(7) 및 서플라이 링치차(8)의 설치를 용이하게 할뿐만 아니라 서플라이 구동치차(6)의 상·하 치차(6a)(6b)와 테이크업 구동치차(5)의 상·하부위가 서로 치합관계에 있어 종래와 같이 상부나 하부 어느 한쪽에서만 치합되어 있는 것보다 치합상태가 균형있기 때문에 동력전달에 있어서의 언밸런스를 제거하는 효과를 지닌다.The present invention configured as described above has the motor M because the protrusion 1 'of the pulley 1 is coupled to the free space 2' and the locking step 2 ″ of the worm 2 as shown in FIG. At the beginning of the first rotation, the projection 1 'of the pulley 1 rotates once as much as the free space 2' and then is caught by the locking jaw 2 ″ to rotate the worm 2 of the drive unit. When (M) starts for the first time, the motor starts to idle as much as the free space, so it rotates without load, so the motor starts smoothly. This prevents damage to the motor since it does not interfere with the rotation. The take-up ring tooth 7 can pass through the missing groove 6 'by dividing the supply drive gear 6 into the upper and lower teeth 6a and 6b. To facilitate the installation of the take-up ring gear 7 and the supply ring gear 8, as well as the up / down gears 6a and 6b of the supply drive gear 6 and the take-up drive gear 5. Since the upper and lower portions are engaged with each other, the state of balance is more balanced than that of the upper or lower ones as in the related art, thereby removing the unbalance in power transmission.
