제6도는 종래 튜너의 종동치차를 나타낸 사시도.6 is a perspective view showing a driven gear of a conventional tuner.

본 고안은 UHF 튜너의 구동장치에 있어서, 로우터축에 장착되는 종동치차를 탄성의 합성수지제로 형성하되 치폭을 치차의 림의 두께보다 양쪽으로 연장시킨 상태의 헬리컬 치차로 구성함으로서 주축의 평치차와 치합되어 회전할때 양치차간에 백래쉬 (backlash : 서로 치합된 구동치차와 종동치차의 치 사이에 생기는 미세한 틈)가 발생되지 않도록 하여 튜너의 튜닝(Tunning) 작업이 항상 정확하게 이루어지도록 고안한 것이다.The present invention is a drive device of the UHF tuner, in which the driven gear mounted on the rotor shaft is made of elastic synthetic resin, but is composed of a helical gear with teeth extending both sides than the thickness of the gear rim. It is designed to make the tuning work of the tuner always accurate by preventing backlash between the teeth of the teeth and the teeth of the driven gear when the teeth are rotated.

종래 튜너의 구동장치를 보면 주축의 평치차와 로우터축의 평치차간에 발생하는 백래쉬를 방지하고 정확한 튜닝조작을 하기 위하여 로우터축의 종동치차를 두개의 평치차를 중첩한 복치차로 구성하여 이들을 첨부 도면 제6도에 도시한 바와 같이 강력한 스프링으로 탄력을 갖게 하면서 각 치차의 치가 서로 비스듬히 위치하도록 하므로서 주축의 평치차와의 백래쉬를 최소한으로 줄여 왔으나, 이는 부품의 추가 및 조립작업의 어려움 등으로 제작상 불편한 점이 많았고, 로우축을 정밀하게 작동시켜 정확한 튜닝조작을 얻기에는 매우 미흡한 상태였다.In the conventional tuner driving device, the driven gear of the rotor shaft is composed of a geared gear which overlaps two flat gears in order to prevent backlash between the flat shaft of the main shaft and the flat shaft of the rotor shaft and to perform accurate tuning. As shown in 6 degrees, the teeth of each gear are positioned at an angle to each other while having elasticity with a strong spring, thereby reducing backlash with the flat car of the main shaft to a minimum, but this is inconvenient in production due to difficulty in adding parts and assembling work. There were many points, and it was very insufficient to operate the low shaft precisely to obtain accurate tuning operation.

본 고안은 종래 이러한 결점을 보완코자 안출한 것으로, 이를 첨부도면에 의거하여 상세히 설명하면 다음과 같다.The present invention has been devised to compensate for these drawbacks in the prior art, which will be described in detail based on the accompanying drawings.

즉, 튜너본체(1)내에 수개의 바리콘(2)을 축설하고 일단에 종동치차를 장착한 로우터축(3)을 장착하고, 본체(1)의 일측에는 전술한 종동치차와 치합하는 구동치차를 축설한 주축(5)을 장착한 통상의 UHF 튜너의 구동장치에 있어서, 로우터축(3) 일단에 장착되어 주축(5)의 구동치차(4)와 치합하는 종동치차(6)를 탄성의 합성수지재 헬리컬기어로 형성하되, 치(7)의 치폭을 림(8)의 양쪽으로 연장형성하여 탄성의 치폭단( 7a)(7b)을 구성한 튜너의 구동장치이다.That is, the rotor shaft 3 which has several varicons 2 built into the tuner main body 1, and the driven gear is attached to one end, and the drive gear which engages with the above-mentioned driven gear on one side of the main body 1 is mounted. In the drive device of a conventional UHF tuner equipped with a built-in main shaft (5), an elastic synthetic resin is formed in a driven gear (6) mounted on one end of the rotor shaft (3) and engaged with a drive gear (4) of the main shaft (5). The helical gear is formed again, and the tooth width of the tooth 7 extends to both sides of the rim 8 so as to constitute an elastic tooth width 7a, 7b.

미설명부호 4a는 구동치차의 치, 4b는 치홈, 9는 종래에 사용된 복치차, 10은 스프링이다.Reference numeral 4a denotes a tooth of the drive gear, 4b a tooth groove, 9 a conventionally used toothed gear, and 10 a spring.

이와 같이 구성된 본 고안은 합성수지재 헬리컬치차로 형성된 종동치차(3)와 평치차로 형성된 구동치차(4)가 서로 치합된 상태를 보면 제4도와 제5도에 나타난 바와 같이, 구동치차(4)의 치홈(4b)에 종동치차(6)의 치(7)가 치합될 때 림(8)의 양쪽으로 연장된 치폭단(7a)(7b)이 서로 반대방향(제5도의 화살표방향)으로 변형되면서 치합되므로 동치폭단(7a)(7b)의 탄발력에 의하여 종동치차(6)와 고동치차(4)간의 치합상태가 긴밀하게 되어 구동치차(4)가 어느 방향으로 회전되어도 즉. 한방향으로 회전하다가 갑자기 다른 방향으로 회전하더라도 백래쉬가 전혀 발생하지 않으며, 본 고안과 같이 종동치차(6)를 합성수지재 헬리컬치차로 형성하면 종래의 복치차에 비하여 제작이 매우 용이하고 조립과정이 간단 용이할뿐 아니라 저렴한 가격으로 제공받을 수 있는 것등의 특징을 갖는 것이다.According to the present invention configured as described above, the driven gear 3 formed of the synthetic resin helical gear and the driving gear 4 formed of the flat gear are engaged with each other, as shown in FIGS. 4 and 5, When the teeth 7 of the driven gear 6 are engaged with the tooth groove 4b, the tooth width ends 7a and 7b extending to both sides of the rim 8 are deformed in opposite directions (arrow direction in Fig. 5). Because of the engagement, the engagement state between the driven gear 6 and the driven gear 4 becomes tight due to the repulsive force of the equivalent tooth end 7a, 7b, so that the driving gear 4 is rotated in any direction. When rotating in one direction and suddenly rotating in the other direction, no backlash occurs. When the driven gear 6 is formed of a synthetic resin helical gear as in the present design, it is very easy to manufacture and easy to assemble as compared with the conventional gear. In addition to being able to be provided at a low price.
