본 고안은 기계식 UHF 튜너에 관련된 것으로서, 보다 상세히는 상기 튜너의 로터측(Rotor Shaft)와 이를 회동시키기 위한 기어(Gear)의 결합이 용이하게 이루어지도록 한 기계식 UHF 튜너의 로터측과 기어의 결합장치에 관한 것이다.The present invention relates to a mechanical UHF tuner, and more specifically, the rotor side of the tuner and the coupling device of the mechanical side of the mechanical UHF tuner to facilitate the coupling of the gear (Gear) for rotating it It is about.

이러한 기술과 관련된 종래의 로터축과 기어 결합장치에 있어서는, 제1도 및 제2도와 같은 구조로 이루어졌다.In the conventional rotor shaft and gear coupling device related to this technique, it has the structure shown in FIG. 1 and FIG.

즉, 복수의 로터플레이트(Rotor Plate)(2)가 부착되어 있는 로터측(Rotor Shaft)(1)과, 육각홈붙이 나사(5)가 삽입되는 홀(4)이 천설된 기어링(Gear Ring)(3), 육각홈붙이나사(5) 및 이 나사(5)를 체결하기 위한 나사 홀(8)과 상기 기어링(3)을 끼워 삽입하기 위한 중앙홀(7)이 천설 된 기어(6)로 구성된다.That is, a gear ring in which a rotor shaft 1 to which a plurality of rotor plates 2 are attached, and a hole 4 into which a hexagonal grooved screw 5 is inserted are installed. (3), a hexagonal grooved screw (5), a screw hole (8) for fastening the screw (5) and a center hole (7) for inserting the gear ring (3) into the gear (6). It is composed.

이러한 종래의 장치를 결합함에 있어서는, 로터측(1)의 단부에 기어링(3)을 압입에 의해 삽입하고 이를 기어(6)의 중앙홀(7)에 삽입한 다음, 기어(6)의 나사홀(8)로 육각홈붙이나사(5)를 체결하여 고정하므로서 결합작업이 완료되는 것이었다.In joining such a conventional device, the gear ring 3 is inserted into the end of the rotor side 1 by pressing and inserted into the center hole 7 of the gear 6, and then the screw hole of the gear 6. The coupling work was completed by fastening and fixing the hexagonal grooved screw 5 with (8).

그러나, 상기와 같은 구조에 있어서는, 로터측(1)에 기어링(3)을 삽입하는 공정과, 로터측(1)에 기어(6)를 삽입하는 공정 및, 상기 로터측(1)에 육각홈붙이나사(5)로 기어(6)를 체결 고정하는 고엉의 3공정으로 이루어지는 것으로서, 작업공정이 복잡하고 조잡하여 생산성 저하시키게 되는 단점이 있는 것이다.However, in the above structure, the step of inserting the gear ring 3 into the rotor side 1, the step of inserting the gear 6 into the rotor side 1, and the hexagonal groove in the rotor side 1 It is made of three steps of the gore for fastening and fixing the gear 6 with the screw 5, there is a disadvantage that the work process is complicated, coarse and reduced productivity.

또한, 로터축(1)에 기어(6)를 육각홈붙이나사(5)로 세팅시, 세팅포인트의 변동이 용이하여 재세팅이 종종 요구되는 등의 번거로운 문제점이 있었던 것이다.In addition, when setting the gear 6 to the rotor shaft 1 with a hexagonal grooved screw 5, there is a troublesome problem such as the change of the setting point is easy and resetting is often required.

본 고안은 상기한 바와 같은 종래의 문제점들을 해소하기 위하여 안출된 것으로서, 그 목적은 로터측의 단부에 너얼링(Knurling)을 형성하므로서 부품수가 줄어들고 결합조립작업이 용이하여 생산성이 향상됨은 물론 원가절감에 기여할 수 있도록 한 기계식 UHF 튜너의 로터측과 기어의 결합장치를 제공하는데 있다.The present invention has been made to solve the above-mentioned problems, the purpose is to form a knurling on the end of the rotor (Knurling) to reduce the number of parts and easy assembly and assembly work to improve productivity as well as cost reduction To provide a coupling mechanism for the rotor side and gears of a mechanical UHF tuner.

이하에서 본 고안을 첨부된 도면에 의거 더욱 상세하게 설명하면 다음과 같다.Hereinafter, the present invention will be described in more detail with reference to the accompanying drawings.

제3도 및 제4도에 도시한 바와같이, 복수의 로터플레이트(2)가 부착된 로터측(1)의 단부에 너얼링부(11)를 형성하고, 기어(6)의 중앙홀(7)을 로터축(1)의 너얼링부(11) 직경보다 약간 작은 직경의 중앙홀(7a)로 되도록 형성된 구성으로 이루어진다.As shown in FIG. 3 and FIG. 4, the knurling part 11 is formed in the edge part of the rotor side 1 to which the some rotor plate 2 was attached, and the center hole 7 of the gear 6 is shown. It consists of a configuration formed so as to be a central hole (7a) of a diameter slightly smaller than the diameter of the knurling portion 11 of the rotor shaft (1).

상기와 같이 구성된 본 고안은, 로터측(1)의 너얼링부(11)를 기어(6)의 중앙홀(7a)에 삽입토록 에어실린더 등을 이용해서 압입 삽입 하므로 결합 조립 작업이 완료된다.The present invention configured as described above is press-fitted using an air cylinder or the like so as to insert the knurling portion 11 of the rotor side 1 into the central hole 7a of the gear 6, thereby completing the coupling assembly operation.

이때, 기어(6)의 중앙홀(7a)로 로터측(1)의 너얼링부(11)에 의해 흠집이 생겨 압입 삽입되는 상태로 결합되므로 견고하게 결합된다.At this time, since the scratches are generated by the knurling portion 11 of the rotor side 1 into the center hole 7a of the gear 6 and are inserted in the press-inserted state, the coupling is firmly performed.

그러므로, 본 고안의 결합 장치는 종래 결합장치의 기어링(3) 및 육각홈붙이나사(5)가 제거되어 부품수가 줄어들고 이로인해 재료비의 절감이 이루어지게 된다.Therefore, in the coupling device of the present invention, the gearing 3 and the hexagonal grooved screw 5 of the conventional coupling device are removed, thereby reducing the number of parts, thereby reducing the material cost.

또, 로터측(1)의 너얼링부(11)와 기어(6)의 중앙홀(7a)이 서로 압입 삽입되는 하나의 공정으로 결합조립 작업이 완료되므로서 작업능률 및 생산성이 향상되고 결과적으로 원가절감이 이뤄지게 된다.In addition, since the assembly and assembly work is completed in a single process in which the knurling portion 11 of the rotor side 1 and the central hole 7a of the gear 6 are press-inserted into each other, the work efficiency and productivity are improved, resulting in cost. Savings will be made.

또, 로터축(1)에 기어(6)를 세팅히 세팅포인트의 변동염려가 없게 되어 재세팅으로 인한 작업공정이 요구되지 않게 되는 등 실용상 유용한 고안인 것이다.In addition, the gear 6 is set on the rotor shaft 1 so that there is no fear of setting point fluctuation, so that a work process due to resetting is not required.
