본 고안은 텔레비전이나 라디오의 튜어너 등 전기 기기의 비교적 가벼운 하중으로, 작동하는 회전축의 축지(軸止) 구조에 관한 것으로 그 목적하는 바는 구조가 간단하고, 회전축에 축 고정을 위한 압압스프링에 의한 부하가 걸리지 않는 한편 회전축의 축 방향에 대한 위치결정 설계의 자유도가 큰 축지구조(軸止構造)를 값싸게 제공함에 있다.The present invention relates to a shaft structure of a rotating shaft that operates with a relatively light load of an electric device such as a tuner of a television or a radio. The purpose of the present invention is to provide a pressurized spring for fastening the shaft to the rotating shaft. The present invention provides an inexpensive bearing structure with a large degree of freedom in positioning design with respect to the axial direction of the rotating shaft without load.

종래의 텔레비전 튜어너 등에 있어서의 회전축이 축지구조로서는, 제5도 및 제6도에 나타낸 바와 같이 틀체(11)에 축 안내홈(12)과 압압스프링(15)을 설치하기 위한 구멍(16), (17)을 설치하고 또 회전축(13)에는 축지홈(14)을 설치하여 이 축지홈(14)을 틀체911)의 축 안내홈(12)에 삽입한 후 회전축(13)을 압압스프링(15)으로서 압압하여 회전축(13)의 유지를 하고 있었으나 그 경우 회전축의 이완을 방지하기 위해서는 압압스프링(15)의 압압력을 증대시킬 필요가 있으며 그 때문에 마찰저항도 증대하고 또 틀체(11)의 회전축(13)과의 접촉부 및 축지홈(14)의 마모가 현저하게 되어 성능 및 수명적으로 문제를 발생하며, 특히 텔레비전 튜어너의 주축에 적용시킨 경우 타진 노이즈(打振 noise)에 의한 화면의 안정성을 유지하기 위해서는 유지력을 충분하게 할 필요가 있는 한편 유지력 확보의 결과에 따른 저항의 증대는 주축회전시의 토오크(torque), 절도감각, 복귀력 등에 악영향을 미치게 되어 전체를 양호하게 하는 것은 매우 곤란하여 실용시에는 시행착오에 의한 보정을 거듭함으로써 허용조건 내에 알맞는 방법을 결정하는 것이 일반적이었다. 또한 회전축의 스러스트(thrust) 방향의 안정도는 압압스프링과 축지홈과의 계합만으로 유지되기 때문에 정밀도 및 수명적으로 한계가 있었다.As a rotating shaft in a conventional television tuner or the like, the hole 16 for installing the shaft guide groove 12 and the pressing spring 15 in the frame 11 is shown in FIGS. 5 and 6. And (17), and a shaft groove (14) is installed in the rotary shaft (13), and the shaft groove (14) is inserted into the shaft guide groove (12) of the frame body 911, and then the rotary shaft (13) is pressed into the spring ( 15) was pressed to hold the rotary shaft 13, but in this case, it is necessary to increase the pressing force of the pressing spring 15 in order to prevent the rotation of the rotating shaft from being loosened. Abrasion of the contact portion and the bearing groove 14 with the rotating shaft 13 becomes remarkable, causing problems in terms of performance and lifespan, and especially when applied to the main shaft of the television tuner, In order to maintain stability, it is necessary to have sufficient holding force. Increasing resistance as a result of securing the holding force adversely affects torque, theft sensation, and return force during spindle rotation, and it is very difficult to improve the whole, and in practice, the correction by trial and error is repeated. It was common to decide how to fit within the acceptable conditions. In addition, since the stability of the thrust direction of the rotating shaft is maintained only by the engagement between the pressing spring and the bearing groove, there is a limit in accuracy and life.

본 고안은 축지홈의 폭과 동일 폭의 절결부를 설치 축수를 사용하는 것에 의해 상기의 결점을 해소시킨 것으로 그 실시예를 제1도 내지 제4도에 의거 상세히 설명하면 다음과 같다.The present invention solves the above-mentioned drawbacks by using the installation shaft number of the cutout portion having the same width as the groove groove, and the embodiment will be described in detail with reference to FIGS. 1 to 4 as follows.

1은 틀체이고 이 틀체(1)에는 축 안내홈(2)과 압압스프링(5)을 취부하기 위한 구멍(6), (7)을 설치하고 있다. 3은 회전축으로서 이 회전축(3)에는 축 안내홈(2)에 계합하기 위한 축지홈(4)이 설치되어 있다. 8은 축수로서 상기 회전축(3)의 축지홈(4)과 동일폭의 절결부(9)를 설치하였다. 그리고 상기 틀체(1)에 회전축(3)을 유지하는 데는 회전축(3)에 축수(8)를 삽입하고 축지홈(4)과 절결부(9)를 일치시킨 후 틀체(1)의 축 안내홈(2)에 양자를 계합하여 압압스프링(5)으로 고정한다.1 is a frame, and the frame 1 is provided with holes 6 and 7 for mounting the shaft guide groove 2 and the pressing spring 5. 3 is a rotary shaft, and the rotary shaft 3 is provided with a bearing groove 4 for engaging the shaft guide groove 2. 8 is the number of shafts, and the notch 9 of the same width | variety as the bearing groove 4 of the said rotating shaft 3 was provided. In order to maintain the rotating shaft 3 on the frame 1, the shaft 8 is inserted into the rotating shaft 3, and the shaft groove 4 and the notch 9 are aligned, and then the shaft guide groove of the frame 1 is formed. The two are engaged with (2) and fixed with a pressing spring (5).

본 고안의 구조는 상술한 바와 같으므로 압압스프링(5)에 의한 부하는 축수(8)에 걸리고 회전축(3)에는 직접적으로 부하가 가해지지 않으므로 회전축(3)은 틀체(1)와의 사이에 커다란 마찰저항을 일으키지 않으며 회전이 원활하게 되고 회전축(3)의 수명이 길게 되며 채널절환시의 토오크, 절도감각, 복귀력 등도 양호하게 되는 한편 접점 등을 갖춘 디스크를 장치한 회전축의 축 방향 위치 결정을 간단하고 정확하게 행할 수 있는 등의 작용효과를 갖는다.Since the structure of the present invention is as described above, the load by the pressing spring 5 is applied to the shaft number 8, and since the load is not directly applied to the rotating shaft 3, the rotating shaft 3 is large between the frame 1 and the frame 1. No frictional resistance, smooth rotation, long life of the rotating shaft (3), good torque, theft and return force during channel switching, and axial positioning of the rotating shaft with disks with contacts. The effect is simple and accurate.
