본 고안은 드로우 타입 데이터 메모리용(DRAW TYPE DATA MEMORY)의 미니 디스크 트레이(TRAY)커버 구동기어에 사용되는 더블기어에 관한 것이다.The present invention relates to a double gear used in a mini disk tray (TRAY) cover drive gear for the draw type data memory (DRAW TYPE DATA MEMORY).
종래의 더블기어는 예시도면 제 1 도에 도시된 바와같이, 상측기어(1)의 하부에 결합요홉(2)과 걸림턱(3)이 형성되고, 하측기어(4)의 상면에는 결합돌환부(5)와 걸림요홈(6)이 형성되며 걸림요홈(6)과 걸림턱(3)사이에는 실린더형 판넬스프링(7, PANEL SPRING)이 대칭형으로 결합된 구조로 되어 있었다.In the conventional double gear, as shown in FIG. 1, the coupling yog 2 and the locking jaw 3 are formed at the lower side of the upper gear 1, and the engaging projection is formed on the upper surface of the lower gear 4. (5) and the locking groove 6 is formed, and the cylindrical panel spring (7, PANEL SPRING) was symmetrically coupled between the locking groove (6) and the locking jaw (3).
판넬스프링(7)은 기어와 인접한 기어가 맞물린 상태에서 정지 또는 회전명령을 받았을때 미세한 여유를 부여함으로서 완충역할을 하며 기구적인 미세한 보상을 하여 기어를 보호하고 정확한 동작이 이루어질 수 있도록 하는 것이다.The panel spring 7 provides a buffer by providing a small margin when a stop or rotation command is received while the gear and the adjacent gear are engaged, and protects the gear by performing a mechanical fine compensation to enable accurate operation.
그러나 상기와 같은 구조를 갖는 종래의 더블기어는 완충용 스프링 즉, 판넬스프링이 제조 및 취급하기에 너무 작기 때문에 조립하는데 시간이 걸리고 제조하기 까다로운 결점이 있었다.However, the conventional double gear having such a structure takes time to assemble and is difficult to manufacture because the shock absorbing spring, that is, the panel spring is too small to manufacture and handle.
본 고안은 상기와 같은 결점을 해결하기 위하여 하측기어의 상면에 돌설된 결합 돌환부의 양단에 고리형 스프링을 일체로 형성시킴으로서 제조 및 조립이 간편한 더블기어를 제공함에 목적이 있다.The object of the present invention is to provide a double gear that is easy to manufacture and assemble by integrally forming an annular spring on both ends of the engaging projection projecting on the upper surface of the lower gear to solve the above drawbacks.
본 고안을 첨부된 예시도면과 함께 상세히 설명하면 다음과 같다.The present invention will be described in detail with reference to the accompanying drawings.
본 고안은 상측기어(1)와 하면에 결합요홈(2)과 걸림턱(3)이 형성되고 하측기어(4)의 상면에 결합돌환부(5)와 걸림요홈(6)이 형성된 통상의 더블기어에 있어서, 결함 돌환부(5)의 양단에 결합돌환부(5)와 일체로 된 환형탄성부(8)를 형성한 구조로 되어있다.In the present invention, the upper gear 1 and the lower surface of the coupling groove 2 and the locking jaw (3) is formed on the upper surface of the lower gear 4, the coupling double portion 5 and the locking groove (6) is usually formed The gear has a structure in which annular elastic portions 8 which are integral with the engaging projection 5 are formed at both ends of the defective projection 5.
본 고안의 사용상태 예시도를 보여주는 예시도면 제 4 도중 미설명 부호 9는 트레이 하면, 10은 무빙렉, 11은 스크류, 12는 트레이 커버랙, 13은 하측기어(4)와 무빙랙(10)의 기어 연결부이다.Figure 4 shows an exemplary view of the use state of the present invention, while the fourth reference numeral 9 is the bottom of the tray, 10 is a moving rack, 11 is a screw, 12 is a tray cover rack, 13 is a lower gear (4) and a moving rack (10) Gear connection.
본 고안은 상측기어(1)와 하측기어(4)가 결합된 상태에서는 결합돌환부(5)의 양단부에 형성된 환형탄성부(8)가 걸림턱(3)의 양쪽에 접하게되므로 기어연결부(13)의 과부하를 방지하게 되는 것이다. 즉, 기어연결부(13)에 미세한 간극이 생기면 환형탄성부(8)에 의해서 정상적인 결합상태로 보정되는 것이다.According to the present invention, in the state where the upper gear 1 and the lower gear 4 are coupled, the annular elastic portion 8 formed at both ends of the engaging projection 5 is in contact with both sides of the locking step 3, so that the gear connecting portion 13 ) Will prevent overload. That is, when a minute gap occurs in the gear connecting portion 13, the annular elastic portion 8 is corrected to a normal engagement state.
본 고안은 판넬 스프링 역할을 할 수 있는 환형탄성부(8)가 결합돌환부(5)의 양단에 일체로 형성되어 있으므로 제조시에 스톱퍼 정밀도에 대한 공차가 확대되고, 조립이 간편하며 결합돌환부(5)가 완충역할을 하여 미세한 움직임을 보상하므로 기어연결부(13)에 발생하는 간극을 없애줄 뿐만 아니라, 기어를 보호하여 주는 효과가 있다.In the present invention, since the annular elastic portion 8, which may serve as a panel spring, is integrally formed at both ends of the coupling protrusion 5, the tolerance for the stopper precision is increased during manufacturing, and the assembly is easy and the coupling protrusion is (5) serves as a buffer to compensate for the minute movement, so as to eliminate the gap generated in the gear connecting portion 13, there is an effect that protects the gear.
