Abstract

{목적}{purpose}

레버의 왕복운동을 피동기어의 일방향연속회전운동으로 전환시킬 수 있는 기어구동장치를 제공하기 위한 것이다.So that the reciprocating motion of the lever can be switched to the one-directional continuous rotational motion of the driven gear.

{구성}{Configuration}

레버축에 지지된 레버(1)의 선회단측에 호상공(4)을 천공하고, 이 호상공(4)의 내호면에는 향심 톱니(5)를 형성하고 외호면에는 원심 톱니(6)를 형성함과 동시에 양 톱니(5,6)간에 단치를 두며, 호상공(4)의 양단에 위치한 종점부(7,8)는 무톱니부로 형성하고, 레버운동시 상기 호성공(4)의 폭중심점이 그리는 궤적(10)상의 일점에는 종축기어축(9)을 설치하고 여기에 이동수단(12,13)에 의하여 축방향으로 이동하여 상대측 톱니(6) 또는 (5)로 옮겨가서 잇물림됨과 동시에 종동기어축(9)과의 동기가능하게 종동기어(11)를 축설치한 기어구동장치이다.A circular arc 4 is pierced on the turning end side of the lever 1 supported by the lever shaft and a centering tooth 5 is formed on the inner arc surface of the arc 4 and a centrifugal tooth 6 is formed on the outer surface And the end points 7 and 8 located at both ends of the arc 4 are formed as non-toothed portions. In the lever movement, the width center point of the arc success (4) A longitudinal axis gear shaft 9 is provided at one point on the drawing locus 10 and is moved in the axial direction by the moving means 12 and 13 to be moved to the counter gear teeth 6 or 5, And a driven gear 11 is provided on the shaft so as to be able to synchronize with the gear shaft 9.

Description
