작동상에 있어서, 상기 태양기어(12) 구동력에 의해 유성기어(14)가 회전되어 피니언기어(16)를 구동하면, 피니언기어(16)는 타원형 내접기어(22) 피치원을 따라 치합되어 구동력이 전달된다. 도 4 (a)와 같이 피니언기어(16)가 타원형 내접기어(22)의 어느 일측 절삭이송 기어부(22a)에 치합되면 내접기어조립체(20)가 전진방향으로 직선이송되며, 도 4 (b) 내지 (c)처럼 피니언기어(16)가 어느 일측 터닝이송 기어부(22b)에 도달하면 태양기어(12)를 중심으로 역방향 공전되면서 다른 일측 절삭이송 기어부(22a')에 치합되도록 방향전환됨과 동시에 내접기어조립체(20)가 후진방향으로 직선이송되며, 도 4 (d)와 같이 피니언기어(16)가 다른 일측 터닝기어부(22b')에 도달하면 태양기어(12)를 중심으로 정방향 공전되면서 상기 도 4 (a)의 반대측 절삭이송 기어부(22a)에 다시 치합되도록 방향전환되는 작동을 반복 수행하면서 내접기어조립체(20)가 전, 후 직선 왕복이송되면서 톱질 절삭력이 발생된다.In operation, when the planetary gear 14 is rotated by the driving force of the sun gear 12 to drive the pinion gear 16, the pinion gear 16 is meshed along the pitch circle of the elliptical internal gear 22 to drive power. This is delivered. As shown in Fig. 4 (a), when the pinion gear 16 is engaged with any one side of the cutting gear 22a of the elliptical inner gear 22, the inner gear assembly 20 is linearly transferred in the forward direction, and Fig. 4 (b) ) To (c), when the pinion gear 16 reaches any one side turning feed gear 22b, it is reversed around the sun gear 12 and is reversed to be engaged with the other one side cutting feed gear 22a'. At the same time, the inward gear assembly 20 is linearly transferred in the reverse direction, and when the pinion gear 16 reaches the other side of the turning gear portion 22b' as shown in FIG. 4(d), the forward direction is centered around the sun gear 12. While rotating, the internal gear assembly 20 is linearly reciprocated forward and backward while repeating the operation of changing the direction to be meshed again with the cutting feed gear portion 22a on the opposite side of FIG. 4(a), thereby generating sawing force.

이처럼 타원형 내접기어(22) 피치원을 따라 치합되는 피니언기어(16)에 의해 동력원의 일방향 회전력이 직선 왕복이송력으로 전환되어 톱날 전, 후 절삭력이 일정한 속도로 출력되어 톱질 작업이 안정적으로 수행되고, 특히 구성부품의 간소화와 더불어 경량 콤팩트한 구조에서 톱날 전, 후 절삭 행정거리가 확장되는 이점이 있다.In this way, the unidirectional rotational force of the power source is converted into a linear reciprocating transfer force by the pinion gear 16 meshed along the pitch circle of the elliptical internal gear 22, so that the cutting force before and after the saw blade is output at a constant speed and the sawing operation is performed stably. In particular, in addition to the simplification of components, the cutting stroke distance before and after the saw blade is extended in a lightweight and compact structure.

한편, 상기 하우징(1) 전방에는 도 1과 같이 고리형 톱날 가이드가 구비되고, 톱날 가이드는 톱납 선단부를 수용한 상태로 안내하는 가이드홈이 형성되며, 고리형 톱날 가이드의 고리부에 피절삭물을 거는 형태로 톱을 설치하여 큰 힘을 들이지 않고 고소 작업을 수행하게 된다.On the other hand, in the front of the housing (1) is provided with a ring-shaped saw blade guide as shown in Figure 1, the saw blade guide is formed with a guide groove for guiding the state of receiving the top end of the saw blade, the workpiece in the ring portion of the ring-shaped saw blade guide By installing the saw in the form of hanging, the aerial work is carried out without great effort.
