본 고안은 회전동력을 전달하면서 축방향으로의 이동을 가능케하는 길이가변 연결축에 관한 것이다.The present invention relates to a variable length connecting shaft that enables the movement in the axial direction while transmitting the rotational power.
일반적으로 회전동력을 전달하면서 축방향으로 이동하여 구동축과 피동축간의 동력을 전달하는 데에는 스플라인 축이 사용되어진다. 그러나 이와 같은 스플라인축 방식의 동력 전달 장치는 스플라인축의 길이가 한정되는 관계로 구동축과 피동축간의 거리가 스플라인 축의 길이보다 길때에는 동력전달에 어려움이 있다. 또한, 스플라인축은 자형과 웅형이 1조가 되는 구조적인 특성으로 제작에 어려움이 수반되며 제작비가 많이 요구되는 등의 결점이 있다.In general, a spline shaft is used to transfer the power between the driving shaft and the driven shaft by moving in the axial direction while transmitting rotational power. However, such a spline shaft power transmission device has a difficulty in transmitting power when the distance between the drive shaft and the driven shaft is longer than the length of the spline shaft because the length of the spline shaft is limited. In addition, the spline shaft is a structural feature that is a pair of male and male shape is accompanied by difficulties in manufacturing and requires a lot of manufacturing costs.
본 고안은 상기한 스플라인축 방식의 동력전달 장치에 내재되어 있는 제반문제점을 해소하여 제작이 용이하고 구동축과 피동축간의 거리에 관계없이 길이가변을 하여 동력을 전달할수 있는 길이 가변 연결축을 제공하고자 하는 것이다.The present invention is to solve the problems inherent in the power transmission device of the spline shaft type is easy to manufacture and to provide a variable length connecting shaft that can transmit power by varying the length regardless of the distance between the drive shaft and the driven shaft will be.
이와 같은 본 고안의 목적을 달성할 수 있는 특징적인 구성으로는 "" 형상의 단면을 갖는 축을 순차적으로 내삽시켜 양끝단에 커플링으로 구동축과 피동축을 연결토록하는 구성인바, 각 축의 형상은 회전시 슬립현상을 방지하기 위하여 다각형상을 갖도록 하는 것이다.Such a characteristic configuration that can achieve the object of the present invention " "It is a configuration to connect the driving shaft and the driven shaft by coupling to both ends by sequentially interpolating the shaft having a cross-sectional shape, the shape of each shaft is to have a polygonal shape to prevent slip phenomenon during rotation.
본 고안의 구성을 첨부된 도면에 의하여 좀 더 상세히 기술하면 다음과 같다.The configuration of the present invention will be described in more detail with reference to the accompanying drawings.
제1도 및 제2도에 도시한 바와 같이, 커플링(1)의 내측 중공부에는 단면이 대략 "" 형상의 연결축(3)이 헐겁게 끼워맞춤되고, 이 연결축(3)의 내측에는 또다른 연결축(2)이 헐겁게 끼어맞춤된다. 전기한 연결축(2)이 일단은 걸림턱(4)가 형성되고, 타단은 커플링(5)에 압입되어 핀(6)으로 고정되며, 그 외주면의 중간부위는 다각형상을 이룬다. 커플링(1)의 일측 내주연에는 멈춤링(7)이 설치되며, 타측 내주연에는 다각형상을 이루는 내향플랜지(8)이 형성된다.As shown in Figs. 1 and 2, the inner hollow portion of the coupling 1 has a cross section of approximately " The connecting shaft 3 of the "-shape is loosely fitted, and another connecting shaft 2 is loosely fitted inside this connecting shaft 3. ) Is formed, and the other end is press-fitted to the coupling 5 and fixed with a pin 6. The middle portion of the outer peripheral surface thereof forms a polygonal shape.A stop ring 7 is formed at one inner circumference of the coupling 1. It is installed, the inward flange 8 forming a polygonal shape on the other inner peripheral edge is formed.
또한, 연결축(3)의 일측에는 외향플랜지(9)가, 타측에는 다각형상을 이루는 내향플랜지(10)이 각각 형성된다. 그리고, 이 물질의 유입을 방지하는 부츠(11)이 커플링(1)과 (5)의 외주면에 체결밸드(12)로 클램프되는 구성이다.Further, an outward flange 9 is formed at one side of the connecting shaft 3 and an inward flange 10 having a polygonal shape at the other side thereof. In addition, the boot 11 for preventing the inflow of the substance is configured to be clamped by the fastening belt 12 on the outer peripheral surface of the coupling (1) and (5).
미설명부호 13은 구동축을, 14는 피동축을 나타낸다.Reference numeral 13 denotes a drive shaft, and 14 denotes a driven shaft.
이와 같이 구성되는 본 고안의 작용효과를 기술하면 다음과 같다.Referring to the effect of the present invention is configured as described as follows.
구동축(13)과 피동축(14)가 일정한 거리를 두고 설치되는데 있어 동력전달을 필요로 할때에는 커플링(1)에 구동축(13)을, 커플링(5)에는 피동축(14)을 각각 연결한다. 그리고, 구동축(13)과 피동축(14)가 일정의 각도를 이루며 설치되는데 있어서는 통상의 유니버샬조인트를 연결할 수도 있다.When the drive shaft 13 and the driven shaft 14 are installed at a predetermined distance and need to transmit power, the drive shaft 13 is connected to the coupling 1 and the driven shaft 14 is connected to the coupling 5, respectively. Connect. In addition, when the driving shaft 13 and the driven shaft 14 are installed at a predetermined angle, a general universal joint may be connected.
이와 같이 구동축(13)과 피동축(14) 사이에 본 고안의 길이가 변 연결축이 연결되어 있는 상태에서는 두축간의 거리가 축방향으로 가변됨에 제2도의 화살표 A,B 방향으로 신축 조절된다. 즉, 두축간의 거리가 가까워질때에는 연결축(2)가 피동축(14)에 연결된 커플링(5)에 압입되어 있음에 기인하여 피동축(14)가 좌측으로 이동하면서 연결축(2)를 밀어 A 방향으로 이동시키고, 나아가서는 연결축(3)도 A방향으로 이동시켜 두축의 거리가 좁아짐에 대응된다.Thus, in the state where the length of the present invention is connected between the drive shaft 13 and the driven shaft 14, the distance between the two axes is changed in the axial direction, and thus the expansion and contraction is made in the directions of arrows A and B of FIG. . That is, when the distance between the two axes is closer, the connecting shaft 2 is pushed into the coupling 5 connected to the driven shaft 14, so that the driven shaft 14 moves to the left while the connecting shaft 2 It is pushed to move in the A direction, and furthermore, the connecting shaft 3 also moves in the A direction, corresponding to the narrowing of the distance between the two axes.
반대로 두축간의 거리가 멀어질때에는 연결축(2)가 피동축(14)에 연결된 커플링(5)에 핀(6)으로 고정되어 있음에 기인하여 피동축(14)가 우측으로 이동하면서 연결축(2)를 당기어 B방향으로 신장시킨다.On the contrary, when the distance between the two axes increases, the connecting shaft 2 is fixed to the coupling 5 connected to the driven shaft 14 with the pin 6, and the driven shaft 14 moves to the right. Pull the shaft (2) to extend it in the B direction.
좀더 상세하게는, 피동축(14)가 B방향으로 이동함에 연결축(2)가 동일방향으로 이동하면서 걸림턱(4)가 내향플랜지(10)에 걸리어 연결축(3)도 같이 이동시키게 되는 것이다.More specifically, as the driven shaft 14 moves in the B direction, the connecting shaft 2 moves in the same direction, so that the locking jaw 4 is caught by the inward flange 10 to move the connecting shaft 3 together. Will be.
이와 같이 축방향으로의 이동이 각축간의 미끄럼 작용으로 이루어지는데 있어 회전력의 전달은 내향플랜지(8)의 내주연부가 다각 형상을 이룸에 동일형상의 연결축(3)이 유삽되고, 내향플랜지(10)의 내주연부가 또한, 다각형상을 이룸에 동일형상의 연결축(2)가 유삽되어, 이 연결축(2)의 밀단이 피동축(14)와 연결되는 커플링(5)에 핀(6)으로 고정되어 있으므로 두축간의 회전력 전달은 이루어지게 된다.As described above, the rotational force is transmitted by the sliding action between the respective axes, so that the inner shaft of the inward flange 8 has a polygonal shape, and the connecting shaft 3 of the same shape is inserted into the inward flange 10. The inner circumferential edge of the) also forms a polygonal shape, and a connecting shaft (2) of the same shape is inserted so that the pin (6) of the coupling (5) is connected to the driven shaft (14). Since it is fixed with), the rotational force transmission between the two axes is made.
이때 부츠(11)은 각축간의 미끄럼작용에 방해되는 이물질의 유입을 방지하기 위하여 커플링(1)과 (5)에 체결밴드(12)로 클램프된 것이다.At this time, the boots 11 are clamped by the coupling band 12 to the couplings (1) and (5) in order to prevent the inflow of foreign matters that interfere with the sliding action between the respective axes.
상기한 바와 같이 본 고안에 의한 길이 가변 연결축은 회전동력을 전달하면서 축방향으로의 이동을 가능케할 뿐 아니라 종래의 스플라인 축 연결방식에서 한정되던 두축간의 거리에 관계없이 본 고안에 의한 연결축 방식은 연결축을 다단으로 하여 두축간의 거리에 대응케 할 수 있다.As described above, the variable length connecting shaft according to the present invention not only enables movement in the axial direction while transmitting rotational power, but also the connecting shaft method according to the present invention regardless of the distance between two axes, which is limited in the conventional spline shaft connecting method. It is possible to correspond to the distance between two axes by making the connecting axis multi-stage.
또한, 본 고안의 연결축은 제작이 용이하여 제작비의 절감을 기할수 있으며 기계식 사통장비 및 각종변속기축 등에 사용할 수 있는 매우 유용한 고안인 것이다.In addition, the connection shaft of the present invention is easy to manufacture and can reduce the production cost is a very useful design that can be used for mechanical communication equipment and various transmission shafts.
