Abstract

A traction and bending joint for a farm machine using a tractor is provided to minimize the damage of a bending joint when a bending angle is large by letting ends of yokes of both sides have the same angle. A center yoke(11) is installed in the middle of the inside of outer bodies(10,10a) on both sides of a traction and bending joint for a farm machine using a tractor. Yokes(12,12a) on both sides are connected by a cross bearing(13). A power transmission shaft having a spline formed thereon is inserted into insertion holes that form spline on the rear of the yokes on both sides. Springs(21) are installed inside caps(20,20a) between the power transmission shafts and yokes of both sides. A connection rod(31) connecting a pulling rod(30) is attached to the lower part of the outer body of a front yoke with a pin.

본 발명은 트랙터 작업기용 견인 굴절 조인트에 관한 것이다, 좀더 자세하게는 견인 조인트의 굴절시에 센터 요크는 크로스 베어링으로 설치된 양측 요크의 후 방에 설치된 스프링의 탄력에 의하여 동력 전달 축과 스프라인으로 연결되어 있어 양측 요크는 스프라인을 타고 이동되므로 어느 각도에서도 항상 중심으로 센터 요크가 이동되어도 수평을 유지하고 있어 양측 요크의 단부가 항상 등각을 이루고 있어 부하가 균일하게 걸리어 굴절 각을 크게 할 경우에도 굴절 조인트의 파손을 최소화시킬 수 있으며. 또한 전방 요크의 외 동체 하부에는 견인봉을 연결하는 연결 봉을 핀으로 유착하고 있어 굴절 각을 더욱 크게 할 수 있어 각 요크에 무리한 힘이 가해 지지 않아 각 조인트의 파손을 최소화시키게 한 것이다.The present invention relates to a traction articulation joint for a tractor work machine. More specifically, when the traction joint is articulated, the center yoke is connected to the power transmission shaft and the spline by elasticity of a spring installed at the rear of both yokes installed as cross bearings. Both yokes are moved along the spline, so they are always horizontal even when the center yoke is moved to the center at all angles. It can minimize the breakage of the joint. In addition, the lower end of the outer yoke of the front yoke is connected to the connecting rod connecting the rod with a pin, so that the angle of refraction can be increased to minimize the breakage of each joint because excessive force is not applied to each yoke.

종래에는 도 B 에 서와 같이 견인 굴절 조인트는 한쪽 요크(1)는 동력 전달축(2)에 용접하였기 때문에 각도를 조절하기 위하여 조인트를 굴절시키게 되면 양측 요크(1)(1a)의 굴절 각도가 서로 다르기 때문에 고정된 동력 전달 축(2)이 밀어 올리는 힘의 반작용에 의하여 크로스 베어링(3)이 견딜 수 없는 힘의 작용으로 파손되며, 메인축의 베어링에도 무리한 힘이 가해져서 파손이 쉽게 되는 동시에 견인 굴절 조인트와 연결된 유니버설 조인트가 견디지 못하고 파손되는 경우가 허다하여 작업의 지장 및 보수 수리비가 많이들 뿐 아니라 폐기시키는 예가 허다하였다.Conventionally, as shown in FIG. B, the traction articulation joint is welded to one of the yoke (1) to the power transmission shaft (2). Since they are different from each other, the cross bearing 3 is damaged by the action of the force that the fixed power transmission shaft 2 pushes up, and the bearing of the main shaft is excessively applied to the bearing to make the damage easier and towing. Since the universal joint connected to the articulated joint is often unbearable and damaged, it is not only troublesome and expensive to repair, but also a lot of examples of disposing.

본 발명은 종래의 문제점을 최소화하기 위하여 견인 굴절 조인트의 굴절시에 센터 요크는 크로스 베어링으로 설치된 양측 요크의 후방에 설치된 스프링의 탄력에 의하여 동력 전달 축에 형성된 스프라인을 타고 이동되므로 어느 각도에서도 항상 중심으로 센터가 이동되어도 수평을 유지하고 있어 양측 요크의 단부가 항상 등각을 이루고 있어 굴절 각을 크게 할 경우에도 굴절 조인트의 파손을 최소화시킬 수 있으며. 또한 전방 요크의 외부 동체 하부에는 견인봉을 연결하는 연결 봉을 핀으로 유착하고 있어 굴절 각을 더욱 크게 할 수 있어 각 요크에 무리한 힘이 가해 지지 않아 각 조인트의 파손을 최소화시키게 한 것이다.In the present invention, in order to minimize the conventional problems, the center yoke is always moved at any angle since the center yoke is moved along the spline formed on the power transmission shaft by the elasticity of the spring installed at the rear of both yokes installed as cross bearings. Even when the center is moved to the center, the level remains horizontal, so the ends of both yokes are always equiangular, minimizing the breakage of the articulation joint even when the angle of refraction is increased. In addition, the lower part of the outer yoke of the front yoke is connected to the connecting rod connecting the rod with a pin, so that the angle of refraction can be increased to minimize the breakage of each joint because excessive force is not applied to each yoke.

The center yoke 11 is placed in the middle of the outer body 10 and the inner side of the traction articulation joint, and both yokes 12 and 12a are connected with the cross bearings 13. The power transmission shafts 15 and 15a having the splines are inserted into the insertion holes 14 and 14a having the splines behind the yokes 12 and 12a so as to be movable. A spring 21 is provided inside both caps 20 and 20a between the two power transmission shafts 15 and 15a and the yoke 12 and 12a. Power transmission shafts 15 and 15a and both yokes 12 are supported by the elasticity of the springs 21 installed in both caps 20 and 20a at the rear of both yoke 12 and 12a provided with the cross bearing 13. (12a) is connected to the spline so that both yoke (12) (12a) is moved along the spline, so that even if the center yoke (11) is moved to the center at any angle, both sides yoke (12) Since the end of (12a) is always equiangular, the load is uniformly applied and the breakage of the refraction joint can be minimized even when the refraction angle is increased. In addition, the lower end of the outer body 10 of the front yoke 12 is connected to the connecting rod 31 for connecting the traction rod 30 with the pin 32, so that the angle of refraction can be further increased. It is not applied to minimize the breakage of each joint.
