상기 원통 구름부(a)는 제2, 3도에 도시된 바와 같이, 제1 요크(3)와 일체로 형성되며 내측은 관통되어 원환형으로 구성되는 외륜부(9)와, 이 외륜부(9)의 내측에 구름부재(11)를 매체로 하여 외륜부(9)와는 독립하여 회전가능하게 장착되는 내륜부(13)를 포함한다.As shown in FIGS. 2 and 3, the cylindrical cloud portion (a) is formed integrally with the first yoke (3) and has an outer ring portion (9) formed in an annular shape through the inner side thereof, and the outer ring portion ( An inner ring portion 13 is rotatably mounted independently of the outer ring portion 9 using the rolling member 11 as a medium inside the 9).
이 내륜부(13) 내측 중공부에는 십자축(b)의 제1 요크 회전부재(15)가 제1 요크(3)에 수직한 방향이고, 내·외륜부(9,13)의 지름방향으로 제공되어 내륜부(13)의 양측에 고정·장착된다.In the inner hollow portion of the inner ring portion 13, the first yoke rotating member 15 of the cross shaft b is perpendicular to the first yoke 3, and in the radial direction of the inner and outer ring portions 9, 13; It is provided and fixed and mounted at both sides of the inner ring part 13.
또한 제1 요크 회전부재(15)의 일측은 내륜부(13)의 일측에 형성된 고정부재(17)와 결합되어 내륜부(13)와 함께 회전되도록 고정·장착된다.In addition, one side of the first yoke rotating member 15 is fixed and mounted to be coupled to the fixing member 17 formed on one side of the inner ring portion 13 so as to rotate together with the inner ring portion 13.
이와 같이 내륜부(13)에 고정된 제l 요크 회전부재(15)의 중앙부 외측에는As such, the outer side of the central portion of the first yoke rotating member 15 fixed to the inner ring portion 13
제2 요크(7)와 체결 볼트(19)로 결합된 십자축(b)의 제2 요크 회전부재(21)가 구름부재(23)를 매체로 하여 장착된다. 이 구름부재(23)는 부싱(25)에 의하여 지지된다.The second yoke rotating member 21 of the cross shaft b coupled to the second yoke 7 and the fastening bolt 19 is mounted using the rolling member 23 as a medium. The rolling member 23 is supported by the bushing 25.
상술한 바와 같이 구성된 유니버셜 조인트 구조에 있어서, 입력축(l)에 결합된 제1 요크(3)로 동력이 전달되면, 회전방향 전환수단이 수시로 변화되는 입력축(1)과 출력축(5)의 교차각을 조절시켜 제2 요크(7)로 전달한다.In the universal joint structure configured as described above, when power is transmitted to the first yoke 3 coupled to the input shaft 1, the angle of intersection of the input shaft 1 and the output shaft 5, in which the rotation direction switching means changes from time to time, To be delivered to the second yoke (7).
즉, 출력축(5)에 장착된 제2 요크(7)에 체결된 십자축(b)의 제2 요크 회전부재(21)가 구름부재(23)의 지지를 받으며 십자축(b)의 제l 요크 회전부재(l5)의 외주를 회전하게 된다.That is, the second yoke rotating member 21 of the cross shaft b that is fastened to the second yoke 7 mounted to the output shaft 5 receives the support of the rolling member 23 and is the first of the cross shaft b. The outer circumference of the yoke rotating member l5 is rotated.
이와 같이 제2 요크 회전부재(2l)가 제l 요크 회전부재(15)의 외주를 회전하면서 제1 요크 회전부재(15)에 내륜부(3)의 회전방향으로 가해진 작용력에 의하여, 제l 요크 회전부재(15)를 고정한 원통 구름부(a)의 내륜부(13)가 구름부재(11)의 지지를 받으면서 외륜부(9)의 내주를 회전 하게된다.In this way, the second yoke rotating member 2l rotates the outer circumference of the first yoke rotating member 15, and according to the action force applied to the first yoke rotating member 15 in the rotational direction of the inner ring part 3, the first yoke is rotated. The inner ring portion 13 of the cylindrical rolling portion (a) fixing the rotating member 15 is rotated by the inner circumference of the outer ring portion (9) while being supported by the rolling member (11).
이와 갈이 외륜부(9)에 구름부재(11)를 매체로 장착된 내륜부(13)와 이 내륜부(13)에 고정·장착된 제1 요크 회전부재(5)에 구름부재(25)를 매체로 장착된 제2 요크 회전부재(21)가 상호 회전되므로, 입력축(l)의 회전력을 출력축(5)으로 전달할 수 있도록 상기 제l 요크(3)와 제2 요크(7)의 교차각이 조절된다.The rolling member 25 is mounted on the inner ring portion 13 on which the rolling member 11 is mounted as a medium on the outer ring portion 9 and the first yoke rotating member 5 fixed and mounted on the inner ring portion 13. Since the second yoke rotating member 21 mounted as a medium rotates with each other, the crossing angle between the first yoke 3 and the second yoke 7 can transmit the rotational force of the input shaft l to the output shaft 5. This is regulated.
상술한 바와 같이 본 고안에 따른 유니버셜 조인트 구조는 외륜부와 내륜부의 결합부와, 제l,2 요크 회전부재의 결합부에만 구름부재를 사용함으로서, 제작원가를 절감시키고, 제작 공법을 변경시켜 가공방법을 단순화시켰다.As described above, the universal joint structure according to the present invention uses a rolling member only at the coupling portion of the outer ring portion and the inner ring portion and the coupling portion of the first and second yoke rotating members, thereby reducing manufacturing cost and changing the manufacturing method. The method was simplified.
