본 발명은 유니버셜 조인트에 관한 것으로서, 보다 상세하게는 요크와 베어링 케이스 사이의 슬립을 방지하여 동력 전달시 소음 및 진동을 방지할 수 유니버셜 조인트 구조에 관한 것이다.The present invention relates to a universal joint, and more particularly to a universal joint structure that can prevent the slip between the yoke and the bearing case to prevent noise and vibration during power transmission.

일반적으로 유니셜 조인트는 2 개의 축이 어느 각도를 이루어 교차할 때 자유로이 동력을 전달하기 위한 장치로소, 주로 차량의 유니셜 조인트에 설치된다.In general, the universal joint is a device for freely transmitting power when two axes intersect at an angle, and is mainly installed in a universal joint of a vehicle.

도 1은 종래 기술에 따른 유니버셜 조인트의 분해 사시도이고, 도 2는 종래 기술에 따른 유니버셜 조인트의 결합 단면도이다.1 is an exploded perspective view of a universal joint according to the prior art, Figure 2 is a cross-sectional view of the coupling of the universal joint according to the prior art.

종래의 유니셜조인트는 구동력을 인가받아 회전되는 회전되는 구동축(102)에 형성되는 플랜지 요크(104)와, 구동력을 전달받는 피동축(106)에 형성되는 튜브 요크(108)와, 상기 두 요크(104,108) 사이에 십자 형태로 끼워지는 십자 저널(110)과, 상기 십자 저널(110)과 두 요크(104,108) 사이에 끼워져 양측을 회전 가능하게 지지하는 니들 롤러(116)와, 상기 니들 롤러(116)가 내측 둘레에 안착되고 외주면이 상기 두 요크의 내측면에 삽입되는 베어링 케이스(118) 등으로 구성된다.Conventional universal joints include a flange yoke 104 formed on a rotating drive shaft 102 that is rotated by a driving force, a tube yoke 108 formed on a driven shaft 106 that receives a driving force, and the two yokes. A cross journal 110 inserted in a cross shape between the 104 and 108, a needle roller 116 inserted between the cross journal 110 and two yokes 104 and 108 to rotatably support both sides, and the needle roller ( 116 is seated around the inner circumference and the outer circumferential surface is composed of a bearing case 118 or the like inserted into the inner surfaces of the two yokes.

이러한, 유니버셜 조인트는 구동축(102)의 회전력이 튜브 요크(108)와 플랜지 요크(104) 사이에 교차되게 장착되는 십자 저널(110)을 통해 전달되고, 이때 십자 저널(110)은 양측 요크(104,108) 사이에서 일정 각도로 회전되면서 양측의 각도 변화를 보상한다.Such a universal joint is transmitted through a cross journal 110 in which the rotational force of the drive shaft 102 is alternately mounted between the tube yoke 108 and the flange yoke 104, where the cross journal 110 has both yokes 104, 108. Rotates at an angle between) to compensate for changes in both sides.

그러나, 상기한 바와 같은 종래 기술에 따른 유니버셜 조인트는 베어링 케이스가 튜브 요크 및 플랜지 요크의 내주면에 삽입되는 상태로 끼워지기 때문에 구동력 전달시 베어링 케이스와 요크 내주면 사이에 슬립이 발생되어 소음 및 진동이 발생되고, 이로 인하여 구동력 전달 효율이 저하되는 문제점이 있다.However, since the universal joint according to the prior art as described above is inserted in the state in which the bearing case is inserted into the inner circumferential surfaces of the tube yoke and the flange yoke, slip is generated between the bearing case and the yoke inner circumferential surface when the driving force is transmitted, thereby generating noise and vibration. As a result, there is a problem that the driving force transmission efficiency is lowered.

본 발명은 상기한 문제점을 해결하기 위하여 창출된 것으로서, 본 발명의 목적은 베어링 케이스와 요크 사이에 슬립이 발생되지 않도록 고정시켜 구동력 전달시 베어링 케이스와 요크 사이의 슬립으로 인한 소음 및 진동이 발생되는 것을 방지하고, 구동력 전달 효율을 향상시킬 수 있는 유니버셜 조인트 구조를 제공하는 데 있다.The present invention was created in order to solve the above problems, and an object of the present invention is to fix the slip between the bearing case and the yoke so that noise and vibration are generated due to the slip between the bearing case and the yoke when the driving force is transmitted. It is to provide a universal joint structure that can prevent the damage, and improve the driving force transmission efficiency.

플랜지 요크(6) 및 튜브 요크(8)가 각각 십자축(10)에 직교하는 방향으로 끼워지고, 두 요크(6,8)와 십자축(10) 사이에 니들 롤러(12)가 내측 둘레면에 삽입되는 베어링 케이스(16)가 삽입되어 조립이 완료된다.The flange yoke 6 and the tube yoke 8 are fitted in the direction orthogonal to the cross shaft 10, respectively, and the needle roller 12 between the two yokes 6, 8 and the cross shaft 10 has an inner circumferential surface. The bearing case 16 is inserted into the insert is completed.

이러한 상태에서, 구동축(2)의 회전력이 튜브 요크(8)와 플랜지 요크(6) 사이에 교차되게 장착되는 십자 저널(10)을 통해 전달되고, 이때 십자 저널(10)은 양측 요크(4,6) 사이에서 일정 각도로 회전되면서 양측의 각도 변화를 보상한다.In this state, the rotational force of the drive shaft 2 is transmitted through the cross journal 10 mounted alternately between the tube yoke 8 and the flange yoke 6, where the cross journal 10 is connected to both yokes 4, 6) Compensate the change of angle of both sides while rotating at a certain angle between.

이때, 베어링 케이스(16)의 둘레방향으로 형성되는 걸림홈(20)에 두 요크(4,6)의 지지대(24) 끝부분에 형성되는 걸림턱(26)이 상기 걸림홈(20)에 삽입되어, 구동력 전달시 베어링 케이스(16)가 튜브 요크(8) 및 플랜지 요크(6) 내측면에서 슬립되는 것을 방지한다.At this time, the locking jaw (26) formed at the ends of the support (24) of the two yokes (4, 6) in the locking groove 20 formed in the circumferential direction of the bearing case 16 is inserted into the locking groove (20). This prevents the bearing case 16 from slipping on the inner surfaces of the tube yoke 8 and the flange yoke 6 during transmission of the driving force.

따라서, 상기와 같이 구성되고 작용되는 본 발명에 따른 유니버셜 조인트 구조는 베어링 케이스의 상측면에 걸림홈을 형성하고 플랜지 요크와 튜브 요크의 상면에 지지대를 형성하여 상기 걸림홈에 지지대의 걸림턱이 걸림 작용되도록 함으로써, 구동력 전달시 베어링 케이스가 요크 내측면에서 공회전되는 것을 방지하여, 베어링 케이스의 슬립으로 발생되는 소음 및 진동을 저감시키고, 동력 전달효율을 향상시킬 수 있다.Therefore, the universal joint structure according to the present invention constructed and acted as described above forms a locking groove on the upper side of the bearing case and a support on the upper surface of the flange yoke and the tube yoke so that the locking jaw of the support is caught in the locking groove. By acting, the bearing case is prevented from idling at the yoke inner side during transmission of the driving force, thereby reducing the noise and vibration generated by the slip of the bearing case, and improving the power transmission efficiency.
