본 발명은 유니버설 조인트의 베어링 구조에 관한 것으로, 상세하게는 유니버설 조인트의 요크와 스파이더의 사이에 개재되어 스파이더를 회동가능하게 지지하는 베어링을 스크류에 체결에 의해 요크의 내주면에 고정시키므로써 구조를 단순화하여 유니버설 조인트를 구성하는 베어링의 결합 및 분해를 용이하게 할 수 있도록 한 유니버설 조인트의 고정구조에 관한 것이다.The present invention relates to a bearing structure of a universal joint, and in particular, the structure is simplified by fastening a bearing interposed between the yoke and the spider of the universal joint to support the spider to the inner circumferential surface of the yoke by fastening to a screw. The present invention relates to a structure for fixing a universal joint to facilitate coupling and disassembly of a bearing constituting the universal joint.

유니버설 조인트는 일정한 각도로 중심축선이 교차하는 두개의 축을 각 중심축선에 대해 자유로운 회전이 가능하도록 연결시킬때 사용하는 축이음 부재로, 추진축의 양단에 형성되어 있는 요크의 관통공으로 베어링을 개재하여 스파이더에 형성된 4개의 축중 대향면에 위치한 2개의 축을 요크의 관통공에 삽입시킨 다음, 외부로부터 요크의 관통공으로 베어링을 각각 삽입시켜 스파이더가 베어링에 의해 회동가능하게 지지되도록 하며, 상기한 과정후에는 요크의 관통공으로부터 베어링의 이탈이 방지되도록 요크의 내주연을 압입시키거나 제1도에 도시한 바와같이 스냅립(31)을 관통공(26)의 상부 주면에 형성된 요홈으로 삽입하여 베어링(22)을 고정시키게 된다.Universal joint is a shaft joint member used to connect two axes intersecting the central axis line at a certain angle to allow free rotation about each central axis line. It is a through hole of yoke formed at both ends of the propulsion shaft. After inserting the two shafts on the opposite surface of the four shafts formed in the through hole of the yoke, the bearing is inserted into the through hole of the yoke from the outside so that the spider is rotatably supported by the bearing. The inner periphery of the yoke is press-fitted to prevent the bearing from being separated from the through-hole of the bearing, or as shown in FIG. Will be fixed.

그러나, 상기한 바와같은 종래의 유니버설 조인트(30)는 요크(25)와 스파이더(21)의 결합후 베어링(22)의 이탈방지를 위해 스냅링(31)을 삽입시켜야 하므로 필수적으로 관통공(26)의 내주면으로 상기한 스냅링(31)이 삽입되도록 요홈을 형성시키는 한편, 수작업에 의해 스냅링(31)을 관통공(26)의 요홈으로 삽입시켜야 하므로 유니버설 조인트(30)의 제작이 까다롭고 스냅링(31)의 삽입에 많은 번거로움이 따랐으며, 압입에 의해 베어링(22)을 고정시킬 경우에는 내부구성부품의 점검시 베어링(22)의 분리가 곤란하고,프레스와 같은 대형의 압입장비가 필요하다는등의 문제점이 따랐다.However, since the conventional universal joint 30 as described above is required to insert the snap ring 31 in order to prevent the bearing 22 from being separated after the yoke 25 and the spider 21 are coupled, the through hole 26 is essential. While forming the groove so that the snap ring 31 is inserted into the inner circumferential surface of the groove, the snap ring 31 must be inserted into the groove of the through hole 26 by hand, which makes the production of the universal joint 30 difficult and the snap ring 31. ), A lot of cumbersome work was required, and when the bearing 22 is fixed by pressing, it is difficult to remove the bearing 22 when checking the internal components, and a large press-fitting equipment such as a press is required. Followed the problem.

본 발명에 의한 유니버설 조인트의 베어링 고정구조는 상기와 같은 종래의 문제점을 감안하여 안출한 것으로서, 본 발명의 목적은 요크의 고정공으로 삽입된 베어링을 스크류의 체결에 의해 고정시키므로써 유니버설 조인트의 구조를 단순화하는 한편, 베어링의 고정 및 탈거가 신속하고 용이하게 이루어질 수 있도록 한 유니버설 조인트를 제공하는데 있는 것이다.The bearing fixing structure of the universal joint according to the present invention has been devised in view of the above-mentioned conventional problems, and an object of the present invention is to fix the structure of the universal joint by fixing the bearing inserted into the fixing hole of the yoke by screwing. On the other hand, it is to provide a universal joint that allows fastening and dismounting of bearings quickly and easily.

상기와 같은 목적을 달성하기 위한 본 발명의 특징은, 유니버설 조인트의 요크와 스파이더의 사이에 개재되어 스파이더를 회전가능하게 지지되도록 한 베어링의 고정구조에 있어서, 요크의 관통공과 베어링과의 접촉면으로는 나사공을 형성하고 상기한 나사공으로는 스크류를 체결시킨 구조로 이루어진 것이다.A feature of the present invention for achieving the above object is, in the fixed structure of the bearing interposed between the yoke and the spider of the universal joint so as to rotatably support the spider, the contact surface of the through-hole and the bearing of the yoke To form a screw hole and the screw hole is made of a structure in which a screw is fastened.

이하, 본 발명에 의한 유니버설 조인트의 베어링 고정구조를 첨부된 도면을 참조하여 구체적으로 설명하면 다음과 같다.Hereinafter, the bearing fixing structure of the universal joint according to the present invention will be described in detail with reference to the accompanying drawings.

제2도는 본 발명에 의한 유니버설 조인트의 정면도이고, 제3도는 본 발명에 의한 유니버설 조인트의 폭방향 단면도로서, 본 발명에 의한 유니버설 조인트의 베어링 고정구조(10)는, 베어링(22)의 외주면과 요크(25)에 형성된 관통공(26)의 내주면이 접촉되도록 한 베어링(22)과 관통공(26)사이의 접촉면에 나사공(1)을 형성하므로써 베어링(22)의 일측 및 관통공(26)과 접하는 요크(25)의 일측에는 각각 반원형의 나사공(1A,1B)을 형성하고, 상기한 반원형의 나사공(1A,1B)이 조합되므로써 원형을 이루는 나사공(1)으로는 스크류(2)를 체결시키므로써 요크(25)의 관통공(26)으로부터 베어링(22)의 유동과 이탈을 방지하도록 한 것이다.FIG. 2 is a front view of the universal joint according to the present invention, and FIG. 3 is a cross-sectional view in the width direction of the universal joint according to the present invention, wherein the bearing fixing structure 10 of the universal joint according to the present invention has an outer circumferential surface of the bearing 22. One side and the through hole 26 of the bearing 22 are formed by forming the screw hole 1 in the contact surface between the bearing 22 and the through hole 26 which allow the inner circumferential surface of the through hole 26 formed in the yoke 25 to contact. On one side of the yoke 25 in contact with), semicircular threaded holes 1A and 1B are formed, respectively, and the above-mentioned semicircular threaded holes 1A and 1B are combined to form a circular threaded hole 1 as a screw (1). 2) by fastening to prevent the flow and separation of the bearing 22 from the through hole 26 of the yoke 25.

상기한 나사공(1)은 요크(25)에 형성되어 있는 관통공(26)의 내주면에 베어링(22)을 삽입시킨 상태에서 베어링(22)과 관통공(26)의 접촉면에 드릴링 작업을 통해 통공을 형성한 후, 상기한 통공의 내주면에 나사홈을 형성하므로써 간단히 이루어진다.The above-described screw hole 1 is drilled into the contact surface between the bearing 22 and the through hole 26 while the bearing 22 is inserted into the inner circumferential surface of the through hole 26 formed in the yoke 25. After the through hole is formed, the screw groove is simply formed on the inner circumferential surface of the through hole.

상기와 같은 본 발명에 의한 유니버설 조인트의 베어링 고정구조(10)의 작용 및 효과를 설명하면, 스파이더(21)의 회전을 지지하도록 한 베어링(22)을 요크(25)의 관통공(26)내에 고정시키는 작업시에는 베어링(22)의 일측에 형성된 반원형의 나사공(1A)및 요크(25)의 일측에 형성된 반원형의 나사공(1B)을 조합하여 원형의 나사공(1)을 이루도록 한후 상기한 나사공(1)에 스크류(2)를 체결시키면 베어링(22)은 상기한 스크류(2)에 의해 좌우방향으로의 회전이 억제되므로써 요크(25)의 관통공(26)에 삽입된 베어링(22)의 수평방향으로의 유동을 방지하게 되고, 또한 베어링(22)및 요크(25)의 일측에 형성된 반원형의 나사공(1A,1B)이 스크류(2)와 각각 치합되므로써 요크(25)로부터 베어링(22)의 길이방향의 유동이나 이탈이 방지되며,베어링(22)이나 스파이더(21)의 점검이나 교체를 위해 요크(25)로부터 베어링(22)을 탈거시키고자 할 경우에는 나사공(1)에 체결된 스크류(2)를 외부로 이탈시킴에 간단히 분리할 수 있게 된다.Referring to the operation and effect of the bearing fixing structure 10 of the universal joint according to the present invention as described above, the bearing 22 to support the rotation of the spider 21 in the through hole 26 of the yoke 25 At the time of fixing, the semi-circular screw hole 1A formed on one side of the bearing 22 and the semi-circular screw hole 1B formed on one side of the yoke 25 are combined to form a circular screw hole 1. When the screw 2 is fastened to one threaded hole 1, the bearing 22 is inserted into the through hole 26 of the yoke 25 by the rotation of the bearing 22 in the lateral direction by the screw 2 described above. 22 is prevented from flowing in the horizontal direction, and semicircular threaded holes 1A, 1B formed on one side of the bearing 22 and the yoke 25 are engaged with the screw 2, respectively, so that the yoke 25 Longitudinal flow or detachment of the bearing 22 can be prevented, and the bearing 22 and the spider 21 can be inspected or replaced. In order to remove the bearing 22 from the yoke 25 for the sieve, the screw 2 fastened to the screw hole 1 can be detached simply by detaching the screw 2.

이상에서와 같이 본 발명은 단순한 구조로 이루어져 유니버설 조인트의 제작을 간소화시킬 수 있고, 베어링(22)의 고정작업을 용이하게 할 수 있어 인력소모를 방지하는 한편, 작업효율을 높일 수 있으며, 스크류(2)의 분리만으로 베어링(22)의 탈거가 이루어지므로써 내부구성부품의 점검이나 교체를 신속하고 원활하게 하는 등의 효과가 있다.As described above, the present invention can be made of a simple structure to simplify the production of the universal joint, to facilitate the fixing work of the bearing 22, while preventing manpower consumption, while increasing the work efficiency, screw ( Since the bearing 22 is removed only by the separation of 2), there is an effect of quickly and smoothly inspecting or replacing the internal components.
