본 고안은 자동차용 자재 이음의 니이들 캡 실(SEAL)에 관한 것으로서, 더욱 상세하게는 니이들 캡 실의 구조를 개선 시킴으로써, 실링 효과를 발휘하여 소음발생 및 파손을 방지함과 동시에 오일의 누유를 완벽하게 방지할 수 있는 자동차용 자재 이음의 니이들 캡 실에 관한 것이다.The present invention relates to a needle cap seal (SEAL) of a material joint for automobiles, and more particularly, by improving the structure of the needle cap seal, exhibiting a sealing effect to prevent noise and breakage, and at the same time oil leakage It relates to a needle cap seal of a joint of a vehicle material which can completely prevent the.
일반적으로, 자재 이음은 각도를 가진 두 개의 축 사이에 동력을 전달할 때에 사용되는 것이며, 제1도에 도시되어 있는 니이들 캡(6)은 자재 이음의 십자축(12)을 감싸고 있고, 상기 니이들 캡(6)의 끝단 돌출부(7)에 장착되어 있는 실(1)은 십자축(12) 내부의 오일 저장부(8)에 내장되어 있는 오일의 누유를 방지하도록 되어 있다.Generally, the material joint is used to transfer power between two angled axes, and the needle cap 6 shown in FIG. 1 encloses the cross shaft 12 of the material joint. The seal 1 attached to the protruding portion 7 of these caps 6 is configured to prevent leakage of oil contained in the oil reservoir 8 inside the cross shaft 12.
종래의 니이들 캡(6)과 실(1)을 도시한 제2도를 참고하여 니이들 캡(6)과 실(1)을 자세히 살펴보면, 상기 니이들 캡(6)의 내주연에는 니이들 베어링(9)이 장착되어 있고, 상기 실(1)은 니이들 캡(6)의 끝단 돌출부(7)에 장착되어 있으며, 여기서, 실(1)은 각각 금속부재(3)와 고무부재(4)로 이루어져 있되, 상기 금속부재(3)는 십자축(12) 외주연에 접하게 되고 동시에 상기 고무부재(4)는 니이들 캡(6)의 끝단 돌출부(7)에 끼워지게 되도록 이루어져 있다.Looking at the needle cap 6 and the thread 1 in detail with reference to FIG. 2, which shows the conventional needle cap 6 and the thread 1, the needle on the inner periphery of the needle cap 6 A bearing 9 is mounted, and the seal 1 is mounted to the end projection 7 of the needle cap 6, where the seal 1 is a metal member 3 and a rubber member 4, respectively. The metal member (3) is in contact with the outer periphery of the cross shaft (12) and at the same time the rubber member (4) is to be fitted to the end projection (7) of the needle cap (6).
이때, 상기 실(1)은 금속부재(3)를 통하여 십자축(12)과 서로 금속면으로 접하게 됨으로 완벽한 실링효과를 기대하기 힘들고 소음발생의 우려도 있다.At this time, since the seal 1 is in contact with the cross shaft 12 and the metal surface through the metal member 3, it is difficult to expect a perfect sealing effect and there is a fear of noise.
특히, 실(1)의 외부가 금속부재(3)이므로 추진축의 작동시 실(1)이 변형되거나 이탈될 우려가 있고, 이로 인하여 오일 누유 및 소음이 발생하는 단점이 있다.In particular, since the outside of the seal 1 is a metal member 3, there is a risk that the seal 1 is deformed or disengaged during the operation of the propulsion shaft, which causes oil leakage and noise.
본 고안은 상기와 같은 문제점을 해결하기 위해 인출한 것으로서, 본 고안의 목적은 니이들 캡 실의 구조를 개선하여 실과 십자축의 접촉부분에 밀착성과 탄력성을 부여하므로써, 진동 및 소음의 방지는 물론 실의 변형이나 이탈을 방지하고, 특히, 오일의 누유를 완벽하게 없앨 수 있는 자동차용 자재 이음의 니이들 캡 실을 제공하는데 그 목적이 있는 것이다.The present invention has been drawn to solve the above problems, the object of the present invention is to improve the structure of the needle cap thread to give adhesion and elasticity to the contact portion of the thread and the cross-shaft, thereby preventing vibration and noise as well as It is an object of the present invention to provide needle cap seals for automobile joints which can prevent deformation and detachment of oil and, in particular, completely eliminate oil leakage.
이하, 첨부도면을 참고하여 본 고안을 상세히 설명하면 다음과 같다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.
본 고안은 자동차용 자재 이음의 니이들 캡 실에 있어서, 니이들 캡 실(11)의 바닥면에 십자축(12)관통홀을 갖는 용기형 하우징 형태의 금속부재(13)와, 상기 금속부재(13)의 내주연에 삽입됨과 동시에 바닥면 및 관통홀에 결착되는 환형의 고무부재(14)로 이루어진 것이다.The present invention is a needle cap seal of the automobile joint, the metal member 13 in the form of a container-type housing having a cross-shaft 12 through hole on the bottom surface of the needle cap seal 11, and the metal member It is composed of an annular rubber member 14 that is inserted into the inner periphery of (13) and is bound to the bottom surface and the through hole.
특히, 상기 고무부재(14)의 내주연에는 2개 이상의 돌기(15)가 방사상으로 형성되어 있다.In particular, two or more projections 15 are formed radially on the inner circumference of the rubber member 14.
이와 같은 본 고안에 대한 구성과 작용효과를 더욱 상세히 설명하면 다음과 같다.Referring to the configuration and effect of the present invention in more detail as follows.
본 고안의 니이들 캡(6)과 실(11)의 단면을 도시한 제3도를 참고하여 보면, 니이들 베어링(9)을 내장한 니이들 캡(6)의 돌출부(7)에 결착되는 실(11)은 금속부재(13)와 고무부내(14)로 형성되어지되, 상기 금속부재(13)는 바닥면에 십자축(12) 관통홀을 갖는 용기형 하우징 형태의 형상으로 이루어져 있으며, 상기 금속부재(13)의 외주연은 니이들 캡(6)의 끝단 돌출부(7)에 안쪽에 결착되고, 상기 금속부재(13)의 내주연으로 고무부재(14)가 결착되어 있다.Referring to FIG. 3 showing a cross section of the needle cap 6 and the seal 11 of the present invention, the needle cap 9 is attached to the protrusion 7 of the needle cap 6 incorporating the needle bearing 9 therein. The seal 11 is formed of a metal member 13 and the rubber portion 14, the metal member 13 is formed in the shape of a container-type housing having a cross-shaft 12 through hole in the bottom surface, The outer circumferential edge of the metal member 13 is bound to the inside of the end projection 7 of the needle cap 6, and the rubber member 14 is bound to the inner circumference of the metal member 13.
이때, 상기 금속부재(13)는 실(11)을 지지해 주는 역할을 하여서 실(11)의 변형을 방지함과 동시에 상기 실(11)이 니이들 캡(6)으로부터 이탈되는 것을 방지한다.At this time, the metal member 13 serves to support the seal 11 to prevent deformation of the seal 11 and to prevent the seal 11 from being separated from the needle cap 6.
한편, 금속부재(13) 내주연에 결착되어 있는 환형의 고무부재(14)에 다수의 돌기(15)가 방사상으로 형성되어져 있고, 상기 돌기(15) 중 일부는 금속부재(13)에 결착되어 있고, 또 다른나머지 일부는 십자축(12)에 밀착되어진다.On the other hand, a plurality of projections 15 are formed radially in the annular rubber member 14 which is bound to the inner circumference of the metal member 13, and some of the projections 15 are bound to the metal member 13 And the other part is in close contact with the cross shaft 12.
여기서, 상기 돌기(15)중 A돌기(15-A)와 E돌기(15-E)는 금속부재(13) 내주연에 결착되고, 끝단이 곡면으로 형성되어 있는 B돌기(15-B)는 십자축(12)의 곡면부에 결착되어 실링효과를 높임과 동시에 실(11)의 이탈을 방지하게 되며, 끝단이 사각형으로 형성되어 있는 C돌기(15-C)와 D돌기(15-D) 사이에는 V홈이 형성되고, 상기 C돌기(15-C)와 D돌기(15-D)가 압축되면서 십자축(12)에 결착되므로 완벽한 실링효과를 얻을 수 있게 된다.Here, the projections 15-A and the projections 15-A of the projections 15 are bound to the inner circumference of the metal member 13, and the projections B-form 15-B having the curved ends are formed. It is bound to the curved portion of the cross-shaft 12 to increase the sealing effect and to prevent the separation of the seal 11, C end (15-C) and D protrusion (15-D) is formed in a square end A V groove is formed therebetween, and the C protrusion 15-C and the D protrusion 15-D are compressed and bound to the cross shaft 12, thereby obtaining a perfect sealing effect.
즉, 제3도에 하나의 구현예로 예시한 바와 같이 환형의 고무부재(14)에는 4개의 돌기(15-A,15-B,15-C,15-D)가 십자축(12)의 외주연과 밀착되므로써, 오일의 누유를 완벽하게 방지할 수 있도록 구성된 실(11)이 제조될 수 있다. 또한, 실(11)과 십자축(12)간의 접촉부에 고무부재(14)를 사용하므로써, 추진축 작동시 받는 충격력을 흡수하여 실(11)의 변형이나 이탈을 방지할 수 있고, 상기 실(11)과 십자축(12)간의 접촉부에서의 진동 및 소음을 없애는 동시에 상기 실(11)이 한쪽으로 쏠리는 현상을 방지할 수 있다.That is, as illustrated in FIG. 3 as one embodiment, the annular rubber member 14 has four projections 15-A, 15-B, 15-C, and 15-D of the cross shaft 12. By being in close contact with the outer circumference, a seal 11 configured to completely prevent leakage of oil can be manufactured. In addition, by using the rubber member 14 at the contact portion between the seal 11 and the cross shaft 12, the impact force received during the operation of the propulsion shaft can be absorbed to prevent deformation or detachment of the seal 11, and the seal 11 ) And the vibration of the contact portion between the cross shaft 12 and the noise can be eliminated at the same time, the phenomenon that the seal 11 is leaned to one side can be prevented.
상술한 바와 같이, 본 고안은 자동차용 자재 이음의 니이들 캡 실의 구조를 개선시키므로써, 실의 변형이나 이탈을 방지함과 동시에 추진축 작동시 십자축과 니이들 캡 접촉부의 진동이나 소음을 방지하고 특히, 오일의 누유를 완벽하게 방지할 수 있는 장점이 있다.As described above, the present invention improves the structure of the needle cap seal of the automobile material joint, thereby preventing deformation or detachment of the seal and at the same time preventing vibration or noise of the cross shaft and the needle cap contact portion during the operation of the propulsion shaft. In particular, there is an advantage that can completely prevent the leakage of oil.
