At this time, as shown in Fig. 4, the bottom surface of the first flange coupling plate 110 in which the hook insertion hole 121c is formed is provided with a hook engaging projection 121d formed to be stepped to a predetermined depth. The hook head 123e of the fixing hook 123d is engaged with the hook engaging projection 121d, so that the coupling state of the outer ring 121 and the cap 123 is maintained.
캡(123)은 외부링(121)에 착탈가능하게 결합되며 너트(40)의 풀림이 방지되도록 지지한다. 캡(123)은 도 6에 도시된 바와 같이 외경이 캡삽입홈(121b)에 대응되게 형성되어 캡삽입홈(121b)에 끼움결합된다.The cap 123 is detachably coupled to the outer ring 121 and supports to prevent loosening of the nut 40 . As shown in FIG. 6 , the cap 123 is formed to have an outer diameter corresponding to the cap insertion groove 121b and is fitted into the cap insertion groove 121b.
캡(123)의 내부에는 도 3에 도시된 바와 같이 내부삽입관(123a)이 하부를 향해 형성된다. 내부삽입관(123a)의 가운데 영역에는 볼트(30)가 삽입되는 볼트삽입공이 관통형성된다. 내부삽입관(123a)의 내벽면에는 내부이빨(123b)이 형성되고, 내부삽입관(123a)의 외벽면에는 마주보는 방향으로 한 쌍의 역회전방지돌기(123c)가 구비된다. Inside the cap 123, as shown in FIG. 3, an internal insertion tube 123a is formed downward. A bolt insertion hole into which the bolt 30 is inserted is formed through the middle region of the inner insertion tube 123a. An inner tooth (123b) is formed on the inner wall surface of the inner insertion tube (123a), and a pair of anti-reverse projections (123c) are provided on the outer wall surface of the inner insertion tube (123a) in the opposite direction.
내부이빨(123b)은 내부삽입관(123a)의 반경방향 외측을 향해 요철이 반복되게 형성된다. 내부이빨(123b)에는 육각형 또는 다각형 형태의 볼트(30) 또는 너트(40)의 모서리가 끼워지게 형성된다. 이에 의해 볼트(30) 또는 너트(40)가 회전될 때 내부삽입관(123a)과 일체로 형성된 캡(123)도 캡삽입홈(121b) 내부에서 함께 회전된다. The inner tooth (123b) is formed to repeat irregularities toward the radially outer side of the inner insertion tube (123a). The inner teeth (123b) are formed to fit the corners of the hexagonal or polygonal bolt (30) or nut (40). Accordingly, when the bolt 30 or the nut 40 is rotated, the cap 123 integrally formed with the inner insertion tube 123a is also rotated within the cap insertion groove 121b.
역회전방지돌기(123c)는 내부삽입관(123a)의 외벽면에서 외부링(121)의 외부이빨(121a)을 향해 돌출되게 구비된다. 역회전방지돌기(123c)는 캡(123)이 볼트(30)와 너트(40)가 결합되는 방향으로 회전될 때는 외부이빨(121a)을 타고 넘으며 동일한 방향으로 회동되며 캡(123)이 회전되도록 한다. The reverse rotation prevention protrusion 123c is provided to protrude from the outer wall surface of the inner insertion tube 123a toward the outer teeth 121a of the outer ring 121. The reverse rotation prevention protrusion 123c is rotated in the same direction while riding over the external teeth 121a when the cap 123 is rotated in the direction in which the bolt 30 and the nut 40 are coupled, and the cap 123 is rotated. make it possible

On the other hand, the reverse rotation prevention protrusion 123c is inserted between the external teeth 121a when the cap 123 is rotated in a direction in which the bolt 30 and the nut 40 are loosened to prevent the cap 123 from rotating.
한편, 캡(123)의 외주연에는 마주보는 방향으로 한 쌍의 고정후크(123d)가 구비된다. 고정후크(123d)는 하부에 후크머리(123e)가 형성된다. 고정후크(123d)는 캡(123)이 외부링(121)에 끼워질 때, 탄성적으로 내측으로 오무려지며 후크삽입장공(121c)으로 삽입된다. 그리고, 후크삽입장공(121c)의 외부로 돌출된 후크머리(123e)는 도 4에 도시된 바와 같이 탄성적으로 복귀되며 후크걸림턱(121d)에 걸려진다. On the other hand, the outer periphery of the cap 123 is provided with a pair of fixing hooks 123d in the opposite direction. The fixing hook (123d) is formed with a hook head (123e) at the bottom. When the cap 123 is fitted to the outer ring 121, the fixing hook 123d is elastically engraved inward and is inserted into the hook insertion hole 121c. Then, the hook head 123e protruding to the outside of the hook insertion long hole 121c is elastically returned as shown in FIG. 4 and is caught on the hook engaging projection 121d.
이렇게 후크머리(123e)가 후크걸림턱(121d)에 걸려지면서 캡(123)과 외부링(121)의 고정상태가 견고하게 유지되게 된다.In this way, while the hook head 123e is caught on the hook engaging jaw 121d, the fixed state of the cap 123 and the outer ring 121 is firmly maintained.
이중와셔(125)는 외부링(121)의 바닥면에 형성된 와셔안착면(121e)에 끼움결합되어 볼트(30) 또는 너트(40)의 풀림이 방지되게 하여 결합구속력이 향상되게 한다. 이중와셔(125)는 도 3에 도시된 바와 같이 외경이 서로 다른 상부와셔(126)와 하부와셔(127)가 서로 일체로 결합되어 형성된다. The double washer 125 is fitted to the washer seating surface 121e formed on the bottom surface of the outer ring 121 to prevent loosening of the bolt 30 or the nut 40, thereby improving the coupling force. The double washer 125 is formed by integrally coupling an upper washer 126 and a lower washer 127 having different outer diameters to each other, as shown in FIG. 3 .
상부와셔(126)의 외경(R1)은 외부이빨(121a)에 내접하는 가상의 원 보다 작게 형성되어 와셔안착면(121e)에 안착될 수 있게 구비된다. 상부와셔(126)의 내경은 볼트(30)의 볼트축(31)에 대응되게 형성된다. The outer diameter R1 of the upper washer 126 is formed to be smaller than an imaginary circle inscribed with the outer teeth 121a and is provided to be seated on the washer seating surface 121e. The inner diameter of the upper washer 126 is formed to correspond to the bolt shaft 31 of the bolt 30 .
하부와셔(127)의 외경(R2)은 링결합공(113)에 대응되게 형성된다. 이에 의해 외부링(121)에 이중와셔(125)가 끼워졌을 때, 도 4에 도시된 바와 같이 배면의 링결합공(113) 내부에 하부와셔(127)가 삽입되어 외부로 노출된다. 하부와셔(127)의 내경은 상부와셔(126)와 동일하게 볼트(30)의 볼트축(31)에 대응되게 형성된다. The outer diameter R2 of the lower washer 127 is formed to correspond to the ring coupling hole 113 . Accordingly, when the double washer 125 is fitted to the outer ring 121, the lower washer 127 is inserted into the ring coupling hole 113 on the rear surface as shown in FIG. 4 and exposed to the outside. The inner diameter of the lower washer 127 is formed to correspond to the bolt shaft 31 of the bolt 30 in the same way as the upper washer 126 .
상부와셔(126)의 두께(d1)는 0.5mm 내외로 형성되고, 하부와셔(127)의 두께(d2)는 2mm 내외로 상부와셔(126) 보다 두껍게 형성된다. The thickness d1 of the upper washer 126 is formed to be about 0.5 mm, and the thickness d2 of the lower washer 127 is formed to be thicker than the upper washer 126 by about 2 mm.
이에 의해 도 6에 도시된 바와 같이 이중와셔(125)가 외부링(121)의 와셔안착면(121e)에 끼워진 후, 볼트(30) 또는 너트(40)가 결합되고 캡(123)이 외부링(121)에 결합되었을 때, 볼트(30) 또는 너트(40)의 하부가 상부와셔(126)를 압착하게 되고, 볼트축(31)이 하부와셔(127)의 내부에 위치하게 된다. Accordingly, as shown in FIG. 6, after the double washer 125 is fitted to the washer seating surface 121e of the outer ring 121, the bolt 30 or the nut 40 is coupled and the cap 123 is the outer ring. When coupled to (121), the lower part of the bolt 30 or the nut 40 presses the upper washer 126, and the bolt shaft 31 is positioned inside the lower washer 127.
이에 따라 볼트(30)가 삽입된 후 너트(40)에 체결되면, 볼트(30)와 너트(40)의 체결력에 의해 상부와셔(126)와 하부와셔(127)가 링결합공(113) 측으로 가압되면서 볼트(30) 또는 너트(40)의 접촉면적을 증가시켜 마찰면적이 커진 만큼 토크가 증가하여 풀림방지 역할을 하게 된다. Accordingly, when the bolt 30 is inserted and fastened to the nut 40 , the upper washer 126 and the lower washer 127 move toward the ring coupling hole 113 by the fastening force of the bolt 30 and the nut 40 . As the pressure increases, the contact area of the bolt 30 or the nut 40 is increased, and the torque increases as the friction area increases, thereby preventing loosening.
특히, 본 발명에서는 서로 직경이 서로 다른 상부와셔(126)와 하부와셔(127)가 각각 볼트(30) 또는 너트(40)의 하부와 볼트축(31)을 함께 지지하여 접촉면적을 더 증가하게 되므로 마찰면적이 더 커지게 되므로 풀림방지 효과도 증가하게 된다. In particular, in the present invention, the upper washer 126 and the lower washer 127 having different diameters support the lower part of the bolt 30 or the nut 40 and the bolt shaft 31 together to further increase the contact area. As a result, the friction area becomes larger, and thus the anti-loosening effect is also increased.
여기서, 본 발명에 따른 이중와셔(125)는 상부와셔(126)와 하부와셔(127)가 일체로 결합된 형태이나, 경우에 따라 독립적으로 형성될 수도 있다.Here, the double washer 125 according to the present invention is a form in which the upper washer 126 and the lower washer 127 are integrally coupled, but may be formed independently in some cases.
