본 발명은 이탈 방지용 더스트 시일 링 형상에 관한 것으로, 더욱 상세하게는 회전축에 설치되는 탄성체의 외측으로 구비되는 케이싱의 구조로 이탈을 방지하도록 하기 위한 더스트 시일 링 형상에 관한 것이다.The present invention relates to a dust seal ring shape for prevention of departure, and more particularly, to a dust seal ring shape for preventing departure from the structure of the casing provided on the outer side of the elastic body installed on the rotating shaft.

일반적으로 더스트시일(dust seal)은 먼지등의 유입을 방지하기 위한 것으로, 기본적으로 내후성, 내열 내한성, 내약품성과 같은 성질이 요구되며, 모든 사용 조건에 적응할 수 있게 각종 재료가 있다. 이음을 갖는 유압기기등에 사용되며, 더스트 시일은 회전운동이나 왕복운동 하는 기계 내부로 먼지나 기타 이물질의 유입을 방지하기 위한 것이다.In general, dust seals are used to prevent the inflow of dust and the like, and are basically required to have properties such as weather resistance, heat resistance cold resistance, and chemical resistance, and there are various materials to adapt to all use conditions. It is used in hydraulic equipment with joints, and dust seal is to prevent the inflow of dust or other foreign matter into the rotating or reciprocating machine.

탄성체인 립은 우레탄 재질의 더블립(DOUBLE LIP)을 가진 패킹(PACKING)으로 외부로부터의 이물질 혼입을 강력하게 방지하여 주므로 실린더의 보호 및 로드패킹(ROD PACKING)의 기능을 유지, 증진시켜 준다.The lip, which is an elastic body, is a packing with a urethane double lip, which strongly prevents foreign substances from entering from the outside and thus maintains and enhances the functions of cylinder protection and road packing.

도 1은 종래의 이탈을 방지하기 위한 단면도로서, 회전운동이나 왕복운동하는 축(230)에 설치되고 탄성체로 되는 립(lip)의 외측에 설치되는 케이싱(220)을 하우징(250)의 삽입홈에 설치하고 상기 더스트 시일이 이탈하지 않도록 삽입홈에 스냅링(240)을 설치하도록 설치홈을 가공하여 더스트시일이 이탈하지 않도록 고정한 구성이다.1 is a cross-sectional view for preventing a conventional departure, the insertion groove of the housing 250 is provided with a casing 220 which is installed on the shaft 230 that rotates or reciprocates and which is installed outside of a lip that is an elastic body.

이렇게 상기 내측링(30)과 수분방지유입립(44)은 외측링(40)에 구비된 내측의 원형홀(41)에 동시에 사출성형에 의해 결합되어 고정됨으로서 종래에 외측링(20)과 내측링(10)을 제작함에 접착제를 사용하던 것을 본 발명에서는 상기 외측링(40)을 성형한 후에 상기 내측링(30)과 수분방지립(44)을 성형하기 위한 탄성소재를 삽입하여 금형으로 동시 사출 성형하여 상기 내측링(30)과 수분유입방지립(32)을 외측링(40)에 무접착으로 결합시킴으로서, 틀어짐 없이 단단히 고정될 수 있으며, 종래에 접착제를 사용하여 발생하던 공정을 줄일 수 있고 접착제를 이용하여 결합시킬 때 접착부위가 틀어져 발생하는 불량 더스트시일 링(101)의 발생을 방지할 수 있다.In this way, the inner ring 30 and the moisture-proof inlet granules 44 are fixed to the inner circular hole 41 provided in the outer ring 40 at the same time by being combined by injection molding and fixed to the outer ring 20 and the inner side. In the present invention, the adhesive was used to fabricate the ring 10, and then, after forming the outer ring 40, an elastic material for forming the inner ring 30 and the moisture resistant lip 44 was inserted into the mold at the same time. By bonding the inner ring 30 and the moisture inflow prevention lip 32 to the outer ring 40 by non-adhesion by injection molding, it can be firmly fixed without being twisted, and can reduce the process that occurred using an adhesive in the past And it is possible to prevent the occurrence of the poor dust seal ring 101 caused by the adhesive portion is twisted when bonding using an adhesive.

상기에서 본 발명에 따른 바람직한 실시예를 설명하였으나, 이는 예시이며, 다양한 변화와 변형이 가능함은 당업자는 알 수 있을 것이나, 이는 모두 본 출원의 권리범위에 속하게 됨은 첨부된 청구범위를 통해서 알 수 있을 것이다.Although a preferred embodiment according to the present invention has been described above, it is an example, and various changes and modifications will be apparent to those skilled in the art, which can be understood through the appended claims that all belong to the scope of the present application. will be.

이상에서 상세히 설명한 바와 같이, 본 발명은 외측링에 일체로 된 돌기에 의해 추가부품이 필요없이 설치하기 때문에 생산효율이 증가하고 가공단가가 줄어들고, 더스트 시일을 금속재질에 의해서는 접착에 의해 제조하고 플라스틱 재질에 의해서는 무접착으로 조립하여 제작공정을 줄여 생산효율을 높아지는 효과가 있다.As described in detail above, the present invention is installed without the need for additional parts by the protrusions integral to the outer ring, the production efficiency is increased, the processing cost is reduced, and the dust seal is manufactured by bonding with a metal material The plastic material has an effect of increasing the production efficiency by reducing the manufacturing process by assembling non-adhesive.
