본 고안은 상대적으로 회전하는 배관 또는 기기를 접속하기 위한 로터리 조인트의 구조개량에 관한 것이다.The present invention relates to a structural improvement of a rotary joint for connecting a relatively rotating pipe or device.
또한, 본 고안에서 로터리 조인트라 함은 주로 플라스틱 압출기, 플라스틱 냉각 인출롤러, 고무관련기계에 사용되는 것으로 스팀 및 물, 열매체, 냉각수 등을 유입 및 배출시킬 때 롤이나 드럼에 연결 사용하는 것이다.In addition, the rotary joint in the present invention is mainly used in plastic extruders, plastic cooling take-out rollers, rubber-related machinery is used to connect to the roll or drum when inlet and discharge steam and water, heat medium, cooling water and the like.
첨부도면중 제2도는 종래 로터리 조인트의 종단면도로서, 원주면과 일측면에 관 이음부(18)가 형성되고 타측면이 완전 개방된 원통형 몸체(10)의 내측 중공부에 일측에는 플랜지(20)를 타측에는 관 이음부(21)를 형성한 연결관(11)이 헐겁게 삽설된 후 ; 상기 연결관에 스프링(17)과, 환형의 카본패킹(14)과, 내주면에 밀폐용 링(16)이 삽착된 환형의 밀폐부재(15)와, 그리고 한쌍의 베어링(12)을 상기의 순서대로 외삽하여 상기 연결관(11)을 회전자재로 지지한 상태에서 상기 부재(17)(14)(15)(12)가 몸체(10)로 부터 빠져 나오지 못하도록 상기 몸체의 개방측 내주면에 고정링(13)을 설치한 구성이었다.2 is a longitudinal cross-sectional view of a conventional rotary joint, in which a pipe fitting 18 is formed on one side of the circumferential surface, and a flange 20 on one side of the inner hollow portion of the cylindrical body 10 in which the other side is completely open. ) Loosely inserted into the other side of the connecting pipe (11) forming a pipe joint 21; The spring 17, the annular carbon packing 14, the annular sealing member 15 in which the sealing ring 16 is inserted into the inner circumferential surface, and the pair of bearings 12 are connected to the connecting pipe. Fixing ring on the inner circumference of the open side of the body to prevent the member 17, 14, 15, 12 from exiting the body 10 in the state in which it is extrapolated to support the connecting pipe 11 with the rotating material. It was the structure which installed (13).
그러나, 상기 구성의 로터리 조인트는 장시간 사용시, 베어링(12)과 그 내부에서 회전자재되는 연결관(11) 사이의 조립 허용오차에 의해 편회전이 발생되고, 이에 의해 베어링의 기계적 마모가 심화되면서 회전소음 및 진동이 발생되며, 이때의 소음 및 진동이 가지고 있는 충격력이 카본패킹(14)에 반복적으로 작용되어, 상기 카본패킹(14)이 취성파괴되는 문제점이 있었다.However, when the rotary joint of the above configuration is used for a long time, one-turn rotation occurs due to an assembly tolerance between the bearing 12 and the connecting pipe 11 that is rotated therein, thereby increasing the mechanical wear of the bearing and rotating it. Noise and vibration are generated, and the impact force of the noise and vibration at this time is repeatedly acted on the carbon packing 14, there was a problem that the carbon packing 14 brittle fracture.
따라서, 상기 구성의 종래 로터리 조인트의 연결관(11)과 몸체(10) 사이의 결합부에는 수밀 또는 기밀을 위한 특별한 수단이 요구되었다.Therefore, a special means for watertight or airtight is required at the joint between the connecting pipe 11 and the body 10 of the conventional rotary joint of the above configuration.
본 고안은 이러한 종래의 문제점을 개선하고자 안출된 것으로, 종래 카본패킹을 석면재의 글랜드 패킹으로 대체함으로써 수밀 또는 기밀을 위한 별도의 밀봉수단이 필요없을 뿐 아니라, 글랜드 패킹에 윤활 그리스(grease)를 공급하여 항상 습윤 팽출된 상태를 유지함으로써 조립허용오차에 의한 연결관의 회전소음 및 진동을 완전 방지함과 동시에 로터리 조인트의 내구수명을 연장되게 하는 특징이 있다.The present invention was devised to improve such a conventional problem, and by replacing the conventional carbon packing with the gland packing of asbestos material, there is no need for a separate sealing means for watertightness or airtightness, as well as lubricating grease in the gland packing. It is characterized by extending the endurance life of the rotary joint at the same time to completely prevent the rotation noise and vibration of the connection pipe due to the assembly allowable error by maintaining the wet swelled state by supplying.
이하, 첨부도면에 의거 본 고안에 따른 로터리 조인트의 구성을 상세히 설명하면 다음과 같다.Hereinafter, the configuration of the rotary joint according to the present invention based on the accompanying drawings in detail as follows.

Configuration.
여기서 미설명 부호 9는 스터핑박스(2)와 몸체 사이의 용접부위를 나타낸다.Here, reference numeral 9 denotes a welding portion between the stuffing box 2 and the body.
이상과 같이 구성되는 본 고안에 따른 로터리 조인트의 작용 및 효과를 설명하면 다음과 같다.Referring to the operation and effects of the rotary joint according to the present invention configured as described above are as follows.
제1도에서 보는 바와 같이, 본 고안에서는 연결관(1)의 벽면에 윤활유 공급관로(8)를 형성하고, 종래의 로터리 조인트의 베어링과 카본패킹 대신에 석면재의 글랜드 패킹(3)으로 대체하여 글랜드 패킹(3)이 가지는 탄성을 이용하여 종래의 로터리 조인트의 스프링 역할을 대체할 뿐아니라 회전하는 연결관(1)을 지지하는 지지체로서의 역할도 한다.As shown in FIG. 1, in the present invention, the lubricant supply pipe 8 is formed on the wall of the connecting pipe 1, and replaced with a gland packing 3 of asbestos material instead of the bearing and carbon packing of the conventional rotary joint. By using the elasticity of the gland packing (3) to replace the role of the spring of the conventional rotary joint, and also serves as a support for supporting the rotating tube (1).
또한, 스터핑박스(2)와 글랜드 패킹(3)과 패킹누르개(4) 및 조오(7)를 스터드볼트(5)와 너트(6)로 밀접시키므로써 냉각수 등의 유체의 누출을 방지하였으며, 윤활유 공급관로(8)를 통해 유입되는 윤활 그리스로, 연결관(1) 및 글랜드 패킹(3) 사이의 상대적인 회전에 의한 마찰열을 냉각하므로써 장치의 수명을 연장하였다.In addition, the stuffing box (2), the gland packing (3), the packing presser (4) and the jaws (7) by the stud bolt (5) and the nut (6) to close the leakage of fluid such as cooling water, The lubricating grease flowing through the lubricating oil supply line 8 extends the life of the device by cooling the frictional heat due to the relative rotation between the connecting pipe 1 and the gland packing 3.
이와 같이, 본 고안의 로터리 조인트는 반영구적으로 사용할 수 있어 경비절감은 물론이고 유체의 누출을 최소화할 수 있으며, 뛰어난 냉각효과를 가지고 있을 뿐 아니라 종래의 것과 같이 복잡한 구조가 아니기 때문에 고장 및 수리의 필요가 없는 장점이 있는 것이다.In this way, the rotary joint of the present invention can be used semi-permanently, as well as to reduce the leakage of fluid as well as to reduce the cost, has excellent cooling effect, and because it is not a complicated structure as conventional, the need for breakdown and repair There is no advantage.
