Description

워터씰{THE WATER SEAL}Water Seal {THE WATER SEAL}

본 발명은 회전되는 축과 회전되지 않는 하우징 등의 물체 사이에 누수가 발생되는 것을 방지하기 위한 워터씰에 관한 것이다.
The present invention relates to a waterseal for preventing leakage from occurring between an object such as a rotating shaft and a non-rotating housing.

물체와 물체 사이로 오일이 새어나오는 것을 방지(누유방지)하거나 물이 새어나오는 것을 방지(누수방지)하기 위해서 각종 씰이 안출되었다.Various seals have been devised to prevent oil from leaking between objects (leakage prevention) or to prevent water leakage (leakage).

일반적으로 오일이 새어나오는 것을 방지하기 위한 씰을 '오일씰'이라고 하고, 물이 새어나오는 것을 방지하기 위한 씰을 '워터씰'이라고 한다.Generally, a seal for preventing oil from leaking is called an 'oil seal', and a seal for preventing water from leaking is called a 'water seal'.

워터씰은 사용환경과 적용분야에 따라 다양한 형태의 것이 안출되어 있는데 고속회전이 이루어지는 회전축(4)과 회전되지 않는 하우징(5) 사이에 설치되는 워터씰은 탄성력을 갖지 않는 물체(부품)를 밀착시켜 누수를 방지하는 메케니컬(Mechanical) 방식의 것을 사용하고 있었다. Water seals come in various forms depending on the use environment and application fields. Water seals installed between the rotating shaft 4 and the non-rotating housing 5 that rotate at high speed adhere closely to objects (parts) having no elastic force. The mechanical type that prevents water leakage was used.

구체적인 예로 설명하면, 차량 등에 구비되는 워터펌프에서 고속으로 회전하는 회전축과 비회전체인 워터펌프의 하우징 사이로 누수가 발생되는 것을 방지하기 위해 메케니컬 방식의 워터씰을 사용하고 있었다.As a specific example, a mechanical seal was used to prevent water leakage between the rotating shaft rotating at high speed and the housing of the non-rotating water pump in a water pump provided in a vehicle.

그런데 메케니컬 방식은 도 1과 같이 탄성력을 갖지 않는 제1실링몸체(1)와 제2실링몸체(2))를 밀착시켜 누수방지 효과를 얻는 것이기 때문에 그 효과가 기대에 미치지 못하였다. However, since the mechanical method is to close the first sealing body (1) and the second sealing body (2) having no elastic force as shown in Figure 1 to obtain a leakage preventing effect, the effect did not meet expectations.

실제적으로 미량의 누수가 발생되는 경우가 많으나 이를 허용하면서 사용하고 있는 실정이다. Actually, a small amount of water leakage is often generated, but this situation is being used while allowing this.

메커니컬 방식의 또 다른 문제점은, 마모현상에 대응되도록 하고 있으나 마모현상 자체를 방지하는 것이 아니기 때문에 빠르게 진행되는 마모현상에 의한 내구성 취약의 문제점이 있다는 것이었다.(스프링과 벨로우즈 형상의 고무(3)를 사용하여 마모에 대응되도록 하고 있음)Another problem with the mechanical method is that it is intended to cope with the wear phenomenon, but it does not prevent the wear phenomenon itself, so there is a problem of weak durability due to the rapid progress of the wear phenomenon (spring and bellows-shaped rubber 3). To cope with wear)

또, 많은 부품(9개 이상)으로 이루어질 뿐만 아니라 복잡한 구조를 갖기 때문에 제조 원가가 상당히 높은 문제점도 있었다.
In addition, the manufacturing cost is also very high because it consists of a large number of components (more than nine) and has a complicated structure.

본 발명은 상기와 같은 문제점을 해소하려는 것으로서, 더욱 상세하게는 누수 방지효과가 우수할 뿐만 아니라 내구성도 우수하고 제조원가도 매우 저렴한 구조를 가지는 워터씰을 제공하려는데 목적이 있다.
The present invention aims to solve the above problems, and more particularly, to provide a water seal having a structure that is excellent in preventing leakage and excellent in durability and very low in manufacturing cost.

본 발명에서는 축이 삽입되어 회전되는 내경형성몸체와 회전되지 않는 외부형성몸체에 의해 실링재설치공간이 형성되도록 하고, 상기 실링재설치공간에 위치되어 있고 내경형성몸체에 밀착되는 제1립과 외부형성몸체에 밀착되는 제2립을 갖는 고무립형성몸체를 통해 누수를 방지한다.In the present invention, the sealing member installation space is formed by the inner diameter forming body and the outer forming body is not rotated by the shaft is inserted, the first lip and the outer forming body located in the sealing mounting space and in close contact with the inner diameter forming body Leakage is prevented through the rubber lip forming body having a second lip in close contact.

또, 고무립형성몸체의 제1립 주변에 그리스 등의 윤활제를 위치시켜 립의 마모를 방지하고, 제1립의 마모에 대응할 수 있는 탄성체를 구비한다.In addition, a lubricant such as grease is placed around the first lip of the rubber lip forming body to prevent abrasion of the lip, and an elastic body that can cope with abrasion of the first lip is provided.

이를 통해 누수 방지효과가 우수할 뿐만 아니라 내구성도 우수하고 제조 원가도 매우 저렴한 구조를 가지는 워터씰이 되도록 한다.Through this, not only the water leakage effect is excellent, but also the durability and manufacturing cost of water seal having a very low cost structure.

또, 어느 한쪽은 고무립형성몸체에 밀착되고 다른 한쪽은 내경형성몸체에 밀착되며 제1립과 내경형성몸체 주변의 물 사이에 위치되고, 내경형성몸체 주변에 위치되는 물의 압력에 견딜 수 있는 재질로 구현되어 물이 내경형성몸체와 외경형성몸체의 사이로 누수되는 것을 방지하면서 물의 압력이 제1립에 가해지는 것을 방지하는 마모방지몸체를 구비하여 물의 압력에 대응하면서 제1립이 빠르게 마모되는 것이 방지되도록 한다. In addition, one side is in close contact with the rubber lip forming body, the other is in close contact with the inner diameter forming body and positioned between the water around the first lip and the inner diameter forming body, the material capable of withstanding the pressure of the water located around the inner diameter forming body It is implemented to have a wear-resistant body that prevents water from being applied to the first lip while preventing water from leaking between the inner diameter-forming body and the outer diameter-forming body that the first lip wears quickly while responding to the water pressure To prevent it.

이러한 본 발명의 워터씰은, 회전축이 삽입되는 회전축삽입홀이 형성되고 삽입된 회전축과 함께 회전되는 환형의 내경형성몸체를 갖는다. The water seal of the present invention, the rotation shaft insertion hole is formed is a rotation shaft is inserted and has an annular inner diameter forming body that is rotated with the inserted rotation shaft.

또, 내경형성몸체의 외측에 위치되어 있되 내경형성몸체와의 사이에 실링재설치공간을 형성하도록 위치되어 있고, 하우징에 설치되어 고정되는 외부형성몸체를 갖는다.In addition, it is located on the outside of the inner diameter forming body, and positioned to form a sealing material installation space between the inner diameter forming body, and has an outer forming body which is installed and fixed to the housing.

또, 실링재설치공간에 위치되고 내경형성몸체에 밀착되는 제1립과 외부형성몸체에 밀착되는 제2립을 통해 물이 내경형성몸체와 외경형성몸체의 사이로 누수되는 것을 방지하는 고무재질의 고무립형성몸체를 갖는다.In addition, the rubber granules of rubber material to prevent water from leaking between the inner diameter forming body and the outer diameter forming body through the first lip located in the sealing material installation space and in close contact with the inner diameter forming body and the second lip contacting the outer forming body. Have a body formed.

또, 고무립형성몸체의 제1립이 내경형성몸체에 밀착되도록 고무립형성몸체를 내경형성몸체 방향으로 밀어주는 탄성체를 갖는다. Further, the rubber lip forming body has an elastic body for pushing the rubber lip forming body toward the inner diameter forming body so that the first lip of the rubber lip forming body comes into close contact with the inner diameter forming body.

또, 고무립형성몸체의 제1립 주변에 위치된 윤활유를 갖는다.
It also has lubricating oil located around the first lip of the rubber lip forming body.

본 발명의 워터씰은, 회전축이 삽입되어 회전되는 내경형성몸체와 회전되지 않는 외부형성몸체에 의해 실링재설치공간이 형성되고, 상기 실링재설치공간에 위치되어 있으며 내경형성몸체에 밀착되는 제1립과 외부형성몸체에 밀착되는 제2립을 갖는 고무립형성몸체를 통해 누수를 방지한다.The water seal of the present invention is a sealing member installation space is formed by the inner diameter forming body that is rotated by the rotation shaft is inserted and the outer forming body that is not rotated, is located in the sealing material installation space and is in close contact with the inner diameter forming body and Leakage is prevented through the rubber lip forming body having a second lip in close contact with the external forming body.

또, 고무립형성몸체의 제1립 주변에 그리스 등의 윤활제가 위치되어 제1립의 마모가 방지되고, 제1립이 마모되더라도 탄성체에 의해서 제1립이 내경형성몸체에 밀착됨으로써 제1립의 마모가 진행되더라도 누수방지 기능이 온전히 수행되도록 한다.In addition, a lubricant such as grease is placed around the first lip of the rubber lip forming body to prevent wear of the first lip, and even if the first lip is worn, the first lip is in close contact with the inner diameter forming body by the elastic body.

이하, 본 발명의 기술적 사상을 첨부된 도면을 사용하여 더욱 구체적으로 설명한다.Hereinafter, the technical spirit of the present invention will be described in more detail with reference to the accompanying drawings.

그러나 첨부된 도면은 본 발명의 기술적 사상을 더욱 구체적으로 설명하기 위하여 도시한 일 예에 불과하므로 본 발명의 기술적 사상이 첨부된 도면의 형태에 한정되는 것은 아니다.It is to be understood, however, that the appended drawings illustrate only typical embodiments of the present invention and are not to be considered as limiting the scope of the invention.

본 발명은 고속 회전되는 회전축과 회전되지 않는 하우징 등의 물체 사이에 누수가 발생되는 것을 방지하기 위한 워터씰에 관한 것이다.The present invention relates to a water seal for preventing leakage between an object such as a rotating shaft that rotates at a high speed and a non-rotating housing.

따라서 본 발명의 워터씰은, 회전축(4)이 삽입되는 회전축삽입홀(11)이 형성되고 삽입된 회전축(4)과 함께 회전되는 내경형성몸체(10)를 갖는다.Accordingly, the water seal of the present invention has an inner diameter forming body 10 in which a rotating shaft insertion hole 11 into which the rotating shaft 4 is inserted is formed and rotates together with the inserted rotating shaft 4.

또, 내경형성몸체(10)의 외측에 위치되어 있되 내경형성몸체(10)와의 사이에 실링재설치공간(30)을 형성하도록 위치되어 있고, 하우징(5)에 설치되어 고정되는 외부형성몸체(20)를 갖는다.(상기 설명에서 하우징이란 회전되지 않는 물체를 의미한다.)In addition, the outer forming body 20 which is located outside the inner diameter forming body 10 is positioned to form a sealing material installation space 30 between the inner diameter forming body 10, and is installed and fixed to the housing (5). (In the above description, the housing means an object that does not rotate.)

상기와 같은 내경형성몸체(10)와 외부형성몸체(20)는 워터씰 분야에서 이미 공지된 것이고, 사용환경 등에 따라 다양한 형태로 구현되는 것이므로 이 부분에 대한 구체적인 설명은 생략한다. The inner diameter forming body 10 and the outer forming body 20 as described above are already known in the field of water seal, and since it is implemented in various forms according to the use environment, a detailed description thereof will be omitted.

그런데 본 발명은 종래의 메케니컬 방식의 워터씰과 달리 누수 방지효과가 우수할 뿐만 아니라 내구성도 우수하고 제조 원가도 매우 저렴한 구조를 가지는 워터씰을 제공하려는 목적을 갖는다.However, the present invention has an object to provide a water seal having a structure that is excellent in durability and excellent in durability and low in manufacturing cost, unlike the conventional mechanical seal.

이를 위하여 본 출원의 발명자는 통상의 오일씰과 같이 립을 통해 누수를 방지하는 구조를 안출하였다.To this end, the inventors of the present application devised a structure to prevent leakage through the lip like a conventional oil seal.

구체적으로 설명하면 본 발명의 워터씰은, 실링재설치공간(30)에 위치되고 내경형성몸체(10)에 밀착되는 제1립(41)과 외부형성몸체(20)에 밀착되는 제2립(42)을 통해 내경형성몸체(10)와 외부형성몸체(20)의 사이로 누수가 발생되는 것을 방지하는 고무재질의 고무립형성몸체(40)를 갖는다.Specifically, the water seal of the present invention is located in the sealing material installation space 30 and the first lip 41 in close contact with the inner diameter forming body 10 and the second lip 42 in close contact with the outer forming body 20. It has a rubber lip forming body 40 of the rubber material to prevent the leakage occurs between the inner diameter forming body 10 and the outer forming body 20 through the).

그런데 단순히 상기와 같은 구조만으로는 내구성이 너무 취약하여 고속회전되는 회전축(4)과 하우징(5)의 사이에 설치하여 사용하는 것이 불가능하다. However, it is impossible to install and use between the rotating shaft 4 and the housing 5 which are rotated at a high speed because the durability is too weak simply by the above structure.

이것은 제1립(41)이 고속회전되는 내경형성몸체(10)에 접촉되기 때문에 마모가 매우 빠르게 진행될 수 있기 때문이다.This is because the wear can proceed very quickly because the first lip 41 is in contact with the inner diameter forming body 10 which rotates at a high speed.

이를 방지하기 위하여 본 출원의 발명자는 고무립형성몸체(40)의 제1립(41) 주변에 그리스(Grease) 등의 윤활유를 위치시키는 구조를 안출하였다.In order to prevent this, the inventor of the present application devised a structure in which lubricating oil such as grease is placed around the first lip 41 of the rubber lip forming body 40.

상기와 같은 윤활유는 본 발명의 워터씰을 조립할 때 제1립(41)이나 내경형성몸체(10) 중 제1립(41)이 접촉되는 부분에 도포해 놓은 형태의 것일 수 있다. The lubricating oil as described above may be in the form of being applied to a portion of the first lip 41 or the inner diameter forming body 10 in contact with the first seal 41 when assembling the water seal of the present invention.

물론, 바람직한 것은 제1립(41) 주변의 윤활유충진공간(12)에 윤활유가 채워져 있는 것이다.Of course, it is preferable that the lubricating oil is filled in the lubricating oil filling space 12 around the first lip 41.

첨부된 도면에서는 제1립(41)이 복수 개 형성되어 있고 어느 하나의 제1립(41)과 또 다른 제1립(41) 사이에 윤활유충진공간(12)이 형성되어 있다. In the accompanying drawings, a plurality of first lips 41 are formed, and a lubricating oil filling space 12 is formed between any one of the first lips 41 and the other first lips 41.

또, 도 2에서는 제1립(41)과 후술하는 마모방지몸체(50)의 사이에도 윤활유충진공간(12)이 형성되어 있다. In FIG. 2, the lubricating oil filling space 12 is formed between the first lip 41 and the wear preventing body 50 described later.

그런데 상기와 같은 윤활유를 제1립(41) 주변에 위치시키더라도 제1립(41)의 마모가 원천적으로 방지되는 것은 아니다. However, even if the lubricating oil as described above is located around the first lip 41, wear of the first lip 41 is not prevented at the source.

따라서 내구성 향상을 위해서는 제1립(41)의 마모에 적절히 대응하여 제1립(41)이 마모되더라도 누수방지 효과가 유지되도록 하는 수단이 필요하다.Therefore, in order to improve durability, a means for maintaining the leakage preventing effect is required even if the first lip 41 is worn in correspondence with the wear of the first lip 41 properly.

이를 위하여 본 발명에서는 고무립형성몸체(40)의 제1립(41)이 내경형성몸체(10)에 밀착되도록 고무립형성몸체(40)를 내경형성몸체(10) 방향으로 밀어주는 스프링 등의 탄성체(60)를 구비한다. To this end, in the present invention, such as a spring for pushing the rubber lip forming body 40 in the direction of the inner diameter forming body 10 such that the first lip 41 of the rubber lip forming body 40 is in close contact with the inner diameter forming body 10. An elastic body 60 is provided.

즉, 탄성체(60)가 고무립형성몸체(40)를 내경형성몸체(10) 방향으로 밀어줌으로써 제1립(41)의 마모에 적절히 대응되도록 하는 것이다.That is, the elastic body 60 pushes the rubber lip forming body 40 in the direction of the inner diameter forming body 10 so as to correspond appropriately to the wear of the first lip 41.

그런데 상기와 같은 구조만으로는 워터씰이 설치되는 장소에 위치된 물이 강한 압력을 갖는 경우에 제1립(41)의 변형 등이 발생되어 누수방지 기능을 온전히 수행할 수 없는 경우도 발생할 수 있다.By the way, only the structure as described above may occur when the water located in the place where the water seal is installed has a strong pressure, such as deformation of the first lip 41 can not fully perform the leak prevention function.

또, 윤활유를 통해 제1립(41)의 마모를 방지하더라도 윤활유를 통한 마모현상의 방지에는 한계가 있다.In addition, even if the wear of the first lip 41 is prevented through the lubricating oil, there is a limit in the prevention of wear through the lubricating oil.

따라서 물의 압력이 제1립(41)에 가해지는 것을 방지하면서 제1립(41)의 마모를 방지할 수 있는 마모방지몸체(50)를 구비하는 것이 바람직하다. Therefore, it is preferable to provide a wear preventing body 50 which can prevent the wear of the first lip 41 while preventing the pressure of the water from being applied to the first lip 41.

이러한 마모방지몸체(50)는 어느 한쪽이 고무립형성몸체(40)에 밀착되고 다른 한쪽이 내경형성몸체(10)에 밀착되며 제1립(41)과 내경형성몸체(10) 주변의 물 사이에 위치되는 형태가 된다. The wear-resistant body 50 is one of which is in close contact with the rubber lip forming body 40 and the other is in close contact with the inner diameter forming body 10 between the first lip 41 and the water around the inner diameter forming body 10 Will be in the form of.

또, 내경형성몸체(10) 주변에 위치되는 물의 압력에 견딜 수 있는 재질로 구현된다. In addition, the inner diameter forming body 10 is implemented with a material that can withstand the pressure of the water located around.

즉, 물이 내경형성몸체(10)와 외부형성몸체(20)의 사이로 누수되는 것을 방지하면서 물의 압력이 제1립(41)에 직접 가해지는 것을 방지하는 것이다.That is, the water pressure is prevented from being applied directly to the first lip 41 while preventing water from leaking between the inner diameter forming body 10 and the outer forming body 20.

상기와 같은 마모방지몸체(50)는 다양한 재질로 구현될 수 있지만 내마모성이 우수한 플루오로수지(fluororesin)로 구현되는 것이 바람직하며, 플루오르수지의 대표적인 수지인 폴리테트라플루오로에틸렌(PTFE)이 가공성 등의 여러 가지 사항을 고려할 때 가장 바람직하다.The wear-resistant body 50 as described above may be implemented in a variety of materials, but is preferably implemented as a fluororesin (fluororesin) having excellent wear resistance, and polytetrafluoroethylene (PTFE), which is a typical resin of fluororesin, may be processed. This is most desirable when considering several things.

상기 설명에서 마모방지몸체(50)가 내경형성몸체(10) 주변에 위치되는 물의 압력에 견딜 수 있다는 의미는 압력에 파손되지 않으며 그 기능을 수행할 수 없을 정도로 변형되지 않는다는 것을 의미한다.In the above description, the wear-resistant body 50 can withstand the pressure of the water located around the inner diameter forming body 10, which means that the pressure is not broken and does not deform to the extent that it cannot perform its function.

상기와 같은 마모방지몸체(50)는 도 2와 같이 내경형성몸체(10)와 선접촉되도록 할 수도 있고 도 4와 같이 면접촉되도록 할 수도 있다.The wear preventing body 50 as described above may be in line contact with the inner diameter forming body 10 as shown in Figure 2 or may be in surface contact as shown in FIG.

마모방지몸체(50)가 내경형성몸체(10)와 면접촉되는 경우에는 마모방지 효과가 우수한 장점이 있지만 누수방지 기능이 우수하도록 하기 위해서는 접촉면이 매우 평탄하게 가공되어야 하는 단점이 있다.When the anti-wear body 50 is in surface contact with the inner diameter forming body 10, the wear-prevention effect is excellent, but the contact surface must be processed to be very flat in order to have an excellent anti-leakage function.

반면, 마모방지몸체(50)가 내경형성몸체(10)와 선접촉되는 경우에는 마모방지 효과는 다소 저하되지만 접촉면이 최소화되기 때문에 우수한 누수방지 효과를 얻을 수 있는 장점이 있다.
On the other hand, when the anti-wear body 50 is in line contact with the inner diameter forming body 10, the anti-wear effect is somewhat lowered, but because the contact surface is minimized, there is an advantage to obtain an excellent leak prevention effect.

본 발명의 구성요소인 제1립(41)이나 제2립(42)은 복수 개 형성되어 있는 것이 바람직하다. It is preferable that the 1st lip 41 and the 2nd lip 42 which are components of this invention are formed in multiple numbers.

이러한 경우 어느 하나의 제1립(41)이나 제2립(42)이 누수방지 기능을 온전히 수행하지 못하는 경우에 또 다른 제1립(41)이나 제2립(42)이 누수방지 기능을 온전히 수행할 수 있어 안전한 특징이 있다.
In this case, when either one of the first lips 41 or the second lips 42 does not fully perform the leakage preventing function, the other first lips 41 or the second lips 42 completely perform the leakage preventing function. It is safe to carry.

본 발명의 워터씰이 설치될 때 하우징(5)과 외부형성몸체(20)의 외주면 사이에 틈새가 발생되어 누수가 발생되는 것을 방지할 수 있도록 외부형성몸체(20)에 라텍스 코팅을 실시할 수 있다.When the water seal of the present invention is installed, a gap is generated between the housing 5 and the outer circumferential surface of the outer forming body 20 so that latex coating may be applied to the outer forming body 20 to prevent leakage. have.

즉, 탄성을 갖는 라텍스가 코팅되어 있어 하우징(5)과 외부형성몸체(20)가 매우 견고하게 밀착되고 이로 인해 하우징(5)과 외부형성몸체(20)의 사이로 누수가 발생되는 것을 방지하는 것이다.That is, the latex is coated with elasticity so that the housing 5 and the external forming body 20 are tightly adhered to each other, thereby preventing leakage between the housing 5 and the external forming body 20. .
