본 발명은 밀폐가 보다 완벽하면서 기계작동시의 마찰 저항이 적도록한 밀폐용 패킹에 관한 것이다.The present invention relates to a seal for sealing which makes the seal more perfect and has less frictional resistance during machine operation.
종래의 패킹은 단순히 고무의 탄성에만 의존한 것이었기 때문에 각종 공압 또는 유압기기의 회전체나 미끄럼체에 사용할 경우 밀폐가 잘되도록 죄임력을 강하게 하면 밀폐능력은 좋으나 회전체의 회전 또는 미끄럼체의 미끄럼운동에 대한 저항이 높아 기계작동이 부드럽지 못하고 패킹의 마모율이 높아 적시에 교환해주지 못하면 쉽게 누설이 되는 문제가 있었다.Conventional packing was simply dependent on the elasticity of rubber, so when it is used for rotating or sliding bodies of various pneumatic or hydraulic equipments, if the clamping force is strong to ensure good sealing, the sealing ability is good, but the rotating or sliding body of the rotating body is slippery. High resistance to movement, the machine operation is not smooth, and the wear rate of the packing is high, if there is a problem that can not be easily replaced in time to leak.
또 이러한 종래의 패킹은 고압기기인 경우 밀폐력을 높게하기 위하여 죄임력을 강하게 하기 때문에 기계조립시나 패킹 교환시에 패킹을 끼우거나 빼내는 작업이 매우 힘들고 어려운 문제도 있다.In addition, such a conventional packing has a very difficult and difficult problem of inserting or removing the packing when assembling the machine or replacing the packing because the clamping force is strengthened to increase the sealing force in the case of high pressure equipment.
본 발명과 비슷한 패킹으로서는 제4도에 도시된 바와 같이 패킹의 몸체(20) 위에 "V"형 날개편(21)을 형성한 것이 있었다.As a packing similar to the present invention, as shown in FIG. 4, a "V" shaped wing piece 21 was formed on the body 20 of the packing.
이러한 패킹은 내부의 공압이나 유압이 일차적으로 날개편(21)에 의하여 차단되고 다시 몸체(20)의 밀착력에 의하여 차단되므로 밀폐효과가 높고 날개편(21)은 내부압이 강할수록 더욱 확개되어 강하게 밀착되므로서 밀폐도가 더 높아지는 장점이 있는 것이었다.Since the packing is primarily blocked by the pneumatic or hydraulic pressure by the wing piece 21 and again by the adhesive force of the body 20, the sealing effect is high and the wing piece 21 is more expanded and stronger as the internal pressure is stronger. There was an advantage that the tightness is more tightly.
그러나 이러한 패킹의 날개편(21)은 그 상단부가 얇기때문에 밀착되는 면과 사이에 이물질이 끼어들거나 또는 밀착되는 면이 매끈하지 못하고 거칠때에는 그사이에 미세한 틈이 생기게 되고 이 틈은 내부압이 기름이나 물과 같은 액체일 경우에는 유막이나 수막이 형성되어 누설이 방지될 수도 있으나 공기나 깨스일때는 쉽게 그 틈사이로 누설이 되는 것이다.However, the wing piece 21 of the packing is thin because the upper end portion is thin and foreign matter is inserted between the contact surface or the contact surface is not smooth and when a rough surface there is a fine gap between the gap and the internal pressure is oil or In the case of a liquid such as water, an oil film or a water film may be formed to prevent leakage, but when it is air or cracks, it is easily leaked between the gaps.
따라서 이러한 날개편이 있는 패킹 역시 고무의 탄성에만 의존하는 것은 마찬가지이고 밀폐력을 높게하기 위하여서는 몸체(20) 부분의 죄임력을 강하게 하여야 하기 때문에 고압기기인 경우 저항과 마찰이 심하여 작동이 부드럽지 못하고 패킹의 마모율이 높아 자주 교환해주어야하며 패킹의 삽탈작업도 힘이 드는 등의 문제가 있는 것이었다.Therefore, such a winged packing also depends solely on the elasticity of the rubber, and in order to increase the sealing force, the clamping force of the body 20 must be strengthened. Therefore, in the case of a high-pressure device, the resistance and friction are high and the operation is not smooth. The wear rate was high, so frequent replacement was required, and the removal of the packing was also difficult.
또 일본공개실용신안 소54-176062호와 같이 패킹내부에 일측이 개방된 공간부가 형성되고 공간부의 개방부쪽에 돌출부가 형성되어 이 돌출부가 실린더 내벽에 접하도록 한것도 있었으나 이러한 패킹은 몸체와 돌출부에 의한 이중밀폐가 되지 못하고 돌출부에 의하여서만 되므로 밀폐력이 떨어지는 것일뿐아니라 내부압이 강해지면 실린더 내벽과 접한 돌출부가 내부압에 의하여 공간부쪽으로 밀려 들어가 실린더 내벽과 떨어지므로 밀폐력이 더욱 저하되는 등의 문제가 있는 것이었다.In addition, as shown in Japanese Utility Model Application No. 54-176062, there was a space in which one side was opened, and a protrusion was formed in the opening of the space, so that the protrusion was in contact with the inner wall of the cylinder. Not only double sealing, but only by the protrusion, so that the sealing force is not only lowered, but when the internal pressure becomes stronger, the protrusion contacting the inner wall of the cylinder is pushed toward the space by the inner pressure and falls off from the inner wall of the cylinder. It was.
본 발명은 이러한 제반 문제점을 해결하기 위하여 상부에는 좌우로 벌어지는 날개편을 형성하고 몸체내에는 팽창실을 형성하여 내부압이 가해지면 몸체가 팽창하면서 날개편도 더욱 벌어지도록 한 것이다.In order to solve the above problems, the present invention is to form a wing piece that extends to the left and right in the upper portion and an expansion chamber in the body so that the wing piece is further opened while the body expands when an internal pressure is applied.
이경우 중요한 것은 몸체가 팽창할때 몸체 상부에 형성된 날개편의 하부가 같이 확개되지 않도록 하는 것이다.In this case, it is important to prevent the lower part of the wing piece formed on the upper part of the body from expanding as it expands.
왜냐하면 몸체가 팽창되면서 날개편의 하부도 같이 확개되면 상대적으로 날개편 상부의 확개력이 부족해지기 때문에 밀폐효과가 반감된다.Because when the body is expanded and the lower part of the wing piece is also expanded, the expansion force of the upper part of the wing piece is relatively insufficient, so the sealing effect is halved.
이러한 문제를 해결하기 위하여 본 발명에서는 날개편과 몸체사이에 얇은 주름을 형성하므로서 몸체가 팽창되어도 날개편 하부는 따라 움직이지 않도록 하였다.In order to solve this problem, in the present invention, a thin wrinkle is formed between the wing piece and the body so that the lower wing piece does not move even when the body is expanded.
본 발명에서 몸체의 팽창으로 패킹의 밀착력이 높아져도 기계의 작동이 부드럽고 패킹의 마모율이 낮은 이유는 다음과 같다.In the present invention, even if the adhesion of the packing is increased by the expansion of the body, the operation of the machine is soft and the wear rate of the packing is low as follows.
즉 모든 회전체나 미끄럼체는 회전운동이나 왕복운동을 할때 진동이 전혀 없는 완벽한 원운동이나 직선운동을 하지는 못하고 다소간 진동하면서 회전하거나 왕복운동을 한다.That is, all the rotating bodies or sliding bodies do not have perfect circular motion or linear motion without any vibration when rotating or reciprocating.
따라서 작동되는 회전체나 미끄럼체를 둘러싸고 있는 패킹의 죄임력이 같다해도 진동에 따라 진동되는 방향으로 부드럽게 팽축해주는 것이 팽축이 부드럽지 못한 것보다 저항과 마찰이 적어 기계작동이 부드럽고 패킹의 마모율도 낮아지는 것이다.Therefore, even though the clamping force of the rotating body or the sliding body surrounding the sliding body is the same, the expansion and smoothing in the direction vibrating with vibration is less resistance and friction than the expansion is not smooth. To lose.
본 발명의 패킹은 일본공개실용신안 소54-176062호와 달리 몸체내의 팽창실을 내부압이 지지해주므로 몸체의 두께가 얇아도 필요한 밀착력을 갖는다.The packing of the present invention, unlike Japanese Patent Application Laid-Open No. 54-176062, has internal pressure supported by the expansion chamber in the body, and thus has the necessary adhesion even if the thickness of the body is thin.
따라서 몸체의 두께를 얇게 할 수가 있고 몸체의 두께가 얇은 팽창실은 회전체 등의 작동시에 진동에 따른 진동방향으로의 팽축이 보다 섬세하고 부드럽게 이루어지므로 저항과 마찰이 적은 것이다.Therefore, the thickness of the body can be made thin and the expansion chamber with a thin thickness of the body has less resistance and friction since the expansion in the vibration direction is made more delicately and smoothly according to the vibration during operation of the rotating body.
본 발명의 실시예를 첨부도면에 따라 상세히 설명하면 다음과 같다.An embodiment of the present invention will be described in detail with reference to the accompanying drawings.
탄성체로된 패킹(1)의 몸체(2) 양측에 윗쪽이 개방된 팽창실(3)(3')을 형성하고 몸체(2) 상측에 양쪽으로 벌어진 날개편(4)(4')을 형성하되 날개편(4)(4')과 몸체(2)사이에 쉽게 절첩되도록 얇고 질긴 주름(5)(5')을 형성하여서된 것이다.On both sides of the body 2 of the packing 1 made of an elastic body, an expansion chamber 3, 3 ′ having an open upper side is formed, and wing pieces 4, 4 ′ formed on both sides above the body 2. However, it is to form a thin and tough wrinkles (5) (5 ') so as to be easily folded between the wing piece (4) (4') and the body (2).

(14)(14')는 몸체의 밀착부분이다.(14) (14 ') is the close part of the body.
이와 같이 구성된 본 발명의 패킹(1)은 제2도에서와 같이 내외관체(10)(11) 사이에 끼워 사용하는 것은 종래와 같으나 내부압이 가하여지면 제3도에서와 같이 날개편(4)(4')이 좌우로 확개되어 외부관체(10)에 밀착되고 팽창실(3)(3')이 팽창되어 더욱 밀착된다.The packing 1 of the present invention configured as described above is inserted and used between the inner and outer shells 10 and 11 as shown in FIG. 2, but when the inner pressure is applied, the wing piece 4 as shown in FIG. 4 'is expanded to the left and right to be in close contact with the outer tube 10, and the expansion chambers 3 and 3' are expanded to be in close contact with each other.
따라서 내부의 기름이나 공기등이 외부로 밀고 나오려는 힘이 강할수록 날개편(4)(4')이 더욱 확개되어 밀착력이 강해지고 밀착부분이 넓어질뿐아니라 몸체(2)도 더욱 팽창하여 밀착력과 밀착부분(14)(14')이 넓어지기 때문에 밀폐능력이 뛰어나면서 날개편(4)(4')의 단부가 매우 얇고 몸체(2)내에 두께가 얇은 팽창실(3)(3')이 형성되어 있어 회전 또는 왕복 운동시에 그에 따른 진동에 보다 섬세하고 부드럽게 대응하여 팽축하므로 저항과 마찰이 적어 기계의 작동이 부드럽고 패킹(1)의 마모율이 낮아 자주 교환해 주지 않도록 누설의 우려가 없는 등의 작용효과가 있는 것이다.Therefore, the stronger the force to push out of the oil or air to the outside, the more the wing pieces (4) (4 ') are expanded, resulting in stronger adhesion and wider contact, as well as the expansion of the body (2). And the close contact portions 14, 14 'are wider, so that the end portions of the wing pieces 4, 4' are very thin and the thickness of the expansion chambers 3, 3 'in the body 2 is excellent. Since it is formed, it expands more delicately and smoothly in response to vibration during rotation or reciprocation, and it has less resistance and friction, so the operation of the machine is smooth, and the wear rate of the packing (1) is low. There is no effect such as not.
또 두께가 얇은 팽창실(3)(3') 때문에 패킹(1)의 팽축이 용이하고 팽축범위도 넓어 기계 조립시나 패킹(1) 교환시에 벗겨내고 끼우기가 매우 쉽게 된다.In addition, the thinner expansion chambers (3) and (3 ') make it easier to squeeze the packing (1) and have a wider range of squeezing.
