구름베어링의 시일링장치{an apparatus for sealing a rolling bearing}Sealing device for rolling bearings {an apparatus for sealing a rolling bearing}

본 발명은 구름베어링에 관한 것으로서, 보다 상세하게는 구름베어링의 시일링장치에 관한 것이다.The present invention relates to rolling bearings, and more particularly to a sealing device for rolling bearings.

자동차용, 농업용 및 산업용 엔진의 냉각시스템에 사용되는 구름베어링(특히 펌프용 구름베어링)등은 종래 도1에 도시한 바와 같이, 내륜(2)과 외륜(4) 사이에 다수의 구름체(6)가 배열되고, 상기 다수의 구름체(6)를 소정의 간격으로 유지시키도록 리테이너(8)가 결합되며, 상기 내륜(2)과 외륜(4)의 사이에 형성된 공간(S)의 개구단부에는 이 공간(S)으로 이물질이 유입되지 않게 하도록 밀봉시일(10)이 결합되어 있다.Rolling bearings (particularly pump rolling bearings) used in cooling systems for automobiles, agricultural and industrial engines, and the like, are conventionally shown in FIG. 1, and are provided with a plurality of rolling bodies 6 between the inner ring 2 and the outer ring 4. ) Is arranged, and the retainer 8 is coupled to maintain the plurality of rolling bodies 6 at predetermined intervals, and an opening end of the space S formed between the inner ring 2 and the outer ring 4. The sealing seal 10 is coupled so that foreign matter does not flow into this space (S).

상기한 밀봉시일(10)은 냉간압연재를 소정의 형상으로 절곡하여 구성한 보강테(12)에 시일재(14)를 밀착성형시켜, 베어링 외륜(4)에 형성된 걸림홈띠(4a)에 압입 고정시키는 구조로 되어 있다.The sealing seal 10 is formed by closely sealing the sealing member 14 to the reinforcing frame 12 formed by bending the cold rolled material into a predetermined shape, and press-fitting to the locking groove 4a formed in the bearing outer ring 4. It is structure to let.

상기 시일재(14)의 내측, 즉 내륜(2)의 외면에 밀착하는 부위에는 양측으로 갈라진 제1시일립(14a) 및 제2시일립(14b)이 형성되어 있다. 상기 제1시일립(14a)은 상기 공간(S)의 내측에 형성되어 이 공간에 투입된 그리이스의 누설을 방지하는 역활을 하고, 상기 제2시일립(14b)은 상기 공간(S)의 외측에 형성되어 외부로부터 상기 공간으로 이물질 또는 수분의 혼입을 방지하는 역활을 한다.The first seal lip 14a and the second seal lip 14b which are split to both sides are formed at the inner side of the seal member 14, that is, at a portion in close contact with the outer surface of the inner ring 2. The first seal lip 14a is formed inside the space S to prevent leakage of grease injected into the space, and the second seal lip 14b is disposed outside the space S. It is formed to serve to prevent the incorporation of foreign matter or moisture into the space from the outside.

그런데, 최근에는 펌프가 사용되는 엔진의 성능이 향상되어 이에 따라 베어링의 고성능화가 점차적으로 요구되어 있으며, 이로 인해 베어링의 성능에 커다란 영향을 미치는 시일부의 밀봉성 및 이물침입방지 기능을 향상할 필요가 있다. 펌프용 베어링의 손상의 원인은 여러가지가 있으나, 그 중 그리이스 누설에 따른 윤활불량, 베어링 내 이물질 및 수분 침투가 가장 큰 원인이다. 베어링의 수명은 이러한 그리이스 누설과 베어링 내 이물질 및 수분 침투에 직접적인 관련이 있다.However, in recent years, the performance of the engine in which the pump is used is improved, and accordingly, the performance of the bearing is gradually required. As a result, it is necessary to improve the sealability of the seal portion and the foreign matter intrusion prevention function which greatly affect the performance of the bearing. have. There are many causes of damage to the bearings for pumps, but the most common causes are poor lubrication due to grease leakage, foreign substances in the bearings, and water penetration. The life of the bearing is directly related to this grease leakage and the ingress of foreign matter and water in the bearing.

종래 펌프용 베어링의 제1시일립(14a) 및 제2시일립(14b)이 그리이스의 누설 방지와 이물질 및 수분침투의 방지를 하기는 하지만, 벨트 구동시스템에서 베어링이 벨트 마모분 및 외부 이물질에 항상 노출되어 있으므로 이물질의 혼입을 충분히 방지하지 못하여 베어링을 손상케 한다는 문제점이 있었다.Although the first seal lip 14a and the second seal lip 14b of the conventional pump bearing prevent grease from leaking, and prevent foreign matter and moisture from penetrating, in the belt drive system, the bearing is exposed to belt wear and external foreign matter. Since it is always exposed, there is a problem that damage to the bearing is not enough to prevent the mixing of foreign matter.

따라서, 본 발명은 상기 문제점을 해결하기 위해 이루어진 것으로서, 본 발명의 목적은 외부로부터 베어링의 내부로 이물질의 혼입방지기능을 더욱 향상하여 베어링의 내구성을 높이는 구름베어링의 시일링장치를 제공하는데 있다.Accordingly, the present invention has been made to solve the above problems, and an object of the present invention is to provide a sealing device for rolling bearings to further enhance the durability of the bearings by further improving the prevention of mixing of foreign matter into the bearings from the outside.

이하, 본 발명의 바람직한 실시예에 관하여 첨부도면을 참조하면서 상세히 설명한다.Hereinafter, with reference to the accompanying drawings, a preferred embodiment of the present invention will be described in detail.

도2에 도시한 바와 같이, 내륜(22)과 외륜(24) 사이에는 다수의 구름체(26)가 배열되어 있고, 상기 다수의 구름체(26)는 이 구름체(26)를 감싸는 리테이너(28)에 의해 소정의 간격으로 유지되고 있다. 상기 내륜(22)과 외륜(24)의 사이에 형성된 공간(S)의 개구단부에는 이 공간(S)으로 이물질이 유입되지 않게 하도록 밀봉시일(30)이 결합되어 있다. 그리고, 상기 내륜(22)의 외면에는 단면이 ㄴ자를 이룬 보조부재(32)가 억지 끼움되어 있다.As shown in FIG. 2, a plurality of rolling bodies 26 are arranged between the inner ring 22 and the outer ring 24, and the plurality of rolling bodies 26 includes a retainer surrounding the rolling bodies 26. 28 is maintained at predetermined intervals. A sealing seal 30 is coupled to the open end of the space S formed between the inner ring 22 and the outer ring 24 to prevent foreign matter from entering the space S. And, the outer surface of the inner ring 22 is inserted into the auxiliary member 32 having a c-shaped cross section.

상기 외륜(24)의 내면 가장자리에는 상기 밀봉시일(30)이 걸리도록 걸림홈띠(24a)가 원주방향을 따라 형성되어 있다.A locking groove 24a is formed along the circumferential direction of the inner surface edge of the outer ring 24 so that the sealing seal 30 is caught.

상기 밀봉시일(30)은 냉간압연재를 소정의 형상으로 절곡하여 구성한 보강테(36)에 시일재(38)를 밀착성형시켜 상기 걸림홈띠(24a)에 압입 고정시키는 구조로 되어 있다.The sealing seal 30 has a structure in which the sealing member 38 is pressed against the reinforcing frame 36 formed by bending the cold rolled material into a predetermined shape to press-fit the fastening groove 24a.

상기 보조부재(32)는 수평플랜지(32a)와 수직플랜지(32b)가 ㄴ자를 이루고 있으며, 상기 수평플랜지(32a)의 내면은 상기 내륜의 외면에 밀착하여 고정되고, 상기 수평플랜지(32a)의 외면은 상기 밀봉시일(30)의 단부면(후술하는 제1, 제2시일립)에 접촉하며, 상기 수직플랜지(32b)는 상기 밀봉시일(30)에서 베어링의 폭방향 외측으로 소정거리 이격되어 위치하며, 상기 수직플랜지(32b)의 단부에는 상기밀봉시일 측으로 돌출된 돌출띠(32c)가 원주방향으로 형성된 구조이다. 보조부재(32)의 재질은 내식성이 뛰어난 스테인레스 강재 등으로 되어 있다.The auxiliary member 32 has a horizontal flange (32a) and the vertical flange (32b) is a letter N, the inner surface of the horizontal flange (32a) is fixed in close contact with the outer surface of the inner ring, the horizontal flange (32a) of The outer surface is in contact with the end surface (first and second seal lip described later) of the sealing seal 30, the vertical flange 32b is spaced apart a predetermined distance from the sealing seal 30 to the outside in the width direction of the bearing Located in the end portion of the vertical flange 32b is a structure in which the protruding band 32c protruding toward the sealing seal is formed in the circumferential direction. The auxiliary member 32 is made of stainless steel or the like having excellent corrosion resistance.

상기 수직플랜지(32b)의 상단과 상기 외륜의 내면사이에는 소정의 간격이 형성되어 트여 개구부(C)를 이루도록 수직플랜지(32b)의 폭은 밀봉시일(30)의 폭보다 작게 되어 있다.A predetermined gap is formed between the upper end of the vertical flange 32b and the inner surface of the outer ring to form an opening C so that the width of the vertical flange 32b is smaller than the width of the sealing seal 30.

상기 보강테(36)는 상기 시일재(38)의 내측에 위치하고 있는데, 그 상부는 구부려져서 시일재(38)의 상부에 박히는 형상으로 되어 있고, 그 하부는 상기 시일재(38)의 후술하는 보강부측으로 구부려져 시일재에 박혀 있다.The reinforcing frame 36 is located inside the seal member 38, the upper portion of which is bent to be embedded in the upper portion of the sealing member 38, and the lower portion thereof is described later in the sealing member 38. It is bent to the reinforcement side and embedded in the sealing material.

상기 시일재(38)는 상기 걸림홈띠(24a)에 걸리는 머리부에서 하측으로 절곡되면서 연장되어 그 하단에 제1, 제2시일립(38a)(38b)이 형성된 구조이다. 상기 제1, 제2시일립(38a)(38b)은 상기 수평플랜지(32a)의 외면에 밀착하게 되어 있다. 상기 시일재(38)의 재질은 고무로 되어 있으나, 다양한 종류의 합성수지를 사용할 수도 있다.The seal member 38 has a structure in which the first and second seal lips 38a and 38b are formed at the lower end thereof while being extended downward while being bent downward from the head caught by the locking groove 24a. The first and second seal lips 38a and 38b are in close contact with the outer surface of the horizontal flange 32a. The seal material 38 is made of rubber, but various kinds of synthetic resins may be used.

상기 제1시일립(38a)은 베어링의 내측으로 벌어져 그 단부면이 상기 보조부재(32)의 수평플랜지(32a) 내면에 밀착하여 있고, 상기 제2시일립(38b)는 베어링의 외측으로 벌어져 그 단부면이 상기 보조부재(32)의 수평플랜지(32a) 내면에 밀착하고 있다. 상기 제1, 제2시일립(38a)(38b)이 합쳐진 부분 상측에는 베어링의 내측으로 돌출된 보강부(38c)가 형성되어 있다.The first seal lip 38a is opened to the inner side of the bearing and its end face is in close contact with the inner surface of the horizontal flange 32a of the auxiliary member 32, and the second seal lip 38b is opened to the outside of the bearing. The end face is in close contact with the inner surface of the horizontal flange 32a of the auxiliary member 32. The reinforcement part 38c which protrudes inward of the bearing is formed in the upper part of the part in which the said 1st, 2nd seal lip 38a, 38b joined together.

상기 제1시일립(38a)은 주로 베어링 내부의 그리이스가 외부로 누설되는 것을 방지하고, 상기 제2시일립(38b)는 외부의 이물질이 베어링의 내부로 혼입되는것을 방지한다. 상기 보강부(38c)는 시일재 하부의 강성을 높인다.The first seal lip 38a mainly prevents the grease inside the bearing from leaking to the outside, and the second seal lip 38b prevents foreign matter from entering the inside of the bearing. The reinforcement portion 38c increases the rigidity of the lower portion of the sealing material.

이와 같이 구성된 본 발명에 의한 구름베어링의 시일링장치는 도3에 도시한 바와 같이, 밀봉시일(30)의 머리부를 외륜의 걸림홈띠(24a)에 먼저 끼워 조립한 후, 보조부재(32)의 수평플랜지(32a)의 내면을 내륜(22)의 외면에 밀착되게 억지끼움하여 조립한다. 따라서, 상기 보조부재(32)는 상기 내륜(22)과 함께 회전하게 되어 있다.As shown in FIG. 3, the sealing device for the rolling bearing according to the present invention configured as described above is assembled by first fitting the head of the sealing seal 30 to the locking groove 24a of the outer ring, and then The inner surface of the horizontal flange 32a is assembled by forcing it to be in close contact with the outer surface of the inner ring 22. Accordingly, the auxiliary member 32 is rotated together with the inner ring 22.

이와 같이 조립된 구름베어링의 시일링장치에서, 내륜(22)이 회전하면 보조부재(32)도 동시에 회전하게 되는데, 보조부재(32)의 수직플랜지(32b)와 밀봉시일(30) 사이에 있는 공기 및 이물질은 원심력을 받아 상기 개구부(C) 측으로 빠지게 된다. 특히 보조부재(32)가 회전함에 따라 돌출띠(32c)의 정점(T)과 상측골점(V)사이에는 압력차(정점의 압력이 상측골점의 압력보다 높음)가 생기므로 이물질이 제2시일립(38b)측으로 이동하지 않는다. 따라서, 베어링의 내부로 이물질이 유입할 가능성이 현저히 줄어든다.In the sealing device of the rolling bearing assembled as described above, when the inner ring 22 rotates, the auxiliary member 32 also rotates at the same time, which is located between the vertical flange 32b of the auxiliary member 32 and the sealing seal 30. Air and foreign matter are separated by the centrifugal force toward the opening C side. In particular, as the auxiliary member 32 rotates, a difference in pressure is generated between the vertex T and the upper bone point V of the protruding band 32c, so that the foreign material is sealed in the second seal. It does not move to the lip 38b side. Thus, the possibility of foreign matter entering the inside of the bearing is significantly reduced.

본 발명은 상기 실시예에 한정되지 않으며 다양하게 변형하여 실시할 수 있다.The present invention is not limited to the above embodiments and can be implemented in various modifications.

본 발명에 의한 구름 베어링의 시일링장치에 의하면, 외부로부터 베어링의 내부로 이물질의 혼입방지기능을 더욱 향상하여 베어링의 내구성을 높이는 효과가 있다.According to the sealing device of the rolling bearing according to the present invention, the effect of preventing the incorporation of foreign substances into the bearing from the outside is further improved, thereby increasing the durability of the bearing.
