Description

운동기구용 수밀 베어링{sealing bearing}Watertight bearings for sports equipment

본 발명은 베어링에 관한 것으로, 더욱 상세하게는 야외의 회전식 운동기구에 사용되는 운동기구용 수밀 베어링에 관한 것이다.The present invention relates to a bearing, and more particularly to a watertight bearing for a sports equipment used for outdoor rotary sports equipment.

베어링은 회전이나 왕복 운동하는 상대 부품에 접해 하중을 받아 축 등을 지지하는 부품이다. 즉, 축을 정확하고 매끄럽게 회전시키기 위해서 사용되고, 마찰에 의한 에너지 손실이나 발열을 감소시켜, 부품의 손상을 막으며, 수송 기계를 시작해 각종 기계에 널리 사용되지만, 거기에 한정하지 않더라도 회전하는 부분이 있는 기기에는 반드시 존재한다.A bearing is a part which supports a shaft etc. under a load in contact with a counterpart part which rotates or reciprocates. That is, it is used to rotate the shaft accurately and smoothly, and it reduces the energy loss and heat generation by friction, prevents the damage of the parts, and is widely used in various machines including the transportation machine, but there is a part to rotate even if not limited thereto. It must exist on the device.

상기한 베어링의 유용성 때문에 야외 공원이나 체육관 등의 회전식 운동기구에 베어링이 많이 사용되는데, 베어링의 단점 중 하나는 베어링에 삽입된 쇠구슬이 회전할 때 마찰에 의해 발생되는 소음이다.Due to the usefulness of the bearings, the bearings are frequently used in rotary sports equipment such as an outdoor park or a gymnasium. One of the disadvantages of the bearings is noise generated by friction when the metal ball inserted in the bearing rotates.

베어링에서 발생되는 소음은 베어링을 이루는 쇠구슬과 쇠구슬이 고정되는 하우징 및 회전체와의 마찰력에 의해서 발생된다. 따라서 마찰력을 줄이기 위해 베 어링에는 윤할제인 그리스 등을 채워넣어 마찰력을 감소시킴으로써 베어링의 수명을 연장시키고 소음을 감소시킨다.Noise generated in the bearing is generated by the frictional force between the steel ball forming the bearing and the housing and the rotating body to which the steel ball is fixed. Therefore, in order to reduce friction, bearings are filled with grease, which is a lubricant, to reduce friction, thereby extending bearing life and reducing noise.

기계나 기구 등에 사용되는 베어링은 일반적으로 폐쇄된 특정 공간에 설치되기 때문에 베어링의 내부로 물이 들어가는 경우가 거의 없지만, 야외의 공원 등에 설치되는 운동기구는 구조가 간단하고, 단순하여 베어링을 빗물이나 수분 등으로 부터 보호하는 구조가 형성되어 있지 않고 노출되어 있는 것이 일반적이다.Since the bearings used in machinery and equipment are generally installed in a closed specific space, water rarely enters the inside of the bearings. However, the sports equipment installed in an outdoor park has a simple structure and is simple. It is common that the structure which protects from moisture etc. is not formed but it is exposed.

본 발명은 전술한 바와 같은 문제점을 해결하기 위한 것으로, 베어링이 설치되는 베어링 장착구멍으로 빗물이나 수분이 스며들 수 없는 구조를 형성하여 베어링에 발라진 윤활제가 빗물이나 수분과 접촉되지 않도록 하여 윤활 상태를 장기간 유지되도록 함으로써 운동기구를 유지보수를 용이하게 하고자 한다.The present invention is to solve the above problems, to form a structure that can not see the rain or moisture into the bearing mounting hole in which the bearing is installed so that the lubricant applied to the bearing is not in contact with rain or moisture to improve the lubrication state It is intended to facilitate maintenance of the exercise equipment by maintaining it for a long time.

본 발명은 상기의 목적을 달성하기 위하여 고정기둥의 외측에 돌출되어 형성되는 플랜지 형태의 암과, 상기 암의 중공부 선단 외주를 따라 형성되는 링홈과, 상기 암에 밀착 결합되고 중앙에는 베어링 장착구멍이 형성된 베어링판과, 상기 베어링판의 내측으로 돌출된 링고정구와, 상기 링고정구의 외주에 삽입되는 패킹링과, 상기 베어링판의 외측으로 연장되어 형성되는 베어링 하우징과, 상기 베어링 하우징에 압입되고 단부에는 링턱이 형성된 리데나와, 상기 리데나의 링턱에 삽입되는 패킹재와, 상기 베어링판의 장착구멍에 삽입 체결되는 베어링과, 상기 베어링의 내륜에 삽입 체결되는 회전축과, 상기 회전축의 일단에 형성되는 단부에 일체로 형성되면서 베어링 하우징을 감싸도록 전면이 원통형으로 돌출된 축부재;를 포함하여 이루어진 것을 특징으로 하는 운동용 기구의 수밀 베어링를 제공한다.The present invention is a flange-shaped arm is formed to protrude to the outside of the fixing pillar to achieve the above object, a ring groove formed along the outer periphery of the hollow portion of the arm, and closely coupled to the arm and the bearing mounting hole in the center The formed bearing plate, a ring fixture projecting into the bearing plate, a packing ring inserted into an outer circumference of the ring plate, a bearing housing extending outwardly of the bearing plate, and pressed into the bearing housing, At the end, a lidena has a ring jaw, a packing material inserted into the ring jaw of the lidena, a bearing inserted into the mounting hole of the bearing plate, a rotating shaft inserted into the inner ring of the bearing, and one end of the rotating shaft. And a shaft member protruding in a cylindrical shape so as to be integrally formed at the end portion formed so as to surround the bearing housing. A watertight bearing of an exercise device is provided.

본 발명에 따른 운동기구용 수밀 베어링은 베어링 장착구멍으로 빗물이나 수분이 스며들지 못하기 때문에 베어링에 발라진 윤활제가 수분에 의해 부폐하거나 씻겨 내려가지 않으므로 윤활상태를 장기간 유지할 수 있고, 이로 인해 윤활 문제로 빈번히 발생되던 운동기구의 소음 문제가 발생되지 않으므로 운동기구를 사용자로부터 불만사항을 크게 감소시킬 수 있고, 기능적으로도 베어링의 사용기간을 늘릴 수 있다.Watertight bearings for sports equipment according to the present invention can maintain the lubrication state for a long time because the lubricant applied to the bearing is not broken or washed away by the moisture because the rainwater or moisture does not penetrate into the bearing mounting hole, Since the noise problem of the exercise equipment which is frequently generated does not occur, the exercise equipment can greatly reduce the complaints from the user, and can also functionally increase the service life of the bearing.

이하, 첨부된 도면을 참조하여 본 발명을 상세히 설명하면 다음과 같다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

상기 암(110)에는 중공된 원판형의 베어링판(200)이 결합된다. 베어링판(200)의 중앙에는 베어링이 삽입 결합될 수 있도록 베어링 장착구멍(210)이 형성 되어 있고, 베어링 장착구멍(210)의 전방으로는 돌출된 원통형의 링고정구(220)가 형성되고, 링고정구의 외주에는 패킹링(230)이 끼워진다.The arm 110 is coupled to the bearing plate 200 of the hollow disc shape. A bearing mounting hole 210 is formed in the center of the bearing plate 200 so that the bearing can be inserted and coupled, and a cylindrical ring fixture 220 protruding in front of the bearing mounting hole 210 is formed, and Ringo Packing ring 230 is fitted to the outer circumference of the tennis ball.

베어링 장착구멍(210)의 후방으로는 돌출된 베어링 하우징(240)이 형성된다. 베어링 하우징(240)의 선단 내주에는 연질금속으로 이루어진 중공된 리데나(250)가 압입된다. 리데나(250)의 선단에는 패킹홈(260)이 형성되고, 패킹홈에는 패킹재(270)가 삽입된다. 상기 리데나(260)의 내경은 후술하는 회전축의 외경을 고려하여 설계한 것으로 회전축이 결합될 때 회전축의 끝 부분에 가압되어 압력이 가해지도록 한 것이다. 상기 리데나는 아연 30 ~ 90 중량%이고 나머지는 주석이나 구리 및 다른 금속을 혼합한 합금으로 하는 것이 연성이나 경도면에서 유리하다. Protruding bearing housing 240 is formed behind the bearing mounting hole 210. A hollow lidena 250 made of a soft metal is press-fitted into the tip inner circumference of the bearing housing 240. A packing groove 260 is formed at the tip of the lidena 250, and a packing material 270 is inserted into the packing groove. The inner diameter of the lidena 260 is designed in consideration of the outer diameter of the rotating shaft to be described later is to be pressed to the end of the rotating shaft when the rotating shaft is coupled to apply pressure. The lidena is 30 to 90% by weight of zinc and the remainder is advantageous in terms of ductility and hardness of the alloy mixed with tin, copper and other metals.

베어링 장착구멍(210)에는 볼베어링(280)이 삽입 설치되고, 볼베어링(280)의 내륜에는 축하우징(240)을 통해 회전축(300)이 삽입 설치되며, 회전축(300) 상단에는 와셔(292)를 끼운 후 볼트(294) 체결하여 회전축(300)을 고정시킨다.A ball bearing 280 is inserted into and installed in the bearing mounting hole 210, and a rotating shaft 300 is inserted into an inner ring of the ball bearing 280 through a celebratory housing 240, and a washer 292 is disposed at the top of the rotating shaft 300. After fitting the bolt (294) by fastening the rotating shaft (300).

회전축(300)의 일단에는 회전축(300)과 일체로 전방이 개방된 원통형의 축부재(310)가 형성된다. 여기서 축부재(310)의 개방된 길이는 베어링 하우징(240)의 길이를 고려하여 설계함으로써 베어링판(200)에 결합될 때 베어링 하우징(240)을 완전히 감쌀 수 있도록 한다.One end of the rotating shaft 300 is formed with a cylindrical shaft member 310, the front of which is integrally open with the rotating shaft 300. Here, the open length of the shaft member 310 is designed in consideration of the length of the bearing housing 240 so as to completely wrap the bearing housing 240 when coupled to the bearing plate 200.

상기와 같이 구성된 운동기구용 수밀 베어링의 조립 및 작동상태를 설명하면 다음과 같다.Referring to the assembly and operating state of the water-tight bearing for sports equipment configured as described above are as follows.

베어링판(200)의 베어링 장착구멍(210)에 베어링(280)을 삽입 설치하고, 베어링 하우징(240)에 리데나(250)를 압입한 상태에서, 회전축(300)을 베어링(280)의 내륜에 삽입한다. 베어링(280)은 회전시 상호간의 마찰로 인한 마모나 소음을 감소시키기 위해 그리스와 같은 윤할유를 먼저 발라 놓는다.In the state where the bearing 280 is inserted into the bearing mounting hole 210 of the bearing plate 200 and the lidena 250 is pressed into the bearing housing 240, the rotating shaft 300 is inserted into the inner ring of the bearing 280. Insert in The bearing 280 is first coated with a lubricant such as grease to reduce abrasion or noise due to mutual friction during rotation.

회전축(300)이 베어링(280)의 내륜에 삽입한 후 베어링(280)의 외측으로 돌출된 회전축(300)의 상단에 와셔를 끼우고 여기에 볼트를 체결하여 회전축(300)을 베어링판200)에 단단히 고정시킨다.After the rotating shaft 300 is inserted into the inner ring of the bearing 280, a washer is inserted into the upper end of the rotating shaft 300 protruding outward of the bearing 280 and the bolt is fastened to the rotating shaft 300 to the bearing plate 200. Securely in place.

회전축(300)이 베어링판(200)에 고정될 때 회전축(300)의 끝 부분이 리데나(250)의 내주에 밀착되는데, 리데나(250)의 패킹홈(260)에는 패킹재(270)가 삽입되어 있기 때문에 회전축(300)의 끝 부분에 의해 압력이 가해져 수밀이 유지된다.When the rotating shaft 300 is fixed to the bearing plate 200, the end of the rotating shaft 300 is in close contact with the inner circumference of the lidena 250, the packing member 270 in the packing groove 260 of the lidena 250 Since is inserted, the pressure is applied by the end of the rotary shaft 300 to maintain the watertight.

이때 패킹재(270)는 연한금속 재질의 리데나(260)에 안착되어 있으므로 볼트의 조임에 따라 강하게 밀착된다.At this time, since the packing material 270 is seated on the soft metal lidena 260, the packing material 270 is tightly adhered by tightening the bolt.

그리고 회전축(300)에 일체로 결합된 원통형의 축부재(310) 선단은 회전축(300)이 베어링판(200)에 결합될 때 베어링 하우징(240)을 완전히 감싼다.And the tip of the cylindrical shaft member 310 integrally coupled to the rotary shaft 300 completely surrounds the bearing housing 240 when the rotary shaft 300 is coupled to the bearing plate 200.

회전축(300)이 베어링판(200)에 결합된 상태에서 링고정구(220)에 패킹링(230)을 삽입하고, 베어링판(200)을 고정기둥(100)의 암(110)에 볼트/너트로 결합시킨다.The packing ring 230 is inserted into the ring fixture 220 in the state in which the rotating shaft 300 is coupled to the bearing plate 200, and the bearing plate 200 is bolted to the arm 110 of the fixing column 100. Combine with

베어링판(200)을 암(110)에 밀착시키면 링고정구(220)가 암(110)의 중공부에 삽입되면서 링고정구(220)의 외주에 삽입된 패킹링(230)이 링홈(120)에 밀착된다. 베어링판(200)이 암(110)에 밀착된 상태에서 베어링판(200)에 형성된 볼트구멍에 볼트/너트를 끼우고 암(110)과 단단히 결합시키면 패킹링(230)이 더욱 밀착되면서 베어링판(200)과 베어링 장착구멍(210) 사이에 수밀이 유지된다.When the bearing plate 200 is in close contact with the arm 110, the ring fitting 220 is inserted into the hollow of the arm 110, and the packing ring 230 inserted into the outer circumference of the ring fitting 220 is inserted into the ring groove 120. Close contact. In the state in which the bearing plate 200 is in close contact with the arm 110, the bolt / nut is inserted into the bolt hole formed in the bearing plate 200 and tightly coupled with the arm 110. Watertightness is maintained between the 200 and the bearing mounting hole 210.

상기와 같이 회전축(300)이 결합된 베어링판(200)을 고정기둥(100)의 암(110)에 결합한 상태에서 도 4와 도 5에 도시된 바와 같은 운동기구(400)를 원통형의 축부재(310)에 결합하면 운동기구의 설치가 완성된다. 즉 운동기구(400)의 하단에 형성된 발판에 발을 올려놓고 고정기둥(100) 상단에 설치된 철봉(T)을 잡은 상태에서 전후로 밀거나 당기면서 운동을 하는 것이다.As described above, in the state in which the bearing plate 200 coupled with the rotating shaft 300 is coupled to the arm 110 of the fixed pillar 100, the exercise device 400 as illustrated in FIGS. 4 and 5 has a cylindrical shaft member. When combined with the 310, the installation of the exercise equipment is completed. That is to put the foot on the footrest formed on the lower end of the exercise device 400 and to exercise while pushing or pulling back and forth while holding the iron bar (T) installed on the top of the fixing column (100).

운동기구는 공원과 같은 야외에 설치되는 경우가 많는데, 비가오면 구성부간의 연결부를 통해 빗물이 스며든다.Exercise equipment is often installed outdoors, such as parks, when rain rains seep through the connections between the components.

원통형의 축부재(320)로 베어링 하우징을 완전히 감쌌다 해도 그 사이로 빗물이 스며드는데, 빗물은 축부재(320)의 내부를 타고 흘러들어 회전축(300)과 축부재(310)의 연결부에 다다른다. 이 곳에 다다른 빗물은 회전축(300)을 타고 역류하여 리데나(250)와 회전축(300) 사이로 스며들 수도 있지만 연질금속인 리데나(250)의 자체 탄성력과 리데나(250)의 패킹홈(260)에 형성된 패킹재(270)가 회전축의 끝 부분데 눌려 있으므로 빗물은 스며들지 못하고 여분의 축부재(310) 공간을 타고 자연스럽게 빠져나간다.Even though the bearing housing is completely enclosed by the cylindrical shaft member 320, rain water penetrates therebetween, and the rainwater flows through the inside of the shaft member 320 to reach the connection portion between the rotary shaft 300 and the shaft member 310. Rainwater that has reached here may flow back through the rotating shaft 300 to penetrate between the lidena 250 and the rotating shaft 300, but the self-elastic force of the soft metal lidena 250 and the packing groove of the lidena 250 ( Since the packing material 270 formed in the 260 is pressed at the end of the rotating shaft, rainwater does not penetrate and naturally escapes through the extra shaft member 310 space.

암(110)과 베어링판(200) 사이를 통해 빗물이 스며들 수 있지만, 이때는 베어링판(200)과 암(110) 사이에 밀착된 패킹링(230)에 의해 빗물의 유입이 차단된다.Rainwater may penetrate between the arm 110 and the bearing plate 200, but at this time, the inflow of the rainwater is blocked by the packing ring 230 closely contacted between the bearing plate 200 and the arm 110.

상기한 바와 같이 빗물(수분)은 베어링 장착구멍(210)으로 스며들 수 없으므로 베어링은 빗물과 접촉될 수 없다. 즉 베어링에 발라진 윤할유는 빗물의 의해 부페되지 않고 또한 빗물과 함께 씻겨 나가지 않으므로 장기간 사용해도 윤할이 유지 되어 마찰로 인한 소음이 발생 되지 않는다.As described above, since rainwater (moisture) cannot penetrate into the bearing mounting hole 210, the bearing cannot contact the rainwater. In other words, the lubricating oil applied to the bearings is not buried by rainwater and is not washed out with the rainwater, so the lubrication is maintained even after long-term use and no noise is generated due to friction.
