Description
본 발명은 베어링을 기준으로 하여 베어링의 내륜과 외륜을 작동시키는 회전부재에 있어서 일측의 회전부재에서 발생되는 충격이 타측의 회전부재측으로 전이되는 것을 방지(또는 완화)할 수 있도록 된 충격전이 방지형롤러에 관한 것이다.The present invention provides a shock transfer prevention type for preventing (or mitigating) the impact generated from the rotating member on one side of the rotating member operating the inner and outer rings of the bearing on the basis of the bearing. It is about a roller.
이를 좀 더 상세히 설명하면,In more detail,
롤링베어링(Rolling Bearing)의 내륜과 외륜에 각기 고정되어 개별적으로 작동되도록 된 회전부재에 있어서 베어링이 외륜에 고정되는 회전부재의 구조를 개선하여 외측의 회전부재에서 발생되는 충격이 내측의 회전부재에 전이되지 못하도록 된 것이다.In a rotating member fixed to the inner and outer rings of a rolling bearing, respectively, to be operated separately, the structure of the rotating member in which the bearing is fixed to the outer ring is improved so that the impact generated from the outer rotating member is applied to the inner rotating member. It is not to be transferred.
더욱 상세하게는, 외측의 회전부재를 베어링캡과 동력캡으로 분리하고 이들사이에 완충부재를 개입시켜줌으로서 동력캡에 충격이 가해지더라도 완충부재에 의해 충격이 완화되거나 소멸되어져 베어링캡과 롤링베어링 및 롤링베어링의 내륜에 고정되는 회전부재에 까지 전이되지 못하도록 된 롤러에 관한 것이다.More specifically, by separating the outer rotating member into a bearing cap and a power cap and intervening a shock absorbing member therebetween, even if an impact is applied to the power cap, the shock is alleviated or eliminated by the shock absorbing member so that the bearing cap and the rolling bearing and The present invention relates to a roller that is prevented from being transferred to a rotating member fixed to an inner ring of a rolling bearing.
본 발명에 따른 충격방지형롤러는 롤링베어링을 이용한 것으로서, 롤링베어링의 내륜과 외륜에 고정되는 회전부재를 별도로 작동(회전)시켜 줄 수 있도록 하는 장치와, 이송컨베이어(Conveyor)와 같이 일측의 회전부재만을 작동(회전)시켜줄 수 있도록 하는 장치에 장착하여 사용할 수 있는 것이다.An impact resistant roller according to the present invention uses a rolling bearing, and an apparatus for allowing the rotating members fixed to the inner and outer rings of the rolling bearing to operate (rotate) separately, and to rotate on one side such as a conveying conveyor. It can be used by attaching to a device that can only operate (rotate) the member.
도 5는 종래의 롤러장치를 이송컨베이어의 롤러(70)에 장착시킨 상태를 보인 예시도로서,5 is an exemplary view showing a state in which a conventional roller device is mounted on a roller 70 of a conveying conveyor.
롤러베어링(72)의 내륜(72-1)를 삽입하여 고정시키고,Insert and fix the inner ring 72-1 of the roller bearing 72,
외륜(72-2)에는 베어링캡(73)을 삽입 고정시키되 원통부(73-1)를 외륜(72-2)에 삽입 고정시키고 플랜지부(73-2)에 롤러(70)를 고정시키며, 롤링베어링(72)과 샤프트(71)의 틈새를 통하여 외부의 먼지나 이물질이 롤러(70)의 내부로 유입되지 않도록 롤링베어링(72)의 외측으로 노출되는 샤프트(71)에 밀폐링(74)을 끼우고 원통부(73-1)의 내주면에 형성된 환상고정홈 (73-3)에 고정캡(75)을 장착하여 밀폐링(74)이 이탈되지 못하도록 환상고정홈(73-3)에 고정캡(75)을 장착하여 밀폐링(74)이 이탈되지 못하도록 하여서 된 것이다.The bearing cap 73 is inserted and fixed to the outer ring 72-2, and the cylindrical portion 73-1 is inserted and fixed to the outer ring 72-2, and the roller 70 is fixed to the flange portion 73-2. The sealing ring 74 on the shaft 71 which is exposed to the outside of the rolling bearing 72 so that external dust or foreign matter does not flow into the roller 70 through the gap between the rolling bearing 72 and the shaft 71. The fixing cap 75 to the annular fixing groove 73-3 formed on the inner circumferential surface of the cylindrical portion 73-1 to secure the annular fixing groove 73-3 to prevent the sealing ring 74 from being separated. The cap 75 is attached to prevent the sealing ring 74 from being separated.
이와 같이 된 종래의 컨베이어용롤러는 샤프트(71)를 별도의 지지대(구체적으로 도시하지 아니함)에 회전되지 못하도록 고정시켜 주고, 롤러(70)와 베어링캡(73) 및 외륜(72-2)이 롤링베어링(72)의 볼(72-3)에 의해 내륜(72-1) 및 샤프트(71)와는 무관하게 회전하게 되며, 회전되는 롤러(70)의 위로 이송물을 슬라이딩시키게 되면 롤러(70)가 회전되면서 이동하게된다.Conventional conveyor rollers as described above are fixed to the shaft 71 so as not to rotate on a separate support (not shown specifically), the roller 70, the bearing cap 73 and the outer ring (72-2) The ball 72-3 of the rolling bearing 72 rotates irrespective of the inner ring 72-1 and the shaft 71, and when the feed is slid over the rotated roller 70, the roller 70. It will move as it is rotated.
이와 같이 구성되고 작동되는 종래의 장치는 다음과 같은 문제가 단점으로 지적된다. 샤프트(71)가 수평상태를 유지하지 못하게 되면 좌우편심으로 인하여 베어링의 마모가 심하고 부하가 많이 갈리게 되며 그로 인하여 소음이 발생되거나 수명이 단축되는 문제가 있었다.The conventional device constructed and operated as described above has the following disadvantages. When the shaft 71 is not maintained in a horizontal state, the wear of the bearing is severe and the load is largely diverged due to the left and right eccentricity, thereby causing noise or shortening the lifespan.
또한 물품을 이송시키거나 할때 충격이 롤러(70)에 가해지게 되면, 롤러(70)에는 베어링캡(73)이 직접 연결되어 있으므로 롤러(70)에 가해진 충격은베어링캡(73)을 직접 전이되어지고, 베어링캡(73)에는 롤링베어링(72)이 직접 장착되어 있으므로 베어링캡(73)으로 전이된 충격은 롤링베어링(72)에 가해지게 된다.In addition, when an impact is applied to the roller 70 when the goods are transported or the like, the bearing cap 73 is directly connected to the roller 70, so that the impact applied to the roller 70 directly transfers the bearing cap 73. Since the rolling bearing 72 is directly mounted to the bearing cap 73, the shock transferred to the bearing cap 73 is applied to the rolling bearing 72.
롤링베어링(72)에 충격이 가해지면 외륜(72-2)와 내륜(72-1)이 변형되는 현상이 발생될 뿐만아니라 볼(72-3)이 깨지는 현상이 발생하여 롤링베어링(72)이 원할하게 작동되지 못하게 되고 그로 인하여 이송컨베이어의 성능을 약화시키는 문제가 있었다.When the impact is applied to the rolling bearing 72, not only the outer ring 72-2 and the inner ring 72-1 are deformed, but also the ball 72-3 is broken, so that the rolling bearing 72 is broken. There was a problem that can not work smoothly and thereby weaken the performance of the transfer conveyor.
또, 롤링베어링(72)으로 가해지는 충격이 샤프트(71)에도 직접 가해지게 되므로 롤러(70)의 양측에 구비되는 롤링베어링(72)의 충격차이로 인하여 샤프트(71)가 변형되거나 뒤틀리게 되면서 수평상태를 유지시켜주지 못하게 되고, 샤프트(71)가 변형되면 롤링베어링(72)도 원활하게 작동되지 못하게 되며, 그로 인하여 롤러(70)도 변형되어 외주면이 롤링하듯이 불균형적으로 회전하게 되므로 물품을 원활하게 이송시킬 수 없는 문제가 있었다.In addition, since the impact applied to the rolling bearing 72 is directly applied to the shaft 71, the shaft 71 is deformed or distorted due to the impact difference between the rolling bearings 72 provided on both sides of the roller 70, thereby being horizontal. If the shaft 71 is deformed, the rolling bearing 72 may not operate smoothly. As a result, the roller 70 may be deformed to rotate unbalanced as the outer circumferential surface is rolled. There was a problem that cannot be transferred smoothly.
특히, 충격이 심하거나 누적되어지면 샤프트(71)를 지지하고 있는 컨베이어의 지지대조차도 뒤틀리거나 하는 변형이 발생하여 샤프트(71)와 그 양측에 고정되는 롤링베어링(72)이 수평상태를 이루지 못하고 편차가 발생되어 베어링의 마모가 심하고 부하가 많이 걸려 롤러(70)가 회전된 못하게 되며 수명이 단축되고 소음이 발생되는 문제도 있었다.In particular, when the impact is severe or cumulative, even a support of the conveyor supporting the shaft 71 is deformed or deformed so that the shaft 71 and the rolling bearing 72 fixed to both sides do not form a horizontal state and are deformed. There was a problem that the wear of the bearing is severe and the load is too much to prevent the roller 70 is rotated and the life is shortened and noise is generated.
또한 구체적으로 도시하지는 아니하였으나 롤링베어링(72)의 내륜(72-1)에 샤프트(71)와 같은 제1회전부재를 고정시키고 외륜(72-2)에 고정된 베어링캡(73)에 제2회전부재를 고정시켜 제1·제2회전부재를 각기 별도로 회전시킬 수 있도록 된 것일 경우에 있어서, 제1회전부재 또는 제2회전부재에서 충격이 발생할 경우에는 그 충격이 즉시 타측의 회전부재로 전이되면서 타측회전부재의 회전을 방해하여 회전력을 떨어뜨리게 되고 회전부재의 연결수단(장치)이 변형되어 회전력을 떨어뜨릴뿐만아니라 파손시키기 까지 하는 문제가 있었다.이러한 문제를 해소할 수 있도록 제안된 것으로는 일본국 공개실용신안 공개번호 소54-21391호 '컨베이어롤러의 밀봉'장치가 알려져 있다.이는 축에 삽입 고정된 베어링의 외륜과 롤러와의 사이에 탄성부재를 끼워 고정시키되 탄성부재의 양측에 원판상의 판부재를 각각 구비하여 통상의 볼트, 너트에 의해 탄성부재와 함께 일체형으로 고정시키고, 베어링(2)의 외측으로 노출되는 축에 실부재를 밀폐되게 삽입 창작시키되 실부재와 판부재와의 사이에 형성된 공간에 구리스를 충진시켜서 된 것으로서, 축과 베어링의 내륜 및 실부재가 고정된 상태에서 롤러와 함께 일체형으로 된 탄성부재와 판부재 및 베어링의 외륜이 함께 회전하도록 하고 탄성부재가 롤러의 충격을 완화시켜 축에 전이되지 못하도록 된 것이다.그러나, 이는 롤러와 베어링의 사이에 끼워지는 탄성부재를 팽창시켜 견고하게 결합시킬 수 있도록 탄성부재의 양측에 판부재를 각각 구비하고 볼트, 너트로 결합시켜주어야만 하므로 설치가 용이치 못하고 작업능률이 현저히 떨어지고, 실부재와 판부재와의 사이에 구리스를 충진시켜 외부의 이물질이 유입되는 것을 방지하도록 하고 있으나 충진된 구리스가 롤러의 근접부근에서 외부로 누출되면서 외부로 비산되어 이송되는 제품에 묻어지거나 주변을 오염시키는 문제가 있었다.In addition, although not specifically illustrated, the first rotating member such as the shaft 71 is fixed to the inner ring 72-1 of the rolling bearing 72 and the second bearing 2 is fixed to the bearing cap 73 fixed to the outer ring 72-2. When the rotating member is fixed so that the first and second rotating members can be rotated separately, when an impact occurs in the first rotating member or the second rotating member, the impact immediately transfers to the other rotating member. As a result, the rotational force of the other rotating member is disturbed to reduce the rotational force, and the connecting means (device) of the rotating member are deformed to reduce the rotational force and to destroy it. Japanese Utility Model Publication No. 54-21391, 'Conveyor Roller Sealing', is known, which is used to secure an elastic member between the roller and the outer ring of a bearing inserted into a shaft. Plate members on both sides of the elastic member are provided with plate members, respectively, and fixed together with the elastic member by means of ordinary bolts and nuts, and the seal member is inserted into the shaft exposed to the outside of the bearing 2 to be creatively created. The grease is filled in the space formed between the plate member and the plate member, and the elastic member, the plate member and the outer ring of the plate member and the bearing rotate together with the roller while the inner ring and seal member of the shaft and the bearing are fixed. The elastic member is to prevent the impact of the roller to be transferred to the shaft. However, it is provided with a plate member on each side of the elastic member so as to expand and firmly bond the elastic member sandwiched between the roller and the bearing, Since it must be combined with bolts and nuts, installation is not easy and work efficiency is significantly reduced. This is to prevent grease from entering the outside by filling the grease, but the filled grease was leaked to the outside in the vicinity of the roller was scattered to the outside to be buried in the product to be transported or contaminated the surroundings.

도 4는 본 발명에 따른 충격전이 방지형롤러장치(1)의 구체적인 사용상태의 실시예를 보인 예시도로서 컨베이어용롤러(80)의 양측에 장착시킨 상태의 예시도이다.Figure 4 is an exemplary view showing an embodiment of a specific use state of the impact-transmission prevention roller device 1 according to the present invention is an illustration of a state mounted on both sides of the conveyor roller (80).
충격전이 방지형롤러장치(1)를 롤러(80)와 샤프트(81)에 장착시키되 샤프트(81)에 스톱퍼링(2-1)을 구비하여 롤링베어링(4)이 내측으로 이동되지 못하도록 하였고 동력캡(30)의 외측원통부(33)를 롤러(80)의 양단에 각각 삽입하여 용접과 같은 수단에 의해 고정시켜 주도록 하였으며,The impact transfer prevention roller device 1 is mounted on the roller 80 and the shaft 81, but the stop bearing ring 2-1 is provided on the shaft 81 to prevent the rolling bearing 4 from moving inward. The outer cylindrical portion 33 of the cap 30 is inserted into both ends of the roller 80 to be fixed by means such as welding,
샤프트(81)의 양단은 구체적으로 도시하지는 아니하였으나 지지대에 삽입하여 회전되지 않도록 억류하였다. 이와 같이 지지대에 롤러(80)를 굴대설치하여 통상컨베이어를 완성하고 사용하게 된다.Although not specifically illustrated, both ends of the shaft 81 are inserted into the support and detained so as not to rotate. In this way, the roller 80 is installed on the support bar to complete the normal conveyor.
롤러(80)의 위에 이송물품(구체적으로 도시하지 아니함)을 올려놓고 임의수단에 의해 이송물품을 밀어주게 되면 이송물품이 롤러(80)에서 슬라이딩될때 롤러(80)는 제2회전부재(3)와 함께 회전하게 되며, 따라서 이송물품은 용이하게 슬라이딩 이동하게 된다.When the conveying article (not specifically shown) is placed on the roller 80 and the conveying article is pushed by any means, the roller 80 is rotated by the second rotating member 3 when the conveying article is slid from the roller 80. And rotates together, so the conveyed article is easily slid.
이와 같이 하면서 컨베이어를 사용하는 도중에 이송물품을 올려놓을때 발생되는 충격이나 또는 다른 여타의 충격이 롤러(80)에 가해지게 되면 그 충격은 제2회전부재(3)측으로 전이 되어지는데, 롤러(80)와 연결되어 있는 제2회전부재(3)의 동력캡(30)에 충격이 전이 되어지고 동력캡(30)은 그 내측으로 완충부재(20)에 의해 베어링캡(10)과 분리되어 있으므로 동력캡(30)에 전이된 충격은 완충부재(20)에 흡수되어 소멸되어지게 되며, 베어링캡(10)에는 충격이 거의 전이되지 않거나 미미한 정도만이 전이 되어질뿐이며, 따라서 롤링베어링(4)과 샤프트(81)에는 충격이 전이되지 않거나 매우 미미한 정도만이 이전 이되어질 뿐이다.In this way, if an impact or other impact generated when the conveying article is placed while using the conveyor is applied to the roller 80, the impact is transferred to the second rotating member 3 side, and the roller 80 Shock is transferred to the power cap 30 of the second rotating member 3 which is connected to the) and the power cap 30 is separated from the bearing cap 10 by the shock absorbing member 20 therein. The shock transferred to the cap 30 is absorbed by the shock absorbing member 20 to be extinguished, and the bearing cap 10 has only little or no shock transmitted. Therefore, the rolling bearing 4 and the shaft ( 81) the shock is not transmitted or only a very small amount is transferred.
결국, 롤러(80)에 충격이 가해지더라도 그 충격은 환중부재(20)에 흡수되어 롤링베어링(4)과 샤프트(81)에는 전이되지 않게 되고, 따라서 롤링베어링(4)과 샤프트(81)가 손상되거나 깨지거나 변형되는 것을 방지할 수 있는 것이다.As a result, even if an impact is applied to the roller 80, the impact is absorbed by the ring member 20 and is not transferred to the rolling bearing 4 and the shaft 81, so that the rolling bearing 4 and the shaft 81 are It can be prevented from being damaged, broken or deformed.
이상에서와 같이 본 발명에 따르면,As described above, according to the present invention,
롤링베어링의 외륜에 장작되는 제2회전부재를 베어링캡과 동력캡의 사이에 완충부재를 구비함으로서 동력캡에 가해지는 충격을 완충부재가 흡수하여 소멸시켜 롤링베어링과 그의 내륜에 고정되는 샤프트와 같은 제1회전부재에 충격이 가해지는 것을 방지하므로 외부의 충격에 의해 롤링베어링이 깨지거나 제1회전부재가 변형 및 뒤틀리는 현상을 방지할 수 있다는 것이다.The second rotating member mounted on the outer ring of the rolling bearing includes a cushioning member between the bearing cap and the power cap, so that the shock absorbing member absorbs and extinguishes the shock applied to the power cap, such as a shaft fixed to the rolling bearing and its inner ring. Since the impact is prevented from being applied to the first rotating member, the rolling bearing is broken or the first rotating member is deformed and distorted by an external impact.
