Description

필로형 블럭 베어링{PILLOW BLOCK BEARING}Pillow Block Bearings {PILLOW BLOCK BEARING}

본 발명은 대형 철판과 같은 중량물 이송용 롤러의 롤러축 회전용 필로형 블럭 베어링에 관한 것으로서, 특히 본 발명인의 선출원 특허인 엔지니어링 플라스틱이나 슈퍼엔지니어링 플라스틱 재질로 된 필로형 블럭 베어링에서 베어링 역할을 하는 축받이공에 오일 공급용 환상요구, 오일 공급용 니플 및 오일주입공이 관통된 필로형 블럭 베어링 내에 별도의 부시와, 볼이 내장된 볼베어링과 베어링 케이스로된 베어링 유니트를 베어링 디스크와 접하여 유연하게 회전되도록 장착한 필로형 블럭 베어링에 관한 것이다.The present invention relates to a pillow-type block bearing for rotating a roller shaft of a heavy-duty roller such as a large steel plate, and in particular, a bearing supporting a bearing in a pillow-type block bearing made of engineering plastic or super-engineering plastic, which is the patent application of the present inventor. In the pillow-type block bearing penetrated by the annular demand for oil supply, the nipple for oil supply, and the oil injection hole, a bearing unit consisting of a separate bush, a ball bearing with a ball and a bearing case is mounted so as to rotate flexibly in contact with the bearing disc. It relates to a pillow block bearing.

철판 운반용 롤러를 장착하는 필로형 블럭 베어링(Pillow block bearing)은 일반적으로 블럭내에 볼 베어링만 장착한 베어링이거나 본 출원인의 선 특허 제127248호의 경우와 같이 엔지니어링 플라스틱이나 슈퍼엔지니어링 플라스틱으로된 강도가 우수하고 윤활성이 좋은 플라스틱 판재를 소재로 하여 제작된 베어링 본체의 축받이공에 오일을 주입하도록된 필로형 블럭베어링이 있으나, 전자의 경우 롤러축과 볼 및 블럭 등이 모두 스테인레스 등과 같은 금속인 관계로 회전을 거듭함에 따라 마모가 심하여 축받이 내경과 롤러 축 및 볼이 쉽게 마모되어 느슨해 지게 되는 결점이 있고 따라서 축받이 즉 블럭 베어링을 자주 갈아야 하므로 비용손실이 많고 작업능률이 떨어지게 되는 폐단이 있는가 하면 두꺼운 철판을 운반하기 위해서 롤러 위로 철판을 얹어 놓는 과정에서 철판에 의하여 롤러와 블럭 베어링에 심한 충격을 가하게 되면 금속으로된 블럭 베어링은 균열이 생기거나 파괴되거나 또는 변형되기도하여 사용이 불가능 하게 되므로 새로운 블럭 베어링을 자주 교체하여야 하는 번거로움과 불편함이 있었다.Pillow block bearings equipped with steel plate transporting rollers are generally bearings with only ball bearings in the block, or have high strength made of engineering plastics or super-engineering plastics as in the case of the applicant's prior patent No. 127248. There is a pillow-type block bearing in which oil is injected into the bearing hole of a bearing body made of a plastic material with good lubrication. However, in the former case, the roller shaft, the ball, and the block are all made of metal such as stainless steel, so that rotation is performed. As a result, the wear and tear of bearings, roller shafts and balls are easily worn and loosened. Therefore, bearings or block bearings have to be changed frequently, resulting in costly loss and reduced working efficiency. In order to put the iron plate on the roller If the roller and the block bearing are severely impacted by the steel plate during the process, the metal block bearing may be cracked, destroyed, or deformed, making it impossible to use, so it is inconvenient and inconvenient to replace the new block bearing frequently. There was this.

후자의 경우에는 재질이 강도가 높은 플라스틱이고 축받이공이 평활하여 윤활성이 우수하고 게다가 거기에 오일을 공급하게 되면 축의 회전력이 더욱 좋고 녹이 쓸지 않는등 좋은 장점은 있기는 하지만 이역시 강력한 충격과 압력에는 내구성이 약할 뿐 아니라 축받이공 자체가 베어링역할을 하게 되므로 무거운 하중에 눌리게되면 베어링 작용 즉 윤활성이 약해지는 결점이 있었다.In the latter case, the material is made of high-strength plastic and the bearing hole is smooth, so it has excellent lubricity. In addition, if the oil is supplied to it, the rotational force of the shaft is better and it does not rust. Not only this weakness, but the bearing hole itself acts as a bearing, so when pressed under heavy load, the bearing function, that is, lubricity was weakened.

본원 발명은 상기와 같은 종래의 볼 베어링으로 구성된 금속재질의 필로형 블럭 베어링이나, 플라스틱으로되고 오일이 공급되는 필로형 블럭 베어링의 결점을 개선하기 위하여 본 발명인의 선특허에서 개시된 바와같이 플라스틱 재질로되고 오일공급용 니플에의해 오일을 공급하는 기존의 필로형 블럭베어링내에 별개의 베어링 디스크를 장착한 다음 그 베어링 디스크를 매개로 하여 또 다른 볼베어링유닛트을 장착하므로써 축받이가 베어링 효과를 최대한으로 발휘하도록한 필로형 블럭 베어링을 제공코저 하는 것으로서 이를 첨부된 도면을 참조하여 상세히 설명하면 다음과 같다.The present invention is made of a plastic material as disclosed in the prior patent of the present inventors to improve the defects of the pillow-type block bearing made of a metal material composed of the conventional ball bearing as described above, or the pillow-type block bearing which is made of plastic and supplied with oil. And a separate bearing disc in the existing pillow-type block bearing that supplies oil by the oil supply nipple, and then another ball bearing unit installed through the bearing disc to allow the bearing to maximize the bearing effect. It will be described in detail with reference to the accompanying drawings as to provide a type block bearing as follows.

Since it is made of the same material as Enpla, corrosion resistance, impact resistance, and durability are excellent, and the bearing unit 12 is fixed together with the roller shaft 1 'and the bush 10 to rotate, and then ball bearings from the oil supply nipple (3). When the oil injection holes 4, 4 ', 4 "penetrated to the ball 16 of (13) coincide with each other, the oil is injected into the ball 16 of the ball bearing 13 through the oil injection holes. Since the bearing unit 12 is rotated in contact with the bearing disk having good lubricity, the bearing unit 12 is excellent in smoothness and lubricity and thus serves as an excellent bearing with little frictional resistance. When the pillow block bearing of the present invention is applied to a roller shaft in order to transport heavy loads, the bearing unit 12 and the bush of the pillow block bearing of the present invention are connected to the shaft 1 'of the heavy load conveying roller. 10) or by inserting various keys such as buried keys on the roller shaft 1 'and forming grooves on the bushes (not shown here), and operating the rollers, the abrasion resistance of the block bearing body is maintained even at high impact. The bearing unit 12 is fixed to the bearing unit case 11 together with the characteristics of impact resistance, heat resistance, durability and corrosion resistance, so that the sliding unit can smoothly slide while being in contact with the bearing disk 15 having good lubricity. The ball 16 embedded in the ball bearing 13 supplies oil between the bearing case 14 of the bearing unit 12 and the bearing disk 15 while storing and rotating oil, thereby providing lubricity and smoothness. As the degree is further increased, the roller shaft 1 'is rotated very smoothly with little friction by the bearing unit 12.

본 발명 필로형 블럭 베어링은 내충격성, 내마모성, 내열성 및 내부식성 등이 극히 우수한 엔플라나 슈퍼엔플라와 같은 재질로 베어링이 구성되고 그 축받이공 내부에 별개의 볼베어링 유니트(12)가 장착된데다가 오일공급관(4)(4')(4")을 통하여 오일을 공급해주므로 내충격성, 내마모성, 내열성 및 내식성등의 효과와 윤활성이 우수하여 회전력이 극히 양호한 효과가 있다.In the present invention, the pillow block bearing is made of a material such as Enplan or Super Enpla which is extremely excellent in impact resistance, abrasion resistance, heat resistance and corrosion resistance, and a separate ball bearing unit 12 is mounted inside the bearing hole and oil Since oil is supplied through the supply pipes 4, 4 ', and 4 ", it has excellent effects such as impact resistance, abrasion resistance, heat resistance, and corrosion resistance and lubricity, and thus, the rotational force is extremely good.
