본 고안은 베어링 분해/조립용 지그에 관한 것으로서, 베어링 전체에 균일한 압력을 가하여 분해 또는 조립시킴으로써 베어링 수명을 연장시키고 부품의 손상을 방지하여 재활용을 가능하게 하는 베어링 분해/조립용 지그에 관한 것이다.The present invention relates to a jig for disassembling / assembling a bearing, and to a jig for disassembling / assembling a bearing, which can be recycled by extending the bearing life and preventing damage to parts by disassembling or assembling by applying a uniform pressure to the whole bearing. .

일반적으로 도 1에 도시된 바와 같이, 샤프트를 회전가능하게 지지하는 케이 싱(10)에는 샤프트의 원활한 회전을 위하여 베어링(20)이 결합된다.In general, as shown in Figure 1, the casing 10 for rotatably supporting the shaft is coupled to the bearing 20 for smooth rotation of the shaft.

베어링(20)의 결합은 통상 케이싱의 결합공을 가열하여 팽창시킨 다음 베어링(20)을 결합시키는 열박음공정으로 결합시킨다.Coupling of the bearing 20 is usually combined by a shrink fit process that heats and expands the coupling hole of the casing and then combines the bearing 20.

그러나 이와 같은 열박음은 케이싱(10)의 결합공에 베어링(20)이 불균일한 압력으로 결합되게 되어서 즉, 비스듬히 결합되어 편마모되는 등 베어링 수명이 단축되는 문제점이 있다.However, this shrinkage has a problem that the bearing 20 is coupled to the coupling hole of the casing 10 at an uneven pressure, that is, the bearing life is shortened, such as being obliquely coupled to wear.

또한, 케이싱(10)으로부터 베어링(20)을 분해시에도 불균일한 압력으로 베어링을 취출하므로서, 리테이너와 같은 변형되기 쉬운 부품의 재활용이 곤란해진다.In addition, even when the bearing 20 is disassembled from the casing 10, the bearing is taken out at a non-uniform pressure, thereby making it difficult to recycle deformable parts such as retainers.

본 고안은 상기와 같은 문제점을 해결하기 위하여 안출된 것으로써, 케이싱의 결합공으로부터 베어링의 손상을 최소화하면서 취출해내거나 결합시킬 수 있도록 한 베어링 분해/조립용 지그를 제공하는 데 그 목적이 있다.An object of the present invention is to provide a bearing disassembly / assembly jig that can be taken out or combined while minimizing damage to a bearing from a coupling hole of a casing.

본 고안의 다른 목적은, 베어링에 균일한 압력을 제공하여 케이싱에 결합시키거나 분리해낼 수 있도록 한 베어링 분해/조립용 지그를 제공하는 데 있다.Another object of the present invention is to provide a bearing disassembly / assembly jig which provides a uniform pressure to the bearing so that it can be coupled to or detached from the casing.

상기 목적을 달성하는 본 고안은 케이싱의 결합공에 베어링을 결합시키거나 결합공으로부터 베어링을 분리해내는 베어링 분해/조립용 지그에 있어서,The present invention to achieve the above object is in the bearing disassembly / assembly jig for coupling the bearing to the coupling hole of the casing or to separate the bearing from the coupling hole,

상기 베어링은 내륜과 외륜 및 보올을 구비하며,The bearing has an inner ring, an outer ring and a bowl,

상기 베어링의 내륜에 결합되는 결합블럭과, 상기 결합블럭으로부터 연장형성되며 상기 베어링의 내륜과 외륜의 단면에 밀착되는 밀판과, 상기 밀판에 결합되 는 실린더로드를 가지며 압력을 가하는 실린더를 구비하여 된 것을 특징으로 한다.A coupling block coupled to the inner ring of the bearing, a compact plate extending from the coupling block and tightly attached to end surfaces of the inner ring and the outer ring of the bearing, and a cylinder rod coupled to the close plate to apply pressure to the cylinder; It is characterized by.

또한, 본 고안 지그에 있어서, 상기 실린더로드와 밀판은 착탈가능하게 나사결합된 것을 특징으로 한다.In addition, in the jig of the present invention, the cylinder rod and the sealing plate is characterized in that the detachably screwed.

상기 본 고안의 특징에 의하면, 본 고안 지그는 결합블럭 및 밀판에 의해서 베어링에 균일한 압력 제공이 가능하게 됨으로써 베어링을 손상시키기지 아니하고 분해 및 조립을 가능하게 한다.According to the features of the present invention, the jig of the present invention is able to provide a uniform pressure to the bearing by the coupling block and the sealing plate, thereby enabling the disassembly and assembly without damaging the bearing.

또한, 실린더로드에 밀판이 나사결합됨으로써 베어링 사이즈에 대응되는 결합블럭 및 밀판으로의 교체 사용을 가능하게 한다.In addition, the screw plate is screwed to the cylinder rod to enable the use of the replacement block and the mating plate corresponding to the bearing size.

이하 첨부된 도면을 참조하면서 본 고안에 따른 바람직한 실시예를 상세히 설명한다. Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

본 고안 실시예의 지그는 도 3에 도시된 바와 같이 케이싱(10)의 결합공으로부터 베어링(20)을 분리해내거나, 도 4에 도시된 바와 같이 결합공에 베어링(20)을 결합시키는 데 사용된다.The jig of the embodiment of the present invention is used to separate the bearing 20 from the coupling hole of the casing 10 as shown in FIG. 3, or to couple the bearing 20 to the coupling hole as shown in FIG. .

상기 베어링(20)은 내륜(21)과 외륜(22) 및 보올(23)을 구비하며, 보올(23)은 통상과 마찬가지로 리테이너에 의해서 일정간격 유지되도록 지지된다.The bearing 20 includes an inner ring 21, an outer ring 22, and a bowl 23, and the bowl 23 is supported to be maintained at a constant interval by a retainer as usual.

본 고안 실시예의 지그(30)는 도 2를 참조하면, 상기 베어링(20)의 내륜에 결합되는 결합블럭(34)과, 상기 결합블럭(34)으로부터 연장형성되며 상기 베어링(20)의 내륜(21)과 외륜(22)의 단면에 밀착되는 밀판(33)과, 상기 밀판(33)에 결합되는 실린더로드(32)를 가지며 압력을 가하는 실린더(31)를 구비한다.2 is a coupling block 34 coupled to an inner ring of the bearing 20 and an inner ring of the bearing 20 extending from the coupling block 34. 21 and a cylinder 31 in close contact with the end face of the outer ring 22, and a cylinder 31 for applying pressure to the cylinder rod 32 coupled to the seal plate 33.

또한, 상기 실린더로드(32)와 밀판(33)은 착탈가능하게 나사결합되어서, 베 어링(20)의 사이즈에 대응되는 결합블럭(34) 및 밀판(33)으로 교체사용할 수 있게 한다.In addition, the cylinder rod 32 and the plate 33 is detachably screwed, so that it can be replaced with a coupling block 34 and the plate 33 corresponding to the size of the bearing 20.

상기와 같은 지그(30)를 이용한 베어링(20)의 분리작업은 도 3에 도시된 바와 같이, 결합블럭(34)을 내륜(21)에 결합시키고(이때 밀판(33)은 베어링(20)의 내륜(21)과 외륜(22)의 일면에 동시 접촉지지된다)실린더(31)를 작동하여 가압시키면서 케이싱(10)으로부터 베어링(20)을 취출해낸다. 이때 베어링(20)의 내륜(21)과 외륜(22)에는 밀판(33)에 의해서 동일한 압력이 가해지게 되므로 비틀림이 없이 취출되게 된다.Separation of the bearing 20 using the jig 30 as described above, as shown in Figure 3, the coupling block 34 is coupled to the inner ring 21 (in this case, the mill 33 is the bearing of the bearing 20) The bearing 20 is taken out from the casing 10 while operating and pressurizing the cylinder 31 which is simultaneously brought into contact with one surface of the inner ring 21 and the outer ring 22. At this time, since the same pressure is applied to the inner ring 21 and the outer ring 22 of the bearing 20 by the plate 33, it is taken out without twisting.

또한, 케이싱(10)에 베어링(20)을 결합시키는 방법은 분해와 유사한 방법으로, 도 4에 도시된 바와 같이 결합블럭(34)을 내륜(21)에 결합시키고 실린더(31)를 작동하여 결합시킨다. 이때 마찬가지로 밀판(33)은 베어링(20)의 내륜(21)과 외륜(22)의 일면에 동시 접촉지지되어 균일한 압력이 가해지게 되므로 베어링(20)의 손상을 최소화할 수 있게 한다.In addition, the method of coupling the bearing 20 to the casing 10 is a method similar to disassembly, as shown in FIG. 4, the coupling block 34 is coupled to the inner ring 21 and the cylinder 31 is operated to engage it. Let's do it. In this case, the plate 33 may be simultaneously supported by one surface of the inner ring 21 and the outer ring 22 of the bearing 20 to be uniformly applied, thereby minimizing damage to the bearing 20.

상기와 같은 본원 고안은 상기 본원의 정신과 범위를 이탈함이 없이 상기 실시예에 한정되지 아니하고 많은 변형을 가하여 실시될 수 있다.The present invention as described above is not limited to the above embodiments without departing from the spirit and scope of the present application can be carried out by adding a number of modifications.

상술한 바와 같은 본 고안 지그는 결합블럭 및 밀판에 의해서 베어링에 균일한 압력 제공이 가능하게 됨으로써 베어링을 손상시키기지 아니하고 분해 및 조립을 가능하게 한다. 이에 따라서 리테이너 등의 변형을 방지하여 재활용을 가능하게 한다.The jig of the present invention as described above is able to provide a uniform pressure to the bearing by the coupling block and the sealing plate, thereby enabling the disassembly and assembly without damaging the bearing. This prevents deformation of the retainer and the like, thereby enabling recycling.

또한, 실린더로드에 밀판이 나사결합됨으로써 베어링 사이즈에 대응되는 결합블럭 및 밀판으로의 교체 사용을 가능하게 한다.In addition, the screw plate is screwed to the cylinder rod to enable the use of the replacement block and the mating plate corresponding to the bearing size.
