본 고안은 동력전달용 커플링장치에 관한 것으로, 특히 동력전달이 확실하게 이루어짐은 물론, 분해가 간편하여 구동축커플링과 종동축커플링사이에 개재되는 완충재를 용이하게 교환할 수 있도록 된 커플링장치에 관한 것이다.The present invention relates to a power transmission coupling device, and in particular, the power transmission is not only made sure, but also easy to disassemble coupling coupling that can easily exchange the buffer material between the drive shaft coupling and the driven shaft coupling Relates to a device.
일반적으로 커플링장치(Coupling device)는 펌프에 모터를 연결시킬때와 같이 2축 연결장치로서 수리나 교환이 편리하고, 축간의 충격하중감소와 과부하에 대한 보호 및 회전진동저감의 잇점이 있기 때문에 기계장치에 널리 사용되고 있다.In general, the coupling device is a two-axis coupling device, such as when connecting a motor to a pump, which is convenient to repair or replace, and has advantages of reducing impact load between shafts, protecting against overload, and reducing rotational vibration. Widely used in machinery.
이러한 종래의 커플링장치를 사용하여 예컨대 대용량의 펌프와 구동마력이 높은 모터를 연결시킬 때에는 제 4 도에 도시된 바와 같이, 먼저 취급하기 힘든 펌프와 모터를 지지대등에 견고하게 장착시켜 펌프축인 종동축(41)과 모터축인 구동축(42)을 서로 일직선상으로 정렬시킨 상태에서 각 축(41, 42)에 형성된 키이홈(43)에 키이(44)를 끼우고, 상기 축(41, 42)의 외경과 거의 동일하면서 내면에 키이(44)와 일치되는 키이홈(45)이 형성된 플랜지(46)를 해머등으로 타격하여 억지끼워 맞추고 나서, 상기 각각의 플랜지(46)와의 사이에 고무로된 완충재(47)를 끼운 다음, 상기 플랜지(46)의 공회전을 방지하기 위해 플랜지몸체에서 키이홈(45)까지 관통된 나사구멍에 조임용볼트(48)에 죄어 2축을 서로 연결시키도록 되어 있다.When connecting a large capacity pump and a high driving horsepower motor using such a conventional coupling device, for example, as shown in FIG. The key 44 is inserted into the key groove 43 formed in each of the shafts 41 and 42 in a state in which the coaxial 41 and the driving shaft 42 which are the motor shafts are aligned in a straight line with each other. After hitting the flange 46 with the key groove 45 corresponding to the key 44 on the inner surface of the inner diameter substantially equal to the outer diameter of the crankshaft with a hammer or the like, a rubber between each of the flanges 46 is used. After the cushioning material 47 is inserted, the two screws are connected to each other by being fastened to the fastening bolts 48 to the threaded holes penetrated from the flange body to the key groove 45 to prevent idling of the flange 46. .
그런데 상기 플랜지(46)사이에 개재되는 완충재는 대개 고무로 되어 있어 마모가 쉽고 변형도 자주 일어나 정기적으로 교환을 해주어야 하는데, 이 경우 모터와 펌프는 각각 지지대등에 견고하게 장착되어 취급하기 어렵기 때문에 커플링을 분해시켜 완충재를 교환해 주고 있다.By the way, the cushioning material interposed between the flanges 46 is usually made of rubber, so wear is easy and deformation occurs frequently and should be replaced regularly. In this case, the motor and the pump are each firmly mounted on a support, and thus are difficult to handle. Disassemble the ring and replace the cushioning material.
즉, 모터나 펌프축에 장착된 플랜지의 조임용볼트를 풀고 해머등과 같은 공구를 이용하여 모터나 펌프축으로부터 커플링장치를 분해하거나 커플링플랜지사이의 틈에 보조공구를 끼워 이격시키고서 완충재를 교환하여 왔지만, 이러한 일련의 과정을 거치면서 커플링장치나 축에 손상을 줄 우려가 있을 뿐 아니라 용량이 큰 대형모터일 경우에는 많은 부대장비가 필요하게 되고 완충재의 교환에도 다수의 원인을 필요로 하게 되는 문제점이 있었다.In other words, loosen the bolt for tightening the flange attached to the motor or pump shaft and use a tool such as a hammer to disassemble the coupling device from the motor or pump shaft, or insert the auxiliary tool in the gap between the coupling flanges However, this series of processes may damage the coupling device or shaft, and in the case of large motors with large capacity, many additional equipments are needed and many causes are required for the replacement of shock absorbers. There was a problem done with.
또 상기 완충재를 교환한 후에 구동축과 종동축을 재결합시키려면 2축을 동일축선을 이루도록 정렬하는데, 이같은 작업은 숙련자가 아니면 정확한 축선 정렬이 어렵고, 만일 2축이 일직선으로 정확히 정렬되지 않으면 진동이 발생될 뿐 아니라 완충재의 마모와 손상이 크고, 이로 인하여 2축간의 동력전달이 정확하게 이루어지지 못할 뿐만 아니라 심한 경우에는 모터나 펌프의 베어링 및 그 외의 부품이 소착(燒着)되게 되는 문제점이 있었다.In order to recombine the drive shaft and the driven shaft after replacing the cushioning material, the two axes are aligned to form the same axis. This operation is difficult to align the exact axis unless an expert is experienced. If the two axes are not aligned in a straight line, vibration may occur. In addition, the wear and damage of the cushioning material is large, and this causes power transmission between the two axes not to be made accurately, and in severe cases, there is a problem in that the bearings and other parts of the motor or the pump are deposited.
이에 본 고안은 상기한 문제점을 해소하기 위해 안출된 것으로, 구동부와 종동부가 동일축선상에 일치되게 정렬된 상태에서 2축 연결 및 분리가 용이할 뿐만 아니라 충격완화용으로 개재되는 완충재도 용이하게 교환시킬 수 있도록 된 동력전달용 커플링장치를 제공함에 그 목적이 있다.The present invention has been devised to solve the above problems, and the two-axis connection and separation is easy in the state in which the driving unit and the follower are aligned on the same axis, as well as the shock absorbing material intervening for shock mitigation. It is an object to provide a power transmission coupling device that can be exchanged.
상기 목적을 달성하기 위한 본 고안은, 구동축과 종동축에 각각 키이홈이 형성되면서 이 키이홈에 키이가 끼워지고, 원판형상으로서 원주방향을 따라 한쪽면에 다수의 조오가 소정간격을 두고 돌출형성된 플랜지판과 이 플랜지판의 다른쪽면에 원통형상으로서 나사구멍이 관통형성된 플랜지몸체가 일체로 형성되어 이루어진 플랜지가 상기 축에 각각 끼워져 나사구멍에 체결되는 고정용볼트로 고정됨과 더불어 이들 플랜지사이에 완충재가 개재되어 서로 맞물려져 2축을 연결시키도록 된 커플링에 있어서, 상기 플랜지가 축에 끼워지는 내면이 경사지게 형성되고, 원통형상으로서 길이방향을 따라 소정간격을 두고 절단되어 상기 키이에 끼워지는 키이슬릿과 한쪽 끝 외면에 형성된 나사부 및 이 나사부로부터 외면이 플랜지 내경 만큼 점차로 확경되어져 형성된 테이퍼부를 갖춘 슬리이브가 상기 플랜지의 테이퍼내면에 끼워지며, 상기 나사부에는 키이슬릿을 오므리도록 하는 조임용너트가 체결되도록 되어 있다.The present invention for achieving the above object, the key groove is formed in the drive shaft and the driven shaft, respectively, the key is fitted into the key groove, a plurality of jaws on one side along the circumferential direction as a disk shape protruded with a predetermined interval. The flange plate and the flange body formed by integrally forming a flange body through which a threaded hole is formed on the other side of the flange plate are fixed by fixing bolts which are respectively fitted to the shafts and fastened to the screw holes, and cushioning material between these flanges. In the coupling which is interlocked with each other to connect the two shafts, the inner surface on which the flange is fitted to the shaft is formed to be inclined, cut into the cylindrical shape at a predetermined interval along the longitudinal direction and fitted to the key. And the thread formed on the outer surface of one end and the outer surface is gradually expanded from the threaded portion by the flange inner diameter. A sleeve having a tapered portion formed therein is fitted to the inner surface of the taper of the flange, and a tightening nut for fastening the key slit is fastened to the screw portion.
이하 본 고안을 첨부된 예시도면에 의거 상세히 설명한다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.
제1도는 본 고안에 따라 구성된 커플링의 분리사시도인 바, 구동축(1)상에 형성된 키이홈(2)에 일치되는 키이(3)가 끼워지고, 이 구동축(1)에 커플링(4)이 결합되는 바, 이 커플링(4)은, 3개의 조오(5)가 구비된 플랜지판(6)과 원형의 외주면에 고정용볼트(7)가 결합되면서 일정한 내경이 형성된 플랜지몸체(8)를 갖춘 플랜지(9)와, 이 플랜지(9)내경에 끼워지는 슬리이브(10) 및, 이 슬리이브(10)를 조이면서 플랜지(9)를 밀어주어 구동축(1)에 결합시키도록 된 조임용너트(12)로 구성되어져 있다.1 is an exploded perspective view of a coupling constructed according to the present invention, in which a key 3 corresponding to a key groove 2 formed on a drive shaft 1 is fitted, and the coupling 4 is fitted to the drive shaft 1. The coupling 4 is a flange body 8 having a constant inner diameter while the fixing plate 7 is coupled to a flange plate 6 provided with three jaws 5 and a circular outer circumferential surface thereof. Flange (9) having a flange, a sleeve (10) fitted to the inner diameter of the flange (9), and a jaw configured to push the flange (9) to engage the drive shaft (1) while tightening the sleeve (10). It is composed of a lead nut (12).
또 슬리이브(10)에는 제2도에 도시된 바와 같이, 구동축(1)에 끼워진 키이(3)를 통과하면서 끼워지도록 슬리이브(10) 길이전체에 소정간격으로 절단된 키이슬릿 (13)이 형성되어 있고, 슬리이브(10)의 한쪽 끝 부위에는 조임용너트(12)가 결합되어 축에 끼워진 슬리이브(10)를 조일 수 있도록 나사부(14)가 형성되어 있으며, 이 나사부(14)를 제외한 슬리이브(10)의 몸체에는 나사부(14)로부터 점차 외경이 확장된 테이퍼부(15)가 형성되어 있지만, 내경은 구동축(1)과의 결합을 위해 동일하게 되어 있고, 더불어 이러한 테이퍼부(15)가 상기 플랜지(9)의 내면에서 정확히 물리도록 플랜지(9)의 내면도 동일한 각도로 테이퍼져 형성되게 된다.In addition, as shown in FIG. 2, the sleeve 10 includes a key slit 13 cut at predetermined intervals throughout the length of the sleeve 10 so as to be fitted while passing through the key 3 fitted to the drive shaft 1. The threaded portion 14 is formed at one end of the sleeve 10 so that the fastening nut 12 is coupled to the sleeve 10 to tighten the sleeve 10 fitted to the shaft. In the body of the sleeve 10 except for the tapered portion 15 is formed with the outer diameter gradually expanded from the threaded portion 14, the inner diameter is the same for coupling with the drive shaft 1, and in addition, such a tapered portion ( The inner surface of the flange 9 is also tapered at the same angle so that 15 is correctly snapped on the inner surface of the flange 9.
한편, 상기 구동축(1)의 커플링(4)과 결합되는 종동축(11)의 커플링(4)도 동일한 구성으로 되어져 있지만, 단지 조오(5) 사이의 플랜지판(6)상에 상기 고정용볼트(7)를 끼워 돌려서 대향 플랜지(9)를 밀어 분리시키기 위해 해체용볼트구멍(16)이 관통·형성되어져 있으며, 이와 같이 구성된 종동축커플링(4)과 구동축커플링(4)의 결합시에는 각각의 조오(5) 사이에 충격흡수 및 기밀한 맞물림을 위해 고무로 된 완충재(17)를 끼워 사용하게 된다.On the other hand, although the coupling 4 of the driven shaft 11 coupled with the coupling 4 of the drive shaft 1 has the same configuration, it is only fixed on the flange plate 6 between the jaws 5. A dismantling bolt hole 16 is formed through and formed in order to slide the bolt 7 and push the opposing flange 9 to separate the driven shaft coupling 4 and the drive shaft coupling 4. At the time of coupling, rubber cushioning material 17 is sandwiched between the jaws 5 for shock absorption and airtight engagement.
상기한 구성으로 된 커플링(4)의 결합은 제3도에 도시돤 바와 같이, 먼저 축(1, 11)의 외경을 통과하면서 조임용너트(12)가 끼워지고 이어 플랜지(9)가 다시 축(1, 11)에 끼워지며, 축에 끼워져 있는 키이(3)를 따라 키이슬릿(13)이 갖추어진 슬리이브(10)를 밀어 넣게 되는데, 대응되는 축(11, 1)상에도 동일한 순서로 결합되어서, 상기 플랜지 조오(5)사이에 완충재(17)를 끼운 후, 슬리이브(10)에 형성된 나사부(14)를 매개로 조임용너트(12)를 결합시키어 완전히 조이게 되는 바, 이 조임용너트(12)는 플랜지(9)를 대응되는 플랜지(9)쪽으로 밀면서 슬리이브(10)가 축(1, 11) 중심방향으로 조이도록 하는 역할을 한다. 이어서 플랜지(9) 몸체에 끼워진 고정용볼트(7)로 키이(3)가 조여지게 되면 플랜지(9)의 테이퍼면과 슬리이브(10)의 테이퍼부(15)가 면접촉하게 되고, 축 (1 11)상에서 정확히 위치결정됨과 더불어 완충재(17)가 물리면서 정위치에 놓이게 된다.Coupling of the coupling 4 having the above-described configuration is performed as shown in FIG. 3. First, the tightening nut 12 is fitted while passing through the outer diameters of the shafts 1 and 11, and then the flange 9 is again fitted. The sleeve 10, which is fitted to the shafts 1 and 11, is pushed along the key 3, which is fitted to the shaft, with the sleeve 10 provided with the key slit 13, and the same order is applied to the corresponding shafts 11 and 1, respectively. When the cushioning material (17) is sandwiched between the flange jaws (5), the tightening nut (12) is coupled through the threaded portion (14) formed in the sleeve (10), and then tightened completely. The appointment nut 12 serves to tighten the sleeve 10 toward the center of the shafts 1 and 11 while pushing the flange 9 toward the corresponding flange 9. Subsequently, when the key 3 is tightened with the fixing bolt 7 fitted to the flange 9 body, the tapered surface of the flange 9 and the tapered portion 15 of the sleeve 10 are brought into surface contact, and the shaft ( In addition to being correctly positioned on 1 11), the cushioning material 17 is snapped into position.
상기와 같이 구성된 본 고안 커플링장치는, 잦은 교환이 요구되는 완충재(17)를 교체시에도 모터나 펌프를 해체하지 않아도 되는 바, 즉 간단히 종동축플랜지조오(5) 뒷쪽면에 형성된 해체용볼트구멍(16)에 고정용볼트(7)를 끼운 다음, 구동축슬리이브 (10)상의 조임용너트(12)를 약간만 풀고서 상기 볼트(7)를 회전시키면 구동축플랜지(9)가 밀리면서 슬리이브(10)의 테이퍼부(15)와 플랜지의 내면에 형성된 테이퍼면의 접촉은 분리되어 헐거워지고, 이어 종동축플랜지(9)의 조임용너트(12)를 풀고서 구동축플랜지(9)의 고정용볼트(7)를 죄어놓고서 상기 고정용볼트(7)를 계속회전시키면 상기 구동축플랜지(9)는 구동축조임용너트(12)로 지지되어 종동축플랜지(9)에 반력을 주면서 종동축플랜지(9) 내면에 끼워져 있는 슬리이브(10)의 테이퍼부(15)에서 이격되어 종동축플랜지(9)는 헐거워지게 된다.The coupling device of the present invention configured as described above does not require dismantling of a motor or a pump even when replacing a shock absorbing material 17 requiring frequent replacement, that is, a dismantling bolt formed on the rear surface of a driven shaft flange flange 5. Insert the fixing bolt (7) into the hole (16), loosen the tightening nut (12) on the drive shaft sleeve (10) slightly, and rotate the bolt (7). The drive shaft flange (9) pushes the sleeve The contact between the tapered portion 15 of the taper portion 10 and the tapered surface formed on the inner surface of the flange is separated and loosened. Then, the fastening nut 12 of the driven shaft flange 9 is loosened to fix the drive shaft flange 9. When the fixing bolt 7 is rotated while the bolt 7 is tightened, the drive shaft flange 9 is supported by the drive shaft tightening nut 12 to give the driven shaft flange 9 a reaction force while the driven shaft flange 9 ) Driven by spaced apart from the tapered portion 15 of the sleeve 10 fitted to the inner surface Flange 9 becomes loose.
이렇게 헐거워진 플랜지(9)의 조임용너트(12)를 완전히 풀어 서로 이격시키고 나면 손상된 완충재(17)를 손쉽게 빼내어 다른 완충재로 용이하게 교환할 수 있게 되고, 상기한 결합순서로 결합하게 되면 쉽게 동력전달용 커플링(4)의 중심축은 자연히 일치되면서 결합이 완성되게 된다.Once the loosening nuts 12 of the loosened flange 9 are completely removed and spaced from each other, the damaged shock absorbing material 17 can be easily removed and easily replaced with another shock absorbing material. The central axis of the transmission coupling 4 naturally coincides and the coupling is completed.
이상 설명한 바와 같이 본 고안에 의하면, 상기 완충재(17)의 교환은 모터나 펌프를 분리하지 않으면서도 손쉽게 이루어지는 한편, 커플링(4)의 결합은 조임용너트(12)로 체결력을 부여하면서 고정용볼트(7)로 공회전을 방지하게 됨으로써 커플링 원래의 목적인 정확한 동력전달은 물론 완충재(17)의 교환시, 모터나 펌프를 분리시키지 않아도 됨에 따라 축중심은 흐트러지지 않게 되고 비숙련자라도 손쉽게 완충재를 교환후, 결합시킬 수 있는 효과가 있다.As described above, according to the present invention, the shock absorbing material 17 is easily replaced without removing a motor or a pump, while the coupling 4 is coupled to the fastening nut 12 for fastening while providing a fastening force. By preventing the idling with the bolt (7), as well as the exact power transmission of the coupling original purpose, as well as the need to remove the motor or pump when replacing the shock absorbing material 17, the axis of the center will not be disturbed, even non-skilled personnel can easily After exchange, there is an effect that can be combined.
