본 고안은 양수핌프에 있어서 주축 길이를 길게 연장할때에 사용되는 축연결 구조에 관한 것이다.The present invention relates to a shaft connecting structure used in extending the length of the main shaft in the amniotic pump.

펌핑하여야 할 양수길이(揚程)가 긴 장소에서 사용되는 양수펌프는 원동기의 축(1, 모터축)을 길게 연장 형성하고 이렇게 길게 연장된 축단에 펌프를 장착하게 되어 있는바, 기존에는 양수길이에 알맞는 길이로 연장축(2)을 형성한다음 이 연장축(2)을 규격품으로 만들어진 모터축(1)에 용접(W) 등의 방법으로 고정하여 길이가 긴 펌프축을 형성하고 이렇게 길게 연장 형성된 펌프축의 끝단에 펌핑장치를 장착하여 사용하여 왔다(제1도 참조).Pumping pump used in pumping place where pumping length should be long is long. It extends shaft (1, motor shaft) of prime mover, and pump is installed on shaft length that extends. After the extension shaft 2 is formed to a suitable length, the extension shaft 2 is fixed to the motor shaft 1 made of a standard product by welding (W) or the like to form a long pump shaft. A pumping device has been used at the end of the pump shaft (see Figure 1).

그러나 이와같이 기장이 길게 형성된 펌프축은 사용중 축이 휘거나 뒤틀림이 발생하고 또한 축 하중의 증가로 인하여 베어링이 과열되고 마모되어 수시로 축을 수리하거나 교체하여야 하는 것이나, 연장축을 모터축에 접합할때에 용접과 같은 방법으로 일체적으로 고정하고 있으므로, 모터축(1)으로부터 연장축(2)을 분리할 수 없기 때문에 축을 교체하고자 할 때에는 축만을 교체하지 못하고 모터 전체를 교체하여야 하는 문제점이 있어왔었기에 이와같은 문제점을 해결하고자 본 출원인은 본원 고안의 출원에 선행하여 1996년 5월 3일자로 펌프의 축연결구조에 관하여 새로운 고안(이하 선출원 고안이라 함)을 하였는데 선출원 고안은 모터축에 연장축을 연결하고자 할 때에 제2도에 도시된바처럼 이들 사이를 키와 부싱 원통형커플링을 사용하여 연결 조립하므로서, 펌프의 사용중 축이 마모되거나 변형되었을때에 이를 수리하거나 교체하고자 할 때에는 키와 부싱만을 간단히 분해하면 연장축이 모터축으로부터 용이하게 분리되도록 하여 연장축만을 수리하거나 교체할 수 있도록 하고자 하는 조립과 분해가 용이한 펌프의 축연결구조를 제공한 것인데 이와같은 선출원 고안에 따른 축연결구조는 모터축(1)과 펌프축(2)을 연결함에 있어 부싱(6)으로 연결 조립하므로서 펌프의 사용중 두 축(1,2)과 부싱(6)의 공차로 인하여 펌프축(2) 끝단의 편각이 커져 축 진동이 발생되므로 케이싱의 라이너링 부위의 마모가 심하고, 특히 펌프축(2)과 부싱(6)이 결합된 부분에 사용중 발생된 응력으로 인하여 부식발생이 현저하여 부싱(6)의 분해가 곤란할뿐 아니라 무리한 분해로 인해 모터축(1)에 손상을 줄 염려가 많았었다.However, pump shafts with long lengths, such as bending or twisting of the shaft during use, and bearing overheating and abrasion due to an increase in the shaft load, require frequent repairs or replacement of the shaft. Since the fixing shaft is integrally fixed in the same way, the extension shaft 2 cannot be separated from the motor shaft 1. Therefore, when the shaft is to be replaced, there is a problem that the entire motor must be replaced instead of the shaft. In order to solve the problem, the applicant has made a new design (hereinafter referred to as the design application) on the shaft connection structure of the pump prior to the application of the design of the present application, which is intended to connect the extension shaft to the motor shaft. And as shown in Figure 2, the connection between them using a key and bushing As a result, when the shaft is worn or deformed while the pump is in use, when the shaft is worn or deformed, simply disassembling only the key and the bushing will allow the extension shaft to be easily separated from the motor shaft so that only the extension shaft can be repaired or replaced. The shaft connection structure of the pump which is easy to assemble and dismantle is provided. The shaft connection structure according to the design of the previous application is connected to the bushing (6) to connect the motor shaft (1) and the pump shaft (2). Due to the tolerance between the two shafts (1, 2) and the bushing (6) during use, the angle of the end of the pump shaft (2) increases, causing axial vibration, which causes severe wear on the liner of the casing, especially the pump shaft (2) and bushing. Corrosion is prominent due to the stress generated during use at the part where (6) is combined, which makes it difficult to disassemble the bushing (6) as well as to damage the motor shaft (1) due to excessive disassembly. The.

이와같은 본 고안의 목적을 달성하는 본 고안에 따른 축연결구조는 축과 축을 연결하는 부싱을 선출원 고안의 원통형커플링에서 분할형커플링으로 변경하고 커플링과 두축 사이의 공회전을 방지하기 위하여 고정핀을 장착 형성하여 육각렌치를 사용 좌우 조정하면서 조립하도록 한 것이다.The shaft connection structure according to the present invention to achieve the object of the present invention is to change the bushing connecting the shaft and the axis from the cylindrical coupling of the previous design to the split coupling and fixed to prevent the idle between the coupling and the two shafts The pin was mounted to form a hexagonal wrench while adjusting left and right.

본 고안에 따른 축연결구조에 의한 모터축(1)과 펌프축(2)을 연결 조립함은 제3도에 도시된바와 같이 반구형으로 2단의 홈이 각각 형성된 2개의 분할커플링(600, 600')과 2개의 고정핀(P, P') 그리고 4개의 육각 렌치볼트(B, B') 및 육각너트(N, N')로 구성되는데 상기 두 분할커플링(600, 600')에는 제4도, 제5도, 제6도에 도시된바처럼 서로 대칭구조로서 서로 접하는 면에 반구형홈으로 된 축삽입홈인 펌프축삽입홈(601, 601')과 모터축삽입홈(602, 602')이 계단상으로 형성되고 펌프축삽입홈(601, 601') 및 모터축삽입홈(602, 602')의 천정면에는 상기 고정핀(P, P')이 끼워 넣어지는 고정핀 조립홈(Ph, Ph')이 각각 형성되어 있다.Connecting and assembling the motor shaft (1) and the pump shaft (2) by the shaft connection structure according to the present invention is divided into two split couplings (600, 600 '), two fixing pins (P, P'), four hexagon wrench bolts (B, B ') and hexagon nuts (N, N'), and the two split couplings (600, 600 ') As shown in FIG. 4, FIG. 5, and FIG. 6, the pump shaft insertion grooves 601, 601 'and the motor shaft insertion grooves 602, which are shaft insertion grooves of hemispherical grooves on surfaces which are in symmetrical structure and are in contact with each other, as shown in FIGS. 602 ') is formed in a stepped shape, and a fixing pin assembly in which the fixing pins P and P' are fitted into the ceiling surfaces of the pump shaft insertion grooves 601 and 601 'and the motor shaft insertion grooves 602 and 602'. Grooves Ph and Ph 'are formed, respectively.

그리고 두 분할커플링(600, 600')이 일체로 조립할 때 서로 접하는 부분에는 제3도, 제4도, 제5도, 제6도에 도시된바처럼 각 커플링(600, 600') 두 개의 관통구멍이 형성되는데 이것은 볼트삽입구로서 육각렌치볼트삽입구(Bh, Bh')인 것인데 이와 같은 육각렌치볼트삽입구(Bh, Bh')는 각 커플링에 4개가 형성되어 있다.In addition, when the two split couplings 600 and 600 'are integrally assembled, each of the couplings 600 and 600' includes two coupling parts 600 and 600 'as shown in FIGS. 3, 4, 5, and 6, respectively. Four through holes are formed, which are hexagonal wrench bolt insertion holes (Bh, Bh ') as bolt insertion holes, and four hexagonal wrench bolt insertion holes (Bh, Bh') are formed at each coupling.

그리고 본 고안에 따른 축연결구조를 이루는 모터축(1)과 펌프축(2)에는 두축이 서로 접하는 부위의 적절한 위치에 축을 가로 지르는 원통상의 관통구가 각각 형성되는데 이 관통구는 고정핀삽입구(1Po, 2Po)인 것이다.And the motor shaft (1) and the pump shaft (2) constituting the shaft connecting structure according to the present invention is formed in each of the cylindrical through-holes transverse to the shaft at the appropriate position of the portion where the two shafts contact each other, the through-hole is fixed pin insertion hole ( 1Po, 2Po).

이상과 같은 구성으로 이루어진 본 고안에 따른 축연결구조에 의한 축연결 조립상태를 살펴보면 제4도에 도시된바처럼 모터축(1)과 펌프축(2)을 서로 연립하고 여기에 두 분할커플링(600, 600')으로 연결하도록 하는데 두 개의 고정핀(P, P')를 모터축(1)과 펌프축(2)의 고정핀삽입구(1Po, 2Po)에 삽입하여 그 양단이 두 분할커플링(600, 600')의 축삽입홈(601, 601', 602, 602')에 형성된 고정핀조립홈(Ph, Ph')에 각각 끼워넣도록 하고 두 분할커플링(600, 600')에 형성된 서로 대향하는 육각 렌치볼트삽입구(Bh, Bh')를 서로 연통하도록 하여 여기에 각각 육각렌치볼트(B, B')를 각각 삽입하여 육각너트(N, N')로 조이면 두 분할커플링(600, 600')에 의하여 모터축(1)과 펌프축(2) 함께 연동되도록 조립되는 것이다.Looking at the assembly state of the shaft connection by the shaft connection structure according to the present invention having the configuration as described above as shown in Figure 4 the motor shaft (1) and the pump shaft (2) in a row and two split coupling here (600, 600 '), two fixing pins (P, P') are inserted into the fixing pin insertion holes (1Po, 2Po) of the motor shaft (1) and the pump shaft (2) so that both ends of the two split couples Two split couplings 600 and 600 'are inserted into the fixing pin assembly grooves Ph and Ph' formed in the shaft insertion grooves 601, 601 ', 602 and 602' of the rings 600 and 600 ', respectively. Hex wrench bolt insertion holes (Bh, Bh ') formed in each other to communicate with each other, and hex wrench bolts (B, B') are respectively inserted therein and tightened with hexagon nuts (N, N '). The motor shaft (1) and the pump shaft (2) are assembled together by (600, 600 ').

이와같은 구성 및 작용으로 이루어진 본 고안에 따른 축연결구조를 사용하여 모터축과 펌프축을 연결하게 되면 상술한바와 같이 분할되는 커플링과 육각렌치볼트를 사용하므로 분해와 조립시에 별도의 기술이 필요하지 않고 조립 및 분해작업이 매우 간단하며 더욱이 커플링과 축 사이의 결합이 고정핀으로 견고하게 조립되도록 하므로 선출원 고안과 달리 축과 커플링 사이에 발생될 수 있는 공회전이 발생될 우려가 전혀 없다할 것이므로 모터축의 동력을 펌프축에 100% 전달할 수 있을뿐 아니라 펌프축의 끝단에 공차발생 우려가 전혀없어 국부적으로 편차응력이 발생되어 연결부분에 부식이 조장될 우려가 전혀 없어졌다 할 것이다.When connecting the motor shaft and the pump shaft using the shaft connection structure according to the present invention made up of such a configuration and action, a separate technology is required when disassembling and assembling because the coupling and the hexagonal wrench bolts are divided as described above. The assembly and disassembly work is very simple, and furthermore, the coupling between the coupling and the shaft is firmly assembled by the fixing pin, so there is no danger of idling that may occur between the shaft and the coupling unlike the original design. Therefore, it is possible to transmit 100% of the power of the motor shaft to the pump shaft, and there is no fear of tolerances at the end of the pump shaft, so there is no fear of corrosion of the connection part due to local deviation stress.
