Description

감속기가 내장된 기어펌프{A gear pump with reduction gear}Gear pump with reduction gear {A gear pump with reduction gear}

본 고안은 감속기가 내장된 기어펌프에 관한 것으로, 더욱 상세하게는 펌프의 외부에 구동모터와 연결 장착되는 감속기를 펌프 내부로 내장시켜 감속기 구입에 따른 비용을 절감하고, 구동모터와 펌프를 감속기로 연결하는데 드는 작업시간을 단축할 뿐만 아니라, 좁은 공간에서도 펌프를 구동시킬 수 있는 감속기 내장 기어펌프에 관한 것이다.The present invention relates to a gear pump with a built-in reducer, and more particularly, to reduce the cost of purchasing a reducer by installing a reducer mounted inside the pump connected to a drive motor outside the pump, and converting the drive motor and the pump into a reducer. The present invention relates to a gear pump with a reducer capable of driving the pump in a narrow space as well as shortening the working time required for the connection.

일반적으로 기어펌프는 회전축에 장착된 구동 기어의 회전으로 구동 임펠러가 회전하게 되고, 상기 구동기어와 맞물려 있는 종동 기어가 동시에 회전함으로써 종동 임펠러도 구동 임펠러와 맞물려 회전하게 되는데, 상기 펌프를 구동하기 위해서는 구동모터와 감속기가 필요하며, 상기 구동모터와 감속기 및 펌프를 카플링으로 각각 체결한 후, 펌프를 구동시키면 회전축의 회전이 가능하게 된다.In general, a gear pump rotates a driving impeller by rotation of a driving gear mounted on a rotating shaft, and a driven impeller also rotates at the same time as a driven gear meshed with the driving gear rotates in engagement with a driving impeller. The drive motor and the reducer are required, and after coupling the drive motor, the reducer and the pump with a coupling, respectively, the pump can be driven to rotate the rotation shaft.

따라서 상기 감속기 구입에 따른 비용과 구동모터와 감속기 및 펌프를 연결하는데 필요한 부속품들의 구입에 따른 비용도 많이 소요되고, 각 장치를 연결 장착하는데 따른 번거러움과 장착에 따른 시간 소요로 인하여 펌프의 구동 효율성이 저하되는 등의 여러가지 폐단이 있었다.Therefore, the cost of purchasing the reducer and the cost of purchasing the accessories necessary for connecting the drive motor, the reducer, and the pump are high, and the driving efficiency of the pump is increased due to the cumbersome and time-consuming installation of each device. There were various closures such as deterioration.

본 고안은 이와같은 문제점을 감안하여 안출한 것으로, 구동모터와 연결되는 회전축에 헬리컬로 성형하고, 상기 헬리컬을 펌프 내부의 일측에 장착되어 있는 감속기와 맞물리게 장착함으로써, 모터와 펌프를 연결하는 별도의 감속기가 필요 없으며, 좁은 공간에서도 모터만 연결하여 작동이 가능할 뿐만 아니라, 구동모터와 감속기 및 펌프를 연결하는데 필요한 부속장비와 감속기와 모터 연결시 필요한 부속장비를 별도로 구입할 필요가 없어 장비구입에 따른 비용을 최대한 절감할 수 있는 감속기가 내장된 펌프를 제공코자 하는데 그 목적이 있다.The present invention has been devised in view of such a problem, and is formed by a helical on a rotating shaft connected to a drive motor, and the helical is mounted in engagement with a reducer mounted on one side of the pump, thereby connecting a motor and a pump. It is not necessary to reduce gear, and it is possible to operate by connecting only a motor in a narrow space, and it is not necessary to purchase additional equipment necessary for connecting the driving motor, reducer and pump, and additional equipment necessary for connecting the reducer and motor. The purpose is to provide a pump with a built-in reducer that can reduce the maximum.

It is characterized in that the structure.

도면중 미설명 부호 (60)은 카플링이다.Reference numeral 60 in the figure is a coupling.

이와같이 된 본 고안은 구동모터(20)가 장착되는 회전축(50)의 종단에 헬리컬(51)을 성형하고, 구동기어(11)와 메카니칼 씰(12) 및 구동 임펠러(13)가 장착된 회전축(10)에 헬리컬(51)과 맞물려 회전하는 감속기(30)를 장착하며, 상기 구동기어(11)와 맞물려 회전하는 종동기어(41)가 장착된 회전축(40)에 메카니칼 씰(12')과 종동 임펠러(42)를 장착하여 구성함으로써, 감속기(30)를 별도로 구입할 필요가 없으며, 구동모터(20)와 감속기(30) 및 펌프(가)를 조립하는데 소요되는 시간을 절약할 수 있게 된다.According to the present invention, the helical 51 is formed at the end of the rotating shaft 50 on which the driving motor 20 is mounted, and the rotating shaft on which the driving gear 11, the mechanical seal 12, and the driving impeller 13 are mounted ( 10) is equipped with a reduction gear 30 that rotates in engagement with the helical 51, the mechanical seal 12 'and the driven on the rotary shaft 40 is mounted with a driven gear 41 that rotates in engagement with the drive gear (11) By mounting the impeller 42, there is no need to purchase the reducer 30 separately, it is possible to save the time required to assemble the drive motor 20, the reducer 30 and the pump (a).

그리고 본 고안의 작동방법을 살펴보면, 펌프(가)와 구동모터(20)를 카플링(60)으로 연결 장착하고, 상기 구동모터(20)의 구동력으로 회전축(50)이 회전하게 되면, 회전축(50)의 헬리컬(51)과 맞물려 있는 감속기(30)의 회전축(10)이 동시 회전하게 되는데, 이때 헬리컬(51)과 감속기(30)의 익편 수가 다르게 성형되어 헬리컬(51)이 성형된 회전축(50)의 회전수가 감속기(30)를 통해 감소하게 되고, 감속된 상태에서 상기 회전축(10)에 장착되어 있는 구동기어(11)가 종동기어(41)와 맞물려 회전하면서 각 회전축(10)(40)의 종단에 장착된 구동 임펠러(13)와 종동 임펠러(42)가 맞물려 회전하면서 펌프(가)의 흡입구를 통해 슬러지가 많이 함유된 액체 등을 배출구로 배출하게 된다 .And look at the operation method of the present invention, the pump (a) and the drive motor 20 is connected to the coupling coupling 60, when the rotary shaft 50 is rotated by the driving force of the drive motor 20, the rotary shaft 50 The rotating shaft 10 of the reducer 30 meshed with the helical 51 of) rotates at the same time, wherein the number of blades of the helical 51 and the reducer 30 is formed differently so that the helical 51 is formed. The rotational speed of the motor is reduced through the reduction gear 30, and the driving gear 11 mounted on the rotating shaft 10 rotates while being engaged with the driven gear 41 while being decelerated. As the driving impeller 13 and the driven impeller 42 mounted at the end of the shaft rotate together with each other, the sludge-rich liquid and the like are discharged through the inlet of the pump.

이와같이 본 고안은 구동모터(20)와 펌프(가)의 회전축(50)을 직결시켜, 상기 회전축(50)에 성형되어 있는 헬리컬(51)과 감속기(30)를 맞물려 회전시킴으로써, 구동모터(20)와 펌프(가)를 연결하는 별도의 감속기(30)를 구입할 필요가 없어 부품구매에 따른 비용과 감속기(30) 설치에 따른 시간을 절감하고, 감속기(30)의 유지보수와 보관에 따른 번거러움을 해소할 수 있을 뿐만 아니라, 좁은 공간에서도 설치와 운반이 용이하여 펌프의 효율성을 극대화시킨데 그 효과가 있다.As such, the present invention directly connects the rotational shaft 50 of the driving motor 20 and the pump A, and rotates the helical 51 and the reduction gear 30 formed on the rotational shaft 50 to rotate, thereby driving the driving motor 20. There is no need to purchase a separate reducer (30) connecting the pump and (A) saves the cost of purchasing parts and the time according to the installation of the reducer (30), and the hassle of maintenance and storage of the reducer (30) In addition to solving the problem, it is easy to install and transport in a narrow space, thereby maximizing the efficiency of the pump.
