본고안운 축을 고정형으로 하는 온수순환펌프의 고정축을 고정시켜 주도록 하는 구조에 관한 것이다.The present invention relates to a structure for fixing a fixed shaft of a hot water circulation pump having a fixed shaft.
이를 좀더 상세히 설명하면 온수순환펌프는 회전자가 축착된 회전축을 회전시키도록 하는 회전축형과 회전자는 구동마그네트와 함께 회전하고 축이 고정되는 고정축형으로 크게 분리된다.To explain this in more detail, the hot water circulation pump is divided into a rotating shaft type for rotating the rotating shaft in which the rotor is condensed and a fixed shaft type in which the rotor rotates with the driving magnet and the shaft is fixed.
본고안은 고정축형의 온수순환펌프에 있어서 그 고정축을 보다 견고하게 고정시켜주도록 함을 그 목적으로 하고 있다.This paper aims to fix the fixed shaft more firmly in the fixed shaft type hot water circulation pump.
본고안의 주지적인 특징은 회전자를 내장한 회전자하우징과 구동마그네트를 갖는 구동마그네트하우징을 일체형의 회전체로 형성하여 고정축에 축착할 때 그 회전체의 상하 양단에 베어링을 장착하여 축착하되 그 상하 베어링을 그들의 외측에서 각각 압착하도록 된 것이다.The main feature of this paper is that the rotor housing with the rotor and the drive magnet housing with the driving magnet are formed as an integral rotor, and when bearing is fixed to the fixed shaft, the bearing is mounted on both upper and lower ends of the rotor to be fixed. The upper and lower bearings are to be crimped on the outside of each.
이하 첨부도면에 의거 상세히 설명한다.Hereinafter will be described in detail based on the accompanying drawings.
제2도는 종래의 회전축형의 온수순환펌프(1-1)에 있어서 회전축(21)을 장착한 상태의 예시단면도이다.2 is an exemplary cross-sectional view of a state in which the rotating shaft 21 is mounted in the conventional rotating shaft type hot water circulation pump 1-1.
모터하우징(10)의 내부에 고정자(11)가 환상형으로 고정되어 있고 그 내부에 회전자(12)가 회전축(21)에 축착되어 있는데, 그 회전축(21)은 모터하우징(1)의 상하에 베어링(17)을 개입시켜 고정되고 베어링(17)은 이탈되지 못하도록 클립(22)으로 고정되어 있다.The stator 11 is fixed to the inside of the motor housing 10 in an annular shape and the rotor 12 is fixed to the rotating shaft 21 therein, the rotating shaft 21 of the upper and lower sides of the motor housing 1 It is fixed through the bearing 17 and the bearing 17 is fixed with a clip 22 so as not to be separated.
그 회전축(21)의 상측에는 구동마그네트(16)가 매입된 구동마그네트하우징(15)이 장착되어 있고, 간격판(5)으로 분할되는 펌프하우징(2)에는 하측에 종동마그네트(4)가 매입된 임펠러(3)가 축착되어 있다.The drive magnet housing 15 in which the drive magnet 16 is embedded is mounted on the upper side of the rotating shaft 21, and the driven magnet 4 is embedded in the pump housing 2 divided into the spacer plates 5. The impeller 3 which was used is condensed.
이와 같이된 회전축(21)형의 순환펌프(1-1)는 순환펌프(1)를 작동시킬 때 회전축(21)이 상하로 요동한다는 것이다.The circulation pump 1-1 of the rotary shaft 21 type as described above is that the rotary shaft 21 oscillates up and down when the circulation pump 1 is operated.
이와 같은 회전축(21)의 상하요동을 제한다는 것이 클립(22)이며 이 클립(22) 역시 순환펌프(1)를 장기간 사용하게 되면 풀림현상이 발생하여 요동을 방지할 수 없다는데 문제가 있다.It is the clip 22 to remove the up and down rocking of the rotation shaft 21, and this clip 22 also has a problem that the loosening occurs when the circulation pump 1 is used for a long time to prevent the rocking.
본고안은 특히 고정축형 온수순환펌프(1)에서 회전체(13)를 더욱 견고히 고정시켜 요동을 방지할 수 있도록 함을 목적으로 한다.In particular, the subject of the present invention is to fix the rotating body 13 more firmly in the fixed shaft type hot water circulation pump 1 so as to prevent shaking.
제1도는 본고안에 따른 고정축형 순환펌프(1)의 구조를 보인 예시도이다.1 is an exemplary view showing a structure of a fixed shaft circulation pump 1 according to the present invention.
모터하우징(10)의 구동마그네트(16)와 펌프하우징(2)의 종동마그네트(4)가 간격판(5)에 의해 이격된 상태에서 상호간의 자력에 의해 연동되면서 임펠러(3)를 회전시켜 유체를 순환시키도록 된 순환펌프(1)에 있어서, 회전자(12)를 장착한 회전자하우징(14)과 구동마그네트(16)를 갖는 구동마그네트하우징(15)이 일체로 형성된 회전체(13)를 고정축(20)에서 회전자재하도록 베어링(17)으로 축설하고 그 고정축(20)의 상하축을 축지지봉(6)과 지지돌부(18)의 요홈에 삽착하되 베어링(17)을 간격판(5)에 연설된 축지지봉(6)의 압압변(7)과 지지돌부(18)의 지지면(18-1)이 각 상하에서 압착하도록 된 것을 특징으로 하고 있다.The driving magnet 16 of the motor housing 10 and the driven magnet 4 of the pump housing 2 interlock with each other by magnetic force while being spaced apart by the spacer plate 5 to rotate the impeller 3 to rotate the fluid. In the circulation pump (1) to circulate the rotor 13, the rotor body (14) equipped with the rotor (12) and the drive magnet housing (15) having the drive magnet (16) integrally formed with the rotor (13). To the bearing 17 so as to rotate on the fixed shaft 20, and insert the upper and lower shafts of the fixed shaft 20 into the grooves of the shaft support rod 6 and the support protrusion 18, and the bearing 17 to the spacer plate ( It is characterized in that the pressing edge 7 of the shaft supporting rod 6 and the supporting surface 18-1 of the supporting protrusion 18 are squeezed from each other up and down.
이와같이 구성된 본고안은 고정축(20)에 베어링(17)으로 축착된 회전체(13)가 회전하게 된 순환펌프(1)에 있어서, 고정축(20)을 축지지봉(6)과 지지돌부(18)에 의해 고정시키게 되고 회전체(13)가 고정축(20)에서 회전할 때 승하강하는 것을 방지할 수 있도록 상하단의 베어링(17)을 고정시켜 주는 것으로서, 특히 상측의 베어링을 간격판(5)에서 연설되는 축지지봉(6)의 선단에 돌설된 압압변(7)으로 내측 금구를 하측방향으로 압압하여 주고, 하측의 베어링은 고정축(20)을 지지하는 지지돌부(18)의 최상단의 지지면(18-1)이 내측 금구를 상축방향으로 압압하여 주도록 되어 있다.In this configuration configured in this way in the circulation pump (1) in which the rotating body 13 is fixed to the fixed shaft 20 by the bearing 17, the fixed shaft 20, the shaft support rod 6 and the support protrusion ( 18) to fix the upper and lower bearings 17 so as to prevent the upper and lower ends of the rotor 13 from rotating when the rotor 13 rotates on the fixed shaft 20. Press the inner bracket downward in the pressing direction (7) protruding from the tip of the shaft support rod (6) to be released in 5), the lower bearing is the top end of the support protrusion (18) for supporting the fixed shaft (20) The support surface 18-1 presses the inner bracket in the upward axis direction.
고정축(20)의 상하측이 축지지봉(6)과 지지돌부(18)에 의해 고정되어 있으므로 가동중에 축이 요동하거나 상하로 움직일 염려가 없어 회전자하우징(14)이 원활하게 회전할 수 있도록하여 줌은 물론 베어링(17)사이에 축착된 회전체(13)는 회전을 할 때 상, 하요동이 완전히 배제된 상태에서 회전을 하게 되므로 순환펌프(1)의 성능을 향상시키게 된다.Since the upper and lower sides of the fixed shaft 20 are fixed by the shaft support rods 6 and the support protrusions 18, there is no fear that the shaft may swing or move up and down during operation so that the rotor housing 14 can rotate smoothly. Of course, the rotating body 13, which is condensed between the bearings 17, as well as the zoom, is rotated in a state where the upper and lower swings are completely excluded when rotating, thereby improving the performance of the circulation pump 1.
특히 장기간동안 순환펌프(1)를 가동시키더라도 상용하더라도 축지지봉(6)의 압압변(7)과 지지돌부(18)가 마모될 하등의 이유가 없어서 고정축(2)과 회전체(13)가 요동할 염려는 완전히 배제시킬 수 있다.In particular, even if the circulating pump 1 is operated for a long time, the fixed shaft 2 and the rotating body 13 have no reason to wear down the pressure side 7 and the support protrusion 18 of the shaft support rod 6 even if they are commercially available. Concerns about fluctuations can be completely ruled out.
또한 이들 베어링들을 고정시킬 때 특별한 구조로된 기구를 사용하지 않고 고정시킬 수 있기 때문에 제조원가를 상승시킬 염려가 없고 또 조립도 간단히 실시할 수 있다는 것이다.In addition, since these bearings can be fixed without using a specially designed mechanism, there is no fear of increasing manufacturing costs and the assembly can be performed easily.
이와 같이 본고안에 따르면 회전체(13)를 축착하고 있는 베어링(17)을 축지지봉(6)의 압압변(7)과 지지돌부(18)가 상하에서 압착하기 때문에 회전하는 회전체(13)가 요동할 염려가 전혀 없고 특히 별도의 장치 없이도 간격판(5)과 모터하우징(10)의 하단부에 각각 연설된 축지지봉(6)가 지지돌부(18)에 의해 고정축(20)과 베어링(17)을 억류토록 함으로써 별도의 제조원가가 요구되지 않으면서도 조립을 간단히 설시할 수 있도록 된 유용한 것이다.Thus, according to the present proposal, the bearing 17 holding the rotor 13 in contact with the pressing member 7 and the support protrusion 18 of the shaft support rod 6 is pressed up and down, so that the rotating member 13 which rotates is There is no fear of swinging, and in particular, the shaft support rods 6, which are projected to the lower ends of the spacer 5 and the motor housing 10, respectively, without a separate device, are supported by the fixed shaft 20 and the bearing 17 by the support protrusions 18. By detaining), it is useful to easily install assembly without requiring separate manufacturing cost.
