본 고안은 캔드 펌프에 관한 것으로, 특히 스테이터캔과 베어링홀더와 베어링의 결합구조에 의해 누수를 방지하도록 한 캔드 펌프의 누수 방지 구조에 관한 것이다.The present invention relates to a can pump, and more particularly to a leak prevention structure of the can pump to prevent leakage by the coupling structure of the stator can, the bearing holder and the bearing.

종래의 온수순환용 펌프의 누수방지구조는 제1도 내지 제4도에 도시된 바와같이, 회전축(16)의 반부하측단을 지지하는 베어링(6)이 삽입되는 베어링홀더(8)가 프레임(10)에 절반정도 인서트되고, 스테이터캔(9)의 반부하측(9a)의 대측단과 베어링홀더(8)의 외주면(8a)이 오링(7)에 의해 씰링되어 있다.As shown in FIGS. 1 to 4, a leak-proof structure of a conventional hot water circulation pump includes a bearing holder 8 into which a bearing 6 supporting a half load side end of the rotating shaft 16 is inserted into a frame ( It is inserted halfway into 10), and the opposite end of the half load side 9a of the stator can 9 and the outer peripheral surface 8a of the bearing holder 8 are sealed by the O-ring 7.

한편 제1도에 있어서, (1)은 케이싱, (2)는 임펠러, (3)은 앤드시일드, (4)는 스테이터어셈블리, (5)는 회전자어셈블리, (6)는 반부하측 베어링, (7)은 반부하측 오링, (14)는 부하측 오링(15)는 부하측베어링(16)은 회전축이다.1, (1) is a casing, (2) an impeller, (3) an end seal, (4) a stator assembly, (5) a rotor assembly, (6) a half load side bearing, (7) is a half load side O-ring, (14) a load side O-ring 15 is a load side bearing 16 is a rotating shaft.

상기와 같은 온수순환펌프에 전원을 인가하면 임펠러(2)가 회전하여 케이싱(1)의 흡입구(1a)로 물이들어온다.When power is applied to the hot water circulation pump as described above, the impeller 2 rotates and water enters the inlet 1a of the casing 1.

케이싱(1)내측에 들어온 물은 회전축(16)의 외주면과 부하측베어링(15)내주면 사이를 통해 스테이터캔(9)내부로 들어온다.Water entering the casing 1 enters into the stator can 9 through the outer circumferential surface of the rotating shaft 16 and the inner circumferential surface of the load side bearing 15.

스테이터캔(9)내부로 들어온 물은 회전축(16)의 외주면과 베어링(6, 15)의 내주면 사이에서 윤활작용을 한다.Water entering the stator can 9 is lubricated between the outer circumferential surface of the rotating shaft 16 and the inner circumferential surfaces of the bearings 6 and 15.

베어링홀더(8)와 스테이터캔(9)사이에 설치되는 오링(7), 및 앤드실드(3)와 스테이터캔(9)사이에 설치된 오링(14)은 스테이터캔(9)내측에서 금속충전부인 스테이터어셈블리(4)로 누수됨을 방지하는 역활을 한다.The O-ring (7) provided between the bearing holder (8) and the stator can (9), and the O-ring (14) provided between the end shield (3) and the stator can (9) are metal filling parts inside the stator can (9). It serves to prevent leakage to the stator assembly (4).

그런데 상기 오링(7)(14)는 고무로 구성되어 장기간 사용시 탄성을 잃어 기밀기능을 상실하여 스테이터어셈블리(4)측으로 누수될 우려가 있다. 특히 스테이터캔(9)의 반부하측과 접촉되는 베어링홀더(8)의 외주면은 일정조도이상이 되도록 가공되어야 오링(7)에 의해 씰링효과를 얻을 수 있다.However, the O-rings 7 and 14 are made of rubber, which loses elasticity when used for a long period of time, and loses airtight function, which may leak to the stator assembly 4 side. In particular, the outer circumferential surface of the bearing holder 8 in contact with the half load side of the stator can 9 must be machined to have a predetermined roughness or more to obtain a sealing effect by the O-ring 7.

그런데 베어링홀더(8)는 프레임(10)에 절반정도 인서트된 구조이므로 베어링홀더(8)의 외주면 및 내주면을 고속가공시 상시 인써트 결합이 분리되는 문제점이 있다.However, since the bearing holder 8 is inserted into the frame 10 about halfway, there is a problem that the insert coupling is always separated when the outer and inner circumferential surfaces of the bearing holder 8 are processed at high speed.

또한 종래의 베어링홀더(8)는 제3도에 도시된 바와같이, 구조가 복잡하여 생산성이 낮은 단점이 있다.In addition, the conventional bearing holder 8 has a disadvantage in that the productivity is low because the structure is complicated, as shown in FIG.

따라서, 본고안은 이러한 종래기술의 문제점을 해결하기 위한 것으로, 오일을 사용하지 않고 스테이터캔의 반부하측의 누수를 효과적으로 방지할수 있는 캔트펌프의 누수방지구조의 제공을 목적으로 한다. 또한 구조가 간단하여 생산성이 향상된 베어링홀더를 사용할수 있는 온수순환용 캔드펌프의 누수방지구조의 제공을 목적으로 한다.Accordingly, the present invention has been made to solve the problems of the prior art, and an object of the present invention is to provide a leak preventing structure of a cant pump which can effectively prevent leakage of the half load side of the stator can without using oil. In addition, the object of the present invention is to provide a leak-proof structure of a canned pump for hot water circulation, which can use a bearing holder with improved productivity due to its simple structure.

상기 목적은, 본고안에 따르면 회전축의 반부하측을 지지하는 한편 부하측을 기준으로 외경이 큰 대경부와 외경이 작은소경부가 순차로 형성된 반부하측 베어링과, 외주면 전체에 걸쳐 프레임에 인써트되는 한편 부하측을 기준으로 내경이 큰 대경부와 내경이 작은 소경부가 순차로 형성되고 상기 소경부에 상기 베어링의 소경부가 결합되는 베어링홀더와, 반부하측의 지름이 나머지부와 작은 한편 상기 지름이 작은 반부하측이 상기 베어링의 대경부의 외주면과 프레임의 내주면 사이에 위치된 스테이터캔과, 베어링홀더의 대경부와 베어링의 소경부와 스테이터캔의 반부하측단 사이에 채워진 충진물과를 구비하여 스테이터캔의 반부하측의 누수를 방지하게 되는 온수순환용 펌프의 누수방지구조를 제공함으로서 달성된다.The object is to support the half-load side of the rotating shaft according to the present proposal, while the large-diameter large diameter part and the small-diameter small diameter part are sequentially formed on the load side, and the bearing is inserted into the frame over the entire outer circumferential surface while the load side is referenced. The large diameter portion having a large inner diameter and the small diameter portion having a small inner diameter are sequentially formed, and a bearing holder having a small diameter portion of the bearing coupled to the small diameter portion, the diameter of the half load side is smaller than the rest, and the half load side with the small diameter is the bearing. The stator can is located between the outer circumferential surface of the large diameter part and the inner circumferential surface of the frame, and the filling part is filled between the large diameter part of the bearing holder and the small diameter part of the bearing and the half load side end of the stator can to prevent leakage of the half load side of the stator can. It is achieved by providing a leak-proof structure of the pump for hot water circulation.

베어링(6)의 소경부(6b)의 외주면은 베어링홀더(8)의 소경부(6b)의 내주면과 접촉된다.The outer circumferential surface of the small diameter portion 6b of the bearing 6 is in contact with the inner circumferential surface of the small diameter portion 6b of the bearing holder 8.

제6도에 도시된 바와같이 스테이터캔(9)는 소경의 반부하측(9b)가 부하측의 대경부(9a)와 단차로 형성된 구조이다.As shown in FIG. 6, the stator can 9 has a structure in which the half-load side 9b of the small diameter is formed stepwise with the large-diameter portion 9a on the load side.

제9도에 도시된 바와같이, 스테이터캔(9)의 반부하측(9b)는 베어링(6)의 대경부(6a)의 외주면가 프레임(10)의 부하측내주면(10b)사이에 끼워진 구조이다.As shown in FIG. 9, the half load side 9b of the stator can 9 has a structure in which the outer circumferential surface of the large diameter portion 6a of the bearing 6 is sandwiched between the load side inner circumferential surface 10b of the frame 10.

베어링홀더(8)의 대경부(8a)의 내주면과 반부하측 베어링(6)의 소경부(6b)의 외주면과 스테이터캔(9)의 반부하측(9b)의 단부는 공간(11)를 형성하며 서로 연접하게 된다.The inner circumferential surface of the large diameter portion 8a of the bearing holder 8 and the outer circumferential surface of the small diameter portion 6b of the half load side bearing 6 and the end portion of the half load side 9b of the stator can 9 form a space 11. They connect with each other.

상기 공간(11)에는 젤리상의 접착성을 갖는 충진물 예를들면 실리콘등이 채워져 스테이터캔(9)의 반부하측의 누수를 방지하게 된다.The space 11 is filled with a jelly-like adhesive, for example, silicon, to prevent leakage of the half load side of the stator can 9.

프레임(10)의 다이캐스팅시 베어링홀더(8)의 외주면(8c)은 프레임(10)의 베어링홀더결합부(10a)에 완전히 인서팅되고, 스테이터캔(9)의 반부하측(9b)가 베어링홀더(8)의 대경부(8a)의 내주면에 접촉되도록 스테이터캔(9)이 설치된다.The outer peripheral surface 8c of the bearing holder 8 is completely inserted into the bearing holder engaging portion 10a of the frame 10 during die casting of the frame 10, and the half load side 9b of the stator can 9 is a bearing holder. The stator can 9 is provided so that the inner peripheral surface of the large diameter part 8a of (8) may contact.

소정의 충전물이 소경부(6b)의 외주면에 도포된 반부하측베어링(6)이 스테이터캔(9)의 반부하측(9b)의 내주면을 따라 압입되어 베어링(6)의 소경부(6b)의 외주면이 베어링홀더(8)의 소경부(8b)에 접촉되도록 설치된다.The half-load side bearing 6, in which a predetermined filling is applied to the outer circumferential surface of the small-diameter portion 6b, is press-fitted along the inner circumferential surface of the half-load side 9b of the stator can 9, and the outer circumferential surface of the small-diameter portion 6b of the bearing 6 is pressed.

Filled by the pressure generated when the bearing 6 is pressed between the surfaces to be joined to serve as a sealing role of the half-load side of the stator can (9) to prevent leakage of the half-load side of the stator can (9).

이상에서 설명한 바와같이, 본 고안에 따르면, 오링을 사용하지 않고 스테이터캔의 반부하측의 누수를 방지할수 있고 종래 스테이터캔과 베어링홀더의 긴밀한 접촉을 위해서 베어링홀더의 외주면가공이 필요하였으나 충진물에 의한 씰리에 의해 상기 가공을 요하지 않게 된다. 또한 본 고안의 누수방지구조에 의해 베어링홀더의 구조가 단순화되어 베어링홀더의 생산성을 향상시킬수 있다.As described above, according to the present invention, it is possible to prevent the leakage of the half-load side of the stator can without using the O-ring, and the outer peripheral surface processing of the bearing holder is required for close contact between the stator can and the bearing holder.
