[산업상의 이용분야][Industrial use]

본 발명은 자동차의 수냉식 엔진에 사용되는 냉각수 순환용 펌프에 대한 것으로 더 자세히 말하자면 냉각수가 펌프 본체의 내부까지 순환할 수 있도록 하여 고속으로 가동되는 축부의 윤활유(Grease 油)가 열화되는 것을 방지하고, 펌프 본체의 강성을 증대시켜 전체적인 수명을 연장시키기 위한 것이다.The present invention relates to a pump for cooling water circulation used in a water-cooled engine of an automobile. More specifically, the cooling water can be circulated to the inside of a pump main body to prevent deterioration of lubricant oil of a shaft operated at high speed. To increase the rigidity of the pump body to extend the overall life.

[종래의 기술][Prior art]

종래의 일반적인 냉각수 펌프를 보면 제3도 및 제4도 도면에서 보는 바와 같이 구성되어 있다.The conventional general cooling water pump is constructed as shown in FIGS. 3 and 4.

즉, 펌프 본체(a)의 일측으로는 확장된 펌프실(b)이 형성되어 있고, 그 후방으로는 베어링 삽입부(c)가 형성되어 있는 바, 이 베어링 삽입부(c)에 베어링(d)과 같이 삽착된 베어링측(e)이 있고, 상기한 펌프실(b)에는 내부에서 회전할 일펠러(f)가 상기의 베어링축(e)단에 축착되어 있다.That is, an extended pump chamber b is formed at one side of the pump main body a, and a bearing insert c is formed at the rear of the pump main body a. There is a bearing side e inserted as described above. In the pump chamber b, a one-feller f to rotate therein is fixed to the bearing shaft e end.

이때 임펠러(f)의 후방에는 실링부(g)가 있으며, 그 뒤로 공간부(h)가 있고, 이 공간부(h)는 상, 하축의 증기배출구(j)(k)로써 개통되어 레어링부를 냉각시킬 수 있도록 되어 있다.At this time, the rear of the impeller (f) has a sealing portion (g), behind the space portion (h), the space portion (h) is opened and opened by the upper and lower steam outlet (j) (k) The part can be cooled.

[종래기술의 문제점][Problems with Prior Art]

그러나 상기와 같은 종래의 펌프에 있어서는 단순히 공간부(h)를 형성해 놓은 구조의 냉각수단만으로 베어링부를 충분히 냉각시켜 줄 수 없기 때문에 베어링의 마찰열에 요인하여 베어링(d) 및 축부에 공급한 윤활유가 열화되고, 윤활유가 열화되면 결과적으로 펌프의 수명을 단축하게 되는 문제가 있다.However, in the conventional pump as described above, the bearing part cannot be sufficiently cooled by only the cooling means having the space h formed therein, so that the lubricant oil supplied to the bearing d and the shaft part deteriorates due to the frictional heat of the bearing. If the lubricant is deteriorated, there is a problem that shorten the life of the pump.

[발명이 해결하고자 하는 과제][Problem to Solve Invention]

따라서 본 발명은 상기와 같은 제반 문제점을 감안해 이를 시정 보완하고자 안출한 것으로서 발명의 주된 목적은 펌프 본체의 구조를 내부에 수실을 갖는 이중 구조로 형성하므로서 냉각수가 본체의 내부까지 흐르도록 유도하여 냉각기능을 배가 시키고, 또 그 이중구조로 인해 펌프본체의 강성이 증대될 수 있도록 하는데 있다.Therefore, the present invention has been made in view of the above problems to correct the problem, the main object of the invention is to form a dual structure having a water chamber in the structure of the pump body to guide the coolant flows to the interior of the body cooling function It is to double the and to increase the rigidity of the pump body due to the dual structure.

[과제를 해결하기 위한 수단][Means for solving the problem]

그리고 이를 위한 특징적인 구성은 본체의 후방에 마련된 베어링압입부에 축을 가진 베어링을 축착하고, 이 베어링축의 선단부에 임펠러를 축설하되, 펌프본체로 부터 확장된 펌프실의 속에서 회전할 수 있도록 하면서, 상기한 베어링과 임펠러의 사이에 실링부를 두고, 그 후방에 공간부를 형성한 냉각수 순환용 펌프에 있어서, 상기한 베어링 압입부의 바깥쪽으로 본체외통을 다시 형성하여 이 본체외통과 상기한 베어링 압입부의 사이가 펌프실과 연통된 내부 수실이 되게 구성하므로서 펌프실의 냉각수가 임펠러의 회전력으로 인해 유입 순환되어 베어링부가 충분히 냉각될 수 있도록 하는데 있다.And a characteristic configuration for this is a bearing bearing with a shaft on the bearing indentation provided in the rear of the main body, and the impeller is arranged on the tip of the bearing shaft, while allowing the rotation in the pump chamber extended from the pump body, In a cooling water circulation pump having a sealing portion between a bearing and an impeller, and having a space portion behind the bearing, the main body outer cylinder is formed again to the outside of the bearing press-in part, and the main body and the bearing press-in part are separated from each other. It is configured to be an internal water chamber in communication with the cooling water in the pump chamber due to the rotational force of the impeller to allow the bearing portion to be sufficiently cooled.

[실시예]EXAMPLE

이하 본 발명의 상세한 구성 및 작용효과를 첨부한 도면에 따라 설명하면 다음과 같다.Hereinafter, the detailed configuration and effect of the present invention will be described with reference to the accompanying drawings.

제1도는 본 발명의 구성을 보인 단면도이고, 제2도는 제1도의 A-A선 단면도이다.1 is a cross-sectional view showing the configuration of the present invention, Figure 2 is a cross-sectional view taken along the line A-A of FIG.

도면에서 보듯이 본 발명의 펌프는 펌프본체(1)가 이중으로 형성되어 내부에 내부수실(2)을 갖는 것이 특징이다.As shown in the figure, the pump of the present invention is characterized in that the pump main body 1 is formed in a double and has an internal water chamber 2 therein.

먼저 펌프의 전체 구성을 살펴보면 펌프본체(1)의 후방에 베어링 압입부(11)가 형성되어 있는 바, 이 베어링 압입부(11)에는 베어링축(12)을 포함하는 베어링(3)이 압착되어 있고, 이 베어링축(12)의 선단에는 임펠러(4)가 축설되어 있으며, 이 임펠러(4)와 베어링(3)의 사이에는 베어링 압입부(11)가 연장된 상태에서 실링부(13)가 끼워진다.First of all, the overall configuration of the pump has a bearing indentation part 11 formed at the rear of the pump body 1, and the bearing indentation part 11 includes a bearing 3 including a bearing shaft 12 therein. The impeller 4 is arranged at the tip of the bearing shaft 12, and the sealing portion 13 is formed between the impeller 4 and the bearing 3 in a state where the bearing press-fit portion 11 is extended. Is fitted.

또 상기한 실링부(13)와 베어링(3)의 사이에는 공간부(14)가 확보되어 있고, 이 공간부(14)에는 상, 하로 증기배출구(15a)(15b)가 형성되어 있으며, 상기한 베어링축(12)의 후단에는 동력을 전달받기 위한 풀리브라켓(16)이 축착되어 있다.In addition, a space portion 14 is secured between the sealing portion 13 and the bearing 3, and the space portion 14 is provided with steam outlets 15a and 15b up and down. At the rear end of one bearing shaft 12, a pulley bracket 16 for receiving power is fixed.

여기서 본 발명의 요부는 상기한 베어링 압입부(11)의 외주연 바깥쪽으로 별도의 본체외통(17)을 형성하여 상기한 베어링 압입부(11)와 이 본체외통(17)의 사이가 내부수실(2)이 되게 하고, 또 이는 앞에서 말한 펌프실(5)과 통해 있도록 하여 냉각수가 이 내부수실(2)까지 진입할 수 있도록 한다는 것이다.The main part of the present invention forms a separate body outer cylinder 17 on the outer circumferential outer side of the bearing indentation portion 11 so that the space between the bearing indentation portion 11 and the body outer cylinder 17 is an inner chamber ( 2), which means that the coolant can enter the internal water chamber 2 through the pump chamber 5 described above.

따라서 펌프본체(1)는 상기한 베어링 압입부(11)와 그 바깥쪽으로 또 형성된 본체외통(17)이 이중으로 형성되어 있는 것이며, 상기의 내부수실(2)에는 임펠러(4)가 회전하므로 인해 계속 냉각수가 유입되도록, 또 순환될 수 있도록 된 것이다.Therefore, the pump body 1 is formed of the bearing press-fitting part 11 and the main body outer cylinder 17 formed further outward, and the impeller 4 is rotated in the inner water chamber 2 due to the rotation. The cooling water can continue to be introduced and circulated.

참고로, 상기한 내부수실(2)은 제2도 도면에서 보듯이 상,하 증기배출구(15a)(15b)와 연통되지 않도록 별개로 차단되어 있을 뿐만 아니다 상측의 증기배출구(15a)는 수직으로 형성되지 않고 일측으로 기울어 지게 형성되어 있다.For reference, the internal chamber 2 is not only separately blocked so as to communicate with the upper and lower steam outlets 15a and 15b, as shown in FIG. 2, and the upper steam outlet 15a is vertically disposed. It is not formed and is formed to be inclined to one side.

다음은 상기와 같이 구성된 본 발명의 작동 상태를 설명한다.The following describes the operating state of the present invention configured as described above.

본 발명의 펌프를 냉각수의 순환과정에 부착하여 사용했을 때, 엔진의 크랭크축과 연결된 풀리브라켓트(16)를 통해 동력이 전달되면 펌프실(5)의 임펠러(4)가 회전을 하게 하고, 이때의 임펠러 회전력은 냉각수를 엔진으로 부터 라디에이터 쪽으로 계속 이동시키게 되어 엔진의 원활한 냉각작용이 이루어지는 것이고, 본 발명의 펌프에서는 임펠러(4)의 힘으로 인해 와류를 일으킨 냉각수의 일부가 상기한 내부수실(2)로 순환되게 한다.When the pump of the present invention is attached to the cooling water circulation process, when the power is transmitted through the pulley bracket 16 connected to the crankshaft of the engine, the impeller 4 of the pump chamber 5 rotates, Impeller rotational force is to continue to move the coolant from the engine to the radiator to achieve a smooth cooling action of the engine, in the pump of the present invention is a part of the coolant that caused the vortex due to the force of the impeller (4) the inner chamber 2 To circulate.

그러므로 냉각수는 고속회전으로 인해 발생하는 베어링(3)의 마찰열을 충분히 냉각시켜 줄 수 있게 되는 것이고, 따라서 윤활유가 열화 되지 않으므로 윤활유 및 베어링의 수명이 오래 가는 것이다.Therefore, the cooling water is to sufficiently cool the frictional heat of the bearing (3) generated by the high-speed rotation, so that the lubricant does not deteriorate the life of the lubricant and the bearing is long.

뿐만 아니라 상기한 본체외통(17)의 구조는 기존의 펌프와 달리 베어링 압입부(11)와 이중의 본체 구조를 가지는 셈이어서 그 펌프본체(1)의 강성이 한층 배가 되는 것이다.In addition, unlike the conventional pump, the structure of the main body outer cylinder 17 has a bearing main body 11 and a dual main body structure, so that the rigidity of the pump body 1 is further doubled.

그리고, 상기한 상,하 증기배출구(15a)(15b)중에서 상측의 증기배출구(15a)가 수직으로 형성되지 않고 어느 한쪽으로 약간 기울어져 있기 때문에 공간부(14)로 누출한 후, 회전열에 의해서 분리된 냉각수의 증기가 쉽게 빠지도록 함은 물론, 운전중 외기에 노출된 부분이기 때문에 이물질이 침입되지 않도록 하는 효과가 있는 바, 이는 베어링의 이상 마모를 예방하여 펌프의 수명이 오래가도록 하는 것이다.Since the upper and lower steam outlets 15a and 15b are not vertically formed and are slightly inclined to either side, the upper and lower steam outlets 15a and 15b leak into the space 14, and then, by the heat of rotation. The vapor of the separated coolant is easily released, and because it is exposed to the outside air during operation, there is an effect of preventing foreign matter from invading, which prevents abnormal wear of the bearings, thereby prolonging the life of the pump.

[작용효과][Effect]

위에서 자세히 설명한 바와 같은 본 발명은 결과적으로 베어링 압입부(11)의 외측으로 냉각수가 유입 순환하는 내부수실(2)과 강성을 증대시키는 본체외통(17)이 추가로 형성된 것이기 때문에 종래의 일반적인 펌프와 달리 냉각수가 펌프 본체의 내부까지 순환하여 고속으로 가동되는 축부의 윤활유(Grease 油)가 열화되는 것을 방지하고, 펌프 본체의 강성을 증대 시켰기 때문에 펌프의 수명이 길어짐은 물론 상품성을 더 한층 향상시키게 되는 것이다.The present invention as described in detail above, as a result of the additional internal water chamber 2 through which the coolant is introduced and circulated to the outside of the bearing indentation portion 11 and the main body outer cylinder 17 to increase the rigidity, and thus the conventional general pump and Otherwise, the coolant circulates to the inside of the pump main body to prevent deterioration of lubricant oil in the shaft that is operated at high speed, and the rigidity of the pump main body is increased, thereby increasing the service life of the pump and further improving the merchandise. will be.
