공기압축기의 와이퍼 링 박스{WIPER RING BOX OF AIR COMPRESSOR}Wiper ring box of air compressor {WIPER RING BOX OF AIR COMPRESSOR}

본 고안은 공기압축기의 와이퍼 링 박스에 관한 것으로, 특히 오일 누설을 최소화한 와이퍼 링 박스에 관련한다.The present invention relates to a wiper ring box of an air compressor, and more particularly to a wiper ring box that minimizes oil leakage.

와이퍼 링 박스(wiper ring box)는 공기압축기의 크랭크 샤프트의 단부에 결합하여 윤활 오일의 누설을 방지하고 크랭크 샤프트의 상하 왕복운동을 원활하게 하는 역할을 한다.Wiper ring box (wiper ring box) is coupled to the end of the crankshaft of the air compressor serves to prevent the leakage of lubricating oil and smooth the vertical reciprocating motion of the crankshaft.

도 1은 종래의 와이퍼 링 박스를 나타내는 단면도이다.1 is a cross-sectional view showing a conventional wiper ring box.

도 1을 참조하면, 와이퍼 링 박스의 몸체(10)는 상하 개구된 상태에서 상부 개구로부터 크랭크 샤프트(20)가 상하왕복 가능하게 삽입되고, 이 상태에서 상부 개구는 그랜드 커버(gland cover; 30)에 의해 밀폐된다.Referring to Figure 1, the body 10 of the wiper ring box is inserted into the crankshaft 20 up and down from the upper opening in the upper and lower opening state, in the upper opening is a gland cover (gland cover) 30 It is sealed by.

그랜드 커버(30)에 인접하여 내부에는 씰(40)이 설치되며, 씰(40)의 하부에는 크랭크 샤프트(20)의 단부를 지지하고 크랭크 샤프트(20)의 상하왕복에 의해 비산된 오일을 리턴하기 위한 공간(15)과 오일 저장공간(16)을 구획하여 정의하는 다 수의 와이퍼 링(12)이 설치된다.A seal 40 is installed inside the grand cover 30, and the lower portion of the seal 40 supports the end of the crank shaft 20 and returns oil scattered by the up and down of the crank shaft 20. A plurality of wiper rings 12 are defined to partition the space 15 and the oil reservoir 16.

이러한 와이퍼 링 박스에 의하면, 크랭크 샤프트(20)가 상하왕복 함에 따라, 와이퍼 링(12)과 크랭크 샤프트(20) 사이의 간극으로 통하여 오일이 유입되어 크랭크 샤프트(20)의 왕복운동을 원활하게 한다.According to such a wiper ring box, as the crank shaft 20 moves up and down, oil flows through the gap between the wiper ring 12 and the crank shaft 20 to smoothly reciprocate the crank shaft 20. .

그러나, 종래의 구성에 의하면, 도 2에 나타낸 바와 같이, 다수의 와이퍼 링(12)의 정렬이 일정하지 않기 때문에 와이퍼 링(12)과 크랭크 샤프트(20) 사이의 간극이 넓기 때문에 지나치게 많은 양의 오일이 유입되기 때문에 그랜드 커버(30)가 이를 충분히 막지 못하여 외부로 누설되는 문제점이 있다. However, according to the conventional configuration, as shown in Fig. 2, since the alignment of the plurality of wiper rings 12 is not constant, the gap between the wiper ring 12 and the crankshaft 20 is wide, so that a large amount of Since the oil is introduced, there is a problem that the grand cover 30 does not sufficiently block it and leaks to the outside.

통상, 윤활 오일은 공기압축기에서 마찰력 감소 및 마모 방지, 청정역할을 하는 필수적인 사항으로 외부 누설이 최소로 되어야 할 필요가 있다.In general, lubricating oils are essential for reducing friction, preventing abrasion and cleaning in air compressors, and need to minimize external leakage.

더욱이, 몸체(10)의 측면으로 형성된 배출구(14)를 통하여 화살표 b로 나타낸 것처럼 외부에 설치된 리턴 라인(미도시)을 통하여 오일이 저장공간(16)으로 순환되는데, 리턴 라인이 꺾일 수밖에 없어 오일의 드레인 저항이 증가하게 되며, 이에 따라 공간(15)에 충전된 오일이 그랜드 커버(30)에 가하는 압력이 증가하기 때문에 오일의 누설이 가중된다. Moreover, the oil is circulated to the storage space 16 through the return line (not shown) installed outside as shown by arrow b through the outlet 14 formed on the side of the body 10, the return line is bound to be broken, the oil The drain resistance of the oil is increased, and thus the leakage of oil is increased because the pressure applied to the grand cover 30 by the oil filled in the space 15 increases.

따라서, 본 고안의 목적은 오일의 누설을 최소화한 공기압축기의 와이퍼 링 박스를 제공하는 것이다.Accordingly, an object of the present invention is to provide a wiper ring box of an air compressor which minimizes leakage of oil.

상기의 목적은, 상하 개구된 상태에서 상부 개구로부터 내부로 크랭크 샤프트가 왕복운동 가능하게 삽입되는 몸체를 구비한 와이퍼 링 박스에 있어서, 상기 삽입된 크랭크 샤프트의 단부를 지지하는 캡이 상기 몸체와 결합 설치되어 비산된 오일을 수용하는 공간과 오일 저장공간을 구획하고, 상기 캡과 몸체의 연결부에는 상기 수용 공간과 상기 오일 저장공간과 연통하는 다수의 오일 배출구가 형성된 공기압축기의 와이퍼 링 박스에 의해 달성된다.The above object is a wiper ring box having a body in which a crankshaft is reciprocally inserted from an upper opening into an inwardly open state, wherein a cap for supporting an end of the inserted crankshaft is engaged with the body. It is provided by the wiper ring box of the air compressor, which is installed to partition the oil storage space and the oil storage space, and the connection portion of the cap and the body has a plurality of oil outlets communicating with the accommodation space and the oil storage space. do.

바람직하게, 상기 오일 배출구에 이어지는 상기 캡의 외측 가장자리는 일정한 하향 경사각을 갖는다.Preferably, the outer edge of the cap following the oil outlet has a constant downward inclination angle.

바람직하게, 상기 캡과 몸체는 일체로 제작될 수 있다.Preferably, the cap and the body can be manufactured integrally.

상기한 구성에 의하면, 그랜드 커버에 가해지는 압력을 줄여 오일의 누설을 최소화할 수 있다.According to the above configuration, it is possible to minimize the pressure applied to the grand cover to minimize the leakage of oil.

또한, 오일의 누설을 최소화함으로써 오일의 소모를 줄일 수 있다.In addition, it is possible to reduce the consumption of oil by minimizing the leakage of oil.

이하, 첨부된 도면을 참조하여 본 고안의 일 실시 예를 설명한다.Hereinafter, with reference to the accompanying drawings will be described an embodiment of the present invention.

도 3은 본 고안의 와이퍼 링 박스를 나타내는 단면도이고, 도 4는 저면으로부터 본 도 3의 사진 이미지이다.3 is a cross-sectional view showing a wiper ring box of the present invention, Figure 4 is a photographic image of Figure 3 seen from the bottom.

도 3을 참조하면, 와이퍼 링 박스의 몸체(100)는 상하 개구된 상태에서 상부 개구로부터 크랭크 샤프트(20)가 상하로 왕복운동 가능하게 삽입되고, 이 상태에서 상부 개구는 그랜드 커버(gland cover; 30)에 의해 밀폐되며, 그랜드 커버(30)에 인접하여 내부에는 씰(40)이 설치된다.Referring to FIG. 3, the body 100 of the wiper ring box is inserted into the crankshaft 20 so as to reciprocate upward and downward from the upper opening in a vertically open state, in which the upper opening may include a gland cover; Sealed by 30, the seal 40 is installed inside the grand cover 30 adjacent.

씰(40)의 하부에는 크랭크 샤프트(20)의 단부를 지지하는 캡(106)이 몸체(100)와 일체로 형성되며, 캡(106)과 몸체(100)의 연결부에는 다수의 오일 배출구(102, 104)가 형성된다. 이에 따라, 캡(106)과 몸체(100) 및 씰(40)로 둘러싸이는 공간(105)과 오일 저장공간(107)이 구획되어 형성된다.A cap 106 supporting the end of the crankshaft 20 is integrally formed with the body 100 at the lower portion of the seal 40, and a plurality of oil outlets 102 are provided at the connection portion between the cap 106 and the body 100. , 104). Accordingly, the space 105 and the oil storage space 107 surrounded by the cap 106, the body 100, and the seal 40 are partitioned and formed.

이러한 구성에 의하면, 도 4에 나타낸 것처럼, 캡(106)이 몸체(100)와 일체로 가공되기 때문에, 캡(106)과 크랭크 샤프트(20) 사이의 간극이 미세하여 오일의 비산이 많지 않으며, 결과적으로 공간(105)에 충전되는 오일의 양이 많지 않다.According to this structure, as shown in FIG. 4, since the cap 106 is integrally processed with the body 100, the gap between the cap 106 and the crankshaft 20 is minute and there is not much scattering of oil. As a result, the amount of oil filled in the space 105 is not large.

따라서, 그랜드 커버(30)에 가해지는 오일의 압력이 높지 않기 때문에, 그랜드 커버(30)를 통하여 누설되는 오일의 양도 많지 않다.Therefore, since the pressure of the oil applied to the grand cover 30 is not high, the amount of oil leaking through the grand cover 30 is not large.

또한, 몸체(100) 내부에 형성된 배출구(102, 104)를 통하여 오일이 순환되므로 드레인 저항이 작으며, 이에 따라 공간(105)을 채우기 전에 오일이 배출되어 그 랜드 커버(30)에 가해지는 압력이 작으며, 따라서 그랜드 커버(30)를 통하여 누설되는 오일의 양도 많지 않다.In addition, since oil is circulated through the outlets 102 and 104 formed inside the body 100, the drain resistance is small, so that the oil is discharged before filling the space 105 and applied to the land cover 30. This is small, and therefore the amount of oil leaking through the grand cover 30 is not large.

캡(106)은 몸체(100)와 일체로 제작될 수 있지만, 제조비용의 절감을 위하여 별도로 제작되어 용접 등에 의해 몸체(100)에 접합될 수 있다.The cap 106 may be manufactured integrally with the body 100, but may be manufactured separately and bonded to the body 100 by welding or the like to reduce manufacturing costs.

또한, 배출구(102, 104)와 이어지는 캡(106)의 외측 가장자리 부분은 적절한 하향 경사각을 주어 오일의 드레인 저항을 최소화할 수 있다.In addition, the outer edge portions of the outlets 102 and 104 and the subsequent cap 106 may be given an appropriate downward angle of inclination to minimize the drain resistance of the oil.

이상에서는 본 고안의 실시 예를 예로 들어 설명하였지만, 당업자의 수준에서 다양한 변경이 가능하다. 따라서, 본 고안은 상기의 실시 예에 한정되어 해석되어서는 안 되며, 이하에 기재된 등록청구범위에 의해 해석되어야 한다.In the above described an embodiment of the present invention as an example, various changes are possible at the level of those skilled in the art. Therefore, the present invention should not be construed as limited to the above embodiments, but should be interpreted by the claims set forth below.
