본 고안은 로타리 콤프레서 구조에 관한 것으로, 특히 롤링피스톤을 삭제함에 따라 편심축의 가공과 조립성을 향상시켜 주도록 한 것이다.The present invention relates to a rotary compressor structure, in particular to improve the machining and assembly of the eccentric shaft by eliminating the rolling piston.
일반적으로 로타리 콤프레서는 로울러가 편심축의 회전에 따라 실린더내를 접속 구동하면서 회전하는 로울러와 접촉하는 베인을 통해 분리되는 압축실의 용적변화에 따라서 흡입구를 통해 흡입되는 냉매가스를 압축하여 토출구로서 배출하는 과정을 반복 실시하는 기기이다.In general, the rotary compressor compresses the refrigerant gas sucked through the suction port and discharges it as the discharge port according to the volume change of the compression chamber separated through the vane contacting the rotating roller while the roller is connected to the cylinder according to the rotation of the eccentric shaft. It is a device that repeats the process.
종래에는 이와같은 작동을 실시하는 로타리 콤프레서 구조가 첨부도면 제4도 및 제5도에 도시한 바와같은 구조로서, 제4도와 같은 구조의 콤프레서는 베인(3)과 이와 접촉 회전 구동하는 로울러간의 마찰을 줄여주기 위하여 롤링피스톤(1)을 사용한 것을 나타낸 것이고, 제5도의 콤프레서의 제4도의 콤프레서에 있어서 베인(3)과 롤링피스톤(1)간의 마찰을 더욱 극소화해 주기 위하여 베인(3)의 끝단부에 스틱롤러(10)를 장착하여 준 것이다.Conventionally, a rotary compressor structure that performs such an operation has a structure as shown in FIGS. 4 and 5 of the accompanying drawings, and a compressor having a structure as shown in FIG. 4 has a friction between the vane 3 and the roller driving contact rotation with it. It is shown that the rolling piston 1 is used to reduce the pressure, and the tip of the vane 3 is further minimized in order to further minimize the friction between the vane 3 and the rolling piston 1 in the compressor of FIG. The stick roller 10 is attached to the part.
그러나 종래 구조와 같이 롤링피스톤과 베인의 끝단부에 스틱롤러를 장착하여 베인과 롤링피스톤간의 마찰을 줄여주도록 하고 있으나, 이것은 편심축이 회전함에 따라 롤링피스톤이 편심축과 습동하여 압축실의 용적을 줄여 압축이 이루어지도록 하기 때문에 롤링피스톤과 편심축을 각각 따로 가공해 주어야만 하였고, 높은 정밀가공도로서 그 조립상태를 유지해 주어야 하므로 롤링피스톤과 편심축의 정밀가공과 외경이 큰 롤링피스톤의 내마모성 향상을 위한 재료비등의 원인에 따른 제작비가 상승하고, 또한 롤링피스톤과 편심축의 조립이 복잡하여 작업성 저하 및 공차 누적등이 문제점으로 대두하였다.However, as in the conventional structure, the stick roller is attached to the end of the rolling piston and the vane to reduce the friction between the vane and the rolling piston, but as the eccentric shaft rotates, the rolling piston slides with the eccentric shaft to reduce the volume of the compression chamber. The rolling piston and the eccentric shaft had to be processed separately because they were compressed so that they could be compressed, and the assembly of the rolling piston and the eccentric shaft had to be maintained with high precision. Due to the increase in manufacturing cost due to the cause, and assembling of the rolling piston and the eccentric shaft is complicated, workability and tolerance accumulation have emerged as problems.
본 고안은 이와같은 종래의 문제점을 개선해 주기 위하여 안출한 것으로서, 이를 첨부도면에 의하여 더욱 상세히 설명하면 다음과 같다.The present invention has been made in order to improve such a conventional problem, described in more detail by the accompanying drawings as follows.
롤링피스톤(1)이 실린더(2)내를 접속 구동하고, 롤링피스톤(1)과 접촉하는 베인(3)을 통해 압축실을 용적 변화시킴에 따라 냉매가스를 압축하도록 된 로타리 콤프레서에 있어서, 롤링피스톤(1)과 편심축(4)을 일체로 하는 로울러(5)를 형성하고, 로울러(5)와 접촉하는 스틱롤러(6)를 갖는 베인(3)에는 급유공(7)을 형성하여서 된 것이다.In a rotary compressor in which a rolling piston 1 connects and drives the inside of a cylinder 2 and compresses refrigerant gas as the volume of the compression chamber changes through a vane 3 in contact with the rolling piston 1. The roller (5) integrally forms the piston (1) and the eccentric shaft (4), and the oil supply hole (7) is formed in the vane (3) having the stick roller (6) in contact with the roller (5). will be.
이와같이 된 본 고안은 먼저 롤링피스톤(1)과 편심축(4)을 제3도에 도시된 바와같이 일체로 형성된 로울러(5)를 사용하도록 함에 따라 종래와 같은 편심축에 롤링피스톤을 끼운 형태와 같이 두개의 부품을 각각 사용하지 않고 두개의 부품을 하나로서 복합 형성하여 로울러(5)의 외주면이 직접 베인(3) 하방에 끼워져 있는 스틱롤러(6)와 접촉하면서 압축작용을 실시하도록 하여 두개부품의 가공오차를 해소하고 정밀도를 유지하도록 한 것이다.The present invention, as described above, uses the roller 5 formed integrally with the rolling piston 1 and the eccentric shaft 4 as shown in FIG. Similarly, two parts are combined without forming two parts, so that the outer circumferential surface of the roller (5) comes into contact with the stick roller (6) inserted directly under the vane (3) to perform a compression action. This eliminates processing errors and maintains precision.
또한, 본 고안에 따라서 롤링피스톤이 편심축과 일체로 형성되어 하나의 로울러(5)를 형성한 것은, 가공정밀도와 조립정밀도의 향상을 가져오나, 이와반대로 베인(3)이 로울러(5)의 외주면과 직접적인 접촉을 실시함에 따른 로울러 외경이 커지게 되는 효과를 수반하게 되어 원주속도가 커지면서 베인과 로울러간의 마모의 문제점이 대두하게 된다.In addition, according to the present invention, the rolling piston is formed integrally with the eccentric shaft to form one roller 5, which results in an improvement in processing precision and assembly precision, whereas the vanes 3 are formed on the roller 5 The direct contact with the outer circumferential surface is accompanied by the effect of increasing the outer diameter of the roller. As the circumferential speed increases, the problem of wear between the vanes and the rollers arises.
따라서 이와같은 점을 해소시켜 주기 위해 베인(3)에 형성된 하부측의 홈상에 끼워져 구름마찰을 실시하는 스틱롤러(6)의 원활한 운동을 유지하도록 베인(3) 상에 급유공(7)을 형성하여 계속적인 윤활공급이 이루어지도록 하였다.Therefore, in order to solve such a problem, the oil supply hole 7 is formed on the vane 3 so as to maintain smooth movement of the stick roller 6 which is inserted into the groove of the lower side formed in the vane 3 and performs rolling friction. To provide continuous lubrication.
이때, 베인(3)에 형성되는 급유공(7)의 형태는 제2도에 도시된 바와같이, 베인(3)의 하부홈과 스틱롤러(6)의 크기와 구름마찰에 따른 마모와 발열을 고려하여 다양하게 이를 변경할 수 있는데, 제2(a)도, 제2(b)도와 같이 베인(3)의 하부홈을 반구형으로 형성하여 주거나, 또는 제2(c)도, 제2(d)도와 같은 사다리꼴 단면을 갖도록 할 수 있으며, 또한 베인(3)내에 관통되는 급유공(7)을 제2(a)도, 제2(c)와 같이 수직형상으로 베인(3)의 상부면을 관통시키거나 또는 제2(b)도, 제2(d)도와 같이 베인(3)의 측면으로 통하도록 경사지게 할 수 있다.At this time, the shape of the oil supply hole (7) formed in the vanes (3), as shown in Figure 2, the size of the lower groove and the stick roller (6) of the vanes 3 and wear and heat generated by the rolling friction This can be changed in various ways, as shown in FIG. 2 (a), as shown in FIG. 2 (b), the lower groove of the vane 3 is formed in a hemispherical shape, or in the second (c), the second It is possible to have a trapezoidal cross section like a tile, and the oil supply hole 7 penetrated in the vane 3 penetrates the upper surface of the vane 3 in a vertical shape like the second (a) and the second (c). Alternatively, the second (b) may be inclined to pass through the side of the vane 3 as shown in the second (d).
이와같이 본 고안은 롤링피스톤과 편심축을 합하여 일체형으로 형성하여 줌에 따라 종래와 같이 롤링피스톤의 내면가공 또한 이에 접하는 편심축의 외주가공이 불필요하게 되어 가공 및 조립성을 향상시켜 주게 되고, 실린더 내면과 로울러간의 압축에 관련되는 간극의 공차관리가 종래의 롤링피스톤을 없애줌에 따라 훨신 간편해져 보다 정확한 간극상태로서 압축을 실시하게 되어 압축에 따른 압축가스의 누설을 줄이고, 이에따라 압축기의 전체적인 성능향상을 기할 수 있게 되는 효과를 갖는다.In this way, the present invention is formed by combining the rolling piston and the eccentric shaft to form an integrated body, and thus, the inner surface processing of the rolling piston and the outer circumferential processing of the eccentric shaft in contact with it are unnecessary. Tolerance management of the gap related to the compression of the liver is much simpler as it eliminates the conventional rolling piston, and the compression is performed as a more accurate gap state, thereby reducing the leakage of compressed gas due to compression, thereby improving the overall performance of the compressor. Has the effect of being.
