Description
본 발명은 스크롤 압축기의 올담링에 관한 것으로, 특히 올담링을 개재하여도 올담링에 접하는 메인프레임의 오일 유통이 가능해지는 오일 유통부를 가지는 스크롤 압축기의 올담링에 관한 것이다.The present invention relates to an old dam ring of a scroll compressor, and more particularly, to an old dam ring of a scroll compressor having an oil distribution portion that enables oil distribution of a mainframe in contact with the old dam ring even through the old dam ring.
일반적으로 스크롤식 압축기는 공조기 분야에 널리 적용하는 고효율 저소음 압축기로서, 두 개의 스크롤이 상대 선회운동을 하면서 스크롤 사이에 복수 개의 압축실을 쌍으로 형성하고, 이 압축실이 지속적으로 중심방향으로 이동하면서 체적이 작아져 냉매가스를 연속으로 흡입 압축하여 토출하는 방식이다.In general, a scroll compressor is a high-efficiency low noise compressor widely applied to an air conditioner. A plurality of compression chambers are formed in pairs between scrolls while the two scrolls rotate relative to each other, and the compression chamber continuously moves toward the center. The volume decreases and the refrigerant gas is continuously sucked and compressed to be discharged.
두 개의 스크롤이 상대 선회운동을 하기 위하여는 두 스크롤 사이 또는 회전운동을 하는 스크롤과 이를 지지하는 프레임 사이에 올담링(Oldham's Coupling)이라고 하는 자전 방지 기구를 개재하여 자전하려는 스크롤을 강제로 일정 선회 궤적을 가지게 선회 운동시켜 압축실의 체적이 연속으로 가변되도록 하는 것이다. 따라서, 올담링과 이를 지지하는 선회스크롤이나 프레임 사이에는 미끄럼부가 발생하며 이 미끄럼부의 윤활 상태는 압축기의 성능과 밀접한 관련이 있다.In order to make the two scrolls rotate relative to each other, or between the two scrolls or the rotating scroll and the supporting frame, the scrolls are forced to rotate through the anti-rotation mechanism called Oldham's Coupling. The pivoting motion is to change the volume of the compression chamber continuously. Therefore, a slip occurs between the old dam ring and the turning scroll or frame supporting the slip ring, and the lubrication state of the slip is closely related to the performance of the compressor.

도면중 미설명 부호인 4a는 오일유로, P는 압축실이다. In the figure, reference numeral 4a denotes an oil oil, and P denotes a compression chamber.
상기와 같은 종래의 스크롤 압축기는 다음과 같이 동작한다.The conventional scroll compressor as described above operates as follows.
즉, 구동모터(미도시)에 전원을 인가하면 구동모터에 압입한 구동축(4)이 회전을 하여 선회스크롤(3)이 올담링(5)에 의해 편심거리 만큼 선회하고, 이와 함께 선회스크롤(3)은 고정스크롤(2)과의 랩(2a)(3a) 사이에 복수 개의 압축실(P)을 형성하며, 이 압축실(P)은 선회스크롤(3)의 지속적인 선회운동에 의해 중심으로 이동하면서 체적이 감소하여 냉매가스를 흡입 압축하여 토출한다.That is, when power is applied to the drive motor (not shown), the drive shaft 4 press-fitted to the drive motor rotates so that the turning scroll 3 turns by an eccentric distance by the old dam ring 5, and the turning scroll ( 3) a plurality of compression chambers (P) are formed between the wrap (2a) (3a) and the fixed scroll (2), the compression chamber (P) is centered by the continuous turning motion of the turning scroll (3) As the volume moves, the volume decreases, and the refrigerant gas is sucked and discharged.
이때, 구동축(4)이 고속으로 회전을 하면서 케이싱의 바닥에 채운 오일을 흡입하여 오일유로(4a)를 통해 상단으로 흡상하고, 이 오일은 구동축(4)의 상단에서 비산하여 일부는 메인프레임(1)과 구동축(4) 사이의 미끄럼부위를 윤활하는 한편 일부는 메인프레임(1)과 선회스크롤(3) 사이의 미끄럼부위를 윤활하여 압축기가 원활하게 동작되도록 하는 것이었다.At this time, while the drive shaft 4 rotates at a high speed, the oil filled in the bottom of the casing is sucked up and sucked up to the top through the oil passage 4a, and this oil is scattered from the top of the drive shaft 4, and a part of the main frame ( While lubricating the sliding portion between 1) and the drive shaft (4) while some lubricated the sliding portion between the main frame (1) and the turning scroll (3) to ensure that the compressor operates smoothly.
그러나, 상기와 같은 종래 스크롤 압축기에서는, 올담링키홈(1c)(1c)에 삽입되어 그를 따라서 왕복 이동하는 올담링(5)의 올담링키(5b)(5b)의 이동 시에 올담링키홈(1c)(1c)에 고인 오일은 올담링키홈(1c)(1c)과 메인프레임(1)의 환형돌부(1d)에 의해 압축되게 된다.However, in the conventional scroll compressor as described above, the old damling key groove 1c is inserted when the old dam ring keys 5b and 5b of the old dam ring 5 are inserted into the old dam ring key grooves 1c and 1c and reciprocated along them. The oil accumulated in the) 1c is compressed by the old damring key grooves 1c and 1c and the annular protrusion 1d of the main frame 1.
이러한 오일의 압축에 따라, 구동모터를 구동하여 구동축(4)을 회전시키고 그에 따라 선회스크롤(3)이 올담링(5)에 의해 편심거리 만큼 선회하게 하기 위한 입력이 증대된다. As the oil is compressed, the input for driving the drive motor to rotate the drive shaft 4 and thereby causing the turning scroll 3 to turn by the eccentric distance by the old dam ring 5 is increased.
이러한 입력의 증대는 압축기의 전체적인 효율을 떨어뜨리는 것으로서 이에 대한 개선의 필요성이 꾸준히 제기되고 있다.This increase in input reduces the overall efficiency of the compressor, and the need for improvement is steadily raised.

선회스크롤(30)은 원판모양으로 형성하여 그 상면은 랩(30a)이 나선형으로 형성된다. 선회스크롤(30)의 저면부 중앙에는 상기한 메인프레임(10)의 축구멍(10a)에 삽입되어 구동축의 상단에 편심 결합하는 보스부(30b)가 형성되고, 보스부(30b)의 주변에는 올담링(50)의 자전방지돌기(50c)(50c)가 일정 궤적 안에서 반경방향으로 미끄러지도록 삽입되는 자전방지홈(30c)(30c)이 형성된다.The revolving scroll 30 is formed in a disc shape, and the wrap surface 30a is spirally formed on the upper surface thereof. In the center of the bottom portion of the turning scroll 30, a boss portion 30b inserted into the shaft hole 10a of the main frame 10 and eccentrically coupled to the upper end of the driving shaft is formed, and around the boss portion 30b. The anti-rotation protrusions 50c and 50c of the old dam ring 50 are formed so that the anti-rotation grooves 30c and 30c are inserted to slide radially in a predetermined trajectory.
선회스크롤(30)의 자전방지홈(30c)(30c)은 메인프레임(10)의 올담링키홈(10c)(10c)과 직교하는 위치에 형성하고 있다.The anti-rotation grooves 30c and 30c of the orbiting scroll 30 are formed at positions perpendicular to the old damling key grooves 10c and 10c of the main frame 10.
올담링(50)은 링몸체(50a)를 환형으로 형성하여 그 저면의 좌우 양측에는 상기한 메인프레임(10)의 올담링키홈(10c)(10c)에 반경방향으로 미끄러지도록 올담링키(50b)(50b)를 돌출 형성하고, 상면의 전후 양측에는 상기한 올담링키(50b)(50b)와 직교하는 위치에 상기 선회스크롤(30)의 자전방지홈(30c)(30c)과 반경방향으로 미끄러지도록 자전방지돌기(50c)(50c)를 돌출 형성하고 있다.The Oldham ring 50 has an annular ring body 50a formed in an annular shape so as to slide radially in the old Damling key grooves 10c and 10c of the main frame 10 on both left and right sides of the bottom surface thereof. 50b is formed to protrude, and on both front and rear sides of the upper surface so as to slide radially with the anti-rotation grooves 30c and 30c of the turning scroll 30 at a position orthogonal to the old damling keys 50b and 50b. The anti-rotation protrusions 50c and 50c are formed to protrude.
이러한 올담링(50)의 올담링키(50b)(50b)가 환형돌부(10b)에 접근함에 따라 올담링키홈(10c)(10c)에 고인 오일이 압축되어 올담링키(50b)(50b)의 이동에 저항으로서 작용하는 것을 방지하기 위하기 위하여, 본 발명자는 올담링키(50b)(50b)에 오일유통부를 형성하는 구조를 제안하고자 한다.As the old damring keys 50b and 50b of the old dam ring 50 approach the annular protrusion 10b, the oil accumulated in the old dam ring key grooves 10c and 10c is compressed to move the old damring keys 50b and 50b. In order to prevent it from acting as a resistance to the present invention, the present inventors propose a structure for forming an oil distribution portion in the Old Damlinki (50b) (50b).
이러한 오일유통부로서, 본 도면에 예시된 바와 같이, 올담링키홈(10c)(10c)에 삽입되어 이동하는 올담링키(50b)(50b)를 관통하여 오일유통홀(50b')(50b')을 형성한다. As such an oil distribution part, as illustrated in the figure, the oil distribution hole 50b 'and 50b' penetrates through the old Damling key 50b and 50b which are inserted into and move into the Old Damling key groove 10c and 10c. To form.
오일유통홀(50b')(50b')을 형성함으로써, 올담링키(50b)(50b)가 메임프레임(10)의 환형돌부(10d)에 접근하도록 이동하게 되면, 올담링키홈(10c)(10c)에 고인 오일은 올담링키(50b)(50b)의 오일유통홀(50b')(50b')을 통해서 올담링키(50b)(50b)의 이동 방향과 반대 방향 즉, 메인프레임(10)의 반경방향으로 흐를 수 있게 된다.By forming the oil distribution holes 50b 'and 50b', when the old damring keys 50b and 50b are moved to approach the annular protrusion 10d of the main frame 10, the old damling key grooves 10c and 10c. The oil accumulated in) is opposite to the direction of movement of the Old Damlink keys 50b and 50b through the oil distribution holes 50b 'and 50b' of the Old Damlink keys 50b and 50b, that is, the radius of the main frame 10. It can flow in the direction.
그에 따라, 올담링키(50b)(50b)와 메임프레임(10) 사이에서 발생하였던 오일 압축에 의한 올담링키(50b)(50b)의 이동 저항이 극복되게 된다. 이렇게 올담링키(50b)(50b)의 이동 저항이 줄어들기에, 올담링키(50b)(50b)의 이동을 일으키는 입력을 저감할 수 있게 되어 압축기의 효율이 개선된다.As a result, the transfer resistance of the old damling keys 50b and 50b due to the oil compression occurring between the old damling keys 50b and 50b and the main frame 10 is overcome. Since the movement resistance of the Old Damlink keys 50b and 50b is reduced in this way, the input causing the shift of the Old Damlink keys 50b and 50b can be reduced, thereby improving the efficiency of the compressor.
다음으로, 도 4를 참조하여 올담링키에 형성되는 오일 유통부의 다른 실시예를 살펴보자. Next, referring to FIG. 4, another embodiment of an oil distribution unit formed in Oldham Linkee will be described.
도 4는 도 3의 올담링에 대한 다른 실시예를 보인 사시도이다.4 is a perspective view showing another embodiment of the old damling of FIG. 3.
도 4(a)에 도시된 바와 같이, 오일 유통부는 올담링(60)의 올담링키(60b)의 저면부에서 메임프레임(10)의 올담링키홈(10c)를 따라는 방향으로 요입된 오일유통단차부(60b')를 가진다.As shown in Figure 4 (a), the oil distribution in the oil distribution in the direction along the old damling key groove 10c of the main frame 10 at the bottom portion of the Old Damling key 60b of the Old Damling 60 It has a step part 60b '.
이러한 오일유통단차부(60b')는, 앞선 실시예의 경우와 동일하게 오일 압축에 의한 저항을 저감하는 기능을 수행하면서도 가공이 용이한 이점이 있다. 다시 말하자면, 오일유통홀(50b')을 가공하기 위하여 홈을 파는 것 보다는 오일유통단차부(60b')를 형성하기 위하여 일 부분을 깎아내는 것이 보다 수월하다는 것이다.The oil distribution step part 60b 'has the advantage of being easy to process while performing a function of reducing resistance due to oil compression as in the case of the previous embodiment. In other words, it is easier to cut off a part to form an oil distribution step 60b 'than to dig a groove to process the oil distribution hole 50b'.
도 4(b)에서는, 올담링(70)의 올담림키(70b)의 양 모서리부가 절개된 형태(70b')로 형성된 오일 유통부가 예시되어 있다.In FIG. 4 (b), an oil distributor formed in a form 70 b ′ in which both edge portions of the old dam key 70 b of the old dam ring 70 are cut is illustrated.
이러한 절개된 형태(70b')는 앞선 오일 유통부(50b',60b')의 경우 보다 그 가동이 더욱 용이하며, 그들과 동일한 기능을 수행한다.This cut out form 70b 'is easier to operate than the previous oil distributions 50b' and 60b ', and performs the same function as them.
이상에서 상술한 바와 같이, 본 발명에 따르는 오일 유통부를 가지는 스크롤 압축기의 올담링은, 올담링이 메인프레임 상에서 이동하는 중에 발생하는 오일 압축에 의한 저항을 저감한다.As described above, the old dam ring of the scroll compressor having the oil distributor according to the present invention reduces the resistance due to oil compression generated while the old dam ring moves on the mainframe.
이러한 저항의 저감은 올담링을 이동시키기 위해서 요구되는 입력의 저감을 가져오게 되고, 그 결과로서 전체적인 압축기의 효율을 개선할 수 있게 된다.This reduction in resistance results in a reduction in the input required to move the old dam ring, and as a result it is possible to improve the overall compressor efficiency.
