본 고안은 밀페형 전동압축기의 회전축에 관한 것으로, 특히 회전축의 구성을 개선하여 압축기의 초기 기동시 보다 실제 운전 상태시의 급유특성을 향상시켜 압축기의 성능과 내구성을 향상시킴을 특징으로 한 것이다.The present invention relates to a rotating shaft of a hermetic electric compressor, and in particular, to improve the configuration of the rotating shaft to improve the lubrication characteristics in the actual operating state than the initial startup of the compressor to improve the performance and durability of the compressor.
종래의 회전축은 제2도에서와 같이 몸체(1)가 강관으로되고 하단 내면에는 급유상승을 할 수 있도록 내부를 오무려 흡상부(2)를 형성시켰으며 상단에는 핀부(3)와 몸통(1)에는 구멍(4)(4a)를 형성하여 수직흡상통로(5)를 통해 윤활유(6)를 흡상시키게 한 것이다.In the conventional rotary shaft, as shown in FIG. 2, the body 1 is formed of a steel pipe, and the inside of the lower part is formed with a suction part 2 so as to allow oil supply to rise and the upper part of the pin part 3 and the body 1 ), Holes (4) (4a) are formed to suck the lubricant 6 through the vertical suction passage (5).
따라서 이 회전축(1)은 제1도에서와 같이 전동기부(7)와 프레임(8) 및 압축기구부(9)를 연동지지하게되고 압축기구부(9)에 봉입되어 있는 윤활유(6)는 회전축(1) 하단의 흡상부(2)에 의해 흡상시키게 된다.Accordingly, the rotary shaft 1 is interlocked to support the electric motor unit 7, the frame 8 and the compression mechanism 9 as shown in FIG. 1 and the lubricating oil 6 enclosed in the compression mechanism 9 is rotated. 1) It is made to suck up by the suction part 2 of a lower end.
즉, 전동기기부(7)의 전압인가에 의해 회전축(1)의 회전 원심력으로 윤활유(6)가 펌핑되어 회전축(1)이 흡상통로(5)를 통해 상승하여 상부의 핀(3)부로 토출시켜 습동부품의 윤활과 압축기구부(9)를 윤활시켜주며 일부는 물품(1)의 중간구멍부(4)(4a)를 통해 전동기부(7)와 습동부품들을 윤활시켜 주게된다.That is, the lubricating oil 6 is pumped by the rotational centrifugal force of the rotary shaft 1 by the application of the voltage of the electric machine unit 7, and the rotary shaft 1 rises through the suction passage 5 to discharge to the upper pin 3 part. Lubrication of the sliding parts and lubrication of the compression mechanism (9), and part of the lubrication of the electric motor (7) and the sliding parts through the middle hole (4) (4a) of the article (1).
그러나 상기의 회전축(1)은 하단에 오무려 놓은 흡상부(2)의 작용에 의해 윤활유가 흡상되고 흡상통로(5)가 수직으로한 형성되어 있기 때문에 윤활유(6)의 수직상승력으로 급유 성능이 크게 저하되므로서 냉장고의 경우에는 실제 운전상태에서 압축기내부의 윤활유(6) 온도는 60-80℃로 되어야 하는데 종래의 회전축(1), 즉 제4도에서와 같은 회전축(1)을 사용하므로 인해 압축기의 실제운전조건 60-80℃에서의 급유 특성이 초기 기동시의 유온 20-30℃보다 현저하게 떨어지는 현상을 보이며 초기 기동시 너무많은 급유를 하므로서 초기 기동부하가 크게 걸려 입력손실과 압축기의 성능을 크게 저하시키게되는 문제점이 있었다.However, since the lubricating oil is sucked up by the action of the suction part 2 recessed at the lower end and the suction passage 5 is formed vertically, the rotation shaft 1 has a lubricating performance due to the vertical rising force of the lubricating oil 6. In the case of the refrigerator, the temperature of the lubricating oil 6 inside the compressor should be 60-80 ° C. in the case of a refrigerator, because it is greatly deteriorated. The characteristics of lubrication at the actual operating condition of the compressor at 60-80 ℃ are markedly lower than the oil temperature of 20-30 ℃ at the initial start-up and too much lubrication at the initial start-up. There was a problem that greatly lowers.
따라서 본 고안은 이와같은 종래의 문제점을 해결하기 위해 회전축을 개선시켜 실제 운전상태에서의 급유특성을 향상하므로서 압축기의 초기 기동특성을 좋게하고 압축기의 성능 및 내구성을 향상시키는 것을 목적으로 한바, 이를 첨부 도면에 의해 상세히 설명하면 다음과 같다.Therefore, the present invention aims to improve the initial starting characteristics of the compressor and improve the performance and durability of the compressor by improving the rotational shaft to improve the lubrication characteristics in the actual operation state to solve such a conventional problem. When described in detail by the drawings as follows.
밀페형 전동압축기의 회전축에 있어서, 몸체(1) 하단내면에 안내요홈(10)를 형성하여 몸체가 반바퀴정도 비틀린 급유 보조판(11)을 장착하되 ""형의 스프링(12)으로 고정시키고, 안내요홈(10)의 직상단에는 경사각으로된 흡상통로(13)를 형성시키서 된 것이다.In the rotary shaft of the hermetic electric compressor, the guide groove (10) is formed in the lower inner surface of the body (1) so that the body is fitted with a refueling auxiliary plate (11) twisted about half a turn. It is fixed by the spring 12 of the ", and the suction passage 13 of the inclined angle is formed on the upper end of the guide groove 10.
이와 같이된 본 고안은 전동기구부(7)와 프레임(8)및 압축기구부(9)를 연동지지하는 회전축(1)을 제3도에서와 같이 안내요홈(10)과 경사각의 흡상통로(13)를 갖게하므로서 압축기 내부에 봉입되어 있는 윤활유(6)를 회전축(1) 하단내면의 안내요홈(10)에 장착된 급유보조판(11)에 의해 1차 펌핑되게 하고 펌핑된 윤활유(6)는 회전축(1)의 회전원심력에 의해 2차 상승되게 한다.The present invention as described above has a rotating shaft (1) for interlocking the power mechanism (7), the frame (8) and the compression mechanism (9) as shown in FIG. In order to ensure that the lubricating oil (6) enclosed in the compressor is primarily pumped by the lubrication auxiliary plate (11) mounted on the guide groove (10) of the lower inner surface of the rotary shaft (1) and the pumped lubricating oil (6) is the rotary shaft ( Secondary rise by the centrifugal force of 1).
이때 안내요홈(10)의 직상단에는 일정각도의 경사흡상통로(13)를 형성하므로서 상승력이 증가되고 수직상승력을 한층 더 증가시키기 위해 회전축(1)의 내경과 비례를 일정비율로 해주므로서 습동부품의 윤활은 물론 상단의 핀부(3)로 토출되는 윤활유(6)는 압축기구부(9)를 충분히 윤활시켜주고 떨어지는 윤활유(6)는 전동기구부(7)를 냉각시켜주게 된다.At this time, by forming an inclined suction passage 13 of a predetermined angle at the upper end of the guide groove 10, the lifting force is increased, and the inner diameter and proportion of the rotating shaft 1 are increased at a constant ratio in order to further increase the vertical lifting force. The lubricating oil 6 discharged to the pin part 3 of the upper part as well as the lubrication of the parts sufficiently lubricates the compression mechanism 9, and the falling lubricating oil 6 cools the electric mechanism 7.
즉, 회전축(1)에 안내요홈(10)을 형성하여 비틀림형상의 급유보조판(11)을 장착하므로서 윤활유(6)를 1차강제 펌핑하게 되고, 안내요홈(10)의 직상단 흡상통로(13)를 일정각도의 경사각을 갖게하므로서 2차 상승력을 부여하게 되며 수직상승력을 한층 더 강화사키기 위해 회전축(1)의 내경 대 외경의 비례를 일정하게 하므로서 3차로 상승력을 부여받게 되는 것이다.That is, the guide groove 10 is formed on the rotating shaft 1 to install the torsion-shaped oil supply auxiliary plate 11 to pump the lubricant 6 primarily, and the suction passage 13 directly above the guide groove 10 is provided. ) To give the secondary lift force by having a certain angle of inclination angle, and to increase the vertical lifting force to further strengthen the vertical lift force is to be given a third lift force by the constant proportion of the inner diameter to the outer diameter of the rotating shaft (1).
때문에 압축기(9)내부 및 전동기부(7)의 윤활과 냉각효과는 더욱더 증가되게 되는 것이다.Therefore, the lubrication and cooling effects of the compressor 9 and the motor unit 7 are further increased.
이와 같이된 본 고안의 회전축(1)을 사용하므로 인해 초기 기동시의 압축기 내부 윤활유 온도를 20-30℃로 유지하게 하여 초기 기동특성을 좋게하고 압축기 실제운전상태(압축기 내부의 윤활유 온도 60-80℃)에서의 급유특성을 향상시켜 압축기(9)내부 및 전동기구부(7)의 냉각기능을 향상시키게 되므로서 압축기(9)의 효율증대는 물론 내구성을 증대시키게 되며 흡상통로(13) 직하위치인 안내요홈(10)에 설치한 급유보조판(11)을 스프링(12)으로 고정시키므로서 회전압력을 받아도 유동없이 고정될 수 있고 이탈될 우려가 없이 사용될수 있는 것이다.Since the rotary shaft 1 of the present invention is used as described above, it is possible to maintain the compressor internal lubricating oil temperature at 20-30 ° C. at the initial startup, thereby improving the initial starting characteristics and the actual operation state of the compressor (lubricating oil temperature 60-80 in the compressor). By improving the lubrication characteristics of the compressor (9) and the cooling mechanism of the compressor mechanism (7), the efficiency of the compressor (9) is increased as well as the durability, and the position under the suction passage (13) is improved. Since the oil supply auxiliary plate 11 installed in the guide groove 10 is fixed with a spring 12, it can be fixed without flow even under rotational pressure and can be used without fear of being separated.
