In particular, the oil of the compressor is configured to smoothly operate by supplying sufficient oil to each friction part such as a rotating shaft or a piston. It relates to a pickup device.
일반적으로 밀폐형 압축기는 제 1 도에 도시한 바와같이 케이스(1)의 내측에는 고정자(2)가 고정설치되어 있고, 상기 고정자(2)의 내측에는 회전축(3)을 갖는 회전자(4)가 회전자유롭게 설치되어 있으며, 상기 회전축(3)의 하측에 편심형성된 크랭트축(3a)에는 선단에 피스톤(5)을 결합시킨 커넥팅로드(6)가 결합되어 있고, 상기 피스톤(5)은 실린더(7)내에서 슬라이드작동하면서 냉매등의 유체를 압축시키도록 구성되어 있다.Generally, in the hermetic compressor, as illustrated in FIG. 1, a stator 2 is fixedly installed inside the case 1, and a rotor 4 having a rotation shaft 3 is provided inside the stator 2. Rotating freely installed, the connecting rod 6 is coupled to the crank shaft (3a) eccentrically formed on the lower side of the rotary shaft 3, the piston 5 is coupled to the front end, the piston (5) is a cylinder (7) It is configured to compress the fluid such as the refrigerant while the slide operation within the cylinder.
그리고, 상기 회전축(3)은 베어링부재(8)에 의해 회전자유롭게 지지되어 있고, 상기 크랭크축(3a)의 하단에는 제 2 도에 도시한 바와같이 케이스(1)의 하단에 저류된 오일(9)을 회전축(3)의 원심력에 의해 펌핑하도록 하측에 유입구(10a)를 형성시킨 픽업수단(10)이 결합되어 있으며, 상기 회전축(3)의 내측과 그 외주면에는 상기 픽업수단(10)의 작동에 따라 유입된 오일(9)을 상측으로 공급하는 나선형상의 급유공(3b)이 형성되어 있다.In addition, the rotating shaft 3 is freely supported by the bearing member 8, and at the lower end of the crank shaft 3a, the oil 9 stored at the lower end of the case 1 as shown in FIG. ) Is coupled to the pickup means 10 is formed in the inlet (10a) in the lower side to be pumped by the centrifugal force of the rotary shaft (3), the inner and outer peripheral surfaces of the rotary shaft (3) operation of the pickup means (10) As a result, a spiral oil supply hole 3b for supplying the oil 9 introduced therein is formed.
따라서, 고정자(2)에 전류가 인가됨에 따라 형성되는 자장에 의해 회전자(4) 및 회전축(3)이 회전작동하면, 상기 회전축(3)과 일체로 회전되는 크랭크축(3a)의 편심회전에 의해 커넥팅로드(6)가 회전운동을 직선운동으로 변환시키면서 피스톤(5)을 직선왕복운동시켜 실린더(7)내의 유체를 압축하여 토출시키게 되며, 상기 회전축(3)과 일체로 회전되는 픽업수단(10)은 케이스(1)내에 저류된 오일 (9)을 유입구(10a)내로 상스시켜 급유공(3b)을 통하여 회전축(3) 및 피스톤(5)의 각 마찰부로 급유함으로써 원활한 윤활작용이 이루어지도록 하고 있다.Therefore, when the rotor 4 and the rotation shaft 3 rotate by the magnetic field formed by applying the current to the stator 2, the eccentric rotation of the crank shaft 3a which is integrally rotated with the rotation shaft 3 By the connecting rod 6 converts the rotational movement into a linear movement, the piston (5) is linear reciprocating movement to compress and discharge the fluid in the cylinder (7), the pickup means rotated integrally with the rotary shaft (3) (10) smoothly lubricates the oil (9) stored in the case (1) into the inlet (10a) to lubricate the rotating shaft (3) and the respective friction parts of the piston (5) through the oil supply hole (3b).

When the compressor is stopped, the oil flowing into the lubrication hole and the pickup means is discharged, so that the residual amount of oil is not sufficient at the initial startup, so that the starting load is increased, and thus the compression efficiency of the fluid is significantly reduced. .
본 발명은 상술한 종래기술의 문제점들을 해결하기 위하여 안출된 것으로서, 본 발명의 목적은 오일의 공급이 원활하게 이루어지도록함과 동시에 각 마찰부에 오일의 잔류량을 증대시켜 초기기동시의 기동부하를 최소화하고 마찰에 의한 마모량을 현저하게 절감할 수 있는 압축기의 오일픽업장치를 제공하는데 있다.The present invention has been made to solve the above-mentioned problems of the prior art, the object of the present invention is to provide a smooth supply of oil and at the same time increase the residual amount of oil in each friction portion to increase the starting load at initial startup To provide an oil pick-up device of the compressor that can minimize and significantly reduce the amount of friction due to wear.
이와같은 목적을 실현하기 위하여 이루어진 본 발명에 따른 압축기의 오일픽업장치는 회전축과, 상기 회전축의 작동에 따라 케이스내의 오일을 펌핑하여 각 마찰부로 급유하는 픽업수단을 구비한 압축기에 있어서, 상기 픽업수단은 오일이 유입되는 유입공을 형성시킨 관부재와, 상기 관부재내에 삽입설치되어 유입된 오일을 회전축 및 피스톤의 마찰부로 공급하는 급유통로가 형성된 내부부재로 이루어져 픽업수단내로 유입된 오일를 펌핑하여 각 마찰부로 공급함으로써 윤활작용이 더욱 원활하게 이루어지고, 압축기의 정지시에는 각 마찰부에 잔류하는 오일의 량을 증대시켜 초기기동시의 기동부하를 최소화함으로써 초기기동이 더욱 원활하게 이루어짐과 동시에 압축효율을 현저하게 향상시킬 수 있는 것을 그 특징으로 한다.An oil pick-up apparatus for a compressor according to the present invention made to achieve the above object comprises: a pickup having a rotating shaft and a pickup means for pumping oil in a case according to the operation of the rotating shaft to supply oil to each friction portion.

이하, 본 발명의 바람직한 일실시예를 첨부된 도면 제 3 도 내지 제 5 도에 따라서 더욱 상세하게 설명한다.Hereinafter, a preferred embodiment of the present invention will be described in more detail with reference to FIGS. 3 to 5.
도면에서 종래의 구성과 동일한 구성에 대해서는 동일명칭 및 동일부호를 부여하고, 그에 대한 상세한 설명은 생략한다.In the drawings, the same components as those in the related art are denoted by the same names and the same reference numerals, and detailed description thereof will be omitted.
먼저, 회전축(3)의 하측에 편심지게 형성된 크랭크축(3a)의 하측에는 케이스(1)내에 저류된 오일(9)을 펌핑하여 회전축(3) 및 피스톤(5)등의 각 마찰부로 공급하는 픽업수단(20)이 일측으로 경사지게 결합되어 있다.First, the oil 9 stored in the case 1 is pumped to the lower side of the crankshaft 3a which is formed eccentrically below the rotating shaft 3 to supply to each friction part such as the rotating shaft 3 and the piston 5. Pick-up means 20 is inclined to one side is coupled.
상기 픽업수단(20)은 케이스(1)내에 저류된 오일(9)의 유입이 가능하도록 다수의 유입공(22a)을 형성시킨 관부재(22)와, 상기 관부재(22)의 내측에 삽입설치되며 외주면에 나선형상의 급유통로(24a)가 형성된 내부부재(24)로 이루어 진다.The pickup means 20 is a tube member 22 formed with a plurality of inlet holes (22a) to enable the inflow of the oil (9) stored in the case (1), and is inserted into the inside of the tube member 22 It is installed and consists of an inner member 24 formed with a spiral oil supply passage 24a on the outer circumferential surface.
상기 급유통로(24a)는 상기 유입공(22a)으로 부터 유입된 오일(9)을 회전되는 원심력에 의해 급유공(3b)을 통하여 상측으로 공급하게 되며, 상기 급유공(3b)을 통하여 공급되는 오일(9)은 회전축(3)과 베어링부재(8)의 마찰부 및 피스톤(5)과 실린더(7)등의 각 마찰부로 급유를 행하게 되는 것이다.The oil supply passage 24a supplies the oil 9 introduced from the inflow hole 22a upward through the oil supply hole 3b by the centrifugal force rotated, and is supplied through the oil supply hole 3b. The oil (9) is to be lubricated to the friction portion of the rotary shaft 3 and the bearing member (8) and each friction portion such as the piston (5) and the cylinder (7).
그리고, 상기 관부재(22)의 내측에 삽입설치되는 내부부재(24)는 관부재(22)보다 짧은 길이로 형성됨이 바람직하며, 이에따라 관부재(22)의 하측에는 오일(9)의 유입이 더욱 원활하게 이루어질 수 있도록 수용부(22b)가 형성되어 있다.In addition, the inner member 24 inserted into the inner side of the tubular member 22 is preferably formed to have a shorter length than the tubular member 22. Accordingly, the inflow of oil 9 is lower than the tubular member 22. The receiving portion 22b is formed to be more smoothly.
본 실시예에서는 관부재(22)에 형성된 유입공(22a)을 상기 급유통로(24a)와 연통되도록 양측에 2개를 형성하고 있으나, 이에 한정하는 것은 아니며 예컨대 하나 또는 2개이상의 유입공(22a)을 급유통로(24a)와 연통되도록 형성시킬 수도 있다.In the present embodiment, two inflow holes 22a formed in the pipe member 22 are formed at both sides so as to communicate with the oil supply passage 24a, but the present invention is not limited thereto. For example, one or two inflow holes ( 22a) may be formed to communicate with the oil supply passage 24a.
한편, 상기 급유통로(24a)내로 급유된 오일(9)은 크랭크축(3a) 및 회전축(3)에 형성된 급유통로(24a)를 통하여 각 마찰부로 급유되는 것이다.On the other hand, the oil (9) supplied into the oil supply passage (24a) is to be supplied to each friction portion through the oil supply passage (24a) formed on the crank shaft (3a) and the rotating shaft (3).
그리고, 본 실시예에서는 내부부재(24)의 외주면에 오일(9)이 공급되는 급유통로(24a)를 나선형상으로 형성하고 있으나 이에 한정하는 것은 아니며, 예컨대 오일(9)의 유통이 가능하도록 상기 관부재(22)의 내주면에 형성시킬 수도 있음은 물론이다.In this embodiment, the oil supply passage 24a in which the oil 9 is supplied to the outer circumferential surface of the inner member 24 is formed in a spiral shape, but is not limited thereto. For example, the oil 9 may be distributed. Of course, it may be formed on the inner peripheral surface of the pipe member 22.
도면중 미설명부호 26은 냉매등의 유체의 흡입시 소음이나 진동등의 발생을 감쇄시키는 흡입머플러를 나타내고 있다.In the drawing, reference numeral 26 denotes a suction muffler that reduces the occurrence of noise or vibration when suction of fluid such as a refrigerant.
다음에 이와같이 구성된 본 발명에 따른 압축기의 오일픽업장치에 대한 작용 및 효과를 설명한다.Next will be described the operation and effect of the compressor according to the present invention configured as described above for the oil pickup device.
먼저, 회전축(3)의 회전작동에 따라 크랭크축(3a)이 편심회전작동을 행하면 커넥팅로드(6)가 회전운동을 직선왕복운동으로 변환시킴에 따라 피스톤(5)이 실린더(7)내에서 직선왕복작동을 행하게 되며, 이에 따라 흡입머플러(26)를 통하여 상기 실린더(7)내로 흡입된 냉매등의 유체가 압축되는 작동을 반복적으로 행하게 되는 것이다.First, when the crankshaft 3a performs the eccentric rotation operation in accordance with the rotation operation of the rotation shaft 3, the piston 5 in the cylinder 7 as the connecting rod 6 converts the rotation movement into a linear reciprocation movement. The linear reciprocating operation is performed, and thus the operation of repeatedly compressing a fluid such as a refrigerant sucked into the cylinder 7 through the suction muffler 26 is performed.
그리고, 상기 회전축(3) 및 크랭크축(3a)이 회전작동함에 따라 상기 크랭크축(3a)의 하측에 결합된 픽업수단(20)도 편심회전을 행하게되며, 상기 픽업수단(20)이 편심회전을 행함과 동시에 케이스(1)의 내측에 저류된 오일(9)은 펌핑되어 회전축(3) 및 피스톤(5)의 각 마찰부로 급유된다.In addition, as the rotary shaft 3 and the crank shaft 3a are rotated, the pickup means 20 coupled to the lower side of the crank shaft 3a also performs eccentric rotation, and the pickup means 20 is eccentrically rotated. At the same time, the oil 9 stored inside the case 1 is pumped and lubricated to each of the friction parts of the rotary shaft 3 and the piston 5.
즉, 상기 픽업수단(20)의 편심회전에 따라 관부재(22)에 형성된 다수의 유입공(22a) 및 수용부(22b)내로 유입된 오일(9)은 내부부재(24)의 외주면에 형성된 급유통로(24a)를 통하여 상측으로 공급되며, 상기 급유통로(24a)를 통하여 상측으로 공급되는 오일(9)은 급유공(3b)을 통하여 회전축(3)과 베어링부재(8) 및 피스톤(5)과 실린더(7)의 각 마찰부로 공급됨으로써 급유가 이루어져 원활한 작동이 이루어지게 되는 것이다.That is, the oil 9 introduced into the plurality of inflow holes 22a and the receiving portion 22b formed in the pipe member 22 according to the eccentric rotation of the pickup means 20 is formed on the outer circumferential surface of the inner member 24. The oil (9) supplied upward through the oil supply passage (24a) and supplied upward through the oil supply passage (24a) is the rotary shaft (3), the bearing member (8), and the piston through the oil supply hole (3b). Supplying to each friction portion of the (5) and the cylinder (7) is to provide lubrication is made smooth operation.
이때, 상기 급유통로(24a)내로 유입된 오일(9)은 픽업수단(20)의 회전에 따라 작용하는 원심력에 의해 나선형상의 급유통로(24a)내를 따라서 상승하게 됨으로써 오일(9)의 공급이 더욱 원활하게 이루어지게 된다.At this time, the oil (9) introduced into the oil supply passage (24a) is raised along the inside of the spiral oil supply passage (24a) by the centrifugal force acting in accordance with the rotation of the pickup means 20 of the oil (9) Supply is made more smoothly.
한편, 압축기의 정지시에는 회전축(3) 및 픽업부재(20)의 회전작동도 정지하게 되며, 이에따라 관부재(22)에는 원심력이 작용하지 않게됨으로써 급유공(3b) 및 급유통로(24a)내에 저류된 오일(9)은 케이스(1)내에 저류된 오일(9)의 압력에 의해 하측으로 배축되지 않고 상기 급유공(3a) 및 급유통로 (24a)내에 잔류하게 되는 것이다.On the other hand, when the compressor is stopped, the rotational operation of the rotary shaft 3 and the pickup member 20 is also stopped. Accordingly, the centrifugal force is not applied to the pipe member 22, so that the oil supply hole 3b and the oil supply passage 24a are stopped. The oil 9 stored therein remains in the oil supply hole 3a and the oil supply passage 24a without being contracted downward by the pressure of the oil 9 stored in the case 1.
따라서, 초기기동시에는 급유공(3a) 및 급유통로(24a)내에 잔류된 오일(9)이 회전축(3) 및 픽업부재(20)의 회전작동에 따라 작용하는 원심력에 의해 각 마찰부로 급유되고, 이에따라 기동부하가 최소화되어 초기기동이 원활하게 이루어짐으로써 압축효율이 현저하게 향상되는 것이다.Therefore, at initial startup, the oil 9 remaining in the oil supply hole 3a and the oil supply passage 24a is lubricated to each friction part by centrifugal force acting according to the rotation operation of the rotation shaft 3 and the pickup member 20. As a result, the starting load is minimized so that the initial starting is smoothly performed, and the compression efficiency is remarkably improved.
상술한 바와같이 본 발명에 따른 압축기의 오일픽업장치에 의하면, 픽업수단내로 유입된 오일을 펌핑하여 각 마찰부로 공급함으로써 윤활작용이 더욱 원활하게 이루어지고, 압축기의 정지시에는 각 마찰부에 잔류하는 오일의 량을 증대시켜 초기기동시의 기동부하를 최소화함으로써 초기기동이 더욱 원활하게 이루어짐과 동시에 압축효율을 현저하게 향상시킬 수 있는 등의 탁월한 이점을 갖는다.As described above, according to the oil pick-up apparatus of the compressor according to the present invention, the oil introduced into the pickup means is pumped and supplied to each friction portion, so that lubrication is more smoothly performed. By increasing the amount of oil and minimizing the starting load during initial startup, the initial startup is more smooth and the compression efficiency can be remarkably improved.
