이상과 같이 구성된 본 고안에 따른 압축기의 플랜지 윤활장치의 구동되는 과정을 설명하면 다음과 같다.Referring to the driving process of the flange lubricator of the compressor according to the present invention configured as described above are as follows.
밀폐용기(10)와 체결된 상부플랜지(20)와 하부플랜지(30) 사이에 설치된 크랭크축(40)은 전동수단으로부터 회전력을 받아 고속으로 회전하게 된다. 한편 상부플랜지(20)의 접착면(21)과 하부플랜지(30)의 접착면(31) 사이에서 크랭크축(40)과 결합된 마찰감쇠판(50)은 밀착되어 회전하게 되며 이때 크랭크축(40)의 양단측면(42)에 형성된 계단홈(51)속에는 크랭크축(40)에 형성된 오일홈(41)으로부터 오일이 유입되어 마찰감쇠판(50)의 회전시 마찰감쇠판(50)과 밀착된 상부플랜지(20)의 접착면(21)과 하부플랜지(30)의 접착면(31)에 유막을 형성하게 하여 마찰마모를 감소시킨다.The crankshaft 40 installed between the upper flange 20 and the lower flange 30 coupled to the hermetic container 10 is rotated at a high speed by receiving rotational force from the power transmission means. Meanwhile, the friction damping plate 50 coupled with the crankshaft 40 is rotated between the adhesive face 21 of the upper flange 20 and the adhesive face 31 of the lower flange 30 to be in close contact with each other. The oil flows into the step grooves 51 formed on both end sides 42 of the 40 and oil-contacts from the oil grooves 41 formed on the crankshaft 40 to closely adhere to the friction damping plate 50 when the friction damping plate 50 rotates. The friction surface is reduced by forming an oil film on the adhesive surface 21 of the upper flange 20 and the adhesive surface 31 of the lower flange 30.
상부플랜지(20)와 하부플랜지(30) 사이에 위치한 압축실(61)에는 로울링피스턴(70)이 편심 회전하며 흡입, 압축, 토출과정을 거치면서 압축된 냉매는 응축기(미도시)로 보내어진다.In the compression chamber 61 located between the upper flange 20 and the lower flange 30, the rolling piston 70 is eccentrically rotated, and the compressed refrigerant is sent to a condenser (not shown) through suction, compression, and discharge processes. Lose.
이상에서 상세히 설명한 바와 같이 본 고안에 따른 압축기의 플랜지 윤활장치는 크랭크축(40)의 양단측면(42)와 상부플랜지(20)의 접착면(21)과 하부플랜지(30)의 접착면(31) 사이에 마찰감쇠판(50)을 설치하여 마찰감쇠판(50) 양면에 형성된 계단홈(51)의 오일 저장효과로 유막이 형성되어 종래 기술에 문제가 있었던 상부플랜지(20)의 접착면(21)과 하부플랜지(30)의 접착면(31)이 함께 밀착되어 회전하는 크랭크축(40)의 양단측면(42)에 발생한 마찰 마모를 최대한으로 줄일수 있고, 상부플랜지(20)의 접착면(21)과 하부플랜지(30)의 접착면(31)으로 냉매가스의 누출이 방지되므로 압축기의 냉매가스 압축효율을 높일수 있는 이점이 있다.As described in detail above, the flange lubrication apparatus of the compressor according to the present invention has both the end surfaces 42 of the crankshaft 40 and the adhesive surface 21 of the upper flange 20 and the adhesive surface 31 of the lower flange 30. The oil-tight film is formed by the oil storage effect of the step grooves 51 formed on both sides of the friction damping plate 50 by installing the friction damping plate 50 between the adhesive surfaces of the upper flange 20, which has been a problem in the prior art. 21 and the adhesive surface 31 of the lower flange 30 are in close contact with each other can reduce the frictional wear generated on both side surfaces 42 of the crankshaft 40 to rotate to the maximum, the adhesive surface of the upper flange 20 Since the leakage of the refrigerant gas is prevented by the adhesive surface 31 between the 21 and the lower flange 30, there is an advantage of increasing the refrigerant gas compression efficiency of the compressor.
