Abstract

본 발명에 의한 스크롤 압축기의 급유장치는 하부 프레임의 축방향 지지부인 스러스트 플레이트와 접하는 크랭크 축의 하단 스러스트면에 크랭크 축의 원주면을 따라 다수개의 오일급유홈을 형성하여, 크랭크 축의 스러스트면과 스러스트 플레이트 사이에 오일공급이 원활하게 이루어져, 마찰력 감소로 인한 압축기의 입력이 감소하여 효율이 증대될 뿐만 아니라 금속과 금속의 접촉을 피하게 되어 마모를 방지하도록 하였다.The lubrication device of the scroll compressor according to the present invention forms a plurality of oil lubrication grooves along the circumferential surface of the crank shaft on the lower thrust surface of the crank shaft in contact with the thrust plate, which is an axial support of the lower frame, between the thrust surface and the thrust plate of the crank shaft. The oil supply is smoothly applied, which reduces the input of the compressor due to the reduced frictional force, thereby increasing the efficiency and avoiding contact between the metal and the metal to prevent wear.
