Field of the Invention The present invention relates to a method for surface treatment of an old damling surface of a scroll compressor. The present invention relates to a method for surface treatment of a scroll compressor, in which an aluminum nitride film is formed on a sliding part of the old daming ring to increase the reliability of the compressor.
일반적인 스크롤 압축기는 도 1에 도시한 바와 같이, 밀폐용기(10)의 내주면 메인베어링(5) 및 로우베어링(2)이 용접으로 고정되고, 그 베어링(5)(2)의 사이에 고정자(4)가 고정 설치되며, 그 고정자(4)의 내주면에는 회전자(6)가 삽입 설치되고, 그 회전자(6)의 중앙에는 내부에 급유로(1a)가 형성된 구동축(1)이 메인베어링(5)의 중앙부를 관통하도록 압입되며, 상기 메인베어링(5) 상단면에는 인벌류트 곡선으로 랩이 형성된 선회스크롤(8)이 구동축(1)과 편심되게 결합되어 얹혀지고, 그 선회스크롤(8)의 상측에는 선회스크롤(8)의 랩과 서로 맞물려 압축실을 형성하는 고정스크롤(9)이 얹혀져 메인베어링(5)의 가장자리에 체결되며, 상기 메인베어링(5)과 선회스크롤(8)의 사이에는 자전방지기구인 올담링(11)이 형합되어 있다.In a typical scroll compressor, as shown in FIG. 1, the inner bearing main bearing 5 and the low bearing 2 of the sealed container 10 are fixed by welding, and the stator 4 is disposed between the bearings 5 and 2. ) Is fixedly installed, the rotor 6 is inserted into the inner circumferential surface of the stator (4), the drive shaft (1) in which the oil supply passage (1a) is formed in the center of the rotor (6) is the main bearing ( 5) It is press-fitted to penetrate through the center portion of the main bearing (5), the swinging scroll (8) having a wrap in the involute curve is mounted on the top surface of the main bearing (5) eccentrically coupled, the swinging scroll (8) The upper side of the fixed scroll (9) is engaged with the wrap of the swinging scroll (8) to form a compression chamber is fastened to the edge of the main bearing (5), between the main bearing (5) and the swinging scroll (8) The old dam ring 11 which is a rotation prevention mechanism is integrated.
상기와 같이 구성된 스크롤 압축기는 먼저 인가된 전원에 의해 고정자(4)의 내측에서 회전자(6)가 회전하면서 구동축(1)을 회전시키고 그 구동축(1)은 선회스크롤(8)을 편심거리만큼 편심회전을 시키게 되는데, 이때 상기 올담링(11)에 의해 선회스크롤(8)은 축중심을 원점으로 선회반경만큼 떨어진 거리에서 선회운동을 하게 된다. 이와 같은 선회스크롤(8)의 선회운동에 의해 그 선회스크롤(8)과 고정스크롤(9)의 각 랩 사이에는 압축실이 형성되고, 그 압축실은 지속적인 선회운동에 의해 중심으로 이동하면서 체적이 감소되어 흡입된 냉매가스를 압축하게 되는 것이다.The scroll compressor configured as described above rotates the drive shaft 1 while the rotor 6 rotates inside the stator 4 by an applied power source, and the drive shaft 1 rotates the turning scroll 8 by an eccentric distance. The eccentric rotation is to be made, in which the turning scroll 8 is rotated at a distance separated by the turning radius from the axial center as the origin. By the turning motion of the turning scroll 8, a compression chamber is formed between each turning of the turning scroll 8 and the fixed scroll 9, and the compression chamber is moved to the center by the continuous turning movement and the volume decreases. It is to compress the sucked refrigerant gas.
종래의 압축기에서는 올담링의 규소함량이 약 10% 인 다이캐스팅으로 제조되어 습동부분인 선회스크롤 접촉부(11a)와 메인베어링 접촉부(11b)만 가공되어 사용되어져 왔다. 그러나, 최근 대체 냉매의 등장과 압축기의 고속화에 의해 극심한 운전조건에서 구동됨에 따라 올담링(11)의 습동부분(11a)(11b)의 마모가 증가하는 문제점이 있다.In the conventional compressor, the die-casting having about 10% of the silicon content of the Olddam ring has been used since only the sliding scroll contact portion 11a and the main bearing contact portion 11b, which are sliding parts, have been processed. However, there is a problem in that wear of the sliding portions 11a and 11b of the Oldham ring 11 increases as it is driven under extreme operating conditions due to the recent emergence of replacement refrigerant and high speed of the compressor.
따라서 본 발명의 목적은 상기와 같은 문제점을 고려하여 안출한 것으로, 압축기 올담링의 습동부 표면에 질화알루미늄 피막을 형성하므로 압축기의 신뢰성저하를 방지하도록 한 스크롤 압축기의 올담링표면처리방법을 제공함에 있다.Accordingly, an object of the present invention is to conceive in view of the above problems, and to provide an aluminum nitride film on the sliding part surface of the compressor Old Damling to provide a method for surface treatment of the scroll compressor to prevent degradation of the compressor. have.
