Abstract:
(EN) A bush bearing having an outer lubricating layer, a manufacturing method therefor and a scroll compressor having same applied thereto, according to the present invention, includes a bush bearing comprising: a base member which has a cylindrical shape having no separated surfaces along the circumferential direction; and a lubricating member which is formed from a material having a lower rigidity and more excellent lubricity than the base member, and has a cylindrical shape having no separated surfaces along the circumferential direction by being integrally provided to the outer circumferential surface of the base member, wherein the cylindricity of the outer circumferential surface of the lubricating member is formed so as to satisfy having a value that is within 0.6% of the average thickness of the lubricating member, and the lubricating member has carbon fiber contained in a resin base, wherein the carbon fiber has cut surfaces exposed on both ends of the lubricating member.
(FR) La présente invention concerne un palier lisse ayant une couche de lubrification externe, son procédé de fabrication et un compresseur à spirale correspondant, le palier lisse comprenant : un élément de base de forme cylindrique qui n'a pas de surfaces séparées le long de la direction circonférentielle; et un élément de lubrification qui est constitué d'un matériau ayant une rigidité inférieure et un pouvoir lubrifiant encore meilleurs que ceux de l'élément de base, et qui se présente sous une forme cylindrique qui n'a pas de surfaces séparées le long de la direction circonférentielle du fait de sa disposition d'un seul tenant sur la surface circonférentielle externe de l'élément de base. La forme cylindrique de la surface circonférentielle externe de l'élément de lubrification est formée de manière à satisfaire une valeur qui se situe à 0,6 % de l'épaisseur moyenne de l'élément de lubrification, et l'élément de lubrification comprend une fibre de carbone contenue dans une base en résine, la fibre de carbone ayant des surfaces coupées apparentes sur les deux extrémités de l'élément de lubrification.
(KO) 본 발명에 의한 외부윤활층을 가지는 부시 베어링 및 그의 제조 방법 및 이를 적용한 스크롤 압축기는, 원주방향을 따라 이격면이 없는 원통 형상으로 형성되는 베이스 부재; 및 상기 베이스 부재에 비해 강성은 낮고 윤활성은 우수한 소재로 이루어지고, 상기 베이스 부재의 외주면에 일체로 구비되어 원주방향을 따라 이격면이 없는 원통 형상으로 형성되는 윤활 부재;를 포함하고, 상기 윤활 부재의 외주면 원통도(cylindricty)가 상기 윤활 부재의 평균두께 대비 0.6% 이내를 만족하도록 형성되며, 상기 윤활 부재는 수지 계열에 탄소 섬유가 함유되고, 상기 탄소 섬유는 상기 윤활 부재의 양단에 절단면이 노출되는 부시 베어링을 포함한다.
