Abstract: front page image
(EN)Disclosed is a hydrostatic piston bearing of a single rod cylinder which comprises: a housing including a chamber and a rod guide; a piston housed in the housing and partitioning the chamber into a front chamber and a rear chamber by means of a head formed on the rear end of the rod; an inlet tube passing through one side of the housing in order for the outside of the housing to be in communication with the rear chamber; and an outlet tube passing through the other side of the housing in order for the outside of the housing to be in communication with the front chamber. The hydrostatic piston bearing of a single rod cylinder comprises: a plurality of first pockets formed on the outer periphery in the circumferential direction of the head; a plurality of second pockets formed on the inner periphery in the circumferential direction of the rod guide; a first supply tube defining a conduit line in the head and in communication with the rear chamber with the first pockets; and a second supply tube defining a conduit line in the housing and in communication with the inlet tube with the second pockets, wherein a hydrostatic bearing is formed in the first pockets and the second pockets by means of a fluid supplied through the first supply tube and the second supply tube, and there is no need to install a separate fluid supply and discharge line at the outside of the cylinder to form a hydrostatic bearing.
(FR)L'invention concerne un palier de piston hydrostatique de vérin à simple tige qui comprend : un corps comprenant une chambre et un guide-tige ; un piston logé dans le corps et divisant la chambre en une chambre avant et une chambre arrière au moyen d'une tête formée sur l'extrémité arrière de la tige ; un tube d'admission traversant un côté du corps afin que l'extérieur du corps communique avec la chambre arrière ; et un tube d'évacuation traversant l'autre côté du corps afin que l'extérieur du corps communique avec la chambre avant. Le palier de piston hydrostatique de vérin à simple tige comprend : une pluralité de premières poches formées sur la périphérie externe dans le sens circonférentiel de la tête ; une pluralité de secondes poches formées sur la périphérie interne dans le sens circonférentiel du guide-tige ; un premier tube d'alimentation formant une tubulure dans la tête et communiquant avec la chambre arrière par les premières poches ; et une second tube d'alimentation formant une tubulure dans le corps et communiquant avec le tube d'admission par les secondes poches, un palier hydrostatique étant formé dans les premières et les secondes poches au moyen d'un fluide acheminé par le premier et le second tube d'alimentation. Il n'est pas nécessaire d'installer une alimentation de fluide et une conduite d'évacuation distinctes à l'extérieur du vérin pour former un palier hydrostatique.
(KO)챔버 및 로드가이드를 포함하는 하우징과, 상기 하우징에 수용되어 로드의 후단부에 형성되는 헤드에 의해 상기 챔버를 전측챔버와 후측챔버로 구획하는 피스톤과, 상기 하우징의 일측을 관통하여 상기 하우징의 외부와 상기 후측챔버를 연통시키는 유입관 및, 상기 하우징의 타측을 관통하여 상기 하우징의 외부와 상기 전측챔버를 연통시키는 토출관을 포함하는 편 로드 실린더에 있어서, 상기 헤드의 원주방향을 따라 외주면에 복수로 형성되는 제1 포켓 및, 상기 로드가이드의 원주방향을 따라 내주면에 복수로 형성되는 제2 포켓과, 상기 헤드의 내부에 관로를 형성하여 상기 후측챔버와 제1 포켓을 연통시키는 제1 공급관 및, 상기 하우징의 내부에 관로를 형성하여 상기 유입관과 제2 포켓을 연통시키는 제2 공급관을 포함하여, 상기 제1 공급관과 제2 공급관을 통하여 공급되는 유체에 의해 상기 제1 포켓과 제2 포켓에 정압베어링이 형성되는 것을 특징으로 하여, 정압베어링을 형성하기 위한 별도의 유체 공급 및 토출 라인을 실린더의 외부에 설치할 필요가 없는 편 로드 실린더의 피스톤 정압베어링에 관한 것이다.
