Abstract:
(EN) Provided are a segment, a combined oil ring, and a segment manufacturing method, with which independent rotation of the segments can be prevented while accommodating lower tensile force in the combined oil ring. The inner-circumferential surfaces 22, 32 of segments 20, 30 are pressed by an ear part 43 formed in the circumferential direction of an expander-spacer 40, and the segments are able to slide in the axial direction of a cylinder 1 while the outer-circumferential side of the segments is pressed against an inner wall of the cylinder 1. Dross-like protrusions 26, 36 are provided in at least two locations in the circumferential direction on the inner-circumferential surfaces 22, 32 of the segments 20, 30, and the dross-like protrusions 26, 36 protrude to a height of 4–25 μm.
(FR) L'invention concerne un segment, un anneau d'huile combiné et un procédé de fabrication de segment, avec lesquels une rotation indépendante des segments peut être empêchée tout en recevant une force de traction inférieure dans l'anneau d'huile combiné. Les surfaces circonférentielles internes (22, 32) des segments (20, 30) sont pressées par une partie ergot (43) formée dans la direction circonférentielle d'un écarteur-espaceur (40), et les segments sont aptes à coulisser dans la direction axiale d'un cylindre (1) tandis que le côté circonférentiel externe des segments est pressé contre une paroi interne du cylindre (1). Des saillies de type écume (26, 36) sont disposées en au moins deux emplacements dans la direction circonférentielle sur les surfaces circonférentielles internes (22, 32) des segments (20, 30), et les saillies de type écume (26, 36) font saillie à une hauteur de 4 à 25 µm.
(JA) 組合せオイルリングの低張力化に対応させつつも、セグメントの単独回転を防止することが可能なセグメント、組合せオイルリングおよびセグメントの製造方法を提供する。 エキスパンダ・スペーサ40の周方向に形成されている耳部43によって内周面22,32が押圧されると共に外周側がシリンダ1の内壁に押圧された状態で該シリンダ1の軸方向に摺動可能なセグメント20,30であって、セグメント20,30の内周面22,32には、ドロス状突出部26,36が周方向において少なくとも2箇所以上設けられていて、そのドロス状突出部26,36は、4μm~25μmの突出高さに設けられている。
