Abstract
(EN) Provided is a sliding component that can stably reduce friction resistance between sliding surfaces in conjunction with eccentric rotation. This sliding component 7 has a sliding surface 7a that is formed in a circular shape and undergoes relative sliding in conjunction with eccentric rotation. The sliding surface 7a is provided with a dynamic pressure generation groove 70 that is formed in a circular shape along the sliding surface 7a, and a plurality of communication grooves 71 enabling communication between the dynamic pressure generation groove 70 and a space 50 on the outside of the sliding surface 7a, and the communication grooves 71 are arranged in a relationship such that a hypothetical line LN passing through a center point Q of the sliding surface 7a and one communication groove 71A does not intersect other communication grooves 71B-71C.
(FR) Un composant coulissant qui est apte à réduire la résistance de frottement entre des surfaces coulissantes en conjonction avec une rotation excentrique est divulgué. Ce composant coulissant 7 a une surface de glissement 7a qui est formée sous une forme circulaire et subit un glissement relatif en conjonction avec une rotation excentrique. La surface coulissante 7a est pourvue d'une rainure de génération de pression dynamique 70 qui est formée selon une forme circulaire le long de la surface coulissante 7a, et une pluralité de rainures de communication 71 permettant la communication entre la rainure de génération de pression dynamique 70 et un espace 50 sur l'extérieur de la surface de coulissement 7a, et les rainures de communication 71 sont agencées dans une relation telle qu'une ligne hypothétique LN passant par un point central Q de la surface coulissante 7a et une rainure de communication 71A ne croise pas d'autres rainures de communication 71B-71C.
(JA) 偏心回転を伴う摺動面間の摩擦抵抗を安定して低減することができる摺動部品を提供する。 円環形状を成し、偏心回転を伴って相対摺動する摺動面7aを有する摺動部品7であって、摺動面7aは、摺動面7aに沿って円環状を成す動圧発生溝70と、動圧発生溝70と摺動面7aの外部空間50とを連通する複数の導通溝71と、を備え、導通溝71は、一の導通溝71Aと摺動面7aの中心点Qとを通る仮想線LN上に他の導通溝71B~71Cが交わらない配置関係となっている。
