Abstract:
(EN) [Problem] To provide a sliding component with which the performance of a plurality of dimples formed on a sliding surface can be sufficiently exploited, thus improving lubrication performance and sealing performance. [Solution] Provided is a pair of sliding components having respective sliding surfaces S that slide relative to each other, wherein at least one of the sliding surfaces S is equipped with a plurality of dimples 10, and the dimples 10 comprise a recessed portion 15 and a peripheral edge portion 11 that is shallower than the recessed portion 15 and is located at the outer perimeter of the recessed portion 15.
(FR) Le problème décrit par la présente invention est de fournir un composant coulissant avec lequel les performances d'une pluralité d'alvéoles formées sur une surface coulissante peuvent être suffisamment exploitées, améliorant ainsi les performances de lubrification et les performances d'étanchéité. La solution selon l'invention porte sur une paire de composants coulissants ayant des surfaces coulissantes respectives S qui coulissent les unes par rapport aux autres, au moins l'une des surfaces coulissantes S étant équipée d'une pluralité d'alvéoles 10, et les alvéoles 10 comprenant une partie évidée 15 et une partie bord périphérique 11 qui est moins profonde que la partie évidée 15 et qui est située au niveau du périmètre externe de la partie évidée 15.
(JA) 【課題】摺動面に形成された複数のディンプルの性能を十分に引き出すことができ、延いては潤滑性能及び密封性能を向上させた摺動部品を提供することを目標とする。 【解決手段】互いに相対摺動する摺動面Sを有する一対の摺動部品であって、少なくとも一方側の摺動面Sは、複数のディンプル10を備え、ディンプル10は、凹部15と、凹部15の外周部に、かつ、凹部15より浅い周縁部11と、を備える。
