Abstract

Une rainure est appliquée à une ou plusieurs surfaces de contact d’un palier lisse d’une pompe pour augmenter une force appliquée à la ou aux surfaces de contact. Chaque rainure présente une extrémité exposée à la pression de refoulement de la pompe de sorte que la rainure communique la pression de refoulement sur la surface de contact. La rainure réduit une aire de la surface de contact sur laquelle une fuite de fluide se traduit par un différentiel de pression, augmentant ainsi une force nette appliquée à la surface de contact. L’application de la rainure sur la face d’extrémité axiale du palier lisse améliore une force axiale appliquée au palier lisse tandis que l’application de la rainure à un cordon orienté radialement réduit les frottements entre le palier lisse et le corps externe. Figure pour l’abrégé : Fig. 8.
