Title (EN) SEALING ABUTTING CONFIGURATION WITH MICROCOSMIC TOOTHED RINGS
(FR) CONFIGURATION D'ÉTANCHÉITÉ EN BUTÉE AVEC BAGUES DENTÉES MICROCOSMIQUES
(ZH) 微观锯齿环密封对接结构
Abstract:
(EN) A sealing abutting configuration with microcosmic toothed rings is disclosed, and one of the two abutting surfaces is a toothed surface with at least one microcosmic toothed ring, and the other surface is a smooth surface; the tooth crests of the toothed rings are bladed; the blade tip angle or the addendum angle is about 90°~120°; the tooth depth Zt is about 10~20 times of the seal surface roughness Ra; the tooth pitch Xs / the tooth depth Zt is about 20~500. This can ensure the abutting contact is the line contact in the surface following behind the microcosmic line, and not only the necessary stress of the sealing is easily provided but also the contact line is effectively protected against breakage.
(FR) L'invention concerne une configuration avec des bagues dentées microcosmiques, l'une des deux surfaces en butée étant une surface dentée avec au moins une bague dentée microcosmique, l'autre surface étant une surface lisse. Les crêtes des dents des bagues dentées sont dotées de lames. L'angle de l'extrémité de la lame ou l'angle de saillie est d'environ 90° à 120°. La profondeur de la dent Zt est d'environ 10 à 20 fois la rugosité Ra de la surface du joint ; le pas des dents Xs / la profondeur des dents Zt est d'environ 20 à 500. Cela permet de garantir que le contact en butée est le contact linéaire dans la surface derrière la ligne microcosmique. De plus, non seulement la contrainte nécessaire du joint est facilement assurée, mais la ligne de contact est également efficacement protégée contre la rupture.
