Title
(DE) ROTORSCHEIBE MIT STIRNSEITIGEM DICHTELEMENT
(EN) ROTOR DISK HAVING AN END-FACE SEALING ELEMENT
(FR) DISQUE DE ROTOR MUNI D’UN ÉLÉMENT D‘ÉTANCHÉITÉ CÔTÉ FRONTAL
Abstract
(DE)
Die Erfindung betrifft eine Abdichtung an einer Rotorscheibenanordnung mit einer Rotorscheibe (01), welche (01) am Außenumfang verteilt eine Mehrzahl axial verlaufender Schaufelhaltenuten (09) aufweist. Weiterhin umfasst die Rotorscheibenanordnung eine Mehrzahl im Umfang verteilt angeordneter Dichtelemente (11), welche (11) die Schaufelhaltenuten (09) stirnseitig zumindest abschnittsweise abdecken. Hierbei sind die Dichtelemente (11) auf der zur Rotorachse weisenden Seite mit einem Befestigungsabschnitt (13) an einem Befestigungsvorsprung (03) der Rotorscheibe (01) gelagert.
(EN)
The invention relates to a seal on a rotor disk assembly having a rotor disk (01), which rotor disk (01) has a plurality of axially extending blade-retaining grooves (09) distributed on the outer periphery. Furthermore, the rotor disk assembly comprises a plurality of sealing elements (11) distributed over the periphery, which sealing elements (11) cover the blade-retaining grooves (09) at the associated end face at least in some sections. The sealing elements (11) are supported on the side facing the rotor axis on a fastening protrusion (03) of the rotor disk (01) by means of a fastening section (13).
(FR)
L’invention concerne un joint d’étanchéité d’un système de disque de rotor muni d’un disque de rotor (01) qui présente une pluralité de rainures de retenue d’aube (09) s’étendant axialement et réparties sur la circonférence extérieure. Le système de disque de rotor comprend par ailleurs une pluralité d’éléments d’étanchéité (11) répartis sur la circonférence, lesquels éléments d’étanchéité (11) recouvrent les rainures de retenue d’aube (09) au moins par endroits côté frontal. Les éléments d’étanchéité (11) sont montés sur le côté faisant face à l’axe du rotor par une section de fixation (13) sur une partie saillante de fixation (03) du disque de rotor (01).
