Title
(DE) RADSCHEIBENANORDNUNG MIT VEREINFACHTER DICHTBLECHMONTAGE
(EN) WHEEL DISK ASSEMBLY HAVING SIMPLIFIED SEALING-PLATE MOUNTING

Abstract
(DE)
Die Erfindung betrifft eine Radscheibenanordnung (1) mit einer Radscheibe (2), mehreren Schaufeleinrichtungen (3), die entlang des Außenumfangs der Radscheibe (2) befestigt sind, und mehreren Dichtblechen (5), die in zwei radial voneinander beabstandeten Ringnuten (6, 7) gehalten sind. Eine erste Ringnut (6) ist in der Radscheibe (2) und eine zweite Ringnut wird segmentiert von den Schaufeleinrichtungen (3) gebildet. Eine vereinfache Montage der Dichtbleche wird erzielt, indem die erste Ringnut (6) um eine sich axial erstreckende Vertiefung (13) erweitert wird.
(EN)
The invention relates to a wheel disk assembly (1), comprising a wheel disk (2), a plurality of blade devices (3), which are fastened along the outer circumference of the wheel disk (2), and a plurality of sealing plates (5), which are retained in two annular grooves (6, 7) radially spaced apart from each other. A first annular groove (6) is in the wheel disk (2) and a second annular groove is formed by the blade devices (3) in a segmented manner. Simplified mounting of the sealing plates is achieved in that the first annular groove (6) is expanded by an axially extending recess (13).
(FR)
La présente invention concerne un ensemble disque de roue (1) comportant un disque de roue (2), plusieurs aubes (3) fixées sur la périphérie externe du disque de roue (2) et plusieurs tôles d'étanchéité (5), qui sont retenues dans deux rainures annulaires (6, 7) radialement espacées l'une de l'autre. Une première rainure annulaire (6) est ménagée dans le disque de roue (2) et une seconde rainure annulaire est formée de manière segmentée par les aubes (3) Le montage des tôles d'étanchéité est simplifié du fait que la première rainure annulaire (6) est élargie par un renfoncement (13) qui s'étend axialement (13).
