Title
(EN) Wheel disk assembly having simplified sealing-plate mounting
(ZH) 具有简化的密封板安装的轮盘组件
Abstract
(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).
