Title
(EN) WHEEL DISK ASSEMBLY HAVING SIMPLIFIED SEALING-PLATE MOUNTING
Abstract
(EN)

A wheel disk assembly, having a wheel disk, a plurality of blade devices, which are fastened along the outer circumference of the wheel disk, and a plurality of sealing plates, which are retained in two annular grooves radially spaced apart from each other. A first annular groove is in the wheel disk and a second annular groove is formed by the blade devices in a segmented manner. Simplified mounting of the sealing plates is achieved in that the first annular groove is expanded by an axially extending recess.
