Abstract (en)
[origin: WO2016008791A1] Wheel disc arrangement (1) comprising a wheel disc (2), a plurality of blade devices (3) which are fastened along the outer circumference of the wheel disc (2), and a plurality of sealing plates (4) which are held in two radially spaced-apart annular grooves (5, 6), wherein the first annular groove (5) is provided in the wheel disc (2) and is bounded axially outwards by an annular projection (7), and wherein the second annular groove (6) is defined by a plurality of adjacently arranged annular groove segments which are each provided in the individual blade devices (3), wherein the first annular groove (5) is of undercut design and, as viewed in cross section, has at least two axially opposite and protruding holding projections (10) which are provided with a respective bearing surface (11), and wherein, as viewed in cross section, the sealing plates (4) have, in the region of the inside diameter, two supporting projections (12) corresponding to the holding projections (10), which supporting projections are axially opposite one another and face away from one another and are each provided with a supporting surface (13), wherein the bearing surfaces (11) of the holding projections (10), the supporting surfaces (13) of the supporting projections (12) and the height of the sealing plates (4) are configured in such a way that, during the intended operation of the wheel disc arrangement (1), the supporting surfaces (13) of the sealing plates (4) are supported against the bearing surfaces (11) of the holding projections (10) under the effect of a centrifugal force.
