WHEEL DISK ASSEMBLY

摘要

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 (4), which are retained in two annular grooves (5, 6) spaced apart from each other radially, wherein the first annular groove (5) is provided in the wheel disk (2) and is bounded axially outward 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 provided in the individual blade devices (3), wherein at least one recess (8) extending axially through the annular projection (7) is provided, the minimum width of which recess in the circumferential direction is greater than the width of the sealing plates (4) at the inside diameter such that a sealing plate (4) can be inserted between the annular grooves (5, 6) axially through the recess (8) and can be moved in the circumferential direction in such a way that said sealing plate is guided by the annular grooves, and that at least one closure piece (9) is provided, which is prepared for closing the recess (8) and which can be detachably fastened to the wheel disk (2), wherein the closure piece (9), when mounted as intended, is captively retained in the axial direction by a form fit provided between the closure piece (9) and at least one sealing plate (4).
