Abstract: A steam turbine system including a steam turbine which has a turbine housing and at least one turbine shaft accommodated in the turbine housing and sealed by seals, a condenser connected fluidically to the steam turbine, an evacuation unit connected fluidically to the condenser, and a dry air source which is connected fluidically to the steam turbine, wherein the steam turbine system is designed in such a way that the evacuation unit is optionally fluidically connectable to the dry air source. A method for preserving components of a steam turbine system to prevent idle-state corrosion is also provided, which the steps: shutting down a steam turbine of the steam turbine system and sucking dry air into the steam turbine using an evacuation unit which additionally functions during intended operation of the steam turbine to exhaust a resulting amount of gas into a condenser.

Abstract: 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.

Abstract: Wheel disc arrangement has a wheel disc, a plurality of blade devices fastened along the outer circumference, and a plurality of sealing plates held in two radially spaced-apart annular grooves. The first annular groove is bounded axially outwards by an annular projection. The second annular groove is defined by a plurality of adjacently arranged annular groove segments in the individual blade devices. The first annular groove is of undercut design and has at least two axially opposite and protruding holding projections with a respective bearing surface. The sealing plates have, in the inside diameter, two supporting projections corresponding to the holding projections, axially opposite and face away from one another, with a supporting surface. The arrangement is configured such that the supporting surfaces of the sealing plates are supported against the bearing surfaces of the holding projections under the effect of a centrifugal force.

Abstract: A component, provided with a thread has increased play in the axial direction in comparison with a standard thread, which allows nuts to be screwed on, even in the case of highly preloaded bolts, and also enables a highly loadable threaded connection. For this purpose, the play is monotonically increasing in the axial direction.

Abstract: 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, the first annular groove in the wheel disk and bounded axially outward by an annular projection, and the second annular groove defined by a plurality of annular-groove segments arranged adjacently, which are in the individual blade devices. At least one opening extends axially through the annular projection, the minimum width of which opening in the circumferential direction is greater than the width of the sealing plates at the inside diameter such that a sealing plate is axially insertable between the annular grooves through the opening and moveable in the circumferential direction while guided by the annular grooves. A method assembles such a wheel disk assembly.

Abstract: A wheel disk assembly having a wheel disk, a plurality of blade devices, which are arranged thereon in a manner distributed over the circumference, and a plurality of sealing plates, which are retained in two annular grooves spaced apart from each other radially. In this assembly, the first annular groove is provided in the wheel disk and is bounded axially outward by an annular projection. The projection, in turn, is interrupted by a recess extending in the circumferential direction, with the result that a sealing plate can be inserted axially through the recess between the annular grooves. A closure piece is furthermore provided for closing the recess, which closure piece is captively retained on the sealing plate by a form fit.
