Patent ID: 7874791

Claim:
A turbomachine comprising: a rotor having at least one moving blade row with a plurality of moving blades; a stator having at least one guide vane row with a plurality of guide vanes; at least in one of at least one moving blade row and at least one guide vane row, all the blades or vanes each having a shroud plate; a securing device securing each shroud plate to an associated blade or vane axially, circumferentially, or both, against relative adjustment; wherein the shroud plates are separate components from the respective blade or vane and are mounted on the respective blade or vane to be radially movable with respect to said blade or vane; wherein circumferentially adjacent shroud plates are directly coupled to one another for the transmission of tensile forces in the circumferential direction; and wherein the shroud plates are configured and arranged to form a self-supporting annularly closed ring when the turbo machine is rotating; wherein each shroud plate is mounted on an associated blade or vane to be fixed axially, fixed circumferentially with respect to an associated blade or vane, or both; wherein each shroud plate includes a securing orifice and each securing device has at least one securing member which is arranged radially movably on a respective blade or vane; wherein each shroud plate contains, for each securing member, at least one desecuring orifice through which the securing member can be driven out of the securing orifice and into the associated blade or vane.
