Rotor disk assembly having a two-part seal

Abstract

A rotor disk assembly having a two-part seal, wherein the rotor disk assembly has a rotor disk, on which a plurality of sealing plates is arranged in front of an end side and wherein a plurality of separate sealing vanes is arranged radially outside of the sealing plates in a circumferentially distributed manner.

1 - 15 . (canceled) 
     
     
         16 . A rotor disk assembly, comprising:
 a rotor disk which has a multiplicity of axially extending blade retention grooves distributed on the outer circumference, and an encompassing plate retention groove, or a plurality of plate retention grooves distributed on the circumference, in front of an end face beneath the blade retention grooves,   a multiplicity of sealing plates which have a flat design and extend transversely to the rotor axis and together form a basically closed ring and are mounted on the respective inner circumference in the plate retention groove and cover the blade retention grooves in certain sections, and   a multiplicity of separate sealing vanes which are arranged in front of the end face adjacent to the outer circumference of the sealing plates and cover the blade retention grooves in certain sections,   wherein the rotor disk has a multiplicity of circumferentially distributed mounting bases, which mounting bases extend axially from the end face beyond the sealing plate, wherein the sealing vanes have at least one fastening socket in which is arranged the mounting base.   
     
     
         17 . The rotor disk assembly as claimed in  claim 16 ,
 wherein the sealing plates are produced in each case from a flat metal sheet; and/or   wherein all the sealing plates are designed as identical parts.   
     
     
         18 . The rotor disk assembly as claimed in  claim 16 ,
 wherein the sealing vanes, in a cross section along the rotor axis, are of a U-shaped or V-shaped radially outward opening design; and/or   all the sealing vanes are designed as identical parts.   
     
     
         19 . The rotor disk assembly as claimed in  claim 16 ,
 wherein the distance of the mounting base to the rotor axis on the end face is greater than on its free end.   
     
     
         20 . The rotor disk assembly as claimed in  claim 16 ,
 wherein the sealing vane has at least two fastening sockets with a free space in between, which free space, with rotation of the sealing vane relative to the rotor disk, enables removal of the sealing vane from the mounting bases in the axial and/or radial direction.   
     
     
         21 . The rotor disk assembly as claimed in  claim 16 ,
 wherein the mounting base has a constant or reducing thickness perpendicularly to the underside of the mounting base, measured from the end face to the free end, and/or the fastening socket, on the side pointing away from the rotor axis, has an adequate free space which enables removal in a direction pointing axially and toward the rotor axis.   
     
     
         22 . The rotor disk assembly as claimed in  claim 21 ,
 wherein at least one sealing vane has lateral edges extending parallel and opposite each other in the circumferential direction.   
     
     
         23 . The rotor disk assembly as claimed in  claim 16 ,
 wherein the sealing vanes, on the side pointing toward the rotor axis, have a support surface against which butts the sealing plates by an outer circumferential surface.   
     
     
         24 . The rotor disk assembly as claimed in  claim 23 ,
 wherein the sealing vanes have a retaining projection, adjacent to the support surface and pointing toward the rotor axis, against which retaining projection butts the sealing plates on the outer circumference opposite the end face.   
     
     
         25 . The rotor disk assembly as claimed in  claim 23 ,
 wherein the sealing plates, with rotation of the rotor disk assembly, are supported against the sealing vanes and by means of their centrifugal force induce torque in the sealing vanes around the free end of the mounting base.   
     
     
         26 . The rotor disk assembly as claimed in  claim 16 , further comprising:
 a locking element which fits through the sealing vane and/or the sealing plate and engages in a recess on the rotor disk or rotor blade or acts against an abutment.   
     
     
         27 . The rotor disk assembly as claimed in  claim 16 , further comprising:
 a locking element fixedly arranged on the rotor blade, raised from the end face, and engages in a recess on the sealing plate and/or on the sealing vane or acts against an abutment.   
     
     
         28 . A rotor comprising:
 a rotor disk assembly as claimed in  claim 16 .   
     
     
         29 . A gas turbine comprising:
 a rotor as claimed in  claim 28 .   
     
     
         30 . The rotor disk assembly as claimed in  claim 16 ,
 wherein the multiplicity of circumferentially distributed mounting bases are arranged between the blade retention grooves in each case.   
     
     
         31 . The rotor disk assembly as claimed in  claim 26 ,
 wherein the locking element fits through two adjacent sealing vanes and/or two adjacent sealing plates and/or sealing vane and sealing plate, at least in certain sections, and engages in a recess on the rotor disk or rotor blade or acts against an abutment.
