Patent ID: 8573943

Claim:
A turbine rotor, comprising: a plurality of rotor blades which are combined in each case to form rotor blade rows and are arranged on in each case one turbine disk, the turbine disk, comprising: a plurality of sealing plates, on side faces of the turbine disk, in a shape of circularly annular sections which are inserted into an azimuthally extending turbine disk groove, wherein the respective sealing plate includes, on a side which faces a turbine axle, an azimuthally extending edge which is spaced apart from an inner edge of the respective sealing plate, and a closure piece arranged between the edge of the respective sealing plate and a side wall of the turbine disk groove, wherein the edge extends over the entire azimuthal length of the sealing plate and the closure pieces bear against one another in an azimuthal direction for sealing purposes, and wherein the respective sealing plate comprises a recess which extends substantially azimuthally on the side which faces the turbine axle, interrupts the respective edge and is designed geometrically in such a way that the closure pieces are inserted into the turbine disk groove through the recess.
