In the case of a rotor ( 10 ) having a rotor spider ( 11 ), which is mounted such as it can rotate about an axis ( 15 ) and has two or more ribs ( 12 ), and having a laminated rim ( 14 ), which concentrically surrounds the rotor spider ( 11 ) and is composed of individual rim laminates ( 16 ), and which is connected to the rotor spider ( 11 ) by means of wedges ( 13 ) via a laminated rim wedge system, a simplified connection between the laminated rim ( 14 ) and the rotor spider ( 11 ) is achieved in that the wedges ( 13 ) and the rim laminates ( 16 ) are designed such that they engage in one another in an interlocking manner, forming a rigid connection.
1. A rotor comprising:
a rotor spider mounted to rotate about an axis, the rotor spider including at least two ribs;
a laminated rim which concentrically surrounds the rotor spider and comprises individual rim laminates;
a laminated rim wedge system including wedges;
wherein the laminated rim is connected to the rotor spider by the wedges of the laminated rim wedge system;
wherein the wedges and the rim laminates are configured and arranged to interlockingly engage in one another and to form a rigid connection; and
wherein the wedges comprise dovetails on a side facing the laminated rim, and wherein the rim laminates comprise cutouts in which said dovetails engage to form a rigid connection.
2. The rotor as claimed in claim 1 , wherein the rim laminates each have at least two cutouts, and wherein each of the cutouts is bounded on one side by a contact flank comprising a dovetail and on the other side by a flank arranged at right angles.
3. The rotor as claimed in claim 2 , wherein the dovetail contact flanks are arranged on the same side in the cutouts in the rim laminates and the rim laminates in the laminated rim are arranged in a mutually laminated form and alternatingly reversed in layers on top of one another.
4. The rotor as claimed in claim 2 , wherein the dovetail contact flanks are arranged on alternate sides in the cutouts in the rim laminates, and the rim laminates are arranged in a mutually laminated form in layers on top of one another in the laminated rim.
5. The rotor as claimed in claim 1 , wherein the rotor spider comprises oblique ribs, and the wedges are firmly connected to the oblique ribs.
6. The rotor as claimed in claim 1 , wherein the rotor spider comprises radial ribs, and further comprising:
wedge supports attached to the radial ribs; and
wherein the wedges are slidingly mounted in the wedge supports.
7. The rotor as claimed in claim 5 , wherein the wedges are welded to the ribs.
