PROBLEM TO BE SOLVED: To eliminate the need for time-consuming and costly rotor disassembly and reassembly required if unbalance causes a machine to shut down due to unacceptable vibrations.SOLUTION: A torque transmission mechanism for a gas turbine rotor includes a plurality of adjacent rotating wheels 2. Each wheel includes a first flange on a first axial side and a second flange on a second axial side. The first flange has a plurality of first teeth extending around the circumference of the first flange and spaced by first slots, and the second flange has a plurality of second teeth extending around a circumference of the second flange and spaced by second slots. The first teeth of a first wheel are received in the second slots of a second adjacent wheel to transmit torque through shear of the teeth and the first flange and the second flange are engaged to transmit torque through friction between the flanges.
