The internal rotor member has a frusto-conical outer surface and the fibre-reinforced sleeve is arranged on the outer surface of an internally frusto-conical intermediate sleeve, the conicity of which corresponds to the conicity of the internal rotor member. The intermediate sleeve with the external fibre-reinforced sleeve is pressed on the internal rotor member in the axial direction.
