  • Assembled rotor shaft with an asymmetrical design, rotor, and method for producing the assembled rotor shaft and rotor
    Patent number: 11056940
    Abstract: An assembled rotor shaft of asymmetrical design may comprise two rotor shaft components, a first rotor shaft component configured as a shaft segment with a tube section and a flange section, and a second rotor shaft component configured as a flange element. The tube section may include a tube outer surface with a profiling. A rotor of an electric machine, which includes the assembled rotor shaft, may further include a laminated core and a pressure disk disposed in the tube section. The laminated core can include laminated core disks, each of which has a structuring that corresponds to the profiling of the rotor shaft. The profiling and the structuring of the laminated core disks may form a positively locking connection.
