Patent ID: 8646181

Claim:
Method for manufacturing a shaft-hub component having a shaft, a hub component and a shaft-hub connection for an armature of an electrical machine, comprising the steps: hardening a surface layer of the shaft, wherein the surface layer of the shaft has a thickness from about 0.01 mm to about 0.1 mm, and wherein the hardening of the surface layer results in a hardness of 200 to 500 HV (hardness according to Vickers), shaping of the shaft such that a partial region of said shaft is shaped in such a manner that at least a radially projecting section and a radially indented section are produced, and wherein the radially indented sections are indented further than the thickness of the surface layer, and joining of the shaped shaft and the hub component to the shaft-hub component so that the shaft-hub connection includes an interference fit on the projecting section, a hardness of said hub component being less than a surface layer hardness of said shaft.
