Shaft hub component producing method for armature of electrical machine of vehicle, involves joining shaft and hub components to shaft component, where hardness of hub components is smaller than layer hardness of shaft

摘要

The method involves hardening an edge layer (20) at an outer casing (6) of a shaft (2). Portions of the shaft are shaped such that a radially projecting region (4) and a radially compressed region (5) are produced. The shaped shaft and hub components are joined to a shaft-hub component so that a shaft hub connection has a press fit at the projecting region, where hardness of the hub components is smaller than edge layer hardness of the shaft. An independent claim is also included for a shaft hub component for an armature of an electrical machine.
