SHAFT-HUB COMPONENT AND METHOD FOR PRODUCING SUCH A COMPONENT

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.
