Title: SHAFT-HUB CONNECTION AND METHOD FOR CREATING A SHAFT-HUB CONNECTION
Abstract:
The present invention relates to a method for creating a shaft-hub connection (20) and to a shaft-hub connection, comprising a shaft (1) having a round or non-round outer diameter, wherein the method comprises at least the following steps: • a) arranging the shaft (1) in a machining system (50) to machine an exterior surface (6) of the shaft (1) at least in a seat region (4), • b) generating at least one material expansion extending at least in sections in the circumferential direction and in the axial direction in the seat region of the shaft, wherein the material expansion (5) stays the same or runs conically along the shaft longitudinal axis in the axial direction, • c) connecting the hub (10) and shaft (1) such that in the seat region (4) a press connection is created between the shaft (1) and the hub (10). The invention also relates to a machining system (50) for machining an exterior surface (6) of the shaft at least in a seat region (4) to create the shaft-hub connection (20).
