US Patent 11060563 Shaft-hub connection

A shaft-hub connection includes a shaft, which is provided with an external toothing arrangement in a connecting region. The shaft-hub connection also includes a hub, which is provided with an internal toothing arrangement in a connecting region. The external toothing arrangement has a first tip diameter (K1) on the side facing the axial end of the shaft and a second, larger tip diameter (K2) on the side of the connecting region facing away from the axial end so that together with the internal toothing arrangement of the hub a clearance fit is created in the region of the first tip diameter (K1) and an interference fit is created in the region of the second tip diameter (K2).
