Abstract
A camshaft and method of producing a camshaft for an internal combustion engine. The camshaft includes a base shaft and an external toothing extending at least in certain portions axially along the base shaft. The camshaft includes a hub with an internal toothing which correlates with the external toothing of the base shaft such that the hub is connected rotationally conjointly and axially non-displaceably to the base shaft. The external toothing has at least one form-fit subregion that extends axially at least in certain portions along the base shaft, or one force-fit subregion in order for the hub to be arranged at least in a form-fitting or force-fitting manner. At least the form-fit subregion or the force-fit subregion is adjoined by at least one alignment region which extends at least in certain portions axially along the base shaft and which serves for the angular alignment of the hub.
