Method for producing a built camshaft

A method for producing an assembled camshaft, comprising the steps of:

• providing a camshaft main body having a longitudinal axis, the camshaft main body including:
• a first axial section having a smooth cylindrical outer profile and an outer diameter d1,
• a second axial section disposed between the first axial section and a third axial section, the second axial section including a toothing extending in an axial direction, wherein the second axial section via the toothing defines a tip circle diameter dK and a root circle diameter dF,
• the third axial section having a smooth cylindrical outer profile and an outer diameter d3,
• wherein d1<dF and d3<dF,
• thermally joining at least one receiving element to the first axial section in a predefined angular and axial position,
• pushing at least one sliding cam onto the second axial section in a predefined angular position,
• thermally joining at least one other receiving element to the third axial section in a predefined angular and axial position, and
• joining a drive wheel to a free end of the first axial section.

An assembled camshaft, comprising:

• a camshaft main body having a longitudinal axis and including:
• a first axial section having a smooth cylindrical outer profile and an outer diameter d1;
• a second axial section disposed between the first axial section and a third axial section, the second axial section having an outer profile including a toothing extending in an axial direction, wherein the second axial section via the toothing defines a tip circle diameter dK and a root circle diameter dF;
• the third axial section having a smooth cylindrical outer profile and an outer diameter d3;
• a drive wheel coupled to a free end of the first axial section;
• at least one receiving element arranged rotationally and axially fixed on the camshaft main body, the at least one receiving element disposed on at least one of the first axial section and the third axial section;
• and
• at least one sliding cam arranged rotationally fixed and axially displaceable on the second axial section;
• wherein the at least one receiving element is thermally joined to the camshaft main body and defines at least one of a form fit connection and a shrink fit connection.
