Camshaft and method for producing the camshaft

A camshaft, comprising:

• components including at least one cam and each having a hole formed therein;
• a support tube defining predetermined seat positions and supporting said components including said at least one cam at said predetermined seat positions, said support tube at least partially extending through said hole in each of said components and an interference fit assembly between said support tube and said components is formed by means of internal high-pressure forming;
• and
• at least one locally formed material molding disposed between said support tube and said hole, through said at least one locally formed material molding said components are held in said predetermined seat positions in a desired orientation relative to said support tube such that said support tube with said components can be fed to the internal high-pressure forming.

A method for producing a camshaft having a support tube, on which at least one component including at least one cam, is disposed in a predetermined seat position, which comprises the steps of:

• providing the support tube and the at least one component;
• introducing at least one material molding in an outer surface of the support tube in a region of the predetermined seat position or in a hole of the component, the hole being formed in the component for disposing the component on the support tube;
• rotationally fixed prepositioning the component in the predetermined seat position by forming at least form-locking connection of the component with the support tube in a region of the material molding;
• and
• creating an interference fit assembly between the support tube and the component by means of internal high-pressure forming subject to forming a required connection strength between the component and the support tube.
