Method for permanently fastening cams on a carrier tube

A method for permanently fastening a cam on a cam carrier that extends axially, the method comprising:

• positioning the cam on the cam carrier in a predefined axial and angular position such that the cam carrier extends through a passage bore of the cam, wherein an end face of the cam carrier is axially aligned with an end face of the cam such that the end face of the cam carrier and the end face of the cam are coplanar;
• positioning a cam segment comprising the cam carder and the cam in or on an assembly device;
• and
• deforming the cam carder such that the cam is secured at least in a form-fitting manner or a force-fitting manner against movement in an axial direction on the cam carrier, wherein a deformation tool of the assembly device is advanced in the axial direction onto a planar portion of the end face of the cam carrier between an inner circumferential edge and an outer circumferential edge of the cam carders the deformation tool deforming the cam carrier such that material of the cam carder is forced outward in a radial direction against the cam.
