Abstract An assembled camshaft is disclosed, comprising a shaft tube and elements such as control cams, bearing rings, gear wheels, or beveled gears, which are slid onto the shaft tube and fixed in position by expanding the shaft tube in the region of the slid-on elements by the application of internal pressure. By subjecting longitudinal portions of the shaft tube to plastic deformation in the region of slid-on elements undergoing predominantly elastic deformation, it has been found that a torque-transmitting fit of elements may be achieved without any thermal processing, thereby avoiding dimensional changes typical of prior art camshafts.
