Abstract
A method for producing an assembled shaft, especially an assembled camshaft, whereby parts, especially cams, are placed on a shaft in predetermined axial and peripheral positions and joined by compression pressure in a friction-tight manner. The cams in the thrust direction have a lubrication groove which surrounds the inner bore thereof and which is essentially wedge-shaped with a linear or curved slope, running in the direction of the wall of the bore. When the cam is slid on the shaft into the predetermined axial position, a lubricant is introduced into the groove. This lubricant is pulled continuously groove into the inner bore of the cam during the push-on process to significantly reduce friction between the inner bore and the shaft.
