| 20100224145 | Built-Up Camshaft - The invention relates to a method for producing an assembled camshaft and to an assembled camshaft, with at least one functional component that is produced in a separate manufacturing process and has an inner recess for receiving the shaft. The shaft is widened at least in sections in the area in which the functional component is to be secured, and the recess in the functional component for receiving the shaft is widened in the shape of a funnel on at least one side and over at least a section of its axial length, the opening having a diameter which corresponds to at least the diameter of the widened shaft section, the outer surface of the shaft in the longitudinal direction of the shaft axis being provided with ridges which are distributed over the outer circumference of the shaft by material shaping of the outer circumference of the shaft by means of knurling. The functional component, the recess in which is substantially round, and which, in the section that is widened in a non-funnel shape, has a diameter which is somewhat larger than the diameter of the shaft adjacent to the widened section and is somewhat smaller than the diameter that is described by the ridges distributed over the outer circumference of the shaft, is first pushed onto the widened section of the shaft using the side that is widened in a funnel shape, the ridges partly becoming embedded in or being moulded into the recess in the functional component essentially by means of moulding of the material of the functional component in the area of said recess, and the functional component optionally being elastically widened to a small extent so that the functional component is force-fitted and form-fitted to the shaft. | 09-09-2010 |
