METHOD FOR PRODUCING A CAM PROFILE OF A CAM PACK OF A CAMSHAFT, AND CAMSHAFT
A method concerns producing a cam profile of a cam pack with at least two cam elements that can be adjusted relative to each other. The camshaft may comprise an outer shaft, a rotatable inner shaft, a fixed cam element connected to the outer shaft, and an adjustment cam element connected to the inne...

| description | A method concerns producing a cam profile of a cam pack with at least two cam elements that can be adjusted relative to each other. The camshaft may comprise an outer shaft, a rotatable inner shaft, a fixed cam element connected to the outer shaft, and an adjustment cam element connected to the inner shaft. The method may comprise processing an adjustment cam contour by a continuous diameter reduction of a segment of the adjustment cam base circle, wherein the adjustment cam base circle is reduced to a diameter that is smaller than a fixed cam nominal circle diameter minus a doubled adjustment cam base circle tolerance. The method may comprise processing a fixed cam contour by reducing a fixed cam contour protrusion in a region between a transition point and a processing point. Upon reaching the transition point a tapping element for converting a revolving motion of the cam elements into a linear motion of the valves is transferred from the fixed cam element to the adjustment cam element. |
