Abstract:
1. A camshaft adjuster arrangement comprising a camshaft and a rotor for a camshaft adjuster which is mounted fixedly, via a central fastening element in a central bore, on the camshaft so as to rotate therewith, and a frictional connection being formed between the camshaft and the rotor by a clamping unit, the clamping unit is a two-piece clamping unit comprising an inner taper ring and an outer taper ring, a circular receptacle for the clamping unit is formed on a side of the rotor which faces the camshaft and said circular receptacle is a radial enlargement of the central bore, and an axial face of the circular receptacle contacts one axial end of the clamping unit and an axial face of the camshaft contacts an opposite axial end of the clamping unit, and tightening the central fastening element provides axial forces that have a radial component in the inner and outer taper rings that deform the inner and outer taper rings to clamp against the rotor and the camshaft.
