Embodiment Construction
[0020] according to figure 1 and figure 2 The camshaft adjuster arrangement 2 comprises a camshaft 4 and a rotor 6 for a camshaft adjuster not shown in detail here, which is mounted on the camshaft 4 in a rotationally fixed manner. The camshaft adjuster is supplemented by a stator, not shown here, which is arranged concentrically in the rotor 6 .
[0021] The rotor 6 has a central bore 8 . An axially protruding cylindrical shoulder 10 is formed on the camshaft 4 , which is inserted into the central bore 8 in the assembled state. The shoulder 10 is substantially hollow and has an internal thread 12 . The fastening of the rotor 6 on the camshaft 4 takes place via a fastening element, in this case a central screw 14 screwed into the hollow shaft shoulder 10 .
[0022] The tightening torque of the central screw 14 is reduced in such a way that the non-positive connection is converted into a non-positive and frictional connection by using the tensioning sleeve 16 . In this ex...
