Coupling shaft, actuator, cam shaft adjustment drive and cam shaft adjuster

摘要

The clutch shaft (26) has coupling components at its both ends for a shaft angle compensating rotary coupling. An axial length of the clutch shaft is greater than maximum diameter of the larger coupling component. The clutch shaft has a cylindrically-symmetric, concave molding on its front side (30,31), where the molding is concentrically arranged to a main longitudinal axis (27) of the clutch shaft. Independent claims are included for the following: (1) an actuator with a rotor; and (2) a camshaft adjusting gear with a gear drive wheel.
