Camshaft adjuster having two ball joints

Abstract

A camshaft adjuster (1) for variably adjusting an outer camshaft (5) and an inner camshaft (7) that is arranged concentrically thereto, including a stator (2) that can be connected to the outer camshaft (5), and a rotor (3) that is arranged concentrically to the stator (2), wherein the rotor (3) can be connected to the inner camshaft (7) in the manner of a first joint (9) on a first spherical contact surface (27). In order to axially secure the rotor (3) on the inner camshaft (7), force can be applied to the rotor (3) by way of a screw (4). The screw (4) can be connected to the inner camshaft (7) in the manner of a second joint (12) on a second spherical contact surface (28). A camshaft adjuster-camshaft combination having a camshaft adjuster, wherein the outer camshaft (5) is fixed on the stator (2) in a rotationally secured manner, and the inner camshaft (7) is fixed on the rotor (3) in a rotationally secured manner.
