Abstract:
1. A camshaft adjusting arrangement for varying an angular position of a camshaft relative to a crankshaft of an internal combustion engine, the camshaft adjusting arrangement, comprising: a drive element, which is driven by the crankshaft and is supported so as to be rotatable in relation to the camshaft, at least two hydraulic chambers, to which a hydraulic fluid can be admitted in order to set a defined relative rotational position between the drive element and the camshaft, being formed between the drive element and the camshaft a first component and a second component, the first component having a cylindrical receiving face which is designed to receive a cylindrical seating face of the second component, the first component being a cover plate of the drive element and the second component being a covering element, wherein in order to reduce a radial compressive stress between the first component and the second component, at least one compensating element is arranged in the cylindrical receiving face of the first component and/or in the cylindrical seating face of the second component, and wherein the compensating element is a groove-like recess, which extends over a defined angle over a circumference of the first component and/or the second component, and wherein the groove-like recess has largely radially extending lateral boundaries at circumferential ends of the groove-like recess.
