Camshaft adjusting arrangement
First Claim
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 camshafta 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, andwherein 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, andwherein the groove-like recess has largely radially extending lateral boundaries at circumferential ends of the groove-like recess.

Abstract
A camshaft adjusting arrangement for varying angular position of a camshaft relative to a crankshaft of an internal combustion engine which has a drive element that is driven by the crankshaft and is rotatable in relation to the camshaft, at least two hydraulic chambers, to which a hydraulic fluid can be admitted to set a defined relative rotational position between the drive element and camshaft, formed between the drive element and camshaft, a first component and a second component. The first component has a cylindrical receiving face which receives a cylindrical seating face of the second component. To keep the resulting radial compressive stress between the components within an admissible range, 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.
