Multi-component, joined rotors with jointing in hydraulic camshaft adjusters tightly profiles and process for the preparation of the rotors

摘要

The invention relates to a camshaft adjusting device (1) for an internal combustion engine and a process for the production of a camshaft adjusting device comprising a stator (10) and a with the stator (10) cooperating rotor wheel (11), wherein the stator wheel (10) about an axis of rotation (12) is driven to rotate, and wherein the rotor wheel (11) can be connected with a camshaft of the internal combustion engine, wherein the stator wheel (10) radially inwardly directed stator vanes (13), between which there is at the rotor wheel (11) arranged radially outwardly facing rotor vanes (14) so that between the stator vanes (13) and the rotor vanes (14) fluid chambers (15, 16) are formed by the fluid channels (17, 18) can be acted upon with a pressure fluid, wherein the rotor wheel (11) a first partial body (19) and a second partial body (20), wherein a joint surface (19a) of the first partial body (19) and a joint surface (20a) of the second partial body (20) are joined to one another, and wherein in at least one of the joining surfaces (19a, 20a) recesses (21, 22) are introduced, in order to the fluid channels (17, 18) to form at least in sections. In order to achieve a camshaft adjusting device (1) with an improved rotor wheel (11) of the invention is to provide from two partial bodies (19, 20) is formed and the improved can be joined to one another, is provided according to the invention that in or on at least one joint surface (19a, 20a) at least one sealing means (25, 26) is provided, and the is designed in such a way that the fluid channels (17, 18) are sealed and that a defined contact of the surfaces to be brought to one another (19a, 20a) is provided.
