    摘要: The invention relates to a camshaft adjuster (1) for adjusting and fixing the relative position of the angle of rotation of a camshaft (8) in relation to a crankshaft of a reciprocating piston internal combustion engine. The adjusting device comprises a high transmission and friction-reduced adjusting gear mechanism (2), comprising a drive shaft which is rotationally fixed to the crankshaft, a driven shaft which is rotationally fixed to the camshaft (8) and an adjusting shaft (9) which is connected to an adjusting motor shaft (10) of an adjusting motor. A camshaft adjuster (1), which is economical to run, can be produced such that the adjusting gear mechanism (2) and the adjusting motor (3) are embodied as separate units and are connected together by a rotational backlash-free, disengaging coupling (4).

    摘要: A device for electrically adjusting the relative rotation of two shafts, particularly a camshaft (15) in relation to a crankshaft of an internal combustion engine is provided. The adjusting device includes an adjusting gear system which is embodied as a triple-shaft gear mechanism and is provided with a crankshaft-fixed input part, a camshaft-fixed output part, and an adjusting shaft (13) that is connected in a torsion-proof manner to an electric adjusting motor shaft (32) of an electric adjusting motor (3). The adjusting motor (3) is configured as a brushless DC motor having a housing-fixed stator (35) and a permanent magnet rotor (34). A high degree of adjustment accuracy and adjustment speed are provided with minimal space requirements and low power consumption. This is achieved through the use of a double eccentric gear mechanism (2) and a double planetary gear mechanism, which are provided with a speed reduction of up to about 1:250 and low friction, as an adjusting gear system while using a highly inductive permanent magnet rotor for the adjusting motor (3).
