Camshaft adjuster for an internal combustion engine

Abstract

A camshaft adjuster ( 31 ) for an internal combustion engine, including a drive pinion ( 33 ) that can be connected rotationally fast to a crankshaft, a driven pinion ( 1 ) with an inner gearing ( 5 ) and arranged for rotation relative to the drive pinion ( 33 ) about an axis of rotation ( 37 ) as well as an adapter ( 13 ) that is arranged on an inner circumference ( 3 ) of the driven pinion ( 1 ) and through which the driven pinion ( 1 ) can be connected rotationally fast to a camshaft. For this purpose, the adapter ( 13 ) is fixed via the inner gearing ( 5 ) on the inner circumference ( 3 ) of the driven pinion ( 1 ). A fixing of this type enables manufacturing of a camshaft adjuster ( 31 ) with the lowest possible complexity of fabrication and correspondingly low costs.

1 . A camshaft adjuster for an internal combustion engine, comprising a drive pinion that can be connected rotationally fast to a crankshaft, a driven pinion comprising an inner gearing and arranged for rotation relative to said drive pinion about an axis of rotation as well as an adapter that is arranged on an inner circumference of the driven pinion and through which the driven pinion can be connected rotationally fast to a camshaft, in that the adapter is fixed via the inner gearing on an inner circumference of the driven pinion. 
     
     
         2 . A camshaft adjuster according to  claim 1 , wherein the adapter is pressed on an addendum circle of the inner gearing into the driven pinion. 
     
     
         3 . A camshaft adjuster according to  claim 1 , wherein the inner gearing is configured continuously in an axial direction on the driven pinion. 
     
     
         4 . A camshaft adjuster according to  claim 1 , wherein the adapter is welded to the driven pinion. 
     
     
         5 . A camshaft adjuster according to  claim 1 , wherein the adapter is configured as an end cap. 
     
     
         6 . A camshaft adjuster according to  claim 1 , wherein the drive pinion is configured as an annulus and mounted on the driven pinion. 
     
     
         7 . A camshaft adjuster according to  claim 1 , wherein the camshaft adjuster comprises a stop component for a camshaft and said stop component is counter mounted on the drive pinion. 
     
     
         8 . A camshaft adjuster according to  claim 8 , wherein the stop component and the drive pinion are welded at least partially to each other.
