Preassembly of a camshaft phaser

Abstract

A camshaft phasing system ( 10 ) for an internal combustion engine ( 6 ) includes a camshaft ( 16 ) and a camshaft phaser ( 15 ) that is axially slid onto the camshaft ( 16 ) and that has stator ( 34 ) and a rotor ( 36 ) driven by the stator ( 34 ), whereby the rotor ( 36 ) is mounted rotatably relative to the stator ( 34 ). A bushing ( 26 ) that is secured on the camshaft ( 16 ) is provided, whereby the camshaft phaser ( 15 ) is tightened on the camshaft ( 16 ) against the bushing ( 26 ). Moreover, a drive has an internal combustion engine and such a camshaft phasing system.

What is claimed is: 
     
         1 - 10 . (canceled) 
     
     
         11 . A camshaft phasing system for an internal combustion engine, the camshaft phasing system comprising:
 a camshaft;   a camshaft phaser axially slid onto the camshaft and having stator and a rotor driven by the stator, the rotor being mounted rotatably relative to the stator; and   a bushing secured on the camshaft, the camshaft phaser tightened on the camshaft against the bushing.   
     
     
         12 . The camshaft phasing system as recited in  claim 11  wherein the rotor is tightened on the camshaft against the bushing. 
     
     
         13 . The camshaft phasing system as recited in  claim 11  wherein the bushing is held on the camshaft via a press fit. 
     
     
         14 . The camshaft phasing system as recited in  claim 11  wherein the camshaft has an axial stop for the bushing. 
     
     
         15 . The camshaft phasing system as recited in  claim 11  further comprising a nut for tightening the camshaft phaser against the bushing. 
     
     
         16 . The camshaft phasing system as recited in  claim 15  wherein the nut tightens the rotor. 
     
     
         17 . The camshaft phasing system as recited in  claim 11  wherein the stator is mounted radially on the bushing. 
     
     
         18 . The camshaft phasing system as recited in  claim 11  wherein the camshaft phaser is frictionally connected to the bushing. 
     
     
         19 . The camshaft phasing system as recited in  claim 18  wherein the rotor is frictionally connected to the bushing. 
     
     
         20 . The camshaft phasing system as recited in  claim 11  further comprising an outer tubular camshaft, the camshaft being held concentrically in the outer tubular camshaft, the outer tubular camshaft being connected to the stator of the camshaft phaser. 
     
     
         21 . The camshaft phasing system as recited in  claim 20  wherein the outer tubular camshaft and the stator of the camshaft phaser are positively connected. 
     
     
         22 . The camshaft phasing system as recited in  claim 21  wherein teeth positively connect the outer tubular camshaft and the stator. 
     
     
         23 . A drive comprising:
 an internal combustion engine having a driven shaft; and
