摘要:
An axially-compact camshaft phaser wherein the phaser bearing flange on the camshaft, connected to a timing chain sprocket or cam drive gear, is axially inverted in comparison to prior art cam phasers so that the bearing flange extends axially and inwardly of the phaser stator and rotor such that radial drive load on the phaser is sustained within the hydraulic portion of the phaser rather than externally thereof. The overall axial length of the phaser may be reduced thereby by about 25% relative to some prior art phasers and the Phaser Envelop volume may be reduced by 15% while maintaining an equivalent torque capacity.
