ABSTRACT:
A fuel pump drive gear assembly is provided which includes torsional absorption elements positioned between a drive gear and a fuel pump hub. The drive gear includes a plurality of apertures for receiving a plurality of projections formed on the fuel pump hub. The torsional absorption elements are positioned in the apertures between the projections and the drive gear so as to frictionally engage a surface of both the projection and the drive gear, thus creating a mechanical driving connection between the rotating drive gear and the fuel pump hub. The torsional absorption elements have adequate stiffness to provide the necessary torque to drive the fuel pump, while retaining sufficient flexibility to permit relative rotational movement between the driving gear and the fuel pump hub for absorbing the vibratory loads imposed upon the gear assembly by the fuel pump without compromising the timing between the fuel pump and engine.
