Abstract:
1. A non-splined cam connecting shaft for forming a non-splined camshaft, comprising: a metal bar having a first end which is non-splined and a second end which is non-splined; a first end coupler integral to or rigidly mounted on the first end of the metal bar and adapted to be boltingly connected to a coupling end of a first cam section by a first plurality of bolts inserted into a first plurality of holes in the coupling end of the first cam section; and a second end coupler integral to or rigidly mounted on the second end of the metal bar and adapted to be boltingly connected to a coupling end of a second cam section by a second plurality of bolts inserted into a second plurality of holes in the coupling end of the second cam section; wherein the first end coupler has a first alignment hole adapted to receive a first alignment means which is adapted to fit into a corresponding first alignment hole in the coupling end of the first cam section, and wherein the second end coupler has a second alignment hole adapted to receive a second alignment means which is adapted to fit into a corresponding second alignment hole in the coupling end of the second cam section, and wherein the second alignment means, when in the second alignment hole of the second end coupler, has a position relative to the first alignment means in the first alignment hole of the first end coupler selected from the group consisting of 45° clockwise, 90° clockwise, 45° counterclockwise, 90° counterclockwise, 135° clockwise, 135° counterclockwise, 180°, 144° counterclockwise, 72° clockwise, 120° clockwise, and 120° counterclockwise; and wherein when the non-splined cam connecting shaft is connected to the coupling end of the first cam section and to the coupling end of the second cam section, a non-splined camshaft is formed, said non-splined camshaft having zero degree backlash.
