Abstract:
A method for rolling splines having opposed ends that are spaced from each other at an annular groove in a workpiece, comprising:rotatably supporting about a rotational axis a workpiece having an annular groove with an annular root surface and with side walls spaced from each other; andengaging the workpiece on opposite sides with a pair of racks that are moved in opposite directions as each other and that have teeth for rolling the splines in the workpiece and with each rack having an elongated die that is received within the annular groove of the workpiece and that has side surfaces spaced from each other slightly less than the spacing between the side walls of the annular groove such that spline ends are formed against the side surfaces of the elongated dies in an opposed and precisely located relationship at the outer extremity of the annular groove in the workpiece and with the side walls of the annular groove inwardly from the spline ends being spaced slightly farther from each other than the spacing of the spline ends from each other.
