ABSTRACT:
A spline roller having a cylindrical barrel having a length, a first and second end, a centerline, and a circumferential surface, and at least a first drive portion formed integrally into the circumferential surface, having a first end and a second end, at least a first circumferential recess at the first end, and comprising a plurality of the parallel, radially-disposed, splines about the circumference, each spline extending along the length of the barrel from the first circumferential recess. Each spline has a ridge extending from the first end to the second end, and typically has a crown along the length of the ridge. The ridge can be oriented along a line that is parallel to the centerline of the spline roller, to provide a straight spline roller. The ridge can also be oriented along a line that is angled inwardly at a taper angle toward the centerline of the roller, to provide a tapered spline roller. Typically, each roller has a second drive portion adjacent to and axially disposed from the first drive portion.
