ABSTRACT:
A drive wheel for centerless drive of an annular saw blade of a cutting machine. The drive wheel includes a drive ring having concentrically arranged first and second annular elements, each of which has a first beveled side surface located radially outward from a second beveled side surface. The second beveled side surfaces are in contact with one another and the first beveled side surfaces together define a wedge-shaped drive groove for the inner edge of an annular saw blade that is to be driven by the drive ring. Third and fourth annular elements are arranged concentrically with, and outboard to the first and second annular elements located therebetween. The third and fourth annular elements are configured to inwardly compress upon the first and second annular elements. An anti-relative-rotation member interconnects the first and second annular elements to prevent relative rotation therebetween while driving the annular saw blade of a cutting machine.
