ABSTRACT:
An improved disk harrow C-spring with a tapered cross section which reduces the compressive stresses in the inside radius and improves vertical and side-to-side flexibility. The curved portion of the C-spring has a constant cross section at the top and around three-fourths of the bend. At a location on the bend 45 degrees down from the horizontal, the thickness tapers to a location forward of the bearing hanger. The cross section is constant from the end of the taper to the end of the spring. The tapered cross section allows a thicker section to be used on the most highly stressed areas in the upper quadrant of the curved portion of the C-spring. The lower quadrant taper results in uniform stress distribution along the entire C-spring with the maximum compressive stress on the inside radius reduced substantially over a conventional C-spring. In addition, the tapered design provides an increase in both vertical and side-to-side flexibility for improved operation in rocky soil.
