  • W-N gear having a maximum surface strength
    Patent number: 4121482
    Abstract: A W-N gear which has a surface strength at least nearly maximized for a given addendum and minimum pressure angle is realized by selecting a mean radius for the convex and concave circular arcs of the tooth profile in an appropriate range. Also, a dual=line mesh W-N gear of the character described which has a requisite face width minimized is obtained by selecting a mean arc radius which lies in the range referred to above and enables the addendum and dedendum points of meshing contact to appear at equal angle intervals.
