Figure separately forgear and for pinion. (See table of sines and cosines.) Pitch Angle is found from a table of Tangents. The numberof teeth in a gear (or pinion) divided by the number ofteeth in its mate gives the Tangent of the Pitch Angle. Face Angle is Pitch Angle added to Addendum Angle. Addendum Angle is found from tables of Sines and the sine of pitch angle divided by the number ofteeth gives the Tangent of Addendum Angle. The Hamilton Gear & Machine Co. Cor.
