Defines the addendum modification coefficient (shift factor) and explains it in terms of gear design terminology. Shows the derivation of two types of helical gear design equations, one with the true generating shift factor, and the other with an addendum modification factor. Reviews a cantilever beam equation used to design equal bending strength teeth. Presents a design method, along with numerical examples, to synthesize equal strength teeth between mating a pinion and gear that may have different material properties.
