Abstract

Recent research by the authors has shown that it is possible to generate fully interchangeable 20° involute gears using nonstandard module and pressure angle cutter geometry. Gear teeth cut by this method have working profiles that are identical to standard teeth, but notably different trochoidal fillets. In this paper the possibility to use this method to derive teeth with improved bending resistance is investigated numerically using Finite Element Method (FEM) for the entire possible range of values of the cutter pressure angle, thus providing a parametric mapping and a first suggestion for optimal design.
