A finite element analysis of bending stresses induced in external and internal involute spur gears

Abstract

This paper describes the use of the finite element method for predicting the fillet stress distribution experienced by loaded spur gears. The location of the finite element model boundary and the element mesh density are investigated. Fillet stresses predicted by the finite element model are compared with the results of photoelastic experiments. Both external and internal spur gear tooth forms are considered.
