This paper reviews the significant amount of analytical work on strong gear tooth forms carried out since the classical papers of Shotter et al., and presents the results of a project which addresses a problem common to all three-dimensional photoelastic studies of root stresses in gears - that of maintaining an accurate delineation of the contact conjunction geometry throughout the stress-freezing cycle. Photoelastic model results are compared with those measured by strain gauge methods on the definitive gears.
