The total stresses in a mating gear pair arise from two sources:1) externally induced stresses associated with the transmission ofpower, and 2) residual stresses associated with the heat treatmentand machining of the tooth profiles. The stresses due to powertransmission are the result of complex normal and shearing forcesthat develop during the meshing sequence. The total stress fromthese two sources contributes to the life of a gear. This paper,funded by the AGMA Foundation, presents the results of researchdirected at measuring the total stress in a pair of staticallyloaded and carburized spur gears. Measurements were made usingneutron diffraction methods to examine the change in total stressas a function of externally applied load and depth below thesurface. The paper includes a summary of the various test methodsthat were used and a discussion of their applicability tocarburized gears.
