Comparison of internal gear root stresses at (tooth #1) and away from (tooth #5) an outer spline location
Grahic Jump Location
Critical principal stresses as a function of Λ; (a) the internal gear, and (b) planets and the sun gear. The stress values are normalized with respect to the stress values when Λ=∞
