When a spline shaft transmits a torque by meshing with the teeth of the boss, both torsional stress and flexural stress appear simultaneously at the foot of teeth. Therefore, the fatigue failure of a spline shaft can be considered as an example of the fatigue failure under combined flexural and torsional stresses. In view of the above fact, the author has proposed the equation for estimating the fatigue strength of a spline shaft, by using an expanded equation that incorporates size effect and mean stress into Gough's or Nishihara-Kawamoto's equation of endurance limit under combined flexural and torsional stresses. It is shown that the equation agrees satisfactorily with the experimental results. It is considered that the same idea might be applied to estimate the fatigue strength of other machine elements.
