Influences of the Residual Stress Condition on the Load Carrying Capacity of Case Hardened Gears


Compressive residual stresses, such as those generated by shot peening, result in an increased tooth root bending strength. The author's investigations show that shot peening can increase the load carrying capacity of case hardened gears significantly. Correlations between the residual stress state and the load carrying capacity limits were determined. This paper will give an overview of the main results of different investigations and discuss influences of the residual stress condition on different failure modes of case hardened gears.
