METHOD OF INTRODUCING RESIDUAL COMPRESSIVE STRESSES INTO A SHAFT, IN PARTICULAR INTO SHAFT NOTCHES

摘要

The invention relates to a method of introducing compressive residual stresses into shaft notches of a shaft (1) which is configured as a stepped shaft having successive stages (2) having a different diameter (D). Diameter transitions (3) or notch regions are located between each two adjacent stages (2). The diameter transitions (3) or notch regions are quenched in a controlled manner as part of a heat treatment of the shaft (1).
