Gears for aerospace, naval and renewable Industries
Residual stress is a dominant factor in the fatigue performance of gear components. Compressive residual stress reduces the effective stress experienced in the gear tooth under a tensile applied bending stress. For gears, particular attention must be paid to the effect of surface treatments such as peening or induction hardening. The use of STEELAR´s surface penetration technology has the additional potential to be used for evaluation of gear tooth stress distribution.
