Mobility electrification has impacted the vehicle systems' design requirements. Geometrical accuracy and surface integrity are critical fields affecting the functional performance of the powertrain components. By the matchmaking between these two localized demands, the grinding and shaving gear finishing routes were assessed regarding their influences on actuating and permissible stresses. While in the grinding route the finishing process was the final step, at the shaving route the gear finishing occurred in the soft machined condition, before case hardening. The objective is the comprehension of how surface integrity heterogeneities induced by distinct gear finishing routes affect their capability to meet the electromobility flank quality requirements. Dimensional analysis of samples revealed that both chains generated better tolerance classes than demanded, especially grinding. When the manufacturing deviations were assessed in face of the e-mobility gear requirements, tooth contact analyses demonstrated that profile form and helix slope deviations highly impact the fatigue life, while pitch deviation has a large influence on noise generation. Still, the higher speed rotations of the electric motors were shown to intensify the influence of the deviations on the contact. Depending on the electromobility application and its main demands, specific flank deviations require increased tolerance control. Investigations on surface integrity along both finishing chains evidenced that distinct residual stress profiles and heterogeneities were generated, as stated by the Design for Residual Stress (DRS). The grinding chain led to a more compressive residual stress state and high homogeneity, which tends to improve gear fatigue lifetime and, so, is a good alternative to deal with the high power densities of electric vehicles. The shaving route gears presented a highly stable profile, thus leading to lower tendencies for relaxation during operation, which is beneficial given the steep torque transients of the electrified vehicles. When the effects of the chains on both actuating and permissible stresses were considered, the ground samples were identified as more prone to subsurface-originated failures, while the shaved gears were to surface-originated failures. The results demonstrated that finishing routes for e-mobility gears must be selected to obtain not only highly accurate gears, but a group of surface integrity characteristics that benefits the operation, being necessary the DRS concepts.
