This research proposes a structured approach for the design and improvement of transmission shafts used in automotive systems, aiming to ensure infinite fatigue resistance under combined cyclic loading conditions. An iterative method was employed, incorporating the analysis of critical areas such as keyways and geometric transitions, utilizing the Maximum Shear Stress Theory as the primary indicator of failure due to fatigue. The initial design, based on static strength criteria, exhibited stress levels exceeding fatigue limits at the output keyway (237.8 MPa). Through a parametric optimization process focused on modifying diameters and fillet radii, the equivalent stress was reduced to 125.12 MPa, significantly enhancing durability without compromising functional integrity. These improvements resulted in a 12% increase in total weight. A visual tool called the "traffic light diagram" was implemented to simplify the visual verification of the design, reinforcing the proposal as an effective instrument for critical transmission components.
