This study presents a parametric analysis to investigate the effects of gear design parameters on strength, efficiency, and noise characteristics for an electric drive system. The analysis was conducted under a single operating condition with an input speed of 2,000 rpm and a transmitted torque of 72 Nm, while the center distance was fixed. The module, number of teeth, pressure angle, face width, and helix angle were selected as key design variables. The results indicate that gear strength is mainly influenced by the face width and module, while gear noise, evaluated based on transmission error, shows high sensitivity to the pressure angle and helix angle. In addition, minimized peak-to-peak transmission error was observed when the mesh ratio approached integer values. These findings provide practical guidelines for low-noise gear design in electric drive systems.
