【Abstract】This paper conducts research on the optimization of gear meshing performance in automotive power transmisionsystems.Firstly，it explains the principleof gear meshing，keygeometric parameters，andthe key points of materials and surface treatment; Secondly，it analyzes the influence mechanism of meshing performance on transmision eficiency，vibration noise，and system stability and durability，and reveal the action laws of core factorssuchastoothsurfacefriction，impactlos，andstifnessfluctuation;Finally，theotimizationtechnicalpaths are proposed，including the numerical simulationand optimization technology of multi-physics field coupling，the inteligent manufacturingand precisioncontrol technologydrivenbyclosed-lopcontrol，as well astheintegrated development direction of functional integration and intelligent self-adaptation. Research shows that modern gear designeeds tobreak throughthelimitationsof traditional experienceandbuildafullchaindataintegrationsystemof "design- manufacturing - operation". Precision manufacturing should establish a real-time monitoring and automatic corrction mechanism.Thedevelopment of inteligence requires adeep integrationof electromechanicalcharacteristics andactiveregulationcapabilities.Inindustrialpractice，itis necessry tenhancecros-domaincollaboration，develop embedded perceptionand adaptive execution units，and establish a performance degradation early warning mechanism to improve theabilityof geardevices to autonomously maintain theoptimal working stateand provide reliable power transmission support for high-end equipment.
