Abstract: Gears are the core components of electric drive transmission systems in new energy vehicles, exerting a significant impact on vehicle performance. With the rapid increase in new energy vehicle penetration rates and the continuous enhancement of power density in electric drive transmission systems, gears now face high-service-performance challenges including high-speed operation, low noise, and fatigue resistance. Achieving high-efficiency precision machining represents the fundamental approach to ensuring their superior service performance. However, there are still some difficulties in the efficient precision machining of new energy vehicle gears, including the generation mechanisms, key technologies, and machining equipment. This paper systematically reviews current research progress regarding the high-performance tooth surface generation mechanisms, key technologies for efficient precision machining in typical processes such as worm wheel grinding and internal meshing power honing, as well as advanced gear machining equipment. It further summarizes and prospects the development trends of high-efficiency precision machining technologies for gears, providing theoretical and technical guidance for subsequent research.

Key words: gear, worm grinding wheel for gear grinding, power honing, complex shaping, surface integrity
