Abstract：[Significance]Gears are central components of power transmission systems,and their surface integrity fundamentally dictates the reliability and fatigue life of high-end equipment.Ultrasonic vibration-assisted grinding(UVAG)introduces high-frequency vibration energy to mitigate excessive cutting forces and frictional heat accumulation,which are critical challenges in the precision manufacturing of high-performance gears.[Analysis]Through a systematic review of existing literature,firstly,the evolutionary trajectory and core technical specifications of gear UVAG equipment were delineated.Secondly,the regulatory mechanisms of ultrasonic vibration on material removal behaviors were investigated based on surface integrity characterization methods,such as surface roughness,residual stress distribution,and subsurface damage control.Technical characteristics of different vibration application modes were comparatively analyzed.[Conclusions]Ultrasonic-assisted machining can significantly reduce grinding force and grinding temperature,improve the physical and mechanical properties of the gear surface layer,and possesses unique technical advantages and engineering application potential in the field of precision machining.[Prospects]Future research should focus on the deep integration of ultrasonic vibration systems and grinding processes,explore the evolution law of surface quality under multi-physics field coupling,and strive to develop large-scale and high-frequency complete UVAG equipment.
