Abstract：The assembly precision of gears in aero-engine transmission systems is relatively high，yet controling the deformation of assembly dimensions after heat treatment presents significant challenges.The deformation of parts cannot be effectively controlled after alkali bath free quenching，which seriously affects the assemblyand use of gears.This study focuses on the 16Ni3CrMoE steel output gear as the research object，and the key dimensions of the partsarelimited tocontrolthe deformationoftheparts bypressngoilcold quenching insteadofalkali bathfree quenching.The microstructure，hardness，propertiesand dimensions of the parts quenched by the two methods are compared and analyzed.The results show that the deformation of the parts can be efectively controlled by the coldquenching process of the moulded oil， and the machining of the parts can meet the technical requirements.
