Face gear transmission is an advanced transmission mode in the aviation field, consisting of cylindrical gears and the face gear made of envelope machining. Existing studies have shown that the application of micro-texture in gears can improve their dynamic performance through lubrication and friction reduction. However, the application of micro-texture in face gear has not yet been considered, and the structural parameters of tooth texture on face gear need to be investigated in depth to improve the transmission performance of face gear. Based on the spatial tooth surface meshing theory and processing principles, the tooth surface equation of face gear is derived. A diamond-shaped micro-texture is independently designed, and establishing a model of the micro-textured face gear transmission pair including modification. Through fluid simulation, the oil film bearing force and friction coefficient performance of the textured units under different structural parameters are analyzed. Furthermore, different texture structure parameters are set up to solve the dynamics simulation of micro-texture face gear transmission system using the finite element method. Considering both surface morphology changes and lubrication effects, the influence of micro-texture on the vibration response of the face gear transmission system is comparatively analyzed in the time domain and frequency domain, which will provide targets for the subsequent processing of micro-texture on the tooth surfaces of face gear.
