【Abstract】 The tooth surfaces of a face gear are too complex to accurately describe with the traditional analytic method. The tooth profile change of the face gear is analyzed with the cross section method,and a new modeling method of tooth surface extraction after gear shaping simulation is proposed. Based on the tooth surface generation principle,the tooth surface equation is deduced and the specific parameters of the face gear and the cutting tool are determined. Based on the gear shaping principle,the motion model for the surface gear blank and the cutting tool is established,and the simulation of face gear shaping is carried out with SIEMENS NX software. The accurate model of the face gear is established with new modeling method. As a result,the correctness of the tooth shaping simulation and the feasibility of the tooth surface extracting modeling is verified.更多还原
