Abstract Through research on involute spiral bevel gear and starting from the tooth profile meshing law, an accurate modeling method irrelevant to machining method for involute spiral bevel gear was proposed. Based on the above theory, an OpenGL-based special modeling software for involute spiral bevel gear was developed, which integrated geometry design, dynamic simulation and mechanism calculation together. Through convenient parameter input, the 3D solid modeling of involute spiral bevel gears was generated automatically. During the modeling process, spherical involute was established directly by equations to guarantee the accuracy of tooth profiles, which provided accurate model for consequent finite element mechanism calculation of involute spiral bevel gears．
