摘　　要：通过对渐开线弧齿锥齿轮研究,以齿廓啮合定律为出发点,提出一种与加工方法无关的弧齿锥齿轮的精确建模方法.以此理论为依据,开发了一种基于OpenGL图形内核,集几何设计?动态仿真和力学计算于一体的弧齿锥齿轮专用建模软件,通过便捷的参数输入,自动完成渐开线弧齿锥齿轮的三维实体造型.且在建模过程中直接利用方程建立球面渐开线,从而保证了齿形的准确性,为后续直齿锥齿轮的有限元力学计算提供了精确的模型.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.
