摘　　要：详细研究了渐开线齿轮的有限元精确建模方法,建立了圆柱齿轮展成坐标系,基于空间啮合原理推导了啮合方程、齿面方程;发展了有限元自动建模技术,实现了圆柱齿轮任意齿的参数化建模,提高了建模效率与质量。The method of accurately establishing involute-gear finite element model is researched in detail. The coordinate systems for generating cylindrical gears were established. The meshing equation and surface equation were obtained based on space meshing principle. The technology of automatic finite element modeling is developed, which raised the efficiency and quality. Parameter cylindrical gear models with arbitrary number of teeth can be realized.
