中文摘要：

为了建立齿廓为双圆弧齿面齿轮的三维模型，在建立刀具、面齿轮坐标系和坐标变换矩阵的基础上，利用微分几何和齿轮啮合原理推导了该面齿轮的齿面方程。根据此齿面方程利用Pro／E软件仿真建立了三维实体模型，三维实体模型的成功建立也进一步验证了齿面方程公式的正确性。

英文摘要：

In order to establish the 3D model of the double circular arc tooth face gears, On the basis of the coordinate cutting tool and face gears and the coordinate transformation matrix ,using the theory of the meshing principle and differential coefficient geometry, educing the face function for the double circular arc tooth face gears, according to face function an the software PRO/E established the 3D model, the successful establishing of the 3D model verified the right of the face function.
