摘　　要：应用计算流体力学软件Flow3D对大型螺旋锥齿轮在淬火过程中的变形情况进行数值模拟,并通过逆向反求和数模比对技术测定实际的热处理变形量,结果表明数值计算与实际测量结果较吻合,数值模拟可以有效地预测热处理后轮齿的变形情况。轮齿的热处理变形具有不均匀性,大端的变形量大于小端的变形量。凸齿面和凹齿面表现出不同的变形趋势,凸齿面主要产生负偏移,凹齿面主要产生正偏移。The CFD software Flow3 D was used to simulate the deformation of large spiral bevel gear during quenching. The displacements of gearteeth were measured by reverse engineering,which were compared with that of computer aided design（ CAD） model. The displacement of numerical simulation is consistent that of the measurement,which can well predict the heat treatment deformation of the gearteeth. The deformation is non-uniform with the heel displacement being higher than that of the toe. The displacements are different between convex and concave tooth surfaces,which is negative on the convex side and positive on the concave side.
