摘　　要：根据传统机械式的机床结构,运用4×4Denavit Hartenberg齐次变换矩阵、齿轮啮合理论等建立了成形法加工的螺旋锥齿轮齿面偏差识别方程,提出采用截断奇异值分解法(TSVD)与L曲线法求解识别方程,得到机床的修正参数,以指导六轴五联动数控螺旋锥齿轮机床的参数调整,从而达到对齿面偏差的修正。研究表明,采用此方法修正齿面偏差效果显著,这为提高螺旋锥齿轮的加工精度提供了另一条有效途径。According to the structure of traditional mechanical machine,the tooth surface deviation identification model of forming method processing spiral bevel gear is established by the 4×4 Denavit-Hartenberg homogeneous transformation matrix,the gear meshing theory and so on.The interruption singular value resolution （TSVD） and the L curve law are proposed to solve identification equation and the machine revision parameters are obtained to adjust the parameter of 6-axis 5-linkage numerical control spiral bevel gear machine,and the deviation of tooth surface is revised.The results show that the remarkable effect on revision deviation of tooth surface to use the method.This study offers another efficient path for improving machining precision of spiral bevel gear.
