摘　　要：依据弧齿锥齿轮齿面数学模型,对齿面进行了离散化处理,结合旋转投影原理,确立了弧齿锥齿轮齿面离散点三维坐标的计算方法,进行了齿面离散点三维坐标实例计算;并采用NURBS方法建立了弧齿锥齿轮齿面三维模型,分析了弧齿锥齿轮机床运动误差对齿面误差的影响,并通过弧齿锥齿轮齿面离散点误差计算和分析对其影响规律进行了研究,可以为弧齿锥齿轮齿面误差补偿及弧齿锥齿轮加工机床精度设计提供理论参考。A study of the effect of spiral bevel gear machine tool’s motion errors on tooth surface errors was presented.The tooth surface was discretized,and one method for calculating the three-dimensional coordinate of the discrete points on the tooth surface of spiral bevel gear was developed with rotary projection principle and mathematical model of tooth surface.One computation example was done and the three-dimensional tooth surface model was established with the calculation result using the method of NURBS.Relation between machine tool’s motion errors and tooth surface errors was researched based on computation example.These works are helpful to the compensation of tooth surface errors and the precision design of spiral bevel gear machine tool.
