摘　　要：目的消除滚齿机主轴组件设计过程中不同设计要素之间的相互耦合,使设计过程遵循设计行业公认的公理进行,提高机床设计效率和滚齿机主轴精度.方法应用公理设计理论,对主轴各零部件作为一个组件进行设计,系统地分析主轴的功能需求,阐述功能域与物理域的分解过程;应用有限元软件对主轴进行静力分析和热分析进行验证.结果映射出与公理设计过程相对应的设计矩阵,经独立公理和信息公理优化后得到最终的CAD模型;经有限元软件仿真得到改进前后主轴前端的变形量.结论这种方法可以在设计初期预测出设计的结果,选出合理的设计方案,改善了设计,提高了设计效率和主轴精度.The design of the gear hobbing machine spindle components involves mutual coupling on design elements between various elements affecting the design result. In order to remove mutual coupling between the different elements of the design process and improve the machine design efficiency as well as the precision of the hobbing machine spindle, the accuracy of hobbing can be increased. Taken the spindle components as an example, the various components are considered as an integrated system, the FRs and DPs of the system are analyzed by using Axiomatic Design theory, and the design matrix corresponding to the decomposition process are mapped out in this paper. After the optimization of independent axiqim and informaxion axiom , a CAD model of the spindle components is obtained. Using the FE software conducts the static and thermal analysis of the spindle and the deflection is compared during the improvement process. This design method can predict the design results during early design stage and select the reasonable design project to improve the design itself and improve the design efficiency and spindle precision.
