摘　　要：主轴部件是机床最重要部件之一,主轴跨距是影响机床动、静刚度的重要因素。对拟开发的某型数控车床主轴进行研究,通过对二支承非卸荷式皮带轮传动主轴进行静力分析的基础上,建立了数学模型,利用卡丹公式对主轴最佳跨距和静刚度进行求解;通过ANSYS Workbench软件对主轴部件进行了有限元分析,证明主轴最佳跨距的可行性。Spindle components are one of the most important components of machine tools and are important factors affecting the dynamic and static stiffness of machine tools.A certain type of CNC lathe spindle to be developed is studied.Based on the static analysis of the two-support non-unloading pulley drive spindle,a mathematical model is established.The optimal span and static stiffness of the spindle are solved by the Kardan formula.The finite element analysis of the spindle components is carried out by ANSYS Workbench software to prove the feasibility of the optimal spindle span.
