摘　　要：在CW6163车床数控化改造中,滚珠丝杠副由于其传动精度高、传动效率高等优点被用作传动机构。对CW6163普通车床纵向进给系统改造过程中滚珠丝杠副的选型、计算、承载能力的校核进行了介绍,分析了滚珠丝杠副的热误差、螺距误差、加工误差及耦合误差等,为机床数控化传动机构的改造及误差分析提供参考。In transformation of NC for CW6163, the nut set of ball screw is used as transmission mechanism due to its advantages of high driving accuracy, high transmission efficiency. Checking calculation, lectotype, checking of bearing capacity of the nut set of ball screw are introduced for modifying the engine lathe into the economical numerically controlled lathe, and the thermal error,pitch error, machining error, coupling error of the nut set of ball screw are analyzed in this paper,which can be used as a reference of the transmission mechanism of the transformation of NC machine tools and error analysis.
