Abstract
At present, our C system C lathe is in by the research development phase to the popularization and application of key transitional stage moments, but125 special instrument C lathe is one of C lathe. And125 special C lathes in transmission mechanism of this type of lathe is one of the ponents. This design is125 special instrument according to technical specifications C lathe of major institutions horizontal and vertical lathe to carry on the design. In the design of the detailed specific selection and calculation of ponents, such as: machine tool power and motor selection, ball screw vice selection and calculation checking, plan design will give longitudinal and transverse lathe, the design of gear on axis and the strength, stiffness checking related parameters selection, and the necessary parameters such as check calculation.
Keywords: Instrument C、drive system
