) I ;;;;;; Abstract First, in order to obtain the ideal and more understanding of the design method of transmission system design of machine tool transmission system when the winner. According to the requirements of the main drive system of CNC machine tool and spindle power and torque characteristics, analysis of the design principle and method of mechanical and electrical connection and speed of main transmission system. Starting from the main drive system structure network, determine the optimum matching scheme of machine tool spindle power and torque characteristics, the calculation and verification of relevant motion parameters and dynamic parameters. Design steps and design method of this specification focuses on the main drive system of machine tool, according to the motion parameters have been determined by transmission center distance of expansion graph of the minimum as the goal, formulate transmission scheme transmission system, in order to obtain the optimal scheme and high design efficiency. In the main drive syst
