In the market demand, the 6th nuclear institute developed the SDQ-4000P CNC plasma cutting machine and got a very good market response. Today, my design inherit the project of the 6th nuclear institute, designing the cutting machine main drive and giving out the corresponding simulation. Under the guidance of the teacher Zhao, i come to understand the relationship between parts of the assembly, designing elements, and finally solve the high precision of the cutting machine. ??????The focus of this design is the gear and shaft design of CNC plasma cutting machine main drive. Design includes the choice of motor, the distribution of contact ratio, the calculations of three pair gear design, the design and verification of shafts, the selection and verification of bearings, the solutions of motion stabilization, the guarantee technique of motion accuracy. At the same time, i must catch the kernel of the selection of proper design of machine, the movement characteristics, the dynamic characteristics, the main wheel and auxiliary wheel frame design requirements.
