Abstract This graduation project focused and concise language the ordinary milling machine design transformation process, first introduced by the significance of the research background and Selected Topics, leads to the significance of this design. Then prepared from the parameters, transmission, transmission of the design estimates and checking ministries structural design and the design of the spindle components, checking the design of various components, and then through the assembly drawing. Parameter design of gears, pulleys, pulleys, bearings, cabinet.
The main method used in the development process of this project are: 1. To collect relevant information and books of the milling machine spindle gearbox. 2.Read literature to understand the current milling spindle gearbox structure and characteristics of the work, understand the general design of the milling machine spindle gearbox structure and ideas. 3 .based on reading the relevant information literature, prepared the feasibility of milling spindle gearbox design program. 4.Familiar with AutoCAD software in all aspects of operations, expansion plan for the future spindle box (assembly diagram), the spindle would like to expand the map section map, part drawings to prepare.5. Consult the manual, complete the design and selection of the various systems of the spindle gearbox. 6.Pros and cons of assessment, the design of the milling machine gearbox design and optimize the final design results.
