Its movement is part of the rotary body movement, resulting in a relatively large centrifugal force will be separated from solid. At home and abroad at home and abroad a wide range of threedimensional centrifuge, but the basic structure are similar. Threelegged centrifuge with its base for the three support foot named. Based on the principle model of the threelegged centrifuge, the research in other fields is being more extensive. Through the mechanical design, mechanical principles and other design content, refer to some of the research papers and literature, bined with the experimental results to access the relevant books to understand and calculate the three dimensional centrifuge structure size. The three dimensional model of the threedimensional model of the structure and the twodimensional map, the choice of materials, transmission system design, focusing on the drum and the shaft strength calculation, the final design of threelegged Centrifuge structure. Key words: three legged centrifuge。 strength calculation III 目錄 摘 要 ................................................................
