3、 lifting equipment, besides, it has small size and portability, and low cost, so it is widely used in our daily life.Spiral jack is consist with screw, nut, handle, base, large bevel gear, rundlet gears, racks, ratchet s

4、et, lifting the sleeve and other parts. It is most important to calculate the Spiral driven and design and selection for the parts, in this design process; what is more, used the knowledge of mechanical design, in additi

5、on to used CAD tools such as AutoCAD, Pro / E and so on. This article described the whole process of its design from the spiral jack design to the selection of components and other aspects. It was precisely calculated be

6、cause it used a large number of scientific processing theory and formula, especially in process planning. In the spiral transmission part, through the calculation of wear resistance, stability check of the screw, screw

7、mechanism of the resistance calculation, the calculation of the nut thread teeth, self-locking of the check and a variety of strength calculation. Through a variety of scientific calculations the screw jack designed will

8、 meet the actual demand. In this design, we used Pro/E to design a number of parts and transmission of three-dimensional modeling, it clearly show the various parts of the shape and structure.Keywords: spiral, screw tran
