Abstract：

In the project, the method of mechanics of materials is used on the design of sliding spiral transmission equipment of screw presses. It is realized by calculating the stress and working pressure of teeth and choosing the parameter of structure. But the stress concentration is not taken into account in this method and it is usually the primary factor of structure destroy. The FEM is used in the paper on researching stress and working pressure of teeth. The stress and pressure of spiral transmission equipment of different materials is gained. A simple method of choosing safety factor is found by comparing the results of FEM and mechanics of materials, and it can provide the reference for design of project.
