摘  要:
On the base of the analysis of the parametric line of pressing screw of variable diameters and variable pitches,the simplified equations for the line of screw teeth are achieved.Then the situations of the fillment and compression of the materiel in the chamber are discussed,and a compact model for the volume calculation of the pression screw is built.Meanwhile,this paper provides a new method for compression ratio calculation,and gives some theoretical basis for later design of the pressing screw of variable diameters and variable pitches.
