Abstract: This paper uses the ANSYS software to do the finite element analysis of deflection of short fiber rubber sheeting mill roll. According to the analysis of the mill roll under different horizontal pressure, obtain analysis data of deflection of different mill roll diameters. Then according the technological parameters required to select the most appropriate mill roll diameter.

Abstract: This thesis presents one kind of new moulding technology of screw drill stator bushing--one-step injection moulding technology, based on which the one-step injection moulding equipment is developed. In the meantime, the compounding to produce screw drill stator bushing is proposed. Experiment on this equipment and the compounding proved this equipment has energy-saving, room-saving, structure-compacting, and low labor-consuming qualities. Moreover, the products have higher density, longer service life, and lower rejection ratio.
