The Key Design Technology Research Of The Twin-scrw Oil Press

A new twin-screw press was developed for expressing oil from high oil content seeds or special oil seeds. Its squeezing chamber adopted double-step and multiple-stage form, in which two counter-rotating parallel screws were horizontally assembled, with one directly beneath another. The worms in the feed section took the form of partially meshing that means clearance existed between each meshing flights in the longitudinal direction but they overlapped in the transverse direction; in the ram section, non-intermeshing form was taken.The layout of transmission system was used which has two shafts and the deceleration and torque transmission part was separated from two boxs. The parameters's ascertainment and deformation correction of gear ,the selection and structure layout of bear,the proof of gear shaft and so on in the transmission system were described in detail . The 3-D model of the deflected gear and squeeze screw were completed through the three-dimensional software UG and Solidedge.Moreover, the position of key slot was reversed through the squeeze screw shaft virtual assembly and the explosion view of torque distribution box which was complex was given. Finally, the gear shaft of finite element analysis was completed through the ANSYS , and the gear shaft's stress-strain diagram was obtained ,then the reasonable improvement measures was proposed based on the results in order to improve the transmission system.
