设计简介
摘 要：本文主要是对螺旋榨油机的总体结构设计。其中包括压榨部分，传动部分，机架部分，出油装置及进料等的结构设计。包括对输入端电动机功率／转速的选择。带及带轮的选择及设计。变速箱中齿轮的设计，轴的设计，轴承、键、联轴器的选择及相关的计算、校核。榨螺榨笼的设计等。其中榨螺和榨笼是榨油机的主要工作部件。榨螺部分主要有榨螺轴和榨螺（共3节）．调饼头．锁紧螺母和调节螺栓等组成．榨螺的设计应满足榨螺间的装配要求．榨螺间装配必须严密．用锁紧螺母将其夹紧．防止油饼渗入榨螺孔内，影响榨螺的顺利拆卸．榨笼的榨膛由两部分组成．前段由榨条组成，后段落由榨圈组成．变速箱的设计应注意互相间的配合关系，传动比及扭矩是否满足工作条件等．本机适用于榨取菜籽、花生仁、芝麻、棉籽仁、大豆、椰子、茶籽、葵花籽等植物油脂。（根据用户需要，可更换榨螺，用于榨取米糠等含油的油料。）

Abstract：This paper is the overall structure design of screw press. Including press parts, transmission parts, chassis parts, the structure design of oil device and feed etc.. Including the motor input power / speed selection. The selection and design of belt and pulley. Transmission in gear design, shaft design, bearing, bond, options and related coupling calculation, checking. Screw squeezing cage design etc.. The screw and barrel is the main component of oil press. Screw mainly consists of a screw shaft and screw. Adjustable cake head. The lock nut and an adjusting bolt etc.. Design should meet the requirements of the press screw assembly screw the screw assembly must be strict. Through a locking nut clamping. Prevent the cake into the pressing screw effects of screw, the smooth demolition. Pressing cage pressing chamber consists of two parts. Section by pressing strip, after paragraph by the pressing ring. Attention should be paid to coordination between design of gearbox, whether the transmission ratio and torque to meet the conditions.
This machine is suitable for the extraction of rapeseed, peanut, sesame seed, cottonseed, soybean, coconut, tea seed, sunflower seeds and other plant oils. (according to user needs, can replace the screw, for oily extract rice bran oil.)
