摘要
本次畢業(yè)設(shè)計(jì)是關(guān)于皮帶輸送機(jī)的設(shè)計(jì)，首先對(duì)輸送機(jī)的做了簡(jiǎn)單的概述；接著分析了輸送機(jī)的選型原則和計(jì)算方法，然后根據(jù)這些設(shè)計(jì)準(zhǔn)則與計(jì)算選型方法按照給定參數(shù)要求進(jìn)行選型設(shè)計(jì)；接著對(duì)所選擇的輸送機(jī)各主要零部件進(jìn)行了校核。最后對(duì)輸送機(jī)的主要部件進(jìn)行了分析。普通型帶式輸送機(jī)由六個(gè)主要部件組成：傳動(dòng)裝置，機(jī)尾和導(dǎo)回裝置，中部機(jī)架，拉緊裝置以及皮帶。在皮帶輸送機(jī)的設(shè)計(jì)、制造以及應(yīng)用方面,目前我國(guó)與國(guó)外先進(jìn)水平相比仍有較大差距,國(guó)內(nèi)在設(shè)計(jì)制造帶式輸送機(jī)過(guò)程中存在著很多不足。

Small portable belt conveyor design
Abstract：This graduation project is about the leather belt conveyer's design， first has made the simple outline to the conveyer， Then has analyzed conveyer's shaping principle and the computational method，then acts according to these design criterion and the computation shaping method according to assigns the parameter to request to carry on the shaping design；Then to conveyer each main spare part which chose has carried on the examination.。The popular belt type conveyer is composed of six major components；The transmission device，the airplane tail and leads the installment，middle rack，tightening device as well as leather belt. In the leather belt conveyer's design， the manufacture as well as the application aspect， at present our country and the overseas advanced level compared still had the big disparity， the home have many insufficiencies in the design manufacture belt type conveyer process。
Key words: Belt conveyer；Shaping design；Drive；Major component
