摘要 本次畢業(yè)設(shè)計(jì)是關(guān)于DTⅡ型固定式帶式輸送機(jī)的設(shè)計(jì)。首先對(duì)膠帶輸送機(jī)作了簡(jiǎn)單的概述；接著分析了膠帶輸送機(jī)的選型原則及計(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。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)尾或?qū)Щ匮b置，中部機(jī)架，拉緊裝置以及膠帶。最后簡(jiǎn)單的說明了輸送機(jī)的安裝與維護(hù)。目前，膠帶輸送機(jī)正朝著長(zhǎng)距離，高速度，低摩擦的方向發(fā)展，近年來出現(xiàn)的氣墊式膠帶輸送機(jī)就是其中的一個(gè)。在膠帶輸送機(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)過程中存在著很多不足。 關(guān)鍵詞：輸送帶；傳動(dòng)滾筒；托輥；制動(dòng)裝置；改向裝置；拉緊裝置 Abstract The design is a graduation project about the belt conveyor. At first, it is introduction about the belt conveyor. Next, it is the principles about choose component parts of belt conveyor. After that the belt conveyor abase on the principle is designed. Then, it is checking computations about main component parts. The ordinary belt conveyor consists of six main parts: Drive Unit, Jib or Delivery End, Tail Ender Return End. Intermediate Structure, Loop Take-Up and Belt. At last, it is explanation about fix and safeguard of the belt conveyor. Today, long distance, high speed, low friction is the direction of belt conveyor’s development. Air cushion belt conveyor is one of them. At present, we still fall far short of abroad advanced technology in design, manufacture and using. Key words：conveyor belt；Transmission Drum ；Roller；Brakes；Bend device；tensioning device
