摘要 本次畢業(yè)設(shè)計是關(guān)于DTⅡ型固定式帶式輸送機的設(shè)計。首先對膠帶輸送機作了簡單的概述；接著分析了膠帶輸送機的選型原則及計算方法；然后根據(jù)這些設(shè)計準則與計算選型方法按照給定參數(shù)要求進行選型設(shè)計；接著對所選擇的輸送機各主要零部件進行了校核。普通型帶式輸送機由六個主要部件組成：傳動裝置，機尾或?qū)Щ匮b置，中部機架，拉緊裝置以及膠帶。最后簡單的說明了輸送機的安裝與維護。目前，膠帶輸送機正朝著長距離，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就是其中的一個。在膠帶輸送機的設(shè)計、制造以及應(yīng)用方面,目前我國與國外先進水平相比仍有較大差距,國內(nèi)在設(shè)計制造帶式輸送機過程中存在著很多不足。 關(guān)鍵詞：輸送帶；傳動滾筒；托輥；制動裝置；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
