堆取料機皮帶機設(shè)計


摘  要

斗輪堆取料機是一種高效率的連續(xù)裝卸設(shè)備，被廣泛應(yīng)用在火電廠、港口碼頭、鋼鐵冶金、礦山、建材水泥、化工、煤炭與焦化廠等原料儲運場，可實現(xiàn)煤炭、礦石、化工原料等散狀物料的堆取、轉(zhuǎn)運、裝卸的連續(xù)作業(yè)。
帶式輸送機是斗輪堆取料機中重要環(huán)節(jié),在其它方面也廣泛應(yīng)用。帶式輸送機是現(xiàn)代物料連續(xù)運輸?shù)闹匾O(shè)備，是連續(xù)運動的無端輸送帶運送貨物的機械，用膠帶作為輸送帶的帶式輸送機稱為膠帶輸送機，簡稱膠帶機。它具有結(jié)構(gòu)簡單、成本低、運輸距離長、效率高的優(yōu)點。其主要用于冶金、采礦、煤炭、電站、港口以及工業(yè)企業(yè)。它將為我國各礦業(yè)裝卸工作的機械化、現(xiàn)代化作出越來越大的貢獻。
本文主要介紹了斗輪堆取料機中的運輸皮帶機。首先，介紹了帶式輸送機的工作特點、發(fā)展概況、工作原理，分類；其次，介紹了膠帶的摩擦傳動原理；最后，根據(jù)帶式輸送機的工作條件對其計算，其中對傳動部分的減速器部分進行了詳細的設(shè)計及設(shè)計計算，簡單分析了皮帶跑偏及撒料的原因和解決方法，又介紹了其他幾種形式的皮帶機。

Abstract

 Bucket Wheel Stacker and feeder is a highly efficient for handling equipment, is widely used in thermal power plants, port, iron and steel metallurgy, mining, cement building materials, chemicals, coal and coke plant, and other raw materials storage and transportation field, can be realized coal, ore , Chemical raw materials and other bulk material from the reactor, transit, handling of the continuum.
 Belt conveying systems is expected bucket Stacker and an important link in the machine, in other areas also widely used. Modern belt conveyor is an important material for transport equipment, is no reason for the movement of mechanical conveyor belt transporting goods, with the belt conveyor belt as a conveyor belt known as the conveyor belt, or tape machines. It is simple in structure, low cost, long distance transport, high efficiency advantages. Its mainly used for metallurgical, mining, coal, power plants, ports and industrial enterprises. It is China's handling of the mining mechanization and modernization of increasing the contribution.
 This paper presents a bucket Stacker and feeder in the transport belt machine. First of all, the work on the belt conveyor characteristics, Development, principle, classification and secondly, the friction on the tape drive principle; Finally, the working conditions under their belt conveyors, including the transmission of the slowdown Is part of a detailed design and design calculations, the simple analysis of the belt material deviation and spread the causes and solutions, has introduced several other forms of belt machine.
Key words: belt conveyors: Belt conveying systems ;Development survey; reduction gear
