摘   要

     斗轮堆取料机是一种高效率的连续装卸设备，被广泛应用在火电厂、港口码头、钢铁冶金、矿山、建材水泥、化工、煤炭与焦化厂等原料储运场，可实现煤炭、矿石、化工原料等散状物料的堆取、转运、装卸的连续作业。
带式输送机是斗轮堆取料机中重要环节,在其它方面也广泛应用。带式输送机是现代物料连续运输的重要设备，是连续运动的无端输送带运送货物的机械，用胶带作为输送带的带式输送机称为胶带输送机，简称胶带机。它具有结构简单、成本低、运输距离长、效率高的优点。其主要用于冶金、采矿、煤炭、电站、港口以及工业企业。它将为我国各矿业装卸工作的机械化、现代化作出越来越大的贡献。
本文主要介绍了斗轮堆取料机中的运输皮带机。首先，介绍了带式输送机的工作特点、发展概况、工作原理，分类；其次，介绍了胶带的摩擦传动原理；最后，根据带式输送机的工作条件对其计算，其中对传动部分的减速器部分进行了详细的设计及设计计算，简单分析了皮带跑偏及撒料的原因和解决方法，又介绍了其他几种形式的皮带机。

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
