文档介绍：摘要
本次毕业设计是关于固定式带式输送机的设计,因其具有输送能力大、结构简单、投资费用相对较低及维护方便等特点而被广泛应用于港口、码头、冶金、热电厂、焦化厂、露天矿和煤矿井下的物料输送。本次毕业设计是关于矿用固定式带式输送机的设计。首先对胶带输送机作了简单的概述;接着分析了胶带输送机的选型原则及计算方法;然后根据这些设计准则与计算选型方法按照给定参数要求进行选型设计;接着对所选择的输送机各主要零部件进行了校核。普通型带式输送机由六个主要部件组成:传动装置,机尾或导回装置,中部机架,拉紧装置以及胶带。最后简单的说明了输送机的安装与维护。目前,胶带输送机正朝着长距离,高速度,低摩擦的方向发展,近年来出现的气垫式胶带输送机就是其中的一个。
本次带式输送机设计代表了设计的一般过程, 对今后的选型设计工作有一定的参考价值。

Abstract
The design is a graduation project about the belt conveyor. Because of its large transmission capacity, simple structure, relatively low investment costs and easy maintenance,it has been widely used in ports, docks, metallurgical, power plants, coking plants, open-pit coal mine and transportation of materials. The design is a graduation project about the belt conveyor used in coal mine. At first, it is introduction about the belt conveyor. Next, it is the principles about ponent parts of belt conveyor. After that the belt conveyor abase on the principle is designed. Then, it is putations about ponent 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.
There are a lot of wastes in the design of belt conveyor.
Key words: the belt conveyor Drive Unit Delivery End
