摘要
本次毕业设计是关于煤矿胶带输送机的总体设计及电动滚筒设计。在参考常规的上运式固定带式输送机设计方法的基础上,首先对胶带输送机作了简单的概述;然后根据设计准则与计算选型方法按照给定参数要求进行总体方案选型设计及数据计算;接着对所选择的输送机各主要零部件进行了校核,对电动滚筒做了详细的结构设计及校核计算。普通型带式输送机由六个主要部件组成:传动装置,机尾和导回装置,中部机架,拉紧装置以及胶带。最后简单的的提出了对带式输送机和电动滚筒的改进设计思想及方法。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。在胶带输送机的设计、制造以及应用方面,目前我相比仍有较大差距,国内在设计制造带式输送机过程中存在着很多不足。

Abstract
The design is a graduation project about the belt conveyor used in coal mine and electric roller. In reference to the conventional fixed conveyor transported the basis of design. At first, it is introduction about the belt conveyor. Next ,Then calculated in accordance with design criteria and selection methods to set parameters in accordance with the requirements of the overall program design and data , it is putations about ponent parts, the electric roller made a detailed calculation of the structural design and verification. 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 the belt conveyor and electric roller the improvement of design thinking and methods. 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. There are a lot of wastes in the design of belt conveyor.
