文档介绍：摘要
长距离、大运量、高速是带式输送机的最新发展方向。与其它输送设备相比,带式输送机运行更可靠,易于实现自动化和集中控制,经济效益十分明显。大倾角挡边带式输送机就是其中的一个。而覆带式挡边带式输送机更是弥补了普通挡边机所存在的不足之处。
本文首先对普通带式输送机的运用、分类、特点、原理作了简单地概述,接着阐述了大倾角挡边机的技术优势,引出本次设计-覆带式挡边带式输送机的设计意义;然后对整机的设计方案进行比较选择,在传动方案方面,本文选取了3种传动方式进行比较,选出最经济、实用的一种方式,对驱动装置的每个部件进行了较为详细的描述,然后做出选择;接着对设计中所需要的数据进行设计计算,再根据设计准则与计算选型方法按照给定参数要求,对输送机的传动装置、改向装置、拉紧装置、中部机架、托辊、清扫装置等进行选型设计;接着对输送机的传动滚筒轴等主要零部件进行了强度校核;最后简单地说明了输送机的电气及安全保护装置。

Abstract
Long distance,large capacity,high speed is the latest development in the direction of the belt pared with other transportation equipments,belt conveyor is more reliable,easier to implement automation and centralized control,more obvious economic sidewall belt conveyor is one of ,the cover sidewall belt conveyor makes up for ings that ordinary sidewall unit exists.
Firstly,the design outlines briefly the use,classification,characteristics,principles mon belt conveyor and then it describes technological advantages of the steep wall machine and it leads to this design-cover sidewall belt conveyor and what it pares and chooses the whole machine’s transmission mode,the pares 5 kinds of transmission mode to select the most economical and practical way,then ponent is given a more detailed description and then the paper chooses the best that it designs and caculates the data needed,tensioning device,the central rack,roller,cleaning devices according to the design criteria and selection method in accordance with the requirments of the given ,it is the strength check of drive roller shaft,and other last,it is brief description of the electrical safety devices.
Key words:belt conveyor;program design;parts selection;design caculations
