毕 业 设 计学校： 榆 林 学 院课题： 矿用固定带式输送机 专业： 机械设计制造及其自动化 班级： 09 级机械（2）班姓名： 陈 向 龙学号： 0905220226 摘 要矿用带式输送机作为我本次的毕业设计。首先查看相关文献，对矿用带式输送机的设计有一个总体的认识：首先，我们要了解矿用带式输送机的结构原理、应用及种类；接下来，我们进行了矿用带式输送机的系统设计；下一步，我们进行矿用带式输送机的计算包括（输送量与带速、稳定工况下的运行阻力和功率的消耗、驱动系统的设计、输送带的张紧力、输送带的抗拉强度和覆盖层的选择以及滚筒的最小直径）；再者，我们要进行对矿用带式输送机的主要零部件设计计算，六个主要组成部分：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，我们对矿用带式输送机的计算理论等相关设计计算，以及矿用带式输送机的安装与维护；以上，就是我对本次矿用带式输送机设计的一般方法过程； 关键词：矿用带式输送机；设计准则，计算方法；AbstractThe 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 choose component parts of belt conveyor. After that the belt conveyor abase on the principle is designed. Then, it is checking computations about main component 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. 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.
