1、毕业设计（论文）题 目： 水平带式输送机设计 专 业： 机电一体化 班 次： 05415 -46 姓 名： 朱晓锋 指导老师： 李刚俊 成都电子机械高等专科学校 二OO八年六月 42 成都电子机械高等专科学校毕业论文 作者：战胜涛摘 要输送机械又称连续输送机械，它是沿着一定的输送路线运输货物的机械。在现代化的大企业中，有大量的原料、半成品和成品（如矿石、焦炭、耐火材料、水泥、化肥、建筑材料、谷物等）需要机械搬运，除了起重机械搬送一部分可以装箱或堆垛的大件物品外，大量的粒散料和小件物品的运输，是靠各种形式的运输机来完成的，在有些工艺流程中，运输机械还是必不可少的生产机械。运输机械的形式很多，本设
2、计为输送机械的第一类，即固定式带式输送机的设计。带式输送机是用连续运动的无端输送带输送货物的机械。随着全球经济的增长，带式输送机技术已成为当代科学技术发展的前沿之一。当今世界需要设计和生产“环保”型输送机，要求输送量超过10000th，并且要节约能量。输送机技术进步的一个重要特点是基础研究发展为应用技术，进而实现商业化。带式输送机是用途最为广泛的一种运输机械。主要应用在沿水平方向或沿坡度不大的倾斜方向，连续的大批量地运送粒散状物料或单件物品。它具有生产率高、运送距离长、工作平稳、结构简单、可以在任意位置上装卸、自重小、工作可靠、操作简便、耗能少等重要优点。在本文中，详细地根据要求对带式输送机的
3、全部过程进行了设计和计算，即总体设计计算、各部件的设计选用，并绘制了总装图及其主要部件的零件图。关键词 输送机械 固定式 带式输送机 Abstract Transport machine is called the consecution transports machine, it is a machine which conveyances goods along certainly transport route .In modern big business enterprise, there are a great deal of raw material, semi-process
