本科毕业设计说明书 下运带式输送机选型设计 THE LECTOTYPE DESIGN OF DOWNWARD BELT CONVEYOR 学院（部）： 机械工程学院 专业班级： 学生姓名： 指导教师： 2011 年 6 月 10 日 下运带式输送机选型设计 摘要 带式输送机是用于散料输送的重要设备之一，其结构简单，运行平稳可靠，能耗低，对环境污染少，便于控制和实现自动化，且管理维护方便在连续装载的情况下可实现连续运输，因此在国民经济各部门得到广泛的应用，特别是在煤炭生产和矿山运输中系统中，目前带式输送机正向长距离，大运量，高带速的方向发展，日趋大型化，复杂化，智能化。而下运带式输送机在煤炭采掘过程中也被经常用到，而且，下运时的控制因素往往比上运时的更为复杂，因此设计下运带式输送机能使学生运用大学所学知识，解决实际问题的能力得到大幅提升。[1] 本文便是矿用井上下运带式输送机的选型设计说明书。其与系统装配图以及零件图共同构成本次毕业设计的主要内容。该设计是以毕业设计为契机依照传统的带式输送机选型设计方法进行设计。第一章绪论中对带式输送机结构功能原理等进行了简单的介绍，以便使读者对带式输送机拥有一般性的认识。第二章则针对下运带式输送机的具体参数进行设计计算，具体说明本设计中各个参数的由来，从而为后面的选型设计以及整体设计提供坚实的理论基础，和精确的数据支持。第三章则根据前面的计算结果进行带式输送机零部件的选型校核，以确保设计中的各个部件选用的合理性，以及可靠性。然后进行总结并致谢，最后附上参考书目。 关键词：下运带式输送机，尼龙绳芯带，传动滚筒，重锤拉紧，选型设计  THE LECTOTYPE DESIGN OF DOWNWARD BELT CONVEYOR ABSTRACT The belt conveyor is one of the important equipment which is used in the transportation of bulk cargo. The advantage of the belt conveyor is simple structure smooth and reliable operation, low energy consumption, little pollution to the environment, easily control and easily to be automation, and can continuously transport in the continuous loading. So it has been widely used in the department of the national economy, especially in the production and transportation of the coal. Recently, it is developing to the long distance, large transportation quantity and high speed. It is become bigger and bigger, more and more complex and more and more intelligent. And the downward belt conveyor is often used in the coal mining work, and its control factor is often more complex than the upward belt conveyor, so the lectotype design of downward belt conveyor can let the ability that the student use the knowledge which is learned in the university to solve problem increase significantly. This essay is about the lectotype design of downward belt conveyor which is used in the mine on the ground. The manual, the assembly drawing and the part drawing are mad
