大倾角带式输送机设计 DESIGN OF LARGE DIP BELT CONVEYOR 摘要 随着科技的发展，大倾角输送机已在运输行业广泛使用起来。本篇简单介绍了带式输送机现状及国内外的技术差距，详细的说明了输送机的分类及特点，阐述了输送机的工作原理并设计出了一套可行性较高的总体方案，通过已给定的参数进行一系列的设计计算对输送机各个部件做出设计选型，完成整个机体的设计。大倾角带式输送机的基本部件均可与普通输送机通用，因此维修方便，而与通用带式输送机相比，大倾角带式输送机可以以0°～90°任意角度进行输送，这大大地减少了机器的占地面积也节约了工程投资的费用，为我国输送行业的发展做出了巨大地贡献。 关键词带式输送机；大倾角；滚筒 Abstract With the developme
