散装物料倾斜TDⅡ型固定式带式输送机设计 摘要 随着科学技术的发展，带式输送机的种类也逐步全面，由自动化程度低且工作效率低的带式输送机向工作效率高，自动化程度高的方向发展。在带式输送机的发展长河里，原始的带式输送机在操作方面需要大量的人力物力。现在，带式输送机的运用已经和其他学科的知识相结合，设计制造出在不同场合下适用的带式输送机，使其工作效率更高，节省大量物力劳力。 带式输送机作为连续运输机中的一种，其运输特点是形成装载点到装载点之间的连续物料流，靠连续物料流的整体运动来完成物流从装载点到卸载点的输送，应用非常广泛，主要运用在输送沙石、谷物、煤炭等散装物料。其优点有：1、工作效率高，短时间内连续不断运输很多物料；2、结构简单，零件便宜，工业成本降低了很多；3、应用广泛，涉及多个方面；4、适应环境强，在恶劣环境下也能稳定工作。 本次设计首先通过查询资料了解带式输送机的国内外发展现状，然后对固定式带式输送机的构造以及工作原理进行理论分析，并进行传动系统和结构的设计，最后通过设计和计算确定主要参数、主要零件的选用以及图纸的绘制，从而完成本次设计。 关键词：带式输送机；设计；计算；选型 ABSTRACT With the developme
