皮带输送机-毕业设计参考Belt conveyor is the main component which is used to carry goods continued nowadays. With the development of the industry and technology, adopting to lager-amount long-length high –speed, the design method of large belt conveyor which is used to carry goods continued has been mostly studied. According to the belt conveyor drive principle, the paper uses point by point method to have a design, and with the given facts, magnize the model chose drive installment、roller roll belt pulling hydraulic. The drive installment adopts the advanced hydraulic soft drive system and hydraulic pull automatic system.Belt conveyor is the most ideal efficient coal for transport equipment, and other transport equipment, not only has compared long-distance large-capacity, continuous conveying wait for an advantage, and reliable operation, easy to realize automation, centralized control, especially for high yield and high efficiency mine, belt conveyor has become coal high-efficient exploitation mechatronics technology and equipment the key equipment.

前言
矿井开采是整个国家乃至世界的工业基础,而其产品运输又是最重要的工序之-,它的成本直接关系到工业各部门。所以,世界各国都在不断的改革矿井运输问题。大型矿井采用的运输方式有自卸汽车运输、铁路运输和胶带运送及运输等。其中,胶带运送机运输可谓是目前最先进的矿井开采新工艺。本次设计的主要内容即胶带输送机。
胶带输送机是现代散状物料连续运输的主要设备。越来越多的工程技术人员对胶带机的设计方法进行了大量的研究。我们将以经济、可靠、维护方便为出发点,对胶带机进行设计计算,并根据计算数据对驱动装置、托辊、滚筒、输送带、拉进装置以及其他辅助装置进行严格选型。
由于带式输送机的结构特点决定了其具有优良性能,主要表现在:运输能力大,且工作阻力小,耗电量低,约为刮板输送机的1/3到1/5;由于物料同输送机-起移动,同刮板输送机比较,物料破碎率小;带式输送机的单机运距可以很长,与刮板输送机比较,在同样运输能力及运距条件下,其所需设备台数少,转载环节少,节省设备和人员,并且维护比较简单。由于输送带成本高且易损坏,故与其它设备比较,初期投资高。
输送机年工作时间-般取4500-5500小时。当二班工作和输送剥离物,且输送环节较多,宜取下限;当三班工作和输送环节少的矿石输送,并有储仓时,取上限为宜。
电动机通过联轴器、减速器带动传动滚筒转动或其他驱动机构,借助于滚筒或其他驱动机构与输送带之间的摩擦力使输送带运
