槽形托辊带式输送机

槽形托辊带式输送机设计

摘要：本文中概述了带式输送机的应用范围，分析了其工作原理和主要性能。对带式输送机的各个组成部件进行了详细的分析和选用。在设计中对输送机的主要部件进行了受力计算。并用Solidworks对连接轴进行有限元分析，使其强度达到要求。其后还对输送机的主要部件的作了寿命分析。
本文所设计的是槽形托辊带式输送机，其设计要求为：输送物料为原煤，输送量：80 吨/小时，输送长度：30 米,提升高度2米；堆积密度：900公斤/米3；物料在带面上的动堆积角为 ，输送带速：1.2米/秒，上托辊槽形布置。设计中，其整体是一个倾斜的状态，上托辊都采用槽形布置；下（回程）托辊采用平行托辊。本输送机为向下运输物料，其倾斜角为3.80<150，所以采用小倾角设计。在设计带宽时，按照槽形布置来选择计算。在尾架的选取方面，采用螺旋拉紧装置尾架，使输送带能始终保持必要的张力。用Solidworks对连接轴进行有限元分析，得出其一般工作时的性能状态，并做出相应的调整。

Abstract: This paper provides an overview of the scope of application of belt conveyor, an analysis of its working principle and main performance. The detailed analysis and selection are carried out on the various components of the conveyor components. In the design of the conveyor of the main components of the stress is calculated. In the design bandwidth, the calculation is carried out in accordance with the layout. And Solidworks is used to do the finite element analysis on the connecting axis. Subsequently it also analysis the main conveyor components’ life.
What is designed in this paper is slotted roller belt conveyor, the design requirements are: transport of materials: coal, transport capacity: 80 tons / hour, transmission length: 30 meters, 2 meters high upgrade Bulk Density: 900 kg / m3 materials in the dynamic accumulation of the surface with angle, conveyor speed: 1.2 m / s, on the trough roller arrangement. Design of a tilt the overall state of the idler trough arrangement used under the (return) the use of parallel idler rollers. When the materials are transport down through the conveyor, the tilt angle is 3.80 <150, so take the use of small-angle design. As the selection of the tailstock, we take the use of Tailstock screw tensioning device so that the conveyor system can always maintain the necessary tension. And Solidworks is used to do the finite element analysis on the connecting axis, to meet the required strength. [版权所有：http://think58.com]
