文档介绍：摘要
螺旋输送机是一种不具有挠性牵引构件的旋转类型的物料输送机械,是现代化生产和物流运输不可缺少的重要机械设备之一。它的广泛应用对于提高劳动生产率,实现物料输送过程的机械化和自动化,都具有重要的现实意义。
对于螺旋输送机,在工程设计及使用中还存在一些的缺陷,如参数选择不合理等。目前,螺旋输送机的设计仍是依靠经验公式计算,在经验公式中许多参数的选择是在一定范围内凭经验选取的,这使得螺旋输送机的设计较落后,无法提高其设计水平和提高产品的性能。
文中对螺旋输送机进行了较全面论述,了解了螺旋输送机的类型、发展现状。阐明了螺旋输送机的工作原理。并根据螺旋输送机的工作原理、工作条件、输送要求等设计一螺旋输送机。该螺旋输送机用于水泥的水平输送,根据输送量以及输送路程设计出螺旋直径,计算了螺旋功率以及根据功率选择了电动机、减速器和联轴器能较好地解决实际问题。
最后对螺旋输送机的安装及平时保养做出了总结。整个设计对今后的设计工作将有实际指导意义和价值。

Abstract
The screw conveyor is the necessary device of modern manufacturing and material fluid transportation. In order to reduce people's heavy physical work, to raise working productivity, to achieve material-conveying automation and mechanization, it possesses very important practical significance. It has already widely used in many country departments. Screw conveyors are used extensively in industry for conveying and elevating bulk materials over relatively short distances. They are very effective conveying devices for relatively free flowing bulk solids.
This es from an investigation practical problem, which is put forward during the institute of construction machinery research makes some surveys. In fact, for screw conveyors, there are many problems in design, use, engineering, such as configuration design, non-reasonable in parameters choice and not convenience of acting machines. Thus there is often defect when materials are conveyed, for example, materials jam, noise, power wastage. These problems need urgent settlements.
The text of the screw conveyor in a prehensive discussion about the type of screw conveyor, the development of the status quo. To clarify the working principle of the screw conveyor. Screw conveyor in accordance with the working principle, working conditions, transportation requirements to design a screw conveyor. The screw conveyor for conveying the level of cement, according to throughput and transmission distance diameter spiral design, computing power, as well as a spiral in accordance
