摘要
刮板输送机是矿山运输机械的重要组成部分，作为具有挠性牵引力的连续输送机械，它被广泛用作采煤工作面和煤巷的运输工具。在此设计中，对组成刮板输送机的部件结构进行分析和计算，并着重设计了减速器等部件的结构。刮板输送机的动力装置采用防爆异步电动机，减速器使用自行设计的三级锥齿轮减速器。机头链轮是由电动机通过液力耦合器与减速器连接传动到的，从动力部分开始传动，从而带动下一级的传动，一级带着一级，在这段工作的时间内刮板运动是重复的，从而物料循环的完成任务。刮板输送机在矿井下相当于领导者地位，它可以代替工人在矿井下工作。这样不仅可以保证了工人的安全，还大大提高了相比较人工而言缓慢的工作效率，效率一提高带给公司的就是很直接的利益。因此，对刮板输送机进行更深层次的研究和改进对煤炭工业的发展是非常有必要的，对时代文明的快速进步有非凡意义。

Abstract

The scraper conveyor is an important part of the mine transportation machinery. As a continuous conveying machine with flexible traction force, it is widely used as a transportation tool for coal mining face and coal roadway. In this design, the component structure of scraper conveyor is analyzed and calculated, and the structure of reducer and other components is emphatically designed. The power unit of scraper conveyor adopts explosion-proof asynchronous motor, and the reducer uses a self designed three stage bevel gear reducer. The head sprocket is driven by the motor through the hydraulic coupler and the reducer, starting from the power part, thus driving the next level, and the first level with the first level. In this period, the scraper movement is repeated, thus the material circulation is completed. The scraper conveyor is equal to the leader position under the mine, it can replace the worker to work under the mine. This can not only guarantee the safety of the workers, but also greatly improve the efficiency of the slow work in comparison with the manual, and the efficiency is directly beneficial to the company. Therefore, the further research and improvement of the scraper conveyor is very necessary for the development of the coal industry, and it is of great significance to the rapid progress of the times civilization.
