SGZ730-400刮板输送机设计.doc

1、摘 要刮板输送机是一种挠性牵引的连续输送机械，是为了采煤工作面和采区巷道运煤布置的机械。它的牵引构件是刮板链，承载装置是中部槽，刮板链安置在中部槽的槽面。中部槽沿运输线路全线铺设，刮板链绕经机头，机尾的链轮接成封闭形置于中部槽中，与滚筒采煤机和输送机推移装置配套，实现落煤、装煤、运煤以及推移输送机械化。沿输送机全长都可向溜槽中装煤，装入中部槽中的煤被刮板链拖拉，在中部槽内滑行到卸载端卸下。用刮板输送机运送散碎物料的方式20世纪初出现于工业发达的英国。早期的刮板输送机结构简单轻便，仅用作运煤，需人工装煤，运输能力低，每小时最多只能运几十吨；输送机长度只有几十米；功率小，牵引链的强度也不高。经过多

2、年的改进和发展，目前综采矿用的刮板输送机除了运煤之外，还有四种功能：给采煤机作运行轨道；为拉移液压支架作伸缩油缸的固定点；清理工作面的浮煤；悬挂电缆、水管、乳化液管等。本说明书主要介绍了输送机传动部的设计计算。SGZ730/400型输送机传动部主要是由一个电动机、减速箱和液力偶合器组成，该输送机内横向布置，电动机输出的动力经由三级传动的圆锥圆柱齿轮减速速器传动。在设计过程中，对传动部的轴、传动齿轮、轴承和联接用的花键等部件进行了设计计算、强度校核和选用。本说明书主要针对主要部件的设计计算和强度校核进行了叙述和介绍。关键词：连续运输； 刮板链； 减速器； 设计AbstractConveyor i
