EBZ160掘进机截割部设计摘要悬臂式掘进机是为煤矿综采及高档普采工作面采掘巷道的机械设备,它结构紧凑、适应性好机身矮、重心低、操作简单、检修方便。
本次设计主要是悬臂式掘进机的截割机构,悬臂式掘进机的截割机构是有伸缩式和固定式两种,按照它的截割头的分布可以分为横轴式和纵轴式两种。
我所设计的掘进机截割部是纵轴式带伸缩的形式。
纵轴式与横轴式相比,主要有结构简单,设计方便,便于安装和调试。
在截割过程中,横轴式可以进行上下左右摆动截割,方便灵活。
带伸缩的截割臂,在解决掘进机掘进面窄的问题上发挥了很大作用,掘进机截割部带伸缩,加大了截割部的长度,从而加大了截割头所经过的截割面,提高了掘进效率。
我的设计中动力源是电动机,通过联轴器传动,由减速器进行减速,最后输出转速为40r/min。
本设计中主要的传动结构为三级行星齿轮减速器,它包含了一级直齿轮传动和两级行星齿轮传动,输入和输出都采用花键联结。
本设计中介绍了EBZ160型掘进机的检修及维护保养。

This design mainly is the cantilever mechanical boring machine cutting organization, the cantilever mechanical boring machine cutting organization has extension and the stationary two kinds, may divide into the abscissa axis type and the ordinate axis type two kinds according to its cutting head distribution. I design mechanical boring machine cutting department is the form which the ordinate axis type belt expands and contracts. The ordinate axis type and the abscissa axis type compare, mainly has the structure to be simple, the design is convenient, is advantageous for the installment and the debugging. About the cutting process, the abscissa axis type may carry on about swings cutting, facilitates nimbly. The belt expands and contracts the cutting arm, played the very major role in the solution mechanical boring machine tunneling surface narrow question, the mechanical boring machine cutting department belt expanded and contracted, has increased the cutting department length, thus has enlarged the cutting surface which a cutting institute passed through, enhanced the tunneling efficiency. In my design the power supply is an electric motor, through the shaft coupling transmission, carries on by the reduction gear decelerates, the final output rotational speed is 40r/min. The design of the three-tier structure as the main transmission planetary gear reducer, which includes level straight gear transmission planetary gear transmission and levels, import and export are used spline up. The design introduced EBZ160 type boring machine overhaul and maintenance.Key word:Mechanical boring machine; Cutting department; Speed reducer gear; Belt expansion and contraction.目录1. 掘进机的概述 (1)1.1 悬臂式掘进机简介 (1).................................................................1.3 国外掘进设备及综掘技术发展现状1.4我国内掘进设备的发展及存在的问题.........................1.4.1 我国悬臂式掘进机的科研成果..........................1.4.2 我国悬臂式掘进机技术发展展望........................1.4.3 我国掘进机目前存在的问题............................ ................................................................. 悬臂式掘进机的基本组成...........................................悬臂式掘进机技术特点......................................2.EBZ160掘进机总体方案设计 (6)2.1 任务说明 (6)2.1.1 题目 (6)2.1.2 课题概况 (6)具体要求 (6)2.1.4 毕业设计工作量 (6)2.1.5 完成时间 (6)2.1.6 提交内容 (7)2.2 主要性能 (7)2.3 主要特点 (7)2.4 主要技术参数 (8)方案的确定 (8)2.5.1 工作机构的型式选择 (9)装载机构的型式选择 (9)工作机构的型式选择 (11)2.7除尘装置的型式选择 (11)2.8高压水细射流辅助切割技术123.
