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/mi
n。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EBZ200型掘进机的检修及维护保养。 关键词:掘进机;截割部;齿轮减速器;带伸缩 Abstract The ca
