矿用200KW悬臂式掘进机截割部设计
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。
本次设计主要对掘进截割部结构进行了设计,截割部由电机、减速器、伸缩部、截割头四部分构成,其传动方式为电机输出轴通过联轴器将转矩传递给减速器的输入轴,减速器输出轴通过联轴器将转矩传递给主轴,主轴带动截割头转动。
在可截割硬度为80Mpa的基础上,对传动系统进行了选型以及方案设计,选用YBUD-200隔爆电动机、二级行星减速器、内伸缩式伸缩臂和圆锥形截割头,其中电机输出转速为1475r/mi
n,截割头截割转速为47.5r/mi
n。我主要对二级行星减速器和伸缩臂做了详细的结构设计,参照同类型掘进机的参数对其他部分做了设计。 关键词:EBZ200掘进机;截割部;齿轮减速器;带伸缩 Desig
