JD—1.6吨型无极绳绞车设计 摘要 JD-1.6吨型无极绳绞车是一种新型的矿山辅助运输设备。其主要适用于煤矿井下长运距，多起伏的运输巷道，特别适用于大型综采设备的运输牵引和长运距矿车及材料的运输。能大大提高运输效率和运输安全可靠性，防止放打滑现象。该绞车的设计对于完善无极绳绞车起着重要的基础作用。 JD-1.6吨型无极绳绞车主要由电动机、联轴器、减速器、卷筒和制动闸等组成。本设计的重点是减速器的设计，该传动系统采用了三级传动，第一级为弧度齿圆锥齿轮传动，第二级为圆柱斜齿轮传动，第三级为圆柱直齿轮传动，传动原理简单、可靠、高效。 JD-1.6吨型无极绳绞车具有良好的防爆性能和制动性能，容绳量大、适用条件强、使用寿命长、传动效率高等特点。该绞车结构紧凑，外形尺寸小，能够整机下井；结构为近似对称布置，外形美观，成长条形，底座呈雪橇状；绞车重心低，底座刚性好，可安装地锚，运转平稳，安全可靠，维护方便。 关键词：无极绳绞车；运输；传动 ABSTRACT JD-1.6t-Promise ropewi
