摘  要

回柱绞车是供煤矿井下采煤工作面回柱放顶的主要设备。由于它的高度较低、重量又轻，特别适用于薄煤层和急倾斜煤层采煤工作面，以及各种采煤工作面沉入底板或被矸石压埋的金属支柱的回收。随着机械化采煤程度的提高，它越来越多地被广泛用于机械化采煤工作面，作为安装、回收、牵引各种设备和备件之用。
目前，在回柱绞车的设计、制造以及应用上，国内与国外先进水平相比仍有较大差距。国内在设计制造回柱绞车过程中存在着一定程度上的缺点，重要的问题如：轮齿的根切、蜗杆毛坯的正确设计等。
这篇毕业设计的论文主要阐述的是一套回柱绞车传动部分的设计方法，主要包括蜗轮蜗杆减速装置、直齿圆柱齿轮传动、轴承和传动件的润滑系统，还包括制动装置的选用、一部分常见故障的分析以及日常的使用与维护等。

ABSTRACT
Prop-pulling hoist is for underground mines coal face of main equipment blasting down the roof. Because of its high and low weight light, especially suitable for thin coal seam and the mining face, and various kinds of coal gangue sink or buried by pressing the pillar of the metal recycling. With the increase of mining mechanization degree, it is more and more widely used in mechanization mining face, as installation, recycling of equipment and spare parts of the traction.
At present, in the design, manufacture, prop-pulling hoist and applications, the domestic and foreign advanced level compared to still have a large gap. In the design and manufacture of domestic prop-pulling hoist process, to a certain extent, the shortcomings of the important questions like: the root, the worm gear of blank design etc.
This paper mainly expounds the graduation design is a set of transmission part prop-pulling hoist the design methods, including worm gear and worm reducer device, spur gears, bearings and drive transmission lubrication, including the selection of brake and the common faults and daily use and maintenance, etc.
