1、题目：采煤机摇臂减速箱的设计专业：机械设计制造及其自动化学生：（签名）指导教师：（签名）摘要MG132/320-WD型采煤机是一种电牵引大功率采煤机，该机机身矮，装机功率大，所有电机横向布置，机械传动都是直齿传动，电机、行走箱驱动轮组件等均可从老塘侧抽出，故传动效率高，容易安装和维护。本说明书主要介绍了采煤机截割部的设计计算。MG132/320-WD型采煤机截割部主要是由四级齿轮传动组成，截割部电机放在摇臂内横向布置，电动机输出的动力经由三级直齿圆柱齿轮和一级行星轮系的传动，最后驱动滚筒旋转。截割部采用四行星单浮动结构，减小了结构尺寸，采用大角度弯摇臂设计，加大
2、了过煤空间，提高了装煤效果。在设计过程中，对截割部的轴、传动齿轮、轴承和联接用的花键等部件进行了设计计算、强度校核和选用。本说明书主要针对主要部件的设计计算和强度校核进行了叙述和介绍。此外，还对MG132/320-WD采煤机的使用与维护进行了说明，以便能更好的发挥该采煤机的性能，达到最佳工作效果。关键词：采煤机；截割部；行星轮系；齿轮传动设计77AbstractTheMG132/3200-WDtypeminingmachineisthatakindofelectricitydrawsthehigh-powerminingmachine,thismachinefu
