摘要

MG200/456-AWD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。MG200/456-AWD 型采煤机截割部主要是由一个减速箱和四级齿轮传动组成，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拄齿轮和行星轮系的传动，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MG200/456-AWD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。

ABSTRACT

The MG200/456-AWD type mining machine is that a kind of electricity draws the high-power mining machine, this machine fuselage is low, Installation is large in power,all electrical machineries are fixed up horizontally, mechanical drive is all the transmission of straight tooth, electrical machinery, walk case drive wheel package etc. can take from old pool side out, so the transmission is high in efficiency, easy to install and safeguard.
Calculate in design which cuts the cutting department of main introduction mining machine of this manual. It is made up of a gearbox and moderate breeze gear wheel transmission that the MG200/456-AWD type mining machine cuts the cutting department, cut the electrical machinery of cutting department and put to fix up horizontally in the rocker arm, the power that the motor outputs leans on a round of transmission of department of gear wheel and planet round via the tertiary straight tooth, urge the cylinder to rotate finally. Cut the cutting department and adopt the floating structure of four planetary forms, have reduced the physical dimension, adopt the large angle to curve the rocker arm to design, have strengthened the space of coal, have improved the coal result of putting.
In the course of designing, to cutting the axle of the cutting department, gear wheel of the transmission, parts such as the bearing and spline linking using,etc have designed to calculate, the intensity is checked and selected for use. This manual mainly designs for main part one calculating to check with the intensity have narrated and introduced.
In addition，returning use for MG200/456-AWD mining machine and maintenance proves,In order to be able to good full play performance of person who should mine, reach the best working result.
