摘   要

     MG400/920-WD型采煤機是一種電牽引大功率采煤機，該機機身矮，裝機功率大，所有電機橫向布置，機械傳動都是直齒傳動，電機、行走箱驅動輪組件等均可從老塘側抽出，故傳動效率高，容易安裝和維護。
 本說明書主要介紹了采煤機截割部的設計計算。MG400/920-WD 型采煤機截割部主要是由四級齒輪傳動組成，截割部電機放在搖臂內橫向布置，電動機輸出的動力經由三級直齒圓柱齒輪和一級行星輪系的傳動，最后驅動滾筒旋轉。截割部采用四行星單浮動結構，減小了結構尺寸，采用大角度彎搖臂設計，加大了過煤空間，提高了裝煤效果。
 在設計過程中，對截割部的軸、傳動齒輪、軸承和聯接用的花鍵等部件進行了設計計算、強度校核和選用。本說明書主要針對主要部件的設計計算和強度校核進行了敘述和介紹。
 此外，還對MG400/920-WD采煤機的使用與維護進行了說明，以便能更好的發揮該采煤機的性能，達到最佳工作效果。
關鍵詞：采煤機；截割部；行星輪系；齒輪傳動設計

ABSTRACT

    The MG400/920-WD 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 moderate breeze gear wheel transmission that the MG400/920-WD 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 MG400/920-WD 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.
 Keyword: Mining machine ；the cutting department ； A department of planet ；Gear wheel of the transmission Design
