摘    要
      本設(shè)計(jì)的主要目的是：掌握一般機(jī)械產(chǎn)品設(shè)計(jì)的方法及規(guī)律；掌握橫軸式截割部的設(shè)計(jì)步驟。
本設(shè)計(jì)內(nèi)容為履帶式半煤巖掘進(jìn)機(jī)設(shè)計(jì)。在此，主要進(jìn)行了掘進(jìn)機(jī)的整體功能設(shè)計(jì)和掘進(jìn)部的結(jié)構(gòu)設(shè)計(jì)。在整體設(shè)計(jì)中，本設(shè)計(jì)主要對(duì)掘進(jìn)機(jī)的裝載系統(tǒng)、物料輸送系統(tǒng)、行走系統(tǒng)、液壓系統(tǒng)，以及機(jī)架和回轉(zhuǎn)臺(tái)等主要系統(tǒng)和部件進(jìn)行功能設(shè)計(jì)，確定其主要的功能參數(shù)。
本設(shè)計(jì)對(duì)掘進(jìn)部進(jìn)行了詳細(xì)的設(shè)計(jì)、計(jì)算。本掘進(jìn)機(jī)采用橫軸式掘進(jìn)部。在設(shè)計(jì)中，主要對(duì)掘進(jìn)部中的支撐架，掘進(jìn)部的減速器等進(jìn)行了詳細(xì)的設(shè)計(jì)、計(jì)算；對(duì)掘進(jìn)頭進(jìn)行了功能設(shè)計(jì)。本掘進(jìn)部設(shè)計(jì)的主要特點(diǎn)是：
 （1）用三級(jí)齒輪傳動(dòng)加惰輪的方式增加了掘進(jìn)部的長(zhǎng)度，滿(mǎn)足了掘進(jìn)部的長(zhǎng)度要求，并且避免了最后一級(jí)齒輪因直徑過(guò)大而和掘進(jìn)頭產(chǎn)生干涉。
   （2）第一級(jí)使用錐齒輪傳動(dòng)，滿(mǎn)足了橫軸式掘進(jìn)部需要改變傳動(dòng)方向的要求。
    此外，本設(shè)計(jì)還對(duì)半煤巖掘進(jìn)機(jī)的特點(diǎn)和發(fā)展概況進(jìn)行了簡(jiǎn)單介紹，對(duì)掘進(jìn)機(jī)拆運(yùn)安裝和調(diào)整，掘進(jìn)機(jī)的井下組裝以及掘進(jìn)機(jī)的檢修和維護(hù)保養(yǎng)作了簡(jiǎn)單介紹。

ABSTRACT
        The main purposes for this design are as follows: to know how to design a digging machine ;to master the way to design the crossing axis digging part of the digging machine.
The thing of this design is a digging machine which is used to cut coal and movd by chain，this design mainly about the function of all of the parts of the machine and the structure of the digging part. In the design of of the whole machine ,this article is main about the taking system ,the carring system ,the walking system ,the liquid system and the the machine structure and so on .
This article mainly talk about the structure of the digging part ,this digging part is a crossing axis digging part.In this article ,the structure of the sustain shelf and the the speed reducing machinery are carefully designed.the characteristic of the digging part are as follows:
  (1) Three couple of gears are used in the speed reducing machinery to add the lengh of the digging part and because this way of design ,the intervention of the gear and the digging head can be avoid.
(2) The cone gears are used in the first couple of the gears,it fulfil the need of the aspect changing of the digging part.
Furthermore the article also talks about the digging machine’s earmark and the history of the digging machine ,and this article also talks about the dismantling and fixing of the machine,the checking and repairing of the machine.

Keywords：
digging machine ; digging part ; speed reducing machinery.
