包括論文，整套cad圖紙和答辯ppt

摘    要

關(guān)鍵詞：1、TDTG50/24斗提機(jī)由機(jī)頭、機(jī)座、機(jī)筒、觀(guān)驗(yàn)機(jī)筒、減壓機(jī)筒、畚斗、畚斗膠帶、傳動(dòng)裝置等部分組成。
        2、機(jī)頭部件由機(jī)頭座、機(jī)頭蓋、頭輪、頭輪軸、軸承座、密封蓋等部分組成，機(jī)頭座上設(shè)有檢修窗及調(diào)整擋板。
        3、 中間節(jié)有三部分組成（1）觀(guān)驗(yàn)檢修機(jī)筒（2）普通機(jī)筒（3）減壓機(jī)筒
（1）觀(guān)驗(yàn)檢修機(jī)筒
觀(guān)驗(yàn)檢修機(jī)筒設(shè)有檢修門(mén)，可以供觀(guān)驗(yàn)和檢修之用，機(jī)筒由優(yōu)質(zhì)鋼板折彎咬邊聯(lián)結(jié)，美觀(guān)，強(qiáng)度好，密封性能佳，上下端焊接法蘭，用于連接其他部件
（2）普通機(jī)筒   普通機(jī)筒沒(méi)有檢修門(mén)，其結(jié)構(gòu)和觀(guān)驗(yàn)機(jī)筒一樣
（3）減壓機(jī)筒    減壓機(jī)筒可以使物料空氣循環(huán)，機(jī)筒內(nèi)壓力平衡，空氣流通更順暢。
       4、傳動(dòng)裝置一般采用擺線(xiàn)針輪減速電動(dòng)機(jī)通過(guò)皮帶傳動(dòng)（或者聯(lián)軸器、及鏈輪傳動(dòng)）帶動(dòng)頭輪軸傳動(dòng)，也可采用普通電動(dòng)機(jī)通過(guò)皮帶傳動(dòng)帶動(dòng)懸掛式軸裝減速器，其減速器是套裝在頭輪軸的伸出端上。以上兩種傳動(dòng)方式其電機(jī)（或減速電機(jī)）均應(yīng)安裝在電機(jī)架上，當(dāng)斗提機(jī)設(shè)計(jì)高度小于10米時(shí)也可以安裝在機(jī)座上。 

 
                               Abstract
   The lifting machine is one of the large-scale regular machine,used in the rise or fall and transport of various kinds of heavy objects. The small-scale lifting machine plays an important role too in daily life. TDTG50/24 lifting machine is made up of the head ,the middle one and motor,decelerator.It links by the shafts.The motor is the power source,the decelerator is a transmission,the cylinder,in order to carry out and control some,among then,the design of each part
   The head one is made up by  the basic segment , the hat ,the pulley ,the head shaft,and the bearing .There are some parts in order to check  the lifting machine .
   The middle parts are used to check the machine.There are three segments,including the cylinder.one,the checking one,and  the common one .
   The  cylinder one is made up by the window,which is used to watch and check the lifting machine.It looks very nice,and the force is enough.
  The common  one  dose not have the check one,and it looks like the above one .The part which lets down the press.It can make the air as a cycle .
The motor usually takes a decelerator..(the flexible coupling and the transport).It works by the shaft or by the common motor and decelerator .Both of  the two motors(or  decelerator)should put at the fixture,if the height is less 10 m  it also could put at the basic floor part of  the lifting machine .
  Key words:the lift machine, the decelerator ,TDTG50/24.
