TDTG5024斗式提升機機頭及中間節(jié)設計

包括論文，整套cad圖紙和答辯ppt

摘    要

關鍵詞：1、TDTG50/24斗提機由機頭、機座、機筒、觀驗機筒、減壓機筒、畚斗、畚斗膠帶、傳動裝置等部分組成。
        2、機頭部件由機頭座、機頭蓋、頭輪、頭輪軸、軸承座、密封蓋等部分組成，機頭座上設有檢修窗及調整擋板。
        3、 中間節(jié)有三部分組成（1）觀驗檢修機筒（2）普通機筒（3）減壓機筒
（1）觀驗檢修機筒
觀驗檢修機筒設有檢修門，可以供觀驗和檢修之用，機筒由優(yōu)質鋼板折彎咬邊聯(lián)結，美觀，強度好，密封性能佳，上下端焊接法蘭，用于連接其他部件
（2）普通機筒   普通機筒沒有檢修門，其結構和觀驗機筒一樣
（3）減壓機筒    減壓機筒可以使物料空氣循環(huán)，機筒內壓力平衡，空氣流通更順暢。
       4、傳動裝置一般采用擺線針輪減速電動機通過皮帶傳動（或者聯(lián)軸器、及鏈輪傳動）帶動頭輪軸傳動，也可采用普通電動機通過皮帶傳動帶動懸掛式軸裝減速器，其減速器是套裝在頭輪軸的伸出端上。以上兩種傳動方式其電機（或減速電機）均應安裝在電機架上，當斗提機設計高度小于10米時也可以安裝在機座上。 

 
                               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.
