【正文】 CA6140 車床主軸箱傳動系統(tǒng)設(shè)計(jì)及仿真 摘要 :CA6140 臥式車床屬于通用的中型機(jī)床，其主要組成部分可概括為“三箱刀架尾座床身”。此畢業(yè)設(shè)計(jì)是對 CA6140 車床主軸箱的傳動系統(tǒng)及仿真進(jìn)行設(shè)計(jì)，設(shè)計(jì)的內(nèi)容包括：主傳動系統(tǒng)總體設(shè)計(jì)、機(jī)床主軸箱設(shè)計(jì)傳動設(shè)計(jì)、動力計(jì)算。主傳動系統(tǒng)總體設(shè)計(jì)包括主傳動形式選擇、主軸電機(jī)選擇及功率計(jì)算；機(jī)床主軸箱設(shè)計(jì)傳動設(shè)計(jì) :擬定主傳動參數(shù)、結(jié)構(gòu)網(wǎng)、轉(zhuǎn)速圖、確定齒輪齒數(shù)和帶輪直徑，主傳動的轉(zhuǎn)向與制動方式，畫出主運(yùn)動的傳動系統(tǒng)圖；動力計(jì)算，其中包括確定齒輪模數(shù)，軸的尺、軸承的形式和型號， 以及其他有關(guān)的計(jì)算。我運(yùn)用 CAD 完成了主軸箱的二維總裝配圖和幾個軸上零件的裝配圖，運(yùn)用 ProE 軟件完成零件設(shè)計(jì) (軸、齒輪、箱體、軸承等并進(jìn)行了虛擬裝配和仿真，保存了仿真的視頻格式并且在 界面中讓它運(yùn)行起來。 關(guān)鍵詞 ： CA6140 機(jī)床 。主軸箱 。零件傳動 Design and Simulation of CA6140 lathe main spindle box drive system Abstract:CA6140 lathe is a versatile mediumsized bedrooms machine, the main ponents can be summarized as threebox turret tailstock bed. This graduation project is a drive system and simulation CA6140 lathe headstock design, the design includes: overall design of the main drive system, the spindle box design transmission design, dynamic calculation. The overall design of main drive system includes a main form of transmission choice, selection and spindle motor power calculation。 spindle box design transmission design: Preparation of the main transmission parameters, work structure, speed diagram, determine the diameter of the pulley and gear, main drive and steering system dynamic way, to draw the main motion drive system diagram。 dynamic calculation, including the identification of the gear module, feet, bearing forms and models, as well as other relevant calculation axis. I use CAD finished headstock assembly drawing twodimensional assembly drawing and parts of several axes, the use of ProE design software to plete parts (shafts, gears, box, bearings and virtual assembly simulation and save simulation video formats and let the interface up and running.
