C6132普通車床主傳動系統(tǒng)設(shè)計(jì)說明書


摘要

主傳動系統(tǒng)設(shè)計(jì)是機(jī)床設(shè)計(jì)中非常重要的組成部分，本次設(shè)計(jì)主要由機(jī)床的級數(shù)入手，于結(jié)構(gòu)式、結(jié)構(gòu)網(wǎng)擬定，再到齒輪和軸的設(shè)計(jì)，再選擇各種主傳動配合件，對軸和齒輪及配合件進(jìn)行校核，將主傳動方案“結(jié)構(gòu)化”，設(shè)計(jì)主軸變速箱裝配圖及零件圖，側(cè)重進(jìn)行傳動軸組件、主軸組件、變速機(jī)構(gòu)、箱體、潤滑與密封、傳動軸及滑移齒輪零件的設(shè)計(jì)，完成設(shè)計(jì)任務(wù)。
本次突出了結(jié)構(gòu)設(shè)計(jì)的要求，在保證機(jī)床的基本要求下，根據(jù)機(jī)床設(shè)計(jì)的原則，擬定機(jī)構(gòu)式和結(jié)構(gòu)網(wǎng)，對機(jī)床的機(jī)構(gòu)進(jìn)行精簡，力求降低生產(chǎn)成本；主軸和齒輪設(shè)計(jì)在滿足強(qiáng)度需要的同時(shí)，材料的選擇也是采用折中的原則，沒有選擇過高強(qiáng)度的材料從而造成浪費(fèi)。
【關(guān)鍵詞】車床、主傳動系統(tǒng)、結(jié)構(gòu)式、電動機(jī)。

Abstract
    Main drive system design is Very important part of the Machine Design,The design of the series to start primarily by machine,In the structure, the structure network developed, to the design of gears and shafts,Choose a variety of main drive with the pieces of the shaft and gear, and checked with the parts ，design and motive of completion sport spread the lord to move the project"the structure turn" , Design a principal axis to become soon a box assemble diagram and spare parts diagram and lay particular emphasis on to carry on spread to move stalk module, principal axis module and become soon organization, box a body, lubricate and seal completely, spread to move stalk and slippery move wheel gear spare parts of design to complete design tasks.
This highlights the structural design requirements,under the basic requirements for ensuring the machine ,According to the principles of machine tool design,Development of institutional and structural net,Streamlining of the machine tool sector,Strive to reduce production costs,No choice of materials resulting in high strength waste.
