數(shù)控車床主傳動機(jī)構(gòu)設(shè)計(畢業(yè)設(shè)計論文)

1、鹽城工學(xué)院機(jī)械工程系畢業(yè)設(shè)計1摘要本文作者研究的主要是數(shù)控車床的主傳動系統(tǒng)，這類主傳動系統(tǒng)的設(shè)計可用于對普通車床的改造，以適應(yīng)當(dāng)前我國機(jī)床工業(yè)發(fā)展的現(xiàn)狀，具有一定的經(jīng)濟(jì)效益和社會效益。本文作者完成的設(shè)計主要包括根據(jù)一些原始數(shù)據(jù)（其中包括機(jī)床的類型、規(guī)格等）結(jié)合實際條件和情況對車床一些參數(shù)進(jìn)行擬定，再根據(jù)擬定的參數(shù)，進(jìn)行傳動方案的比較，確定傳動方案。然后計算各傳動副的傳動比及齒輪齒數(shù)，再估算齒輪的模數(shù)和各軸的軸徑，并對齒輪和軸的強(qiáng)度、剛度

2、進(jìn)行校核。除此之外，還要對箱體內(nèi)的主要結(jié)構(gòu)進(jìn)行設(shè)計，一些零件的選型，如電磁離合器的選擇等，從而完成對整個主傳動系統(tǒng)的設(shè)計。關(guān)鍵詞關(guān)鍵詞：數(shù)控車床主傳動系統(tǒng)設(shè)計AbstractAbstractWhatauthofthistextstudynumericalcontrolmaintransmissionoflathemainlythemaindesignoftransmissioncanuseftodinarytransfmationofl
