1、茂名職業(yè)技術(shù)學(xué)院CA6140主軸箱設(shè)計(jì)【摘要】作為主要的車削加工機(jī)床，CA6140機(jī)床廣泛的應(yīng)用于機(jī)械加工行業(yè)中，本設(shè)計(jì)主要針對(duì)CA6140機(jī)床的主軸箱進(jìn)行設(shè)計(jì)，主傳動(dòng)系統(tǒng)是用來實(shí)現(xiàn)機(jī)床主運(yùn)動(dòng)的傳動(dòng)系統(tǒng)，它應(yīng)具有一定的轉(zhuǎn)速（速度）和一定的變速范圍，以便采用不同材料的刀具，加工不同的材料，不同尺寸，不同要求的工件，并能方便的實(shí)現(xiàn)運(yùn)動(dòng)的開停，變速，換向和制動(dòng)等。數(shù)控機(jī)床主傳動(dòng)系統(tǒng)主要包括電動(dòng)機(jī)、傳動(dòng)系統(tǒng)和主軸部件，它與普通機(jī)床的主傳動(dòng)系統(tǒng)相比在結(jié)構(gòu)上比較簡單，這是因?yàn)樽兯俟δ苋炕虼蟛糠钟芍鬏S電動(dòng)機(jī)的無級(jí)調(diào)速來承擔(dān)，剩去了復(fù)雜的齒輪變速機(jī)構(gòu)，有些只有二級(jí)或三級(jí)齒輪變速系統(tǒng)用以擴(kuò)大電動(dòng)
