2、文獻綜述21/22---------------------------------------------------------------范文最新推薦------------------------------------------------------摘要隨著軋制精度要求的不斷提高和軋制技術(shù)的不斷發(fā)展,軋機發(fā)展得到了長足的進步。而作為研究重要基地,高校實驗室軋機體形龐大,軋輥尺寸大;電機轉(zhuǎn)速快,操作過程危險;設(shè)備過于陳舊,不利于學(xué)生上課掌握設(shè)備的特點。因此設(shè)計了短應(yīng)力微型變速軋機,既可以教學(xué)講解也可以實際軋制薄板。設(shè)計簡化原有實驗室軋機,以
3、1000kg為最大承載能力、軋輥轉(zhuǎn)速0~50mm、輥身直徑40mm、上下輥距離4mm可調(diào)以及能有效軋制1mm為設(shè)計基礎(chǔ),軋機配有兩臺160W可逆電機和調(diào)速箱,采用聯(lián)軸器,可實現(xiàn)異步軋制,四個拉桿下端固定在底板上,頂部與輥縫調(diào)整裝置聯(lián)接,拉桿的中間部分梯形螺紋與放置在機架間的上軋輥軸承座內(nèi)的螺母相嚙合,轉(zhuǎn)動拉桿從而改變輥間間隙,其能夠軋制3mm左右的薄板。11142關(guān)鍵詞:軋機設(shè)計;微型;可逆;短應(yīng)力軋機;異步軋制AbstractWiththecontinuousincreasingrequirementofthemillingprecisionandt
