1、雙螺桿壓縮機(jī)的設(shè)計(jì)【摘要】雙螺桿壓縮機(jī)是一種比較新穎的壓縮機(jī)，因其可靠性高、操作維修方便、動(dòng)力平衡性好、適應(yīng)性強(qiáng)等優(yōu)點(diǎn)，而廣泛地應(yīng)用于礦山、化工、動(dòng)力、冶金、建筑、機(jī)械、制冷等工業(yè)部門(mén)。雙螺桿壓縮機(jī)已經(jīng)超過(guò)所有工業(yè)壓縮機(jī)的50％，其市場(chǎng)份額超過(guò)80％，今后其市場(chǎng)份額還將繼續(xù)擴(kuò)大?？梢?jiàn)，研究雙螺桿壓縮機(jī)具有十分重要的意義。本課題主要是設(shè)計(jì)通用的噴油雙螺桿空氣壓縮機(jī)，采用單邊不對(duì)稱(chēng)擺線(xiàn)-銷(xiāo)齒圓弧型型線(xiàn)，陰、陽(yáng)轉(zhuǎn)子齒數(shù)比為6：4。設(shè)計(jì)新型轉(zhuǎn)子型線(xiàn)，目的是使接觸線(xiàn)長(zhǎng)度、泄漏三角形面積和封閉余隙容積3者達(dá)到最優(yōu)化設(shè)計(jì)，以進(jìn)一步提高雙螺桿壓縮
