1、摘要擠出機(jī)，主機(jī)是擠塑機(jī)，它由擠壓系統(tǒng)、傳動(dòng)系統(tǒng)和加熱冷卻系統(tǒng)組成。擠出機(jī)是一種常見(jiàn)的塑料機(jī)械設(shè)備，近年來(lái)，中國(guó)常規(guī)擠出機(jī)及生產(chǎn)線，以?xún)?yōu)異的性?xún)r(jià)比逐漸走俏國(guó)際巿場(chǎng)。同時(shí)，中國(guó)在先進(jìn)擠出技術(shù)領(lǐng)域不斷創(chuàng)新，開(kāi)拓出了多種新型擠出產(chǎn)品。精密擠出技術(shù)適應(yīng)高精加工需要精密擠出成型可以免去后續(xù)加工手段，更好地滿(mǎn)足制品應(yīng)用的需求，同時(shí)達(dá)到降低材料成本、提高制品質(zhì)量的目的。如今，滿(mǎn)足塑料制品精密直接擠出的需要，多種成熟的技術(shù)已經(jīng)推向巿場(chǎng)，聚合物熔體齒輪泵就是其中一種重要手段。這一技術(shù)已經(jīng)廣泛應(yīng)用于化纖、薄膜、型材、管材、板材、線纜、復(fù)合擠出、造粒等生產(chǎn)線。單螺桿塑料擠出機(jī)采用單個(gè)減速機(jī)、單個(gè)螺筒、螺桿采用正
2、規(guī)型材、優(yōu)質(zhì)碳素鋼。特殊要求采用高強(qiáng)度耐腐蝕的合金鋼經(jīng)多級(jí)熱處理和精加工而成，脫水排氣，可配導(dǎo)熱油節(jié)能裝置，能耗比低。此次設(shè)計(jì)說(shuō)明書(shū)根據(jù)具體參數(shù)的計(jì)算和工況的分析，從而制定了總體的控制方案。經(jīng)過(guò)各種方案對(duì)比后，設(shè)計(jì)出擠出機(jī)低速軸齒輪的設(shè)計(jì)。關(guān)鍵詞：擠出機(jī)；低速軸齒輪；機(jī)筒；機(jī)頭AbstractExtruder,thehostiscrowdedmoldingmachine,itiscomposedofextrusionsystem,transmissionsystemandheatingcoolingsystem.Extruderisakindofcommonplasticmachinery
