1、畢業(yè)設(shè)計(jì)(論文)題目:液壓挖掘機(jī)反鏟工作裝置設(shè)計(jì)學(xué)院:航空制造工程學(xué)院專業(yè)名稱:機(jī)械設(shè)計(jì)制造及其自動(dòng)化班級(jí)學(xué)號(hào):08031717學(xué)生姓名:指導(dǎo)教師:二O一二年六月液壓挖掘機(jī)反鏟裝置設(shè)計(jì)摘要:液壓挖掘機(jī)是一種重要的工程機(jī)械,它的廣泛應(yīng)用對(duì)于減輕勞動(dòng)量,保證工程質(zhì)量,加快工程進(jìn)度,提高勞動(dòng)生產(chǎn)率起了巨大的作用。反鏟工作裝置由動(dòng)臂,斗桿,動(dòng)臂液壓缸,斗桿液壓缸和鏟斗液壓缸組成。本文根據(jù)液壓挖掘機(jī)反鏟裝置的結(jié)構(gòu)特點(diǎn)和工作原理,對(duì)其各主要機(jī)構(gòu)進(jìn)行了運(yùn)動(dòng)學(xué)分析。并在此基礎(chǔ)上,根據(jù)設(shè)計(jì)說(shuō)明書(shū)的設(shè)計(jì)要求,結(jié)合各機(jī)構(gòu)的工作
2、特點(diǎn)和設(shè)計(jì)要求,在對(duì)各機(jī)構(gòu)分析計(jì)算的同時(shí),結(jié)合構(gòu)件已知尺寸參數(shù),算出各機(jī)構(gòu)中構(gòu)件的其它參數(shù),為各構(gòu)件的結(jié)構(gòu)設(shè)計(jì)提供數(shù)據(jù)支撐。挖掘力是衡量挖掘機(jī)挖掘能力的重要參數(shù)。挖掘力是由各液壓缸中的油液壓力提供的,是主動(dòng)力。最大挖掘力的實(shí)現(xiàn)受諸多因素的制約,它是工作裝置各鉸點(diǎn)受力分析的基礎(chǔ)。挖掘阻力不僅與鏟斗的尺寸形狀有關(guān),還與挖掘?qū)ο笥嘘P(guān),是兩者的綜合反映。關(guān)鍵詞:液壓挖掘機(jī)反鏟裝置運(yùn)動(dòng)分析參數(shù)設(shè)計(jì)力學(xué)分析指導(dǎo)老師簽名:TheDesignforBackhoeEquipmentoftheHydraulicExcavat
