食品用雙螺桿擠出機(jī)主機(jī)的設(shè)計說明書.doc

I摘要針對設(shè)計任務(wù)要求，進(jìn)行了組合式食品雙螺桿擠出機(jī)的設(shè)計。首先，進(jìn)行了總體方案的設(shè)計與選擇，確定采用積木式螺桿和剖分式機(jī)筒，有利于提高生產(chǎn)效率，降低擠出機(jī)的制造難度；然后，對擠出機(jī)的各組成子系統(tǒng)進(jìn)行了設(shè)計與計算，主要包括傳動系統(tǒng)、加料系統(tǒng)和擠出系統(tǒng)等的設(shè)計。最后，對關(guān)鍵的零部件進(jìn)行了校核計算?？傮w上看，所設(shè)計的食品雙螺桿擠出機(jī)，結(jié)構(gòu)比較簡單，有較好的進(jìn)料特性、正向輸送特性、良好的混合和自潔性能，而且，生產(chǎn)效率也較高。關(guān)鍵詞：組合式；雙螺桿；自潔IIAbstractAccordingtotherequirement,designmodularfoodtwin-screwextruderdesign.First,designandchoosetheoverallscheme,adoptblockscrewandcylinderprofilefraction,improvetheproductionefficiency,reducethedifficultyoftheextrudermanufacture；thendesignandcalculatetheextrudersubsystems；mainlyincludesthetransmissionsystem,chargingsystemandextrusionsystem,etc.Finally,checkthekeyparts.Overall,thedesignoffoodtwin-screwextruder,thestructureissimple,havegoodfeedingcharacteristics,transportation,goodmixingandself-cleaningperformance,and,theproductionefficiencyishigher.Keywords:modular；twin-screw；self-cleaningI目錄摘要.IAbstract.II第1章緒論.11.1課題研究的意義.11.2雙螺桿擠出機(jī)的發(fā)展概況.11.3雙螺桿擠出機(jī)的組成.31.4雙螺桿擠出機(jī)的主要技術(shù)參數(shù).3第2章總體方案確定.52.1設(shè)計參數(shù).52.2整體方案的擬定.5第3章傳動系統(tǒng)的設(shè)計.73.1電動機(jī)的選擇.73.1.1選擇電動機(jī)類型和結(jié)構(gòu)形式.73.1.2選擇電動機(jī)的容量及轉(zhuǎn)速.73.2初步方案.83.2.1轉(zhuǎn)速圖布置.83.2.2傳動系統(tǒng)和扭矩分配裝置.103.3計算傳動系統(tǒng)裝置的運動和動力參數(shù).113.3.1各軸輸入功率.113.3.2各軸輸入轉(zhuǎn)矩.123.3.3齒輪的齒數(shù).123.3.4第五對齒輪的設(shè)計.123.3.5第二對齒輪的設(shè)計.183.3.6帶輪的設(shè)計.233.3.7軸的初步設(shè)計.273.3.8軸的校核.28第4章擠出系統(tǒng)的設(shè)計.324.1螺桿的設(shè)計.324.1.1螺桿設(shè)計主要指標(biāo).32II4.1.2螺桿主要參數(shù)的設(shè)計.334.2螺桿軸承裝置.364.2.1螺桿軸向力的確定.374.2.2螺桿的強(qiáng)度計算.374.2.3軸承組的工作特點.394.2.4套筒式串聯(lián)推力軸承組.394.2.5軸承設(shè)計原則.404.3機(jī)筒設(shè)計.404.3.1機(jī)筒元件的結(jié)構(gòu)形式.414.3.2機(jī)筒的材質(zhì).44第5章加熱與冷卻裝置.455.1加熱裝置.455.1.1載體加熱器.455.1.2電阻加熱.465.1.3電感應(yīng)加熱器.465.2冷卻裝置.47結(jié)論.48致謝.49參考文獻(xiàn).50IIICONTENTSAbstract.錯誤!未定義書簽。Chapter1Introduction.11.1Thesignificanceoftheresearch.錯誤!未定義書簽。1.2Thedevelopmentoftwin-screwextruderOverview.錯誤!未定義書簽。1.3Compositionoftwin-screwextruder.31.4Themaintechnicalparametersofthetwin-screwextruder錯誤!未定義書簽。Chapter2Overallprogramtodetermine.52.1Designparameters.52.2Theformulationoftheoverallprogram.5Chapter3Transmission.73.1Motorselecting.73.1.1Selectmotortypeofnuclearstructure.73.1.2Selectmotorcapacityandspeed.73.2Preliminaryprogram.83.2.1SpeedChartLayout.83.2.2Torquetransmissionanddistributionequipment.103.3Calculatethemovementandpowertransmissionequipmentparameters錯誤!未定義書簽。3.3.1Theshaftinputpower.錯誤!未定義書簽。3.3.2Theshaftinputtorque.錯誤!未定義書簽。3.3.3Gearteeth.錯誤!未定義書簽。3.3.4Fifthgeardesign.錯誤!未定義書簽。3.3.5Thedesignoftheseco
