That tradition dress going over puts up stove method all is to adopt manual operation , the inner takes out again from the stove after sending workpiece in furnace chamber heat treatment. The electric furnace furnace chamber is deep since the box is dyadic , workpiece can only pass in and out of a furnace gate in level direction and , minor workpiece is flung handily moving forward, big workpiece raise till the crossing uses crowbar to wait to push entering a furnace gate, labor intensity is very big. For this purpose, we have brought forward design about that problem in graduation practice prelude , the turnover that machine uses when heat treatment heats in the machinery parts massproducing has expected that , the turnover applying to electric furnaces of furnace chamber more dyadic than deep box such as RJX759 and RJX959 type specially when heating durable household appliances has expected that, also may be used for close to abovementioned dyadic box electric furnace furnace chamber dimension fuel stove. In the day after tomorrow the type box is also Yong Yu other dyadic as a result of being seriated stove. Dyadic box electric furnace turnover expects that the machine plete machine external form seals off the type handcart for one, driving force system , pushandpull drive system , pushandpull organization , chassis , electromagnetism controlling system , going on foot from electrical equipment stop returning system waiting for part made up of, besides be qualified for have parts and auxiliary equipment floor slide way , stove inner slide way and fuel dress of electrical equipment function units among them experiences and observes an inner in the handcart , has the under the control of button box to control that in extracorporeal distant work distance using only.Keywords: Dyadic electric furnace of box。 Pushandpull organizationVI目 錄摘 要 IIIABSTRACT IV目錄.................................................................................................................................................V1 緒論 12 設(shè)計(jì)方案的確定 3 主要結(jié)構(gòu)【1】 3 工作過程 3 主要性能指標(biāo) 33 傳動(dòng)機(jī)構(gòu)的設(shè)計(jì)與計(jì)算 5 錐齒輪的設(shè)計(jì)[1] [2] [3] [4] [5] [7] [9] 5 錐齒輪軸的設(shè)計(jì) 8 軸上零件的固定[1] [2] [3] [8] [12] 8 花鍵的設(shè)計(jì)[1] [2] [3] [12] 9 軸承的選擇[1] [2] [3] [4] [8] [10] [12] 9 軸的強(qiáng)度計(jì)算 [2] [3] 11 軸的剛度計(jì)算[2] [3] 13 傳動(dòng)軸的設(shè)計(jì) 13 軸上零件的固定[11] [14] 13 花鍵的校核[4] 13 軸承的校核[4] 13 軸的強(qiáng)度計(jì)算[2] [3] 15 軸的剛度計(jì)算[2] [3] 17 減速箱箱體的設(shè)計(jì)[12] [15] [16] 184 行走機(jī)構(gòu)設(shè)計(jì)與計(jì)算 19 對(duì)機(jī)構(gòu)進(jìn)行受力分析[2] [3] 19 輪軸和滾輪扭矩的計(jì)算[2] [3] 19 后輪軸的尺寸計(jì)算[2] [3] 19 后輪軸的強(qiáng)度計(jì)算[2] [3] 21 后輪軸座的選擇及軸承壽命的校核[4] 24 前輪軸的尺寸計(jì)算[2] [3] 25 前輪軸的強(qiáng)度計(jì)算[2] [3] 26 前輪軸的選擇及軸承壽命的校核【4】 30 減速機(jī)的輸出扭矩和輸出功率的計(jì)算[2] [3] [4] 315 推拉機(jī)構(gòu)的設(shè)計(jì)與計(jì)算 32 鏈輪和鏈條的設(shè)計(jì) 32 鏈傳動(dòng)的特點(diǎn)[17] [19] 32 鏈傳動(dòng)的尺寸計(jì)算[2] [3] [4] 32 中間長軸的設(shè)計(jì) 34 軸上零件的固定[2] [3] [4] [9] [11] 34 花鍵的校核[4] 34 軸承的選擇[2] [3] [4] 34 軸的強(qiáng)度計(jì)算[2] [3] 35 軸的剛度計(jì)算[2] [3] 376 其他部件的校核 38 連接鋼管的選擇[1] [7] 38 鋼管彎曲強(qiáng)度校核[2] [3] [4] 38 螺栓校核[2] [3] [4] [8] [9] 397 結(jié)論與展望 40 結(jié)論 40致 謝 41參考文獻(xiàn) 42VRX95J型箱式電爐進(jìn)出料機(jī)設(shè)計(jì)1 緒論 畢業(yè)論文是大學(xué)里面的最后一個(gè)環(huán)節(jié)，這是對(duì)我們大學(xué)四年學(xué)習(xí)的一個(gè)總結(jié)。 本次畢業(yè)設(shè)計(jì)的題目是箱式電爐的自動(dòng)進(jìn)出料機(jī)械手，通過工廠的實(shí)地考察發(fā)現(xiàn)現(xiàn)在工廠由于箱式電爐爐膛深，且工件只能在水平方向進(jìn)出爐門，小工件隨手甩進(jìn)，大工件抬至路口用撬棒等推入爐門，勞動(dòng)強(qiáng)度很大。 把小型工件送入箱式爐內(nèi) 把大型工件送入箱式爐內(nèi) 為此，我們在畢業(yè)設(shè)計(jì)前提出了有關(guān)該課題的設(shè)計(jì)，該機(jī)使用于批量生產(chǎn)的機(jī)械零件熱處理加熱時(shí)的進(jìn)出料，特別適用于RJX759和RJX959型等爐膛較深的箱式電爐加熱大件時(shí)的進(jìn)出料，也可用于爐膛尺寸與上述箱式電爐相近的燃料爐。箱式電爐進(jìn)出料機(jī)的整機(jī)外形為一密封型小車，由電器控制系統(tǒng)、行走動(dòng)力系統(tǒng)、推拉傳動(dòng)系統(tǒng)、推拉機(jī)構(gòu)、機(jī)架、電磁止退系統(tǒng)等部分組成，此外還配有配套件地面導(dǎo)軌、爐內(nèi)導(dǎo)軌及燃料等。452 設(shè)計(jì)方案的確定 主要結(jié)構(gòu)【1】。此外還配有配套的地面鐵軌、爐內(nèi)導(dǎo)軌及燃料等。 箱式電爐進(jìn)出料機(jī)械手的主要結(jié)構(gòu) 工作過程將進(jìn)出料機(jī)械手平穩(wěn)地放在用混凝土澆筑的地面鐵軌上，爐內(nèi)導(dǎo)軌安放在爐底板上，通過行走傳動(dòng)系統(tǒng)傳動(dòng)，進(jìn)出料機(jī)械手在鐵軌上作前進(jìn)和后退運(yùn)動(dòng)，即可驅(qū)使遠(yuǎn)離爐門；裝料時(shí)，駛近爐門使機(jī)上導(dǎo)軌與爐內(nèi)導(dǎo)軌接攏，同時(shí)，電磁止退系統(tǒng)動(dòng)作，止退鉤鉤住爐體，防止向爐膛推送料板時(shí)機(jī)體的后移；通過推拉傳動(dòng)系統(tǒng)傳動(dòng)，推料頭可預(yù)先裝好工件的料板推進(jìn)爐膛；出料時(shí)，則由拉料鉤從爐膛拉出料板及已加工完成的工件，到位后拉料鉤自動(dòng)彈出，用其中設(shè)備掉走料板和工件，經(jīng)兩次推拉聊過程即可完成一個(gè)裝料周期。3 傳動(dòng)機(jī)構(gòu)的設(shè)計(jì)與計(jì)算 錐齒輪的設(shè)計(jì)[1] [2] [3] [4] [5] [7] [9] 根據(jù)出料機(jī)傳動(dòng)的工作要求，采用漸開線直齒圓錐齒輪機(jī)構(gòu)以實(shí)現(xiàn)兩相交軸之間的傳動(dòng)。兩齒輪均選用45鋼，硬度為217255HB。mm==Z1=19, Z2=34選8級(jí)精度KA=KV==KHa==K=T0=259972N錐齒輪有軸向力，擬采用一對(duì)30208單列圓錐滾子軸承，兩個(gè)軸承之間用套筒定位，套筒內(nèi)經(jīng)取60mm,外徑取80mm，左端軸承用透蓋外徑定位，內(nèi)徑用套筒定位，套筒選用903622，右端軸承采用套筒內(nèi)徑定位，采用軸肩擋圈外徑定位。,k=(載荷不均勻系數(shù))，h=(Dd)/22c=, =(D+d)/2=,T=103045=所以花鍵強(qiáng)度符合要求。表33 軸承的選擇與校驗(yàn)計(jì)算項(xiàng)目計(jì)算內(nèi)容計(jì)算結(jié)果附加軸向力軸承軸向力 軸承2被壓縮，故= = 續(xù)表33計(jì)算項(xiàng)目計(jì)算內(nèi)容計(jì)算結(jié)果X、Y的值沖擊載荷系數(shù)當(dāng)量動(dòng)載荷軸承壽命計(jì)算額定靜載許用轉(zhuǎn)速計(jì)算載荷系數(shù)f1載荷系數(shù)f2許用轉(zhuǎn)速N e= X1=1,Y1=0 X2=1,Y2=0考慮中等沖擊，查表 因?yàn)镻1〉P2，所以只計(jì)算軸承1的壽命 X0=，Y0= 取最大值50216N P0r1=Pr1 P0r2=X0Fr2+Y0Fα2 取最大值32387N 正常使用單列圓錐滾子軸承查表得S0= =125540N 因?yàn)椋灾挥?jì)算軸承
