帶輪設帶輪設計要求和帶輪材料設計帶輪時，應該是其重量輕，質量分布均勻。當圓周速度v＞5米/秒時，要進行靜平衡；當v＞25米/秒時，需進行v≤25米/秒時用HT15-33V=25-30米/秒時用HT20-帶速V30msHT200制造，高速時應45m/sv22.92m/sHT200。在設計帶輪結構時，應使帶輪易于制造，能避免因Za可根據(jù)帶輪8。D140mm，取Za4V帶型號：B 頂部寬b：17㎜節(jié)寬bp：14.0㎜高度h：11mm楔：V基準寬度bd14.0mm 基準線上槽深hamin4mm 基準線下槽hfmin12mm槽間距e190.4mm 槽邊距fmin12mm 最小輪緣厚min8mmBZ1)e2f（Z—輪槽數(shù)，外徑dadd3.24帶傳動的張緊裝置.采用張緊輪圖適用于中心距不能調(diào)節(jié)的帶傳動中，利用張緊輪將帶3-33-3帶傳動安裝、使用和過早磨損，使帶，軸承工作。1.5%軸的結構3-7軸的強度軸除受彎矩外，還受變形。所以用彎扭組合變形對軸進行強度校核。米的理論重量，由GS可以計算其中 G——給定厚度的鋼板每平方米的理論重量kg/S——鋼板厚度

主軸上的刀具設主軸上刀具采用內(nèi)齒刀、外齒刀、750%左右。刀具結構各部位是根據(jù)力的要求和安裝葉片的功超過切削阻力的功時將多余的能量貯使動能增大時速率增3-3-176把鋸齒形刀具和一個螺旋型刀組成，主要是將大塊的1)657型刀組成。刀具的材料選用高速鋼材料，刀[28]3-18：3-18磨削組件的組要是將從絞龍中加工出來的物料進行精加工。主軸帶動57碰撞等不同的方式充分的將物料打碎磨削組件上還裝有6塊刮刀，將加工好的并且粘在箱體壁上的細物料掛下來。能夠保證所加工出來的物料全部得到利用。3-3-19主切削軸組件結構示意圖軸承材料的選硬度一般不低于HRC60。一般這些元件需要150度回火處理，所以其通常120度，此時，硬度不會下降。軸承類型的選因為該型號的機，其主軸的轉速在3800rm左右。所以主軸上（300系列[5]。為了便于軸承在主軸上的安裝和拆卸選用帶立式座的UCP系列軸承，4-1。圖4- UCP系列軸承簡解該系列軸承的優(yōu)點、缺點、以及使用情況。本設計運用UCP系列軸承滿第五 安全操作1、機固定作業(yè)，應固定在水泥基礎上。如果經(jīng)常變換工作地點機與電動機要安裝在用角鐵制作的機座上如果機用柴油機作動力，應使兩者功率匹配，即柴油機功率略大于機功率，并使兩者的皮帶輪槽一致。皮帶輪外端面要在同一平面上。2、開機前必須檢查機組的各部分連接螺栓是否緊固，傳動皮帶的松緊度是否合適，電源線是否良好。電動機軸和機軸是否平行。先3、檢查錘片是否良好，篩片的孔徑是否合適，有無損壞。用手拖動皮帶，檢查主軸轉動是否靈活，有無卡、碰及摩擦現(xiàn)象。4、開機后，先使設備空轉2—3分鐘，檢查轉子轉向是否正確，聲音是否正常。只有在額定轉速下轉動平穩(wěn)后才可工作。5、工作中要隨時注意機的運轉情況，送料要均勻，以防阻塞悶車，不要長時間超負荷工作。若發(fā)現(xiàn)有振動、雜音、軸承與機體溫度過高、向外噴料等現(xiàn)象，應立即停車檢查，排除故障后方可繼續(xù)工作。6、的物料應仔細檢查，不得混有石塊、金屬等異物，以免損壞機器。7、機器運轉時，操作人員不得離開機組，也不得在運轉中拆機觀察室內(nèi)的工作情況，維修工具不得放在機器或填料上。8、操作人員不要戴手套，發(fā)生堵塞時，嚴禁將手伸進填料斗中，送料時應站在機側面，以防反彈雜物打傷面部9、工作結束后不要立即停機，應空轉2—3分鐘，以便讓機內(nèi)物料完全排出。停機后應進行清掃、保養(yǎng)工作。10.不要隨便更換皮帶輪,以防轉速過高使室產(chǎn)生,或轉速太低1、機一般采用電機直接聯(lián)接裝置，這種連接方式簡單、易維修但是如果在裝配過程中兩者不能很好連接就會造成機的整體振動。(1)電機轉子與機轉子不同心?？勺?、右移動電機的位置，或在電機底腳下面加墊，以調(diào)整兩轉子的同心度。(2)機轉子不同心。其原因是支掌轉子軸的2個支承面不在同一個平面內(nèi)?？稍谥С休S承座底面墊銅皮，或在軸承底部增加可調(diào)的楔鐵，經(jīng)保證2個軸頭同心。(3)室部分振動較大。其原因是聯(lián)軸器與轉子的聯(lián)接不同心或轉子內(nèi)部的平錘片質量不均勻。可根據(jù)不同類型聯(lián)軸器采取相應的方法凋整聯(lián)軸器與電機的聯(lián)接：當錘片質量不均時，須重新選配每組錘片，使相對稱的錘片，使相對稱的錘片誤差小于5G。(4)原有的平衡被破壞。電機修理后須做動平衡試驗，以保證整體的匹平衡。(5)機系統(tǒng)的地腳螺栓松動或基礎不牢，在安裝或維修時，要均勻地緊固地腳螺栓，在地腳基礎和機之間，要裝減震裝置，減輕振動。(6)錘片折斷或室內(nèi)有硬雜物。這些都會造成轉子轉動的不衡，而引起整機振動。因此，要定期檢查，對于磨損嚴重的錘片。在更換時要對稱更換機運轉中出現(xiàn)的不正常聲音要馬上停機檢查查找原因及時處理。(7)機系統(tǒng)與其他設備的聯(lián)接不吻合。例如進料管、出料管等聯(lián)接不當，會引起振運和造聲。因此，這些聯(lián)接部，不宜采用硬聯(lián)接，最好采用軟聯(lián)接。2軸承過熱軸承是機上較為重要的配件其性能直接影響到到設備的正常運行及生產(chǎn)效率。設備運行過程中，使用者要特別注意軸承的升溫和軸承部位的噪聲，出現(xiàn)異常要及早處理。2個軸承座高低不平，或電機轉子與機轉子不同心，會使軸承受到額外負荷的沖擊，從而引起軸承過熱。出現(xiàn)這種情況，要馬上停機排除故障，以避免軸承早期損壞。軸承內(nèi)潤滑油過多、過少或老化也是引起軸承過熱而損壞的主要原因，因此，要按著使用使要求按時定量地加注潤滑油，一般潤滑占軸承空間的70%-80%，過多或過少都不利于軸承潤滑和熱傳遞。軸承延長其使用。軸承蓋與軸的配合過緊，軸承與軸的配合過緊或過松都會引軸承過熱。一但發(fā)生這種問題，在設備運轉中，就會發(fā)出磨擦聲響及明顯的擺動。應停機拆下軸承。修整磨擦部位，然后按要求重新裝配。、3機堵塞是機使用中常見的故障之一，可能有機具設計上存在的問題，但是由于使用操作不當造成的。、進料速度過快，負荷增大，造成堵塞。在進料過程中，要隨時注意電流表指針偏轉角度大，如果超過額定電流，表明電機超載，長時間過載，會燒壞電機。出現(xiàn)這種情況應立即減小或關閉料門，也可以改變進料的方式，通過增加喂料器來控制進料量。喂料器有手動、自動兩種，用戶應根據(jù)實際情況選擇合適的喂料器。由于機轉速高、負荷，大，并且負荷的波動性較強。所以機工作時的電流一般控制在額定電流的85%左右。，出料管道不暢或堵塞進料過快，會使機風口堵塞；與輸送設備匹配不當會造成出料管道風減弱或無風后堵死。查出故障后，應先清通送口變更不匹配的輸送設備，調(diào)整進進料量，使設備正常運行。機堵塞應定期更新折斷和嚴重老化的錘片保持機良好的工作狀，態(tài)，并定期檢查篩網(wǎng)的物料含水率應低于14%，這樣既可提高生產(chǎn)效率，又使機不堵塞，增強機工作的可靠性。，總是低硬度物料超細機的結構設計。在老師的細心指導下，我們認真分析設計方案，勤于思考，完成了畢業(yè)設計任務。通過這次畢業(yè)設計使我初步掌握了低硬度物料超細機設計的一般合理的結構方案正確選擇機的各性能參數(shù)根據(jù)工作的設計原則設計過程中，我從學校館搜集了大量資料，并通過網(wǎng)絡搜索查找了有關機工作原理的許多信息。本次設計是我們大學階段所學知識的大綜合。通過設計，上學到的理論知識得到了實踐，做到了理論聯(lián)系實際，致方如果沒有指導老師的督促指導以及同組的支持完成這個畢業(yè)設計是很的。。本雖然凝聚著自己的汗水但卻不是個人智慧的產(chǎn)品沒有導師的打折扣當我打完的最后一個字符涌上心頭的不是長途跋涉后抵達終點的欣喜，而是源自心底的誠摯謝意。我首先要感謝我的導師波老師對我的構思以及的內(nèi)容不厭其煩的進行多次指導和悉心指點鼓勵老師一絲不茍的作風，嚴謹求實的態(tài)度，踏踏實實的精神，不僅授用言語表達的，使我在完成的同時也深受啟發(fā)和教育。。再次由衷感謝答辯組的各位老師對學生的指導和教誨，我也在努力的參考文楊蘭玉,.國內(nèi)外納米細物料的現(xiàn)狀分解的基本研究[J].林業(yè)機械與木工設備,2012.04.楊蘭玉,.發(fā)電用細物料理論及裝備的設計[J].機械設計與制造,2009.06.趙蔚,.旭生物質發(fā)電的效益分析[J].環(huán)境保護與循環(huán)經(jīng)濟,2009.11,開碇,.國內(nèi)外生物質成型及燃燒設備研究與開發(fā)現(xiàn)狀[J]2002.04王慧,,.納米細物料在木材工業(yè)的應用前景展望[J].林業(yè)機械與木工備,2005,(11).鄭鳴皋.破碎機綜述.機械工業(yè),2011劉榮榕,王鵬,,,.微波處理與接枝對PVC/細物料復合材料結構與性能的影響[J].中國塑料,2007,(11).王仲春.水泥工業(yè)粉磨工藝技術.:中國建材工業(yè),2012.粉磨工藝及設備.:理工大學,2002竇履豫.磨粉機的制作精度和設計創(chuàng)新[J],2007,(01)方曉敏.小型磨粉機的有關設計計算[J]1983,(01).材料力學.航空航天大學，2010（02）.欽,李汝莘.超小型磨粉機設計研究[J],199905)武文斌,黃衛(wèi)文,.盤式磨粉機的技術及應用[J].糧食與飼料工業(yè),2004,(01).馬新民.礦山機械(選礦機械部分).中國礦業(yè)大學,2009.8.大型水泥磨結構及傳動設計研究[D].華技大學,2006.10.詹承先.全自動研磨劑的研究和設計[D],2008.11,高志主編.機械設計.:高等教育V1510198710.錘式破碎機配錘圖表的編制和應用.杭州機械工業(yè),1999張展主編機械設計通過手冊.:機械工業(yè):2008朱昆泉,許林發(fā).建材機械工程手冊.:工業(yè)大學,2000濮良貴紀名剛.《機械設計》第九版高等教育XIAOJun.PresentsituationinDomesticandAbroadandDevelotrendofConeCrusher.COPPERENGINEERING,2010(3),87-89.[sikongL,HashimotoH,AshimaS,Breakagebehavioroffineparticlesofbrittlemineralsandcoal.powertechnology,1990.Superfinecrushingtechnologyresearchsituationand:thesuperfinecrushingtechnologyinindustrialmineralsprocessingoccupiestheimportantposition,therelevantapplicationfieldforallkindsofultrafinepowderproductanincreasingdemand,superfinecomminutionneedtoimprove.Forthecurrentstudyofultra-finecomminutiontechnologyysisofthecurrentsituation,pointsoutthefutureofultra-finecomminutiontechnologydevelopmenttrend.:superfinecrushing;Industrialminerals;Mechanism;Equipment;DevelopmenttrendSuperfinecrushingtechnologyiswithhightechnologyandmodernnewmaterialindustry,suchasmicroelectronicsandinformationtechnology,aviationtechnology,hightechnicalceramics,refractorymaterials,polymermatrixcompositesandnewenergy,biologicalchemicalindustrytechnologyprogressandmineralprocessingdevelopedengineeringtechnology,has
