【文章內(nèi)容簡介】 ?2電機(jī)功率在傳遞過程中必然有一定的損失。參閱機(jī)械工程手冊可知，平帶傳動效率為，減速器齒輪之間傳動效率為 ，減速器傳動效率為 ，其他聯(lián)結(jié)件傳動效率為 。故= ???.所以 此處省略 NNNNNNNNNNNN字 本章小結(jié)本傳送系統(tǒng)設(shè)計部分主要有帶傳動系統(tǒng)、換向裝置組成。傳動系統(tǒng)受力、彎矩、轉(zhuǎn)矩要發(fā)生變形，變形過大就會影響零件的正常工作，影響藥物的傳送。所以要對它們進(jìn)行強(qiáng)度、剛度校核，通過校核，所使用的傳動系統(tǒng)均符合。第四章 其他部件的設(shè)計皮帶用的是平帶，直接安裝在托輥上。 機(jī)架機(jī)架用 Q235 材料鑄造后通過裝配而成，對于強(qiáng)度高的地方要焊接筋板來提高抗壓強(qiáng)度。如圖 41 所示 圖 4—1 機(jī)架 托輥設(shè)計 圖 42圖中 L 是由皮帶寬度決定的，在設(shè)計中把 L 用幾個輪子代替使得托輥與皮帶之間的摩擦減少。如圖 43 所示。下托輥的設(shè)計只是在圖 4—3 里把四個輪子中間的兩個取掉。 圖 4—3 結(jié)論輸送系統(tǒng)的作用是在把藥劑輸送到要求的窗口。在這次設(shè)計中，查閱了關(guān)于運(yùn)輸系統(tǒng)的一些書刊資料，對運(yùn)輸系統(tǒng)包括皮帶機(jī)有了基本的認(rèn)識。在這種情況下，結(jié)合所查閱到的資料，設(shè)計出了三種方案，并對這三種方案進(jìn)行了相互比較，最后選定了第三種方案。方案選定后，隨之對運(yùn)輸系統(tǒng)的傳動系統(tǒng)做了設(shè)計與校核。這些傳動系統(tǒng)有運(yùn)輸帶傳動系統(tǒng)和絲杠傳動系統(tǒng)。在一系列的力、彎矩、轉(zhuǎn)矩計算與校核后，確定所有零件的結(jié)構(gòu)設(shè)計都符合要求。在設(shè)計與校核過程中，電動機(jī)的選擇要綜合考慮試驗機(jī)所輸出力、輸出速度，然后以此倒退求知電機(jī)功率及其外形尺寸。在選擇具體傳動比時，要選擇各種傳動機(jī)構(gòu)合理范圍之內(nèi)的值。畢業(yè)設(shè)計是對四年中所學(xué)知識的一次綜合性的考察，它可以比較全面的檢查我們的專業(yè)知識水平，及時讓我們發(fā)現(xiàn)缺點和不足。在畢業(yè)設(shè)計中，我回顧了四年所學(xué)的知識充分認(rèn)識到了自己的欠缺，學(xué)會了運(yùn)用手冊和查閱相關(guān)書籍資料，更進(jìn)一步的熟練了 CAD 等制圖軟件，學(xué)會了用標(biāo)準(zhǔn)來規(guī)范自己。畢業(yè)設(shè)計和畢業(yè)論文是本科生培養(yǎng)方案的重要環(huán)節(jié)。只有對已學(xué)過的知識真正掌握了，才能吸收新的知識。而新的知識反過來則可以進(jìn)一步促進(jìn)對已學(xué)知識有新的理解。參考文獻(xiàn)[1].吳宗澤、羅圣國，機(jī)械設(shè)計課程設(shè)計手冊（第三版） ， 高等教育出版社，[2].濮良貴、紀(jì)名剛等，機(jī)械設(shè)計（第八版） ， 高等教育出版社，[3].成大先等，機(jī)械設(shè)計手冊， （第四版）化學(xué)工業(yè)出版社，[4].機(jī)械設(shè)計常用標(biāo)準(zhǔn)，機(jī)械原理及零件教研室，機(jī)械工業(yè)出版社，[5].現(xiàn)代機(jī)械傳動手冊 編輯委員會，現(xiàn)代機(jī)械傳動手冊（第二版） ，機(jī)械工業(yè)出版社，[6].汪海濤，冶金機(jī)械設(shè)計手冊， 中國科技文化出版社，[7].楊黎明、黃凱、李恩至、陳實現(xiàn)，機(jī)械零件設(shè)計手冊，國防工業(yè)出版社，225～287[8].孫桓，機(jī)械原理， 高等教育出版社，[9].傅衣銘、熊慧而等，材料力學(xué)， 湖南大學(xué)出版社，[10].廖念釗、莫雨松等，互換性與技術(shù)測量 (第四版)，中國計量出版社，[11].朱孝錄等，機(jī)械傳動設(shè)計手冊，電子工業(yè)出版社，致謝本次設(shè)計是在尊敬的教授的悉心指導(dǎo)和嚴(yán)格要求下完成的，馬老師淵博的知識、嚴(yán)謹(jǐn)?shù)闹螌W(xué)態(tài)度、高度的責(zé)任心以及嚴(yán)于律己、待人誠懇的思想品德深深的影響著我，這不僅使我順利完成了此項設(shè)計，而且也將成為使我受益終生的寶貴財富。幾個月的時間里，從課題的選定、資料的收集、方案的擬定、課題的具體設(shè)計到論文的審定改進(jìn)，馬老師都給與了極大的幫助，傾注了大量的心血。通過這次的畢業(yè)設(shè)計，學(xué)生不僅開拓了思路、擴(kuò)大了視野、豐富了知識面，還初步掌握了處理具體實踐問題的科學(xué)方法，為學(xué)生今后發(fā)展打下了堅實的基礎(chǔ)。從課題的選擇到完成，馬老師都始終給予我耐心細(xì)致的指導(dǎo)和不懈的支持和督促，在此謹(jǐn)向馬老師致以誠摯的謝意和崇高的敬意。附錄 I：英文Numerical control technology and equipping development trend and countermeasureEquip the engineering level, level of determining the whole national economy of the modernized degree and modernized degree of industry, numerical control technology is it develop new developing new hightech industry and most advanced industry to equip (such as information technology and his industry, biotechnology and his industry, aviation, spaceflight, etc. national defense industry) last technology and getting more basic most equipment. Marx has ever said the differences of different economic times, do not lie in what is produced, and lie in how to produce, produce with some means of labor . Manufacturing technology and equipping the most basic means of production that are that the mankind produced the activity, and numerical control technology is nowadays advanced manufacturing technology and equips the most central technology. Nowadays the manufacturing industry all around the world adopts numerical control technology extensively, in order to improve manufacturing capacity and level, improve the adaptive capacity and petitive power to the changeable market of the trends. In addition every industrially developed country in the world also classifies the technology and numerical control equipment of numerical control as the strategic materials of the country, not merely take the great measure to develop one39。s own numerical control technology and industry, and implement blockading and restrictive policy to our country in view of highgrade, precision and advanced key technology of numerical control and equipping. In a word, develop the advanced manufacturing technology taking numerical control technology as the core and already bee every world developed country and accelerate economic development in a more costeffective manner, important way to improve the overall national strength and national position. Numerical control technology is the technology controlled to mechanical movement and working course with digital information, integrated products of electromechanics that the numerical control equipment is the new technology represented by numerical control technology forms to the manufacture industry of the tradition and infiltration of the new developing manufacturing industry, namely the socalled digitization is equipped, its technological range covers a lot of fields: (1)Mechanical manufacturing technology。 (2)Information processing, processing, transmission technology。 (3)Automatic control technology。 (4)Servo drive technology。 (5)Technology of the sensor。 (6)Software engineering ,etc.. Development trend of a numerical control technologyThe application of numerical control technology has not only brought the revolutionary change to manufacturing industry of the tradition, make the manufacturing industry bee the industrialized symbol , and with the constant development of numerical control technology and enlargement of the application, the development of some important trades (IT , automobile , light industry , medical treatment ,etc. ) to the national economy and the people39。s livelihood of his plays a more and more important role, because the digitization that these trades needed to equip has already been the main trend of modern development. Numerical control technology in the world at present and equipping the development trend to see, there is the following several respect [1 ] in its main research focus. 1 A highspeed, high finish machining technology and new trend efficiency, quality are subjavanufacturing technology. Highspeed, high finish machining technology can raise the efficiency greatly , improve the quality and grade of the products, shorten production cycle and improve the market petitive power. Japan carries the technological research association first to classify it as one of the 5 great modern manufacturing technologies for this, learn (CIRP) to confirm it as the centre in the 21st century and study one of the directions in international production engineering. In the field of car industry, produce one second when beat
