【正文】 cowherd, Niulang, who lived with his elder brother and sisterinlaw. But she disliked and abused him, and the boy was forced to leave home with only an old cow for pany. The cow, however, was a former god who had violated imperial rules and was sent to earth in bovine form. One day the cow led Niulang to a lake where fairies took a bath on earth. Among them was Zhinu, the most beautiful fairy and a skilled seamstress. The two fell in love at first sight and were soon married. They had a son and daughter and their happy life was held up as an example for hundreds of years in China. Yet in the eyes of the Jade Emperor, the Supreme Deity in Taoism, marriage between a mortal and fairy was strictly forbidden. He ordered the heaven troop to catch Zhinu back. Niulang grew desperate when he discovered Zhinu had been taken back to heaven. Driven by Niulang39。 在設(shè)計(jì)過程中,清晰明了的思路是確保設(shè)計(jì)成功的關(guān)鍵,而且必須有整體意識(shí),不能抓著某個(gè)部件或機(jī)構(gòu)進(jìn)行單獨(dú)設(shè)計(jì),否則最后裝配為整機(jī)是就會(huì)出現(xiàn)機(jī)構(gòu)或部件見的沖突等不切實(shí)際的問題。 并加以比較 ? ? 11 ???F SaFa YY ? ? ? 22 ???F SaFa YY ? 得到大齒輪 Z1的數(shù)值大 ⑵、設(shè)計(jì)計(jì)算 mmmmYYzKTmFSaFad 1 3 5 4 5 3 3 2 5321 13??? ????????????? ?? 對(duì)比計(jì)算結(jié)果,由齒面接觸疲勞強(qiáng)度計(jì)算的模數(shù) m 大于由齒根彎曲疲勞強(qiáng)度計(jì)算的模數(shù),由于齒輪的模數(shù) m的大小主要取決于彎曲強(qiáng)度所決定的承載能力,而齒面接觸疲勞強(qiáng)度所決定的承載能力,僅與齒輪的直徑(即模數(shù)與齒輪直徑的乘積)有關(guān),可取有彎曲強(qiáng)度算得的模數(shù) 圓整為標(biāo)準(zhǔn)值 m=5,按接觸強(qiáng)度算得的分度圓的直徑d1=,由此算出小齒輪 Z2的齒數(shù) 自動(dòng)調(diào)相印刷機(jī)傳動(dòng)系統(tǒng)設(shè)計(jì) 30 285 ??? mdz 大齒輪的齒數(shù) Z1 Z1=?28=33 這樣算出的齒輪傳動(dòng),即滿足了齒面接觸疲勞強(qiáng)度,有滿足了齒根彎曲疲勞強(qiáng)度,并且做到結(jié)構(gòu)緊湊,避免浪費(fèi)。 表 45接觸疲勞強(qiáng)度計(jì)算用的齒向載荷分布系數(shù) 錯(cuò)誤 !未找到引用源。 H 計(jì)算接觸疲勞許用應(yīng)力 取失效的概率為 1%,安全系數(shù) S=1,由計(jì)算公式的得到 ② 計(jì)算 A 試算小齒輪 Z2的分度圓直徑 d2t, 代入 ? ?H? 中較小的計(jì)算 ? ? mmZuuKTd Hfdt2532131 ???????????????????????? ? ? 自動(dòng)調(diào)相印刷機(jī)傳動(dòng)系統(tǒng)設(shè)計(jì) 24 1—— 允許一定點(diǎn)蝕的結(jié)構(gòu)鋼;調(diào)質(zhì)鋼;球墨鑄鐵(珠光體、貝氏體);珠光體可緞鑄鐵;滲炭淬火的滲碳鋼 2—— 結(jié)構(gòu)鋼;調(diào)質(zhì) 鋼;滲碳淬火鋼;火焰或感應(yīng)淬火的鋼,;球墨鑄鐵;球墨鑄鐵(珠光體、貝氏體);珠光體可鍛鑄鐵 3—— 灰鑄鐵;球墨鑄鐵(鐵素體);滲氮的滲氮鋼;調(diào)質(zhì)鋼,滲碳鋼 4—— 氮炭供滲的調(diào)質(zhì)鋼,滲碳鋼 圖 43 接觸疲勞壽命系數(shù) 錯(cuò)誤 !未找到引用源。 自動(dòng)調(diào)相印刷機(jī)傳動(dòng)系統(tǒng)設(shè)計(jì) 18 ( 4)確定 V 帶的中心距 a 和基準(zhǔn)長(zhǎng)度 dL 1)根據(jù)式 )(2)( 2121 dddd ddadd ???? 初定中心距 mma 4000 ? 2)由式( 822) [1]計(jì)算帶所需的基準(zhǔn)長(zhǎng)度 mmmmaddddaL ddddd1619]4004)150355()355150(24002[4)()(22202122100???????????????? 由表 82[1]選帶的基準(zhǔn)長(zhǎng)度 mmLd 16000 ? 3)計(jì)算實(shí)際中心距 a mmmmLLaa dd 410)2 160 0161 9400(2 00 ??????? 中心距的變化范圍為 390~420mm ( 5)驗(yàn)算小帶輪上的包角 1? 410 )150355()(180 121 ?????????? add dd? ???? 90151 ( 6)計(jì)算帶的根數(shù) z 1)計(jì)算單根 v 帶的額定功率 rP 由 mmdd 1501 ? 和 min/970rn ? 查表 84a[1]得 kWP ? 根據(jù) min/970rn ? , i= 和 B 型帶 查表 84b[1]得 kWP ?? 查表 85[1]得 ??K ,表 82[1]得 ?LK 于是 蚌埠學(xué)院本科畢業(yè)設(shè)計(jì)(論文) 19 kWKKPPP Lr )()( 00 ?????????? ? 2)計(jì)算 v 帶的根數(shù) z 9 ??? rcaPPz 取 4 根 ( 7)計(jì)算單根 v 帶的初拉力的最小值( 0F ) min 由表 83[1]得 B 型帶的單位長(zhǎng)度質(zhì)量 q=,所以 2m in0 )(500)( qvzvK PKF ca ?????

But the future of packaging equipment is the fastest growing developing countries and regions. Corrugated packaging products is the leader in industry, there are nearly ten thousand cartons (boxes) packaging plant. Over the past decade, the domestic circulation of corrugated cardboard, cardboard boxes (box), enduring demand for printing equipment, in short supply. In addition to daily necessities of life by a large number of cartons, the present, motorcycles, bicycles are also extensive use of carton packaging, in particular, an integral part of daily life from the wicker baskets of fruit are packed in cartons instead. It is predicted that soon, vegetables will also be extensive use of cartons for packaging. With economic progress further development, carton packaging enterprises accelerated renovation will be an urgent need to XX and other corrugated cardboard, cardboard (box) plete sets of equipment. In order to better meet market and customer39。s highprecision multicolor printing carton overlay requirements, sharp price increases for raw materials in recent years, the printing press increased production costs, through the transmission system of this design is optimized for printing by optimizing parameters and selection of new materials and ponents in order to achieve the purpose of reducing the cost of printing press manufacturing Keywords printer。 該機(jī)器所依據(jù)的技術(shù) 原理 :基于自動(dòng)化控制技術(shù)的高速紙板印刷成型機(jī)主要技術(shù)原理如下:瓦楞紙箱生產(chǎn)主要分前后道兩大生產(chǎn)過程:一是瓦楞紙板生產(chǎn),即前道生產(chǎn);二是紙板成型加工,即后道生產(chǎn)設(shè)備。 E、彈振微壓輸紙膠輥系統(tǒng),提高給紙精度。 圖 22 墨路圖 網(wǎng)紋輥、墨輥與送紙部聯(lián)動(dòng)工作,停止送紙時(shí)網(wǎng)紋輥通過電動(dòng)機(jī)(圖 23 中 1)與壓簧(圖 23 中 2)下降與印刷輥 (圖 23 中 3)分離,減少印版(圖 23 中 4)磨損。本機(jī)集光電氣為一體的高 精度時(shí)序控制,效率高、自動(dòng)化程度高,保證了瓦輥紙箱的高品質(zhì)結(jié)合。 主傳動(dòng)系統(tǒng)運(yùn)動(dòng)方式的選擇 主傳動(dòng)系一般由動(dòng)力源、變速裝置及執(zhí)行件,以及開停、換向和制動(dòng)機(jī)構(gòu)等部件組成。 ③ 調(diào)速平滑性好,低速機(jī)械特性較硬,電磁離合器調(diào)速若不加入速度負(fù)反饋形成閉環(huán)系統(tǒng),低速時(shí)不能拖動(dòng)負(fù)載。 印刷機(jī)由于變速運(yùn)行必不可少,采用變頻器可以提高操作性能,可以選用標(biāo)準(zhǔn)電動(dòng)機(jī),容易入手,利于機(jī)器小型化。 ⑴ 選定齒輪的類型、精度等級(jí)、材料和齒數(shù) ① 按圖所示的傳動(dòng)的方案,選用直齒圓柱齒輪傳動(dòng)
