3689 小型軋鋼機設(shè)計,小型,軋鋼機,設(shè)計 摘 要設(shè)計的軋鋼機為 300×3 型鋼軋鋼機，軋輥的直徑為 300 mm。軋鋼機主要用來為軋制小型線材，采用三輥式工作機座。軋鋼機的主要設(shè)備是由一個主機列組成的。軋鋼機的主機列是由原動機，傳動裝置和執(zhí)行機構(gòu)三個基本部分組成的。采用的配置方式為電動機——減速機——齒輪機座——軋機。由于軋輥的轉(zhuǎn)向和轉(zhuǎn)速不可逆轉(zhuǎn)，原動機采用造價較底的高速交流主電機?？紤]到軋制負荷很不均勻，為了均衡電機負荷，減少電機的容量，在減速機和電動機之間加有飛輪。齒輪機座：其用途是傳遞轉(zhuǎn)矩給工作輥，設(shè)計采用三個直徑相等的圓柱形人字齒輪在垂直面排成一排，裝在密閉的箱體內(nèi)。聯(lián)軸器：在減速器與齒輪機座之間采用的是安全連軸器。而主聯(lián)軸器采用的的梅花接軸聯(lián)軸器。關(guān)鍵詞：　軋鋼機　　齒輪機座　　飛輪AbstractRolling mill designed for 300 x 3 payments rolling mill, roller diameter of 300 mm. Rolling mill for rolling mainly to small wire rod, a three roller-working machine Block. Rolling mill equipment is a major component of the mainframe out. Rolling mill is the former mainframe is motivated transmission devices and the three basic components of the implementing agencies. Allocation method used for electric motors -- slowdown plane -- plus seat -- rolling mill.The roller to the irreversible and rotational speed, the original motivation for the introduction of a more rapid exchange of the costs of Electrical. Taking into account the rolling load is uneven, to balance electrical loads and reduce the electrical capacity slowdown in the increase between a flywheel and electric motors. Flywheel design and installation of electric motors in decelerator between its role in the adoption roller and roller idling, a mobile storage device in a balanced transmission loads; gear seat : its purpose is to transmit torque to the work revolve, the equivalent diameter cylindrical design used three words plus people lined up in the vertical plane, packed in sealed .Shaft coupling : in the Block reducer and gear is used between security company axle vehicles. Key words：Rolling mill gear seat flywheel.1目 錄摘 要 ……………………………………………………………………I Abstract …………………………………………………………………II第 1 章 緒論…………………………………………………………………11.1 軋鋼機的定義……………………………………………………11.2 軋鋼機的標稱……………………………………………………11.3 軋鋼機的用途……………………………………………………11.4 軋鋼機的主機列…………………………………………………2第 2 章 軋制壓力和軋制力矩的計算………………………………………52.1 軋制平均單位壓力的確定………………………………………52.2 軋制總壓力的確定………………………………………………72.3 軋制力矩的確定 ………………………………………………82.4 電動機的選擇……………………………………………………8第 3 章飛輪的的設(shè) …………………………………………………………103.1 飛輪力矩的確定…………………………………………………10 3.2 飛輪強度的校核 ………………………………………………13第 4 章減速器的選則 ………………………………………………………144.1 傳動比的計………………………………………………………144.2 減速器的特點和破壞形式………………………………………164.3 主減速機的結(jié)構(gòu)…………………………………………………164.4 主減速器的潤滑和防護…………………………………………174.5 齒輪的材料和熱處理……………………………………………174.6 減速器工作狀態(tài)的分析…………………………………………17第 5 章 齒輪機座的設(shè)計……………………………………………………195.1 齒輪機座的類型和結(jié)構(gòu)…………………………………………195.2 齒輪的設(shè)計和軸端強度的校核…………………………………195.3 密封和漏油的問題………………………………………………225.4 齒輪機座的潤滑…………………………………………………225.5 齒輪機座的總述…………………………………………………22第 6 章軋鋼機工作機座設(shè)計 ………………………………………………246.1 工作機座的選擇…………………………………………………2426.2 軋輥與軋輥軸承的設(shè)計…………………………………………256.3 軋輥調(diào)整裝置的設(shè)計……………………………………………286.4 機架結(jié)構(gòu)的設(shè)計…………………………………………………306.5 機架強度的校核…………………………………………………31第 7 章孔型的設(shè)計 …………………………………………………………35第 8 章經(jīng)濟分析 ……………………………………………………………38第 9 章專題設(shè)計 ……………………………………………………………39總 結(jié)…………………………………………………………………………46致 謝…………………………………………………………………………47參考文獻 ……………………………………………………………………48附錄 1 外文譯文 ……………………………………………………………49附錄 2 外文譯文 ……………………………………………………………57
