435 小型軋鋼機(jī)設(shè)計(jì),小型,軋鋼機(jī),設(shè)計(jì) 摘 要設(shè)計(jì)的軋鋼機(jī)為 300×3 型鋼軋鋼機(jī)，軋輥的直徑為 300 mm。軋鋼機(jī)主要用來為軋制小型線材，采用三輥式工作機(jī)座。軋鋼機(jī)的主要設(shè)備是由一個(gè)主機(jī)列組成的。軋鋼機(jī)的主機(jī)列是由原動機(jī)，傳動裝置和執(zhí)行機(jī)構(gòu)三個(gè)基本部分組成的。采用的配置方式為電動機(jī)——減速機(jī)——齒輪機(jī)座——軋機(jī)。由于軋輥的轉(zhuǎn)向和轉(zhuǎn)速不可逆轉(zhuǎn)，原動機(jī)采用造價(jià)較底的高速交流主電機(jī)?？紤]到軋制負(fù)荷很不均勻，為了均衡電機(jī)負(fù)荷，減少電機(jī)的容量，在減速機(jī)和電動機(jī)之間加有飛輪。齒輪機(jī)座：其用途是傳遞轉(zhuǎn)矩給工作輥，設(shè)計(jì)采用三個(gè)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(jī)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(jī)　　齒輪機(jī)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(jī)的定義……………………………………………………11.2 軋鋼機(jī)的標(biāo)稱……………………………………………………11.3 軋鋼機(jī)的用途……………………………………………………11.4 軋鋼機(jī)的主機(jī)列…………………………………………………2第 2 章 軋制壓力和軋制力矩的計(jì)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(jī)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(qiáng)度的校核 ………………………………………………13第 4 章減速器的選則 ………………………………………………………144.1 傳動比的計(jì)………………………………………………………144.2 減速器的特點(diǎn)和破壞形式………………………………………164.3 主減速機(jī)的結(jié)構(gòu)…………………………………………………164.4 主減速器的潤滑和防護(hù)…………………………………………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(jī)座的設(shè)計(jì)……………………………………………………195.1 齒輪機(jī)座的類型和結(jié)構(gòu)…………………………………………195.2 齒輪的設(shè)計(jì)和軸端強(qiáng)度的校核…………………………………195.3 密封和漏油的問題………………………………………………225.4 齒輪機(jī)座的潤滑…………………………………………………225.5 齒輪機(jī)座的總述…………………………………………………22第 6 章軋鋼機(jī)工作機(jī)座設(shè)計(jì) ………………………………………………246.1 工作機(jī)座的選擇…………………………………………………2426.2 軋輥與軋輥軸承的設(shè)計(jì)…………………………………………256.3 軋輥調(diào)整裝置的設(shè)計(jì)……………………………………………286.4 機(jī)架結(jié)構(gòu)的設(shè)計(jì)…………………………………………………306.5 機(jī)架強(qiáng)度的校核…………………………………………………31第 7 章孔型的設(shè)計(jì) …………………………………………………………35第 8 章經(jīng)濟(jì)分析 ……………………………………………………………38第 9 章專題設(shè)計(jì) ……………………………………………………………39總 結(jié)…………………………………………………………………………46致 謝…………………………………………………………………………47參考文獻(xiàn) ……………………………………………………………………48附錄 1 外文譯文 ……………………………………………………………49附錄 2 外文譯文 ……………………………………………………………57
