摘 要
設(shè)計(jì)的軋鋼機(jī)為250×3型鋼軋鋼機(jī)，軋輥的直徑為250 mm。軋鋼機(jī)主要用來(lái)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(dòng)機(jī)，傳動(dòng)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(dòng)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(dòng)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(dòng)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

250 Design of wire rod mill
Abstract
Rolling mill designed for 250 x 3 payments rolling mill, roller diameter of 250mm. 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
