壓下機構設計
摘要：
說明書當中，主要包含了我的設計思路和設計過程，以及部分計算。分為引言、軋機簡介（軋延原理、軋機的分類、軋機的組成、軋機的結構形式、現(xiàn)狀和發(fā)展趨勢）、傳動方案擬定、電機的選擇、主傳動系統(tǒng)參數(shù)計算（主減速箱的設計、軋輥功率的確定）、壓下系統(tǒng)參數(shù)計算（副減速箱的設計、蝸桿傳動參數(shù)計算、壓下絲杠參數(shù)計算和強度校核）、潤滑（潤滑方法、潤滑的分類和確定潤滑方法）設計小結、參考文獻和致謝這幾個部分。
引言部分主要對機械領域內(nèi)的“壓下”進行了介紹；軋機簡介部分主要對壓下類機械中的軋延機械進行了介紹；傳動方案擬定部分就是對畢業(yè)設計任務的具體化；電機的選擇部分就是確定兩個主、副電機；主傳動系統(tǒng)參數(shù)計算部分就是對從主電機到軋輥這條傳動鏈上的轉速、功率和傳動比進行計算；壓下系統(tǒng)參數(shù)計算部分就是對從副電機到軋輥這條傳動鏈上的轉速、功率和傳動比進行計算；潤滑部分就是對軋延裝置所需的潤滑方法和類型進行確定；設計小結部分就是談談在整個設計過程中的心得體會和收獲。
關鍵詞：壓下機構，軋延機械，軋輥，絲杠，減速箱
Pressing Mechanism Design
Abstract:
In the instruction, mainly includes my design ideas and design process, and some computation. Including the introduction, mill(rolling extension principle, the classification of mill,the component of mill, the structure form, status and development trend), transmission scheme, motor selection, the parameters calculating of main transmission system( main reducer design, determining of rolling power), parameters calculating of pressing system(vice reducer design, parameters calculating of worm drive, parameters calculating of press ball screw and intensity),lubrication(lubrication method,the classification of lubrication),Design summary, references,thanks.
Introduction of mechanical part of main areas of “pressing” are introduced；The main profile of rolling over the next class machinery are introduced in the deferred mechanical；Transmission scheme worked for graduation design is the embodiment of the task；The part of motorselection is sure to two motors；Main transmission system parameters are calculated from；The main motor is part of the transmission chain to roll on speed, power and transmission；Pressing system parameters calculation is from vice motor to roll the transmission chain of speed, power and transmission；Lubrication part is needed for rolling extension device type lubrication and determine；Design summary is about in the summary parts in the process of design experiences and harvest.
