壓下機(jī)構(gòu)設(shè)計(jì)
摘要：
說(shuō)明書(shū)當(dāng)中，主要包含了我的設(shè)計(jì)思路和設(shè)計(jì)過(guò)程，以及部分計(jì)算。分為引言、軋機(jī)簡(jiǎn)介（軋延原理、軋機(jī)的分類(lèi)、軋機(jī)的組成、軋機(jī)的結(jié)構(gòu)形式、現(xiàn)狀和發(fā)展趨勢(shì)）、傳動(dòng)方案擬定、電機(jī)的選擇、主傳動(dòng)系統(tǒng)參數(shù)計(jì)算（主減速箱的設(shè)計(jì)、軋輥功率的確定）、壓下系統(tǒng)參數(shù)計(jì)算（副減速箱的設(shè)計(jì)、蝸桿傳動(dòng)參數(shù)計(jì)算、壓下絲杠參數(shù)計(jì)算和強(qiáng)度校核）、潤(rùn)滑（潤(rùn)滑方法、潤(rùn)滑的分類(lèi)和確定潤(rùn)滑方法）設(shè)計(jì)小結(jié)、參考文獻(xiàn)和致謝這幾個(gè)部分。
引言部分主要對(duì)機(jī)械領(lǐng)域內(nèi)的“壓下”進(jìn)行了介紹；軋機(jī)簡(jiǎn)介部分主要對(duì)壓下類(lèi)機(jī)械中的軋延機(jī)械進(jìn)行了介紹；傳動(dòng)方案擬定部分就是對(duì)畢業(yè)設(shè)計(jì)任務(wù)的具體化；電機(jī)的選擇部分就是確定兩個(gè)主、副電機(jī)；主傳動(dòng)系統(tǒng)參數(shù)計(jì)算部分就是對(duì)從主電機(jī)到軋輥這條傳動(dòng)鏈上的轉(zhuǎn)速、功率和傳動(dòng)比進(jìn)行計(jì)算；壓下系統(tǒng)參數(shù)計(jì)算部分就是對(duì)從副電機(jī)到軋輥這條傳動(dòng)鏈上的轉(zhuǎn)速、功率和傳動(dòng)比進(jìn)行計(jì)算；潤(rùn)滑部分就是對(duì)軋延裝置所需的潤(rùn)滑方法和類(lèi)型進(jìn)行確定；設(shè)計(jì)小結(jié)部分就是談?wù)勗谡麄€(gè)設(shè)計(jì)過(guò)程中的心得體會(huì)和收獲。

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.
