摘 要
本文介紹了立式數(shù)控銑床的一些基本概況，簡述了機(jī)床主傳動系統(tǒng)方面的原理和類型，分析了各種傳動方案的機(jī)理。立式數(shù)控銑床主傳動系統(tǒng)包括了主軸電動機(jī)、主軸傳動系統(tǒng)和主軸組件三部分組成。本文詳細(xì)介紹了立式數(shù)控銑床主傳動系統(tǒng)的設(shè)計過程，該立式數(shù)控銑床主軸變速箱是靠齒輪進(jìn)行傳動的，主軸箱傳動系統(tǒng)采用齒輪傳動，傳動形式采用集中式傳動，主軸變速系統(tǒng)采用多聯(lián)滑移齒輪變速。齒輪傳動具有傳動效率高，結(jié)構(gòu)緊湊，工作可靠、壽命長，傳動比準(zhǔn)確等優(yōu)點(diǎn)。文中介紹了立式數(shù)控銑床主傳動系統(tǒng)各種傳動方案優(yōu)缺點(diǎn)的比較、主傳動方案的選擇和確定、主傳動變速系統(tǒng)的設(shè)計計算、主軸組件的設(shè)計、軸承的選用基潤滑、關(guān)鍵零件的校核、以及主軸電動機(jī)的控制等設(shè)計過程。

Abstract
this text introduces the sign type number to control some basic general situations of the miller, Chien says the tool machine lord to spread the principle and types of move the systems, analyzing various mechanism that spreads to move the project.The sign type number controls the miller lord to spread to move the system to include the principal axis electric motor, principal axis to spread to move the system and the principal axis module three partses to constitute.Detailed introduction of this text the sign type number controls the design process that the miller lord spreads to move the system, should the sign type number control the miller principal axis to become soon the box is to is carry on by wheel gear to spread to move of, the principal axis box spreads to move the system adoption wheel gear to spread to move, spreading to move the form adoption concentration type to spread to move, the principal axis become soon many of the system adoption slip to move the wheel gear to become soon.The wheel gear spreads to move to have to spread to move the efficiency high, the structure tightly packed, work credibility, the life span is long, spreading to move than accurate etc. advantage.It introduced the sign type number to control the miller lord to spread to move various comparison, lord that spreads to move the project merit and shortcoming of system to spread in the text the choice and assurance, lords of move the projects spread to move to become soon system of design, bearings of design calculation, the principal axis module choose the control of the school pit, and the principal axis electric motor of use the lubrication, the key spare parts etc. the design process.
Key words： the number controls the tool machine;The sign type number controls the miller;The lord spreads to move the system;Principal axis module; Bearings; Principal axis electric motor.
