摘 要 自從 1946 年世界上首次電子計(jì)算機(jī)制造以來 這說明人們制造了工具 能增 加和替換腦力 它和工具 人類在農(nóng)業(yè)和工業(yè)社會(huì) 有了質(zhì)的飛躍 為人類進(jìn)入奠 定了基礎(chǔ)信息社會(huì) 在 1952 年 計(jì)算機(jī)技術(shù)應(yīng)用于機(jī)器 第一個(gè)數(shù)控機(jī)床的誕生 在美國 從那時(shí)起 近年來傳統(tǒng)的機(jī)床 數(shù)控機(jī)床公司逐年增加 并被應(yīng)用在大中 型企業(yè)中 有了質(zhì)量的變化 近半個(gè)世紀(jì)以來 數(shù)控系統(tǒng)經(jīng)歷了兩個(gè)階段和六代 的發(fā)展 在中小企業(yè)甚至個(gè)人企業(yè)也普遍開始使用 在這些數(shù)控機(jī)床 除了少量 的機(jī)床在 FMS 模式集成 主要是在獨(dú)立的運(yùn)行狀態(tài) 和相當(dāng)部分的使用效率不高 落后的管理模式 近年來 中國的出口增長(zhǎng)的大型數(shù)控機(jī)床是數(shù)控車床 數(shù)控磨 床 數(shù)控加工專用機(jī)床 數(shù)控剪板機(jī) 數(shù)控折彎 折彎機(jī) 數(shù)控壓鑄機(jī) 通用機(jī)床 在車床主傳動(dòng)系統(tǒng)的畢業(yè)設(shè)計(jì)中 使學(xué)生建立不錯(cuò)的的規(guī)劃和了解車床主傳 動(dòng)系統(tǒng)設(shè)計(jì)的一般方法 鞏固和加深所學(xué)理論知識(shí) 加深知識(shí)儲(chǔ)備 運(yùn)用所學(xué)知識(shí)剖析和處理設(shè)計(jì) 工作中的實(shí)際問題 從機(jī)械制造裝備畢業(yè)設(shè)計(jì)中 使我們?cè)谥贫ㄜ嚧仓鱾鲃?dòng)機(jī)構(gòu) 車床的結(jié)構(gòu) 設(shè)計(jì) 一般的提案的設(shè)計(jì) 零件等的計(jì)算 編繪技術(shù)文稿和設(shè)計(jì)理論的表現(xiàn)等 方面 得到整體性的鍛煉 輕車熟路相關(guān)準(zhǔn)則 圖冊(cè)和參照素材的使用 以懂得具有粗淺的結(jié)構(gòu)剖析 和構(gòu)造的設(shè)計(jì)演算的能力 關(guān)鍵詞 主傳動(dòng)系統(tǒng) 傳動(dòng)設(shè)計(jì) 動(dòng)力設(shè)計(jì) Abstract 1946 birth of the world s first electronic computer which suggests that human created can be enhanced and part instead of the mental work tools It with humans in agriculture industrial society to create those is only a means of enhancing physical labor compared to a qualitative leap which laid a foundation for human into the information society Six years later in 1952 the computer technology application in machine tools was born in the United States the first CNC machine tool Since then traditional machine tools produced in recent years our country enterprise of nc machine tools share rise year by year in large and medium sized enterprises have more use a qualitative change Nearly half a century the CNC system has experienced two stages and the development of six generations Also common in small and medium sized enterprises and individual enterprises begin to use In the nc machine tools in addition to a small amount of machine tools used in FMS model integration mostly in single machine running state and some in the efficiency is not high management way backward state In recent years China s exports was bigger nc machine tool with CNC lathe CNC grinding machine numerical control special machine tools CNC bending machine CNC shearing machine CNC forming die casting machine such as the common machine tools have a drilling machine sawing machine slotting machine broaching machine combination machine tools hydraulic press Through the lathe main drive system of curriculum design causes the student to set up the correct design ideas and master the basic method of lathe main transmission system design Consolidate and deepen the theory knowledge the expanded aspect of knowledge and apply what they have learned the theory analysis and solve specific problems in the design work By machinery and equipment course design causes the student to the structure of the main transmission mechanism in forming lathe lathe parts design all kinds of scheme design calculation write technical documents and the expression of design ideas and so on to get basic training comprehensive Be familiar with the relevant standards and manuals and the use of the resources to foster a preliminary structural analysis and the ability to structure design and calculation Keywords main drive system transmission design dynamic design 目 錄 摘要 1 第一章 概述 1 1 1 國內(nèi)數(shù)控機(jī)床現(xiàn)狀 1 1 2 設(shè)計(jì)參數(shù) 1 第二章 參數(shù)的擬定 2 2 1 確定極限轉(zhuǎn)速 2 2 2 電機(jī)的選擇 2 第三章 傳動(dòng)設(shè)計(jì) 3 3 1 主傳動(dòng)方案擬定 3 3 2 傳動(dòng)結(jié)構(gòu)式 結(jié)構(gòu)網(wǎng)的選擇 3 3 3 轉(zhuǎn)速圖的擬定 3 第四章 主傳動(dòng)部分的改造和設(shè)計(jì) 6 4 1 主傳動(dòng)部分方案擬定 6 4 2 主傳動(dòng)部分設(shè)計(jì)改造設(shè)計(jì)計(jì)算 9 4 3 數(shù)控機(jī)床分級(jí)變速箱的設(shè)計(jì) 11 4 4 電磁離合器的設(shè)計(jì)計(jì)算 15 4 5 齒輪的結(jié)構(gòu)設(shè)計(jì) 16 4 6 帶輪結(jié)構(gòu)設(shè)計(jì) 17 4 7 傳動(dòng)軸間的中心距 17 4 8 軸承的選擇 17 第五章 動(dòng)力設(shè)計(jì) 18 5 1 傳動(dòng)軸的驗(yàn)算 18 5 2 齒輪效驗(yàn) 22 5 3 軸承的效驗(yàn) 23 第六章 結(jié)構(gòu)設(shè)計(jì)及說明 24 6 1 結(jié)構(gòu)設(shè)計(jì)的內(nèi)容 24 6 2 I 軸的設(shè)計(jì) 24 6 3 齒輪塊的設(shè)計(jì) 25 6 4 傳動(dòng)軸的設(shè)計(jì) 25 結(jié)論 27 參考文獻(xiàn) 28 致謝 29
