According to the requirements of the main drive system of CNC machine tool and spindle power and torque characteristics, analysis of the design principle and method of mechanical and electrical connection and speed of main transmission system. Starting from the main drive system structure network, determine the optimum matching scheme of machine tool spindle power and torque characteristics, the calculation and verification of relevant motion parameters and dynamic parameters. Design steps and design method of this specification focuses on the main drive system of machine tool, according to the motion parameters have been determined by transmission center distance of expansion graph of the minimum as the goal, formulate transmission scheme transmission system, in order to obtain the optimal scheme and high design efficiency. In the main drive system of machine tool, in order to reduce the number of gears, simplify the structure, reduce the axial size, design method of the number of gear teeth is trial, join algorithm, design calculation of trouble and is not easy to find a reasonable. Through the research and analysis of the main drive system of triple slide gear characteristics, draw the part drawing and the spindle box expansion plan and section view.Key Words: classification of transmission; the transmission system; design; transmission; network structure; structure type; the module of gear; transmission ratio4目 錄摘 要 IIAbstract.III1 緒論.11.1 鉆床簡(jiǎn)介 11.2 鉆床的發(fā)展及趨勢(shì) 11.3 自動(dòng)攻絲機(jī)介紹 21.4 本課題設(shè)計(jì)內(nèi)容及要求 32 自動(dòng)攻絲機(jī)總體方案設(shè)計(jì).42.1 自動(dòng)攻絲機(jī)的動(dòng)力選擇 42.2 自動(dòng)攻絲機(jī)的驅(qū)動(dòng)方式 42.3 自動(dòng)攻絲機(jī)的動(dòng)力性能比較 52.4 自動(dòng)攻絲機(jī)動(dòng)力的計(jì)算與選擇 63 自動(dòng)攻絲機(jī)設(shè)計(jì).83.1 運(yùn)動(dòng)參數(shù)及轉(zhuǎn)速圖的確定 83.1.1 轉(zhuǎn)速范圍 .83.1.2 轉(zhuǎn)速數(shù)列 .83.1.3 確定結(jié)構(gòu)式 .93.1.4 確定結(jié)構(gòu)網(wǎng) .93.1.5 繪制轉(zhuǎn)速圖和傳動(dòng)系統(tǒng)圖 .103.2 確定各變速組此論傳動(dòng)副齒數(shù) 104 自動(dòng)攻絲機(jī)動(dòng)力計(jì)算.124.1 帶傳動(dòng)設(shè)計(jì) 124.2 計(jì)算轉(zhuǎn)速的計(jì)算 134.3 齒輪模數(shù)計(jì)算及驗(yàn)算 144.4 常用材料及熱處理 1454.5 傳動(dòng)軸最小軸徑的初定 194.6 主軸合理跨距的計(jì)算 205 主要零部件的選擇.225.1 軸承的選擇 225.2 鍵的規(guī)格 225.3 變速操縱機(jī)構(gòu)的選擇 226 校核.236.1 剛度校核 236.2 軸承壽命校核 247 結(jié)構(gòu)設(shè)計(jì)及說(shuō)明.267.1 結(jié)構(gòu)設(shè)計(jì)的內(nèi)容、技術(shù)要求和方案 267.2 展開圖及其布置 26結(jié) 論.27參考文獻(xiàn).28致 謝.29
