This highlights the structural design requirements, under the basic requirements for ensuring the machine ,According to the principles of machine tool design, Development of institutional and structural , Streamlining of the machine tool sector, Strive to reduce production costs, No choice of materials resulting in high strength waste. 【 Keywords】 lather, Main drive system, Structure , Electric motor. 安徽建筑大學(xué)畢業(yè)設(shè)計(jì)論文 第 4 頁 共 53 頁 目錄 緒論 ................................................................................................................................ 6 ................................................................................................ 7 2. 主動參數(shù)的擬定 .................................................................................................... 8 確定傳動公比 ? .................................................................................................. 8 主電動機(jī)的選擇 .................................................................................................. 9 ....................................................................................................... 10 ....................................................................................................... 10 確定變速組及各變速組中變速副的數(shù)目 ........................................................ 10 結(jié)構(gòu)式的擬定 .................................................................................................... 11 結(jié)構(gòu)網(wǎng)的擬定 .................................................................................................... 11 各變速組的變速范圍及極限傳動比 ................................................................ 12 確定各軸的轉(zhuǎn)速 ................................................................................................ 13 繪制轉(zhuǎn)速圖 ........................................................................................................ 14 確定各變速組變速副齒數(shù) ................................................................................ 14 繪制變速系統(tǒng)圖 ................................................................................................ 16 ................................................................................................................... 17 結(jié)構(gòu)設(shè)計(jì)的內(nèi)容、技術(shù)要求和方案 ............................................................... 17 展開圖及其 布 置 ............................................................................................... 17 I軸（輸入軸）的設(shè)計(jì) ................................................................................... 17 齒輪塊設(shè)計(jì) ....................................................................................................... 18 傳動軸的設(shè)計(jì) ................................................................................................... 19 主軸組件設(shè)計(jì) ................................................................................................... 20 各部分尺寸的選擇 ..................................................................................... 20 主軸材料和熱處理 ..................................................................................... 20 主軸軸承 ..................................................................................................... 21 主軸與齒輪的連接 ..................................................................................... 22 潤滑與密封 ............................................................................................... 22 其他問題 ..................................................................................................... 22 ........................................................................................................... 23 帶輪的設(shè)計(jì) ........................................................................................................ 23 確 定各軸轉(zhuǎn)速 .................................................................................................... 26 傳動軸直徑的估算：確定各軸最小直徑 ........................................................ 27 鍵的選擇、傳動軸、鍵的校核 ........................................................................ 28 確定和校核 .......................................................................... 30 齒輪模數(shù)的確定： ............................................................................................ 30 安徽建筑大學(xué)畢業(yè)設(shè)計(jì)論文 第 5 頁 共 53 頁 齒輪的設(shè)計(jì) ........................................................................................................ 34 ..........................................................................................
