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. 安徽建筑大學畢業(yè)設計論文 第 3 頁 共 53 頁 目錄 緒論 ................................................................................................................................ 5 ................................................................................................ 6 2. 主動參數(shù)的擬定 .................................................................................................... 7 確定傳動公比 ? .................................................................................................. 7 主電動機的選擇 .................................................................................................. 8 ......................................................................................................... 9 ......................................................................................................... 9 確定變速組及各變速組中變速副的數(shù)目 .......................................................... 9 結構式的擬定 .................................................................................................... 10 結構網(wǎng)的擬定 .................................................................................................... 10 各變速組的變速范圍及極限傳動比 ................................................................ 11 確定各軸的轉速 ................................................................................................ 12 繪制轉速圖 ........................................................................................................ 13 確定各變速組變速副齒數(shù) ................................................................................ 13 繪制變速系統(tǒng)圖 ................................................................................................ 15 ................................................................................................................... 16 結構設計的內容、技術要求和方案 ............................................................... 16 展開圖及其 布 置 ............................................................................................... 16 I軸（輸入軸）的設計 ................................................................................... 16 齒輪塊設計 ....................................................................................................... 17 傳動軸的設計 ................................................................................................... 18 主軸組件設計 ................................................................................................... 19 各部分尺寸的選擇 ..................................................................................... 19 主軸材料和熱處理 ..................................................................................... 19 主軸軸承 ..................................................................................................... 20 主軸與齒輪的連接 ..................................................................................... 21 潤滑與密封 ............................................................................................... 21 其他問題 ..................................................................................................... 21 ........................................................................................................... 22 帶輪的設計 ........................................................................................................ 22 確定各軸轉速 .................................................................................................... 25 傳動軸直徑的估算：確定各軸最小直徑 ........................................................ 26 鍵的選擇、傳動軸、鍵的校核 ........................................................................ 27 .......................................................................... 29 齒輪模數(shù)的確定： ............................................................................................ 29 安徽建筑大學畢業(yè)設計論文 第 4 頁 共 53 頁 齒輪的設計 ........................................................................................................ 33 ..........................................................................................
