【正文】 r to bear, left to a gear transmission mechanism is plex, to expand the range of stepless speed regulation motor there are only two or three stagegear transmission system. It is fixed at the left end of the machine body, a spindle is arranged on the spindlebox (spindleis hollow, the laying of machining and machine line bar can be used not only for the longer the can also increase the rigidity of spindle),chuck,workpiece clamping fixture. Spindle box function is to support and drive spindle, the spindle drives the workpiece isdetermined according to the rotation speed of design rules is the main content of the main parameters of machine, draws up the transmission plan and the transmission system, the main parts of the calculationandchecking.. Key words: CA6140 machine tool spindle box parts transmission 茂名職業(yè)技術(shù)學(xué)院 3 目錄 一、 設(shè)計(jì)目的 ....................................................................4 二、 設(shè)計(jì)步 驟 ....................................................................4 1. 運(yùn)動(dòng)設(shè)計(jì) ..................................................................4 已知條 件 ..................................................................4 結(jié)構(gòu)分析 式 ................................................................4 繪制轉(zhuǎn)速 圖 ................................................................5 繪制傳動(dòng)系統(tǒng) 圖 ............................................................7 2. 動(dòng)力設(shè)計(jì) ..................................................................8 確定各軸轉(zhuǎn)速 ..................................................................8 帶傳動(dòng)設(shè) 計(jì) ................................................................9 各傳動(dòng)組齒輪模數(shù)的確定和校核 . ...........................................10 3. 齒輪強(qiáng)度校核 ............................................................11 校核 a 傳動(dòng)組齒輪 . ......................................................12 校核 b 傳動(dòng)組齒輪 ........................................................14 校核 c 傳動(dòng)組齒輪 ........................................................15 4. 主軸撓度的校核 ...........................................................15 確定各軸最小直徑 .........................................................15 軸的校核 .................................................................15 5. 主軸最佳跨距的確定 .......................................................16 選擇軸頸直徑 ,軸承型號(hào)和最佳跨距 ..........................................16 求軸承剛度 ...............................................................16 6. 各傳動(dòng)軸支承處軸承的選擇 ..............................................
