The working process is mainly rely on the light bars and light bars on bearing friction force between a circumferential motion to realize the axial movement of the Key words: light bars drive , V type bearing , Friction type light bars Ball screw 目 錄 1. 引言 ............................................................. 5 滾珠絲杠 ............................................................................................................ 5 滾珠絲杠傳動原理 ....................................... 5 滾珠絲杠螺母副的結(jié)構(gòu)和原理 ............................. 5 滾珠絲杠 螺母副的特點(diǎn)是 ................................. 5 滾珠絲杠在實(shí)際應(yīng)用中的實(shí)例圖片展示 ..................... 6 . 普通絲杠(滑動)傳動 ..................................................................................... 6 滑動絲杠傳動副原理 ..................................... 6 滑動絲杠傳動原理和結(jié)構(gòu)圖 .............................. 6 滑動絲杠副的傳動特點(diǎn) .................................. 7 滑動絲杠副在實(shí)際應(yīng)用的實(shí)例圖片 ........................ 7 2. 傳動方案的設(shè)計(jì) ................................................... 7 傳動方案的總體結(jié)構(gòu) .......................................................................................... 7 傳動系統(tǒng)各個部分的選擇 ................................................................................ 8 電動機(jī)的選擇 .......................................... 8 減速器傳動比的分配 .................................... 9 光杠傳動部分的整體結(jié)構(gòu) ............................... 10 3. 光杠傳動原理、實(shí)際工作過程及校核計(jì)算 ........................... 11 光杠部分的工作原理 ...................................................................................... 11 光杠表面上橢圓曲線沿軸向移動分析 .............................................................. 12 機(jī)構(gòu)裝配關(guān)系與傳動原理 ............................................................................... 12 光杠特殊軸承 ............................................................................................... 14 光杠傳動部分實(shí)際工作過程 ............................................................................ 15 該光杠傳動系統(tǒng)的特點(diǎn) ................................................................................... 19
