1、按照國標(biāo)GB/T17587.3-1998及應(yīng)用實(shí)例，滾珠絲杠（目前已基本取代梯形絲杠，已俗稱絲杠）是用來將旋轉(zhuǎn)運(yùn)動(dòng)轉(zhuǎn)化為直線運(yùn)動(dòng)；或?qū)⒅本€運(yùn)動(dòng)轉(zhuǎn)化為旋轉(zhuǎn)運(yùn)動(dòng)的執(zhí)行元件，并具有傳動(dòng)效率高，定位準(zhǔn)確等特點(diǎn)；         2、當(dāng)絲杠作為主動(dòng)體時(shí)，螺母就會(huì)隨絲杠的轉(zhuǎn)動(dòng)角度按照對(duì)應(yīng)規(guī)格的導(dǎo)程轉(zhuǎn)化成直線運(yùn)動(dòng)，被動(dòng)工件可以通過螺母座和螺母連接，從而實(shí)現(xiàn)對(duì)應(yīng)的直線運(yùn)動(dòng)。                                                                                            3、滾珠絲杠絲母間因無間隙，直線運(yùn)動(dòng)時(shí)精度較高，尤其在頻繁換向時(shí)無需間隙補(bǔ)償。滾珠絲杠絲母間摩擦力很小，轉(zhuǎn)動(dòng)時(shí)非常輕松。                                                                                                                                              4、滾珠絲杠與電機(jī)連接時(shí)中間必須加裝聯(lián)軸器以達(dá)到柔性連接。同步帶則可以直接用同步輪與電機(jī)出力軸連接。                                                                                                                                     &nb
