滾珠絲杠是將回(hui)轉(zhuan)運(yun)動(dong)(dong)轉(zhuan)化為直線運(yun)動(dong)(dong)，或將直線運(yun)動(dong)(dong)轉(zhuan)化為回(hui)轉(zhuan)運(yun)動(dong)(dong)的理想的產品。

滾(gun)珠絲(si)杠是工具機械和精密機械上最常(chang)使用(yong)(yong)的傳動(dong)元件，其主要功能是將(jiang)旋轉(zhuan)運(yun)動(dong)轉(zhuan)換成線性運(yun)動(dong)，或將(jiang)扭(niu)矩轉(zhuan)換成軸(zhou)向反復作用(yong)(yong)力，同時兼具高精度、可逆性和高效(xiao)率的特(te)點。由于具有很小的摩擦阻力，滾(gun)珠絲(si)杠被廣泛應(ying)用(yong)(yong)于各種工業設備和精密儀(yi)器。

滾(gun)(gun)珠絲杠由螺(luo)桿、螺(luo)母(mu)、鋼球、預壓片、反(fan)向器(qi)、防塵器(qi)組成(cheng)。它(ta)的(de)功能是(shi)將旋轉運(yun)動(dong)(dong)(dong)(dong)轉化(hua)(hua)成(cheng)直(zhi)線運(yun)動(dong)(dong)(dong)(dong)，這(zhe)是(shi)艾克姆螺(luo)桿的(de)進一步延伸和發(fa)(fa)展(zhan)(zhan)，這(zhe)項發(fa)(fa)展(zhan)(zhan)的(de)重要意義就是(shi)將軸承從滑動(dong)(dong)(dong)(dong)動(dong)(dong)(dong)(dong)作變成(cheng)滾(gun)(gun)動(dong)(dong)(dong)(dong)動(dong)(dong)(dong)(dong)作。當(dang)滾(gun)(gun)珠絲杠作為主動(dong)(dong)(dong)(dong)體時，螺(luo)母(mu)就會隨絲桿的(de)轉動(dong)(dong)(dong)(dong)角度按照對應規格的(de)導程轉化(hua)(hua)成(cheng)直(zhi)線運(yun)動(dong)(dong)(dong)(dong)，被動(dong)(dong)(dong)(dong)工件可以通過螺(luo)母(mu)座和螺(luo)母(mu)連接，從而實(shi)現對應的(de)直(zhi)線運(yun)動(dong)(dong)(dong)(dong)。
