滾珠(zhu)絲杠是將(jiang)回轉運動(dong)轉化為直線運動(dong)，或將(jiang)直線運動(dong)轉化為回轉運動(dong)的理想的產品。

滾珠絲(si)杠是工(gong)(gong)具(ju)(ju)機械和精密機械上(shang)最(zui)常使(shi)用(yong)的(de)傳動(dong)元件，其主要(yao)功能是將(jiang)旋轉(zhuan)運(yun)動(dong)轉(zhuan)換成(cheng)線性運(yun)動(dong)，或將(jiang)扭(niu)矩轉(zhuan)換成(cheng)軸向反復作用(yong)力，同(tong)時兼具(ju)(ju)高精度、可逆性和高效率(lv)的(de)特點。由于(yu)具(ju)(ju)有很小的(de)摩擦阻力，滾珠絲(si)杠被廣泛應用(yong)于(yu)各種工(gong)(gong)業設備和精密儀(yi)器。

滾(gun)珠(zhu)絲(si)杠(gang)由(you)螺(luo)桿(gan)、螺(luo)母(mu)(mu)、鋼球、預壓片、反向器(qi)、防塵器(qi)組成。它的(de)(de)功能是將(jiang)旋(xuan)轉(zhuan)運(yun)動(dong)(dong)(dong)(dong)(dong)轉(zhuan)化(hua)成直線(xian)運(yun)動(dong)(dong)(dong)(dong)(dong)，這是艾克姆螺(luo)桿(gan)的(de)(de)進一步延伸(shen)和發展(zhan)(zhan)，這項發展(zhan)(zhan)的(de)(de)重要意義就(jiu)是將(jiang)軸承從滑動(dong)(dong)(dong)(dong)(dong)動(dong)(dong)(dong)(dong)(dong)作變成滾(gun)動(dong)(dong)(dong)(dong)(dong)動(dong)(dong)(dong)(dong)(dong)作。當滾(gun)珠(zhu)絲(si)杠(gang)作為主動(dong)(dong)(dong)(dong)(dong)體時，螺(luo)母(mu)(mu)就(jiu)會隨絲(si)桿(gan)的(de)(de)轉(zhuan)動(dong)(dong)(dong)(dong)(dong)角度(du)按照對應規格的(de)(de)導程轉(zhuan)化(hua)成直線(xian)運(yun)動(dong)(dong)(dong)(dong)(dong)，被動(dong)(dong)(dong)(dong)(dong)工件可以通過螺(luo)母(mu)(mu)座和螺(luo)母(mu)(mu)連(lian)接，從而實現對應的(de)(de)直線(xian)運(yun)動(dong)(dong)(dong)(dong)(dong)。

滾(gun)珠(zhu)(zhu)絲杠(gang)軸(zhou)(zhou)承為(wei)適(shi)(shi)應各種用(yong)(yong)途，提供了(le)標準(zhun)化種類繁多的(de)(de)(de)產品(pin)(pin)。廣(guang)泛應用(yong)(yong)于(yu)機床，滾(gun)珠(zhu)(zhu)的(de)(de)(de)循(xun)(xun)環方式有(you)循(xun)(xun)環導管(guan)式、循(xun)(xun)環器式、端蓋式。預(yu)壓(ya)(ya)方式有(you)定(ding)位(wei)預(yu)壓(ya)(ya)（雙螺(luo)(luo)母方式、位(wei)預(yu)壓(ya)(ya)方式）、定(ding)壓(ya)(ya)預(yu)壓(ya)(ya)。可根據用(yong)(yong)途選(xuan)擇(ze)(ze)適(shi)(shi)當類型(xing)。絲桿有(you)高(gao)精度(du)(du)研磨(mo)加(jia)(jia)工(gong)的(de)(de)(de)精密(mi)滾(gun)珠(zhu)(zhu)絲杠(gang)（精度(du)(du)分(fen)為(wei)從CO-C7的(de)(de)(de)6個等級）和(he)經(jing)高(gao)精度(du)(du)冷軋加(jia)(jia)工(gong)成(cheng)型(xing)的(de)(de)(de)冷軋滾(gun)珠(zhu)(zhu)絲杠(gang)軸(zhou)(zhou)承（精度(du)(du)分(fen)為(wei)從C7-C10的(de)(de)(de)3個等級）。另外，為(wei)應付(fu)用(yong)(yong)戶急(ji)需(xu)交貨的(de)(de)(de)情(qing)況，還有(you)已對軸(zhou)(zhou)端部進行(xing)了(le)加(jia)(jia)工(gong)的(de)(de)(de)成(cheng)品(pin)(pin)，可自由對軸(zhou)(zhou)端部進行(xing)追加(jia)(jia)工(gong)的(de)(de)(de)半成(cheng)品(pin)(pin)及冷軋滾(gun)珠(zhu)(zhu)絲杠(gang)軸(zhou)(zhou)承。作為(wei)此軸(zhou)(zhou)承的(de)(de)(de)周邊零(ling)部件，在使(shi)用(yong)(yong)所必要的(de)(de)(de)絲杠(gang)支(zhi)撐單元、螺(luo)(luo)母支(zhi)座、鎖緊螺(luo)(luo)母等也已被標準(zhun)化生產了(le)，可供用(yong)(yong)戶選(xuan)擇(ze)(ze)使(shi)用(yong)(yong)。
