滾珠絲杠(gang)是將(jiang)回轉(zhuan)(zhuan)運動轉(zhuan)(zhuan)化為直(zhi)線運動，或將(jiang)直(zhi)線運動轉(zhuan)(zhuan)化為回轉(zhuan)(zhuan)運動的理想(xiang)的產品(pin)。

滾(gun)珠絲杠是工具機(ji)械和(he)精(jing)(jing)密(mi)機(ji)械上最常(chang)使用的(de)傳動(dong)元件，其主(zhu)要功能是將(jiang)旋轉運動(dong)轉換成(cheng)線性運動(dong)，或將(jiang)扭矩轉換成(cheng)軸向反復作(zuo)用力(li)，同時(shi)兼具高精(jing)(jing)度、可逆性和(he)高效率(lv)的(de)特點。由(you)于具有很小(xiao)的(de)摩擦阻力(li)，滾(gun)珠絲杠被廣泛應用于各種工業設(she)備和(he)精(jing)(jing)密(mi)儀器。

滾珠(zhu)絲杠由螺(luo)桿、螺(luo)母(mu)(mu)、鋼(gang)球、預壓片、反向器、防塵器組成。它的(de)功(gong)能是(shi)將旋轉(zhuan)運(yun)(yun)動(dong)(dong)(dong)(dong)(dong)轉(zhuan)化成直(zhi)線運(yun)(yun)動(dong)(dong)(dong)(dong)(dong)，這(zhe)(zhe)是(shi)艾克(ke)姆螺(luo)桿的(de)進一步(bu)延伸和(he)發(fa)展(zhan)，這(zhe)(zhe)項發(fa)展(zhan)的(de)重要意義就(jiu)是(shi)將軸承從滑動(dong)(dong)(dong)(dong)(dong)動(dong)(dong)(dong)(dong)(dong)作變成滾動(dong)(dong)(dong)(dong)(dong)動(dong)(dong)(dong)(dong)(dong)作。當(dang)滾珠(zhu)絲杠作為主動(dong)(dong)(dong)(dong)(dong)體時，螺(luo)母(mu)(mu)就(jiu)會隨絲桿的(de)轉(zhuan)動(dong)(dong)(dong)(dong)(dong)角度按照對應規格的(de)導(dao)程轉(zhuan)化成直(zhi)線運(yun)(yun)動(dong)(dong)(dong)(dong)(dong)，被動(dong)(dong)(dong)(dong)(dong)工件可(ke)以通過螺(luo)母(mu)(mu)座和(he)螺(luo)母(mu)(mu)連接，從而實現對應的(de)直(zhi)線運(yun)(yun)動(dong)(dong)(dong)(dong)(dong)。

滾珠(zhu)絲杠(gang)軸(zhou)(zhou)(zhou)承(cheng)為適應各種用(yong)(yong)(yong)途，提供了標準(zhun)化種類(lei)繁(fan)多(duo)的(de)(de)(de)產品(pin)(pin)。廣泛應用(yong)(yong)(yong)于機(ji)床，滾珠(zhu)的(de)(de)(de)循環方式有(you)循環導管(guan)式、循環器式、端蓋式。預(yu)壓(ya)(ya)方式有(you)定(ding)位預(yu)壓(ya)(ya)（雙(shuang)螺母(mu)方式、位預(yu)壓(ya)(ya)方式）、定(ding)壓(ya)(ya)預(yu)壓(ya)(ya)。可(ke)根據用(yong)(yong)(yong)途選擇適當類(lei)型。絲桿有(you)高精(jing)度研(yan)磨加(jia)工(gong)(gong)的(de)(de)(de)精(jing)密滾珠(zhu)絲杠(gang)（精(jing)度分(fen)為從(cong)CO-C7的(de)(de)(de)6個(ge)等(deng)級）和(he)經高精(jing)度冷軋加(jia)工(gong)(gong)成型的(de)(de)(de)冷軋滾珠(zhu)絲杠(gang)軸(zhou)(zhou)(zhou)承(cheng)（精(jing)度分(fen)為從(cong)C7-C10的(de)(de)(de)3個(ge)等(deng)級）。另外，為應付用(yong)(yong)(yong)戶急需(xu)交貨的(de)(de)(de)情況，還(huan)有(you)已(yi)(yi)對軸(zhou)(zhou)(zhou)端部(bu)(bu)進行了加(jia)工(gong)(gong)的(de)(de)(de)成品(pin)(pin)，可(ke)自由對軸(zhou)(zhou)(zhou)端部(bu)(bu)進行追加(jia)工(gong)(gong)的(de)(de)(de)半成品(pin)(pin)及(ji)冷軋滾珠(zhu)絲杠(gang)軸(zhou)(zhou)(zhou)承(cheng)。作(zuo)為此軸(zhou)(zhou)(zhou)承(cheng)的(de)(de)(de)周邊(bian)零部(bu)(bu)件，在(zai)使用(yong)(yong)(yong)所(suo)必要的(de)(de)(de)絲杠(gang)支(zhi)撐單元、螺母(mu)支(zhi)座、鎖緊螺母(mu)等(deng)也已(yi)(yi)被標準(zhun)化生產了，可(ke)供用(yong)(yong)(yong)戶選擇使用(yong)(yong)(yong)。
