滾珠絲杠是將回轉運(yun)(yun)動(dong)(dong)(dong)轉化為直(zhi)線(xian)運(yun)(yun)動(dong)(dong)(dong)，或將直(zhi)線(xian)運(yun)(yun)動(dong)(dong)(dong)轉化為回轉運(yun)(yun)動(dong)(dong)(dong)的理想的產品。

滾珠(zhu)絲杠是工(gong)具機械和精密(mi)(mi)機械上最常使用的傳動元件，其(qi)主要功(gong)能是將(jiang)旋轉(zhuan)運動轉(zhuan)換成線性運動，或將(jiang)扭(niu)矩轉(zhuan)換成軸向反(fan)復作用力，同時兼具高精度、可(ke)逆性和高效(xiao)率的特(te)點。由于(yu)具有很(hen)小的摩擦阻力，滾珠(zhu)絲杠被廣泛應用于(yu)各(ge)種工(gong)業(ye)設備和精密(mi)(mi)儀器。

滾珠絲(si)杠由(you)螺(luo)(luo)桿、螺(luo)(luo)母、鋼(gang)球、預壓片、反向器(qi)、防塵器(qi)組(zu)成。它的功能是(shi)(shi)將旋(xuan)轉(zhuan)運動(dong)(dong)(dong)轉(zhuan)化成直線(xian)(xian)運動(dong)(dong)(dong)，這是(shi)(shi)艾克姆螺(luo)(luo)桿的進一步延伸和發展，這項發展的重要意(yi)義(yi)就是(shi)(shi)將軸承從滑動(dong)(dong)(dong)動(dong)(dong)(dong)作變成滾動(dong)(dong)(dong)動(dong)(dong)(dong)作。當(dang)滾珠絲(si)杠作為主動(dong)(dong)(dong)體時，螺(luo)(luo)母就會(hui)隨(sui)絲(si)桿的轉(zhuan)動(dong)(dong)(dong)角(jiao)度按照對(dui)應規格的導(dao)程轉(zhuan)化成直線(xian)(xian)運動(dong)(dong)(dong)，被動(dong)(dong)(dong)工件可以通(tong)過螺(luo)(luo)母座和螺(luo)(luo)母連(lian)接，從而(er)實現(xian)對(dui)應的直線(xian)(xian)運動(dong)(dong)(dong)。

滾(gun)(gun)珠(zhu)(zhu)絲(si)(si)杠(gang)(gang)(gang)軸(zhou)承(cheng)為(wei)(wei)適應(ying)(ying)各種用(yong)(yong)途，提供了標準(zhun)化種類(lei)繁多(duo)的產品(pin)(pin)。廣泛應(ying)(ying)用(yong)(yong)于機床，滾(gun)(gun)珠(zhu)(zhu)的循(xun)環方(fang)式(shi)(shi)(shi)(shi)有(you)(you)循(xun)環導管式(shi)(shi)(shi)(shi)、循(xun)環器式(shi)(shi)(shi)(shi)、端蓋式(shi)(shi)(shi)(shi)。預壓(ya)方(fang)式(shi)(shi)(shi)(shi)有(you)(you)定位(wei)預壓(ya)（雙螺母方(fang)式(shi)(shi)(shi)(shi)、位(wei)預壓(ya)方(fang)式(shi)(shi)(shi)(shi)）、定壓(ya)預壓(ya)。可(ke)(ke)根據用(yong)(yong)途選(xuan)擇適當類(lei)型(xing)。絲(si)(si)桿有(you)(you)高精(jing)(jing)度研磨加(jia)(jia)(jia)工(gong)的精(jing)(jing)密滾(gun)(gun)珠(zhu)(zhu)絲(si)(si)杠(gang)(gang)(gang)（精(jing)(jing)度分為(wei)(wei)從(cong)CO-C7的6個等(deng)級）和經高精(jing)(jing)度冷軋加(jia)(jia)(jia)工(gong)成型(xing)的冷軋滾(gun)(gun)珠(zhu)(zhu)絲(si)(si)杠(gang)(gang)(gang)軸(zhou)承(cheng)（精(jing)(jing)度分為(wei)(wei)從(cong)C7-C10的3個等(deng)級）。另外(wai)，為(wei)(wei)應(ying)(ying)付用(yong)(yong)戶急需交貨的情況，還有(you)(you)已對軸(zhou)端部進行(xing)了加(jia)(jia)(jia)工(gong)的成品(pin)(pin)，可(ke)(ke)自由對軸(zhou)端部進行(xing)追加(jia)(jia)(jia)工(gong)的半成品(pin)(pin)及冷軋滾(gun)(gun)珠(zhu)(zhu)絲(si)(si)杠(gang)(gang)(gang)軸(zhou)承(cheng)。作為(wei)(wei)此軸(zhou)承(cheng)的周邊零部件，在(zai)使(shi)用(yong)(yong)所必(bi)要的絲(si)(si)杠(gang)(gang)(gang)支撐(cheng)單元、螺母支座、鎖緊(jin)螺母等(deng)也已被標準(zhun)化生產了，可(ke)(ke)供用(yong)(yong)戶選(xuan)擇使(shi)用(yong)(yong)。
