滾珠絲(si)杠是將(jiang)回轉運動(dong)轉化(hua)為(wei)直(zhi)線(xian)運動(dong)，或將(jiang)直(zhi)線(xian)運動(dong)轉化(hua)為(wei)回轉運動(dong)的理想(xiang)的產品。

滾(gun)珠(zhu)絲(si)杠是工(gong)具(ju)機械和(he)精(jing)(jing)密(mi)機械上(shang)最(zui)常使用的(de)(de)傳(chuan)動(dong)元件(jian)，其(qi)主要功能是將(jiang)旋轉運動(dong)轉換(huan)成線(xian)性運動(dong)，或將(jiang)扭(niu)矩(ju)轉換(huan)成軸向反復作用力，同時兼具(ju)高精(jing)(jing)度、可(ke)逆性和(he)高效率(lv)的(de)(de)特點。由(you)于具(ju)有很小(xiao)的(de)(de)摩擦阻力，滾(gun)珠(zhu)絲(si)杠被廣泛應(ying)用于各種工(gong)業設備和(he)精(jing)(jing)密(mi)儀器(qi)。

滾珠絲杠由螺(luo)桿、螺(luo)母、鋼球、預(yu)壓片(pian)、反向器、防塵器組成(cheng)(cheng)。它的功能(neng)是(shi)將旋轉(zhuan)運動(dong)(dong)(dong)(dong)(dong)(dong)轉(zhuan)化(hua)成(cheng)(cheng)直線運動(dong)(dong)(dong)(dong)(dong)(dong)，這(zhe)是(shi)艾克姆(mu)螺(luo)桿的進一(yi)步(bu)延伸(shen)和發展(zhan)，這(zhe)項發展(zhan)的重(zhong)要意(yi)義就是(shi)將軸承從滑動(dong)(dong)(dong)(dong)(dong)(dong)動(dong)(dong)(dong)(dong)(dong)(dong)作(zuo)變成(cheng)(cheng)滾動(dong)(dong)(dong)(dong)(dong)(dong)動(dong)(dong)(dong)(dong)(dong)(dong)作(zuo)。當滾珠絲杠作(zuo)為主(zhu)動(dong)(dong)(dong)(dong)(dong)(dong)體時，螺(luo)母就會隨(sui)絲桿的轉(zhuan)動(dong)(dong)(dong)(dong)(dong)(dong)角度按照對應規格(ge)的導程轉(zhuan)化(hua)成(cheng)(cheng)直線運動(dong)(dong)(dong)(dong)(dong)(dong)，被動(dong)(dong)(dong)(dong)(dong)(dong)工件可以通過螺(luo)母座和螺(luo)母連接(jie)，從而(er)實(shi)現(xian)對應的直線運動(dong)(dong)(dong)(dong)(dong)(dong)。

滾(gun)珠絲(si)杠(gang)軸(zhou)(zhou)承為(wei)(wei)適應(ying)各種用(yong)(yong)(yong)途，提供了(le)標(biao)準化種類(lei)繁多(duo)的(de)(de)產品(pin)。廣泛應(ying)用(yong)(yong)(yong)于機床(chuang)，滾(gun)珠的(de)(de)循環(huan)方式(shi)有循環(huan)導管式(shi)、循環(huan)器式(shi)、端(duan)蓋式(shi)。預(yu)壓方式(shi)有定位預(yu)壓（雙螺(luo)母方式(shi)、位預(yu)壓方式(shi)）、定壓預(yu)壓。可(ke)(ke)根據(ju)用(yong)(yong)(yong)途選(xuan)擇適當類(lei)型(xing)。絲(si)桿有高(gao)精(jing)度研磨加(jia)(jia)工(gong)的(de)(de)精(jing)密滾(gun)珠絲(si)杠(gang)（精(jing)度分為(wei)(wei)從CO-C7的(de)(de)6個(ge)等(deng)級）和經高(gao)精(jing)度冷軋(ya)(ya)加(jia)(jia)工(gong)成型(xing)的(de)(de)冷軋(ya)(ya)滾(gun)珠絲(si)杠(gang)軸(zhou)(zhou)承（精(jing)度分為(wei)(wei)從C7-C10的(de)(de)3個(ge)等(deng)級）。另外，為(wei)(wei)應(ying)付(fu)用(yong)(yong)(yong)戶(hu)急(ji)需交貨的(de)(de)情(qing)況，還(huan)有已(yi)對軸(zhou)(zhou)端(duan)部進行了(le)加(jia)(jia)工(gong)的(de)(de)成品(pin)，可(ke)(ke)自由對軸(zhou)(zhou)端(duan)部進行追加(jia)(jia)工(gong)的(de)(de)半成品(pin)及冷軋(ya)(ya)滾(gun)珠絲(si)杠(gang)軸(zhou)(zhou)承。作為(wei)(wei)此軸(zhou)(zhou)承的(de)(de)周邊零部件，在使用(yong)(yong)(yong)所必要的(de)(de)絲(si)杠(gang)支(zhi)撐(cheng)單(dan)元、螺(luo)母支(zhi)座(zuo)、鎖緊螺(luo)母等(deng)也已(yi)被標(biao)準化生產了(le)，可(ke)(ke)供用(yong)(yong)(yong)戶(hu)選(xuan)擇使用(yong)(yong)(yong)。
