絲滾珠(zhū)絲杠是(shì)工具(jù)機械和(hé)精(jīng)密機械上(shàng)最常(cháng)使用(yòng)的(de)傳(chuán)動元(yuán)件，其主要(yào)功能是将(jiāng)旋轉運動(dòng)轉換成線性(xìng)運動，或将扭矩轉換成軸向(xiàng)反複(fú)作用(yòng)力，同時兼(jiān)具高精度、可逆(nì)性和高效(xiào)率(lǜ)的(de)特點。由于(yú)具有(yǒu)很小(xiǎo)的摩擦阻力，滾珠絲杠被廣泛應用于各(gè)種工業設(shè)備和(hé)精密儀器(qì)。

      滾珠(zhū)絲杠由(yóu)螺杆、螺(luó)母、鋼(gāng)球、預壓片、反向器、防塵器(qì)組成。

 滑作為此軸(zhóu)承(chéng)的周(zhōu)邊零部件(jiàn)，在使用所(suǒ)必(bì)要(yào)的絲(sī)杠支撐單元、螺母支(zhī)座、鎖緊螺(luó)母等也已被标(biāo)準化(huà)了，可(kě)供用(yòng)戶選(xuǎn)擇使用。廣(guǎng)泛應(yīng)用于機床(chuáng)，滾珠(zhū)的循環方(fāng)式有(yǒu)循環導管(guǎn)式、循(xún)環器(qì)式、端(duān)蓋式。

     wire ball screw is the most commonly used transmission element in tool and precision machinery. its main function is to convert rotating motion into linear motion, or to convert torque into axial repeated forces, with high precision, reversibility and high efficiency. because of its small friction resistance, ball screws are widely used in various industrial devices and precision instruments.

     the ball screw is made up of screw, nut, steel ball, pre pressing piece, reverser and dustproof device.

as the peripheral parts of this bearing, the necessary screw support unit, nut support and lock nut have also been standardized, which can be used by users. it is widely used in machine tools. the way of ball circulation is circular pipe type, circulator type and end cover type.
