一般而言，轉(zhuǎn)造級滾珠螺桿除了在導(dǎo)程誤差的定義及幾何公差與研磨級滾珠絲杠（滾珠螺桿）有所不同外，一樣可使用相同的預(yù)壓方式來消除軸向余隙。冷軋絲杠（滾珠螺桿）的螺帽型式及尺寸可參考研磨級螺帽資料來選購。冷軋絲杠（滾珠螺桿）的生產(chǎn)不同于研磨級使用研磨方式，而是使用滾牙方式來生產(chǎn)螺桿。相較于傳統(tǒng)導(dǎo)螺桿，轉(zhuǎn)造級滾珠螺桿不僅在使用上具有低摩擦、運(yùn)轉(zhuǎn)順暢的優(yōu)點(diǎn)，同時(shí)供貨迅速且價(jià)格低廉。|滾珠絲杠-微進(jìn)給可能，由于是利用滾珠運(yùn)動|所以啟動力矩極小，常州滾珠絲杠的安裝，常州滾珠絲杠的安裝，常州滾珠絲杠的安裝,不會出現(xiàn)滑動運(yùn)動那樣的爬行現(xiàn)象|能保證實(shí)現(xiàn)精確的微進(jìn)給。滾珠絲杠-無側(cè)隙、剛性高，滾珠絲杠可以加予壓|由于予壓力可使軸向間隙達(dá)到負(fù)值|進(jìn)而得到較高的剛性(滾珠絲杠內(nèi)通過給滾珠加予壓力|在實(shí)際用于機(jī)械裝置等時(shí)|由于滾珠的斥力可使絲母部的剛性增強(qiáng))。

對于無自動消除間隙機(jī)構(gòu)的螺母則應(yīng)及時(shí)更換螺母。1)絲杠的磨損絲杠的螺紋部分在全長上的磨損很不均勻，經(jīng)常使用的部分，磨損較大,如臥式車床縱向進(jìn)給絲杠在靠近主軸箱部分磨損較嚴(yán)重，而靠近床尾部分則極少磨損。這使絲杠螺紋厚度大小不一,螺距不等，導(dǎo)致絲杠螺距累計(jì)誤差超過公差,造成機(jī)床進(jìn)給機(jī)構(gòu)進(jìn)刀量不準(zhǔn)，直接影響工作臺或刀架的運(yùn)動精度。當(dāng)絲杠螺距誤差太大而不能滿足加工精度要求時(shí)，可用重新加工螺紋并配作螺母的方法修復(fù)或更換新的絲杠副。2)絲杠的支撐和托架絲杠在徑向承受的載荷小，轉(zhuǎn)速低，多采用銅套做支承;而軸向支承的精度和剛度比徑向支承要求高的多,多采用高精度推力軸承。由于加工和裝配精度的限制,往往存在著調(diào)整螺母端面與螺紋軸心線垂直度的誤差,導(dǎo)致推力集中在軸承的局部，使磨損加劇，成為絲杠發(fā)生抖動的主要原因。因此在對絲杠副進(jìn)行定期檢查時(shí)，要注意個(gè)支承的磨損情況，保證螺母端面與墊圈均勻接觸。從而保證絲杠軸向支承的精度要求。對于水平安裝的長絲杠，常用托架支承絲杠,以免絲杠由于自重產(chǎn)生小撓現(xiàn)象。在使用過程中，托架不可避免要被磨損。因此也要定期檢查，以便調(diào)整或修理。

D：滾珠絲杠副的公稱直徑，也為滾珠中心處的直徑（mm）;N：滾珠絲杠副的極限轉(zhuǎn)速（rpm）。DN值得限制不是直徑越小則轉(zhuǎn)速越高，因?yàn)槭紫却_定的進(jìn)給速度，當(dāng)通過進(jìn)給速度計(jì)算的絲杠轉(zhuǎn)速太高可通過增加導(dǎo)程以降低轉(zhuǎn)速，來滿足DN值要求。 </p> <p> 滾珠絲杠選型 </p> <p> 1：確定滾珠絲杠導(dǎo)程，根據(jù)電機(jī)額定轉(zhuǎn)速和X向滑板比較大速度.來選。 </p> <p> 2：計(jì)算滾珠絲桿的載荷及轉(zhuǎn)速，滾動導(dǎo)軌承重時(shí)的動和靜摩擦，工作臺的工作質(zhì)量和阻力，導(dǎo)軌和滑塊密封摩擦的阻力。 </p> <p> 3：預(yù)期工作時(shí)間和機(jī)床的選擇 </p> <p> <br
