對于無自動消除間隙機(jī)構(gòu)的螺母則應(yīng)及時更換螺母。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，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，要注意個支承的磨損情況，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。

在傳動時，滾珠與絲杠、螺母之間基本上是滾動摩擦.因此它具有以下優(yōu)點(diǎn)：滾珠絲杠副的傳動效率很高，可達(dá)92%?98%，是普通絲杠傳動的2?4倍，滾珠絲杠副的驅(qū)動力矩減少至滑動絲杠的1/3左右，發(fā)熱率大幅降低，溫升減小.并且在安裝滾珠絲杠副時采取以預(yù)緊方式消除軸向間隙等措施.使?jié)L珠絲杠副具有高的定位精度和重復(fù)定位精度。滾珠絲杠副采用質(zhì)量合金鋼制成，其滾道表面經(jīng)淬火熱處理后硬度高達(dá)60?似HRC，因此其實(shí)際壽命遠(yuǎn)高于滑動絲杠，從而彌補(bǔ)其制造成本高于滑動絲杠的不足點(diǎn)。滾珠絲杠副經(jīng)預(yù)緊后可以消除軸向間隙，提高系統(tǒng)的剛度。滾珠絲杠副消除了在傳動過程中可能出現(xiàn)的爬行現(xiàn)象，能夠?qū)崿F(xiàn)將旋轉(zhuǎn)運(yùn)動轉(zhuǎn)化為直線運(yùn)動或?qū)⒅本€運(yùn)動轉(zhuǎn)化為旋轉(zhuǎn)運(yùn)動并傳遞動力這兩種傳動方式。
