Can the ball screw be repaired? Of course, it is possible. From a structural perspective, the ball screw is composed of the screw body, nut body, ball reverser, fine steel ball, and dust prevention equipment. In more complex cases, a vibration reduction and oil storage device is installed for the screw rod, which only serves as an auxiliary effect. Although the rolling friction is much smaller than sliding friction during operation, it still exists.

所以在絲桿的運(yùn)行中，絲桿本體，螺母本體，精細(xì)鋼珠，方向器等都會(huì)發(fā)生一定的磨損，這個(gè)時(shí)候絲桿和螺母會(huì)發(fā)生徑向間隙，導(dǎo)致精度下降，從這三個(gè)構(gòu)件來說，更換鋼珠，加大鋼珠的直徑，來調(diào)整絲桿的徑向間隙，是絲桿精度恢復(fù)，這就是簡(jiǎn)略的絲桿維修方法，所以說絲桿是能夠維修的。

So during the operation of the screw rod, there will be certain wear and tear on the screw rod body, nut body, fine steel balls, steering gear, etc. At this time, there will be radial clearance between the screw rod and the nut, leading to a decrease in accuracy. From these three components, replacing the steel balls and increasing the diameter of the steel balls to adjust the radial clearance of the screw rod is to restore the accuracy of the screw rod. This is a simple method of screw rod maintenance, so the screw rod can be repaired.

滾珠絲桿的運(yùn)用壽命的很長(zhǎng)的，可是在實(shí)際的運(yùn)用過程中，因?yàn)椴僮鞑划?dāng)或許沒有及時(shí)的采納保養(yǎng)、保護(hù)措施，會(huì)使?jié)L珠絲桿發(fā)生提前老化的狀況發(fā)生，甚至于，在升降機(jī)中進(jìn)行正常運(yùn)用，往往還會(huì)對(duì)精度發(fā)生一些影響。

The service life of the ball screw is very long, but in actual use, improper operation or failure to take timely maintenance and protection measures can lead to premature aging of the ball screw, and even normal use in elevators often has some impact on accuracy.

那么咱們今天來為咱們說一下怎么防止這種狀況的發(fā)生，為了防止?jié)L珠絲桿在正常運(yùn)用時(shí)出現(xiàn)合作過緊的狀況發(fā)生，咱們將軸承的徑向空地做一部分調(diào)整，并且還要對(duì)過盈量進(jìn)行恰當(dāng)?shù)臏p小，這樣能夠減少對(duì)絲桿的磨損，延長(zhǎng)其運(yùn)用壽命。滾珠絲桿是東西機(jī)械和精細(xì)機(jī)械上常運(yùn)用的傳動(dòng)元件。

So today we will talk about how to prevent this situation from happening. In order to prevent the ball screw from cooperating too tightly during normal use, we will make some adjustments to the radial clearance of the bearing and also appropriately reduce the interference. This can reduce the wear on the screw and extend its service life. Ball screw is a commonly used transmission component in East West machinery and fine machinery.

其主要功用是將旋轉(zhuǎn)運(yùn)動(dòng)轉(zhuǎn)換成線性運(yùn)動(dòng)，或?qū)⑴ぞ剞D(zhuǎn)換成軸向重復(fù)效果力，一起兼具高精度、可逆性和效率的特色。一般來說，滾珠絲桿的組成由螺桿、螺母、鋼球、預(yù)壓片、反向器、防塵器組成。它的功用是將旋轉(zhuǎn)運(yùn)動(dòng)轉(zhuǎn)化成直線運(yùn)動(dòng)。其中滾珠絲桿的螺母，根據(jù)鋼球的循環(huán)方法可分為：彎管式、循環(huán)器式、端蓋式。

Its main function is to convert rotational motion into linear motion, or to convert torque into axial repetitive force, which combines high accuracy, reversibility, and efficiency. Generally speaking, the composition of the ball screw is composed of a screw, nut, steel ball, pre pressing plate, reverser, and dust collector. Its function is to convert rotational motion into linear motion. The nuts of the ball screw can be divided into elbow type, circulator type, and end cover type according to the circulation method of the steel ball.

這三種循環(huán)方法的特長(zhǎng)，滾珠絲桿的制造技能，能夠說是以水平的機(jī)械設(shè)備連貫生產(chǎn)出來的，非常是在研削、組裝、查看各工序的工廠環(huán)境方面，對(duì)溫度、濕度進(jìn)行了嚴(yán)厲的控制，因?yàn)橥晟频馁|(zhì)量管理體制使精度得以充分確保。

The specialty of these three cycle methods, the manufacturing skills of ball screw, can be said to be produced continuously with horizontal mechanical equipment, especially in the aspects of grinding, assembly, and inspection of the factory environment of each process, strict control of temperature and humidity is carried out, because the perfect quality management system ensures accuracy fully.

并且滾珠絲桿副因?yàn)槭抢脻L珠運(yùn)動(dòng)，所以啟動(dòng)力矩小，不會(huì)出現(xiàn)滑動(dòng)運(yùn)動(dòng)那樣的爬行現(xiàn)象，能確保完成準(zhǔn)確的微進(jìn)給，滾珠絲桿副能夠加予壓，因?yàn)橛鑹毫墒馆S向間隙達(dá)到負(fù)值，從而得到較高的剛性。

And because the ball screw pair utilizes ball motion, the starting torque is small and there will be no crawling like sliding motion, which can ensure accurate micro feeding. The ball screw pair can apply pressure because the pressure can make the axial clearance reach a negative value, thereby obtaining higher rigidity.
