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.

所以在絲桿的運行中，絲桿本體，螺母本體，精細鋼珠，方向器等都會發(fā)生一定的磨損，這個時候絲桿和螺母會發(fā)生徑向間隙，導致精度下降，從這三個構(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，這就是簡略的絲桿維修方法，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.

滾珠絲桿的運用壽命的很長的，可是在實際的運用過程中，因為操作不當或許沒有及時的采納保養(yǎng)、保護措施，會使?jié)L珠絲桿發(fā)生提前老化的狀況發(fā)生，甚于，在升降機中進行正常運用，往往還會對精度發(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珠絲桿在正常運用時出現(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，并且還要對過盈量進行恰當?shù)臏p小，這樣能夠減少對絲桿的磨損，延長其運用壽命。滾珠絲桿是東西機械和精細機械上常運用的傳動元件。

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)運動轉(zhuǎn)換成線性運動，或?qū)⑴ぞ剞D(zhuǎn)換成軸向重復效果力，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、預壓片、反向器、防塵器組成。它的功用是將旋轉(zhuǎn)運動轉(zhuǎn)化成直線運動。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，滾珠絲桿的制造技能，能夠說是以水平的機械設(shè)備連貫生產(chǎn)出來的，特別是在研削、組裝、查看各工序的工廠環(huán)境方面，對溫度、濕度進行了嚴厲的控制，因為完善的質(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.

并且滾珠絲桿副因為是利用滾珠運動，所以啟動力矩小，不會出現(xiàn)滑動運動那樣的爬行現(xiàn)象，能確保完成準確的微進給，滾珠絲桿副能夠加予壓，因為予壓力可使軸向間隙達到負值，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.
