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.

所以在丝杆的运行中，丝杆本体，螺母本体，精细钢珠，方向器等都会发生一定的磨损，这个时候丝杆和螺母会发生径向间隙，导致精度下降，从这三个构件来说，更换钢珠，加大钢珠的直径，来调整丝杆的径向间隙，是丝杆精度恢复，这就是简略的丝杆维修方法，所以说丝杆是能够维修的。

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.

滚珠丝杆的运用寿命的很长的，可是在实际的运用过程中，因为操作不当或许没有及时的采纳保养、保护措施，会使滚珠丝杆发生提前老化的状况发生，甚于，在升降机中进行正常运用，往往还会对精度发生一些影响。

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.

那么咱们今天来为咱们说一下怎么防止这种状况的发生，为了防止滚珠丝杆在正常运用时出现合作过紧的状况发生，咱们将轴承的径向空地做一部分调整，并且还要对过盈量进行恰当的减小，这样能够减少对丝杆的磨损，延长其运用寿命。滚珠丝杆是东西机械和精细机械上常运用的传动元件。

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.

其主要功用是将旋转运动转换成线性运动，或将扭矩转换成轴向重复效果力，一起兼具高精度、可逆性和效率的特色。一般来说，滚珠丝杆的组成由螺杆、螺母、钢球、预压片、反向器、防尘器组成。它的功用是将旋转运动转化成直线运动。其中滚珠丝杆的螺母，根据钢球的循环方法可分为：弯管式、循环器式、端盖式。

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.

这三种循环方法的特长，滚珠丝杆的制造技能，能够说是以水平的机械设备连贯生产出来的，特别是在研削、组装、查看各工序的工厂环境方面，对温度、湿度进行了严厉的控制，因为完善的质量管理体制使精度得以充分确保。

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.

并且滚珠丝杆副因为是利用滚珠运动，所以启动力矩小，不会出现滑动运动那样的爬行现象，能确保完成准确的微进给，滚珠丝杆副能够加予压，因为予压力可使轴向间隙达到负值，从而得到较高的刚性。

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.
