The ball screw has the advantages of high transmission efficiency and accurate positioning. Therefore, it is more popular and liked as a transmission element in the production of industrial machinery. As we all know, it mainly converts linear motion into rotary motion or rotary motion into linear motion. The switching between the two is relatively stable and convenient.

滚珠丝杠的主要原理就是使得传动效率提高的同时，将定位更加准确了，下面详细说下它的原理。

The main principle of ball screw is to improve the transmission efficiency and make the positioning more accurate. Its principle is described in detail below.

，原本的梯形丝杆也就俗称上面讲的丝杆，已经基本上被滚珠丝杠取代了。主要原因就是，滚珠丝杠的原理是将旋转运动转化成直线运动、或者将直线运动转化成旋转运动的时候，作为传动元件的它能够在提高传动效率的同时，还能够准确的定位的缘故。

First of all, the original trapezoidal screw, also known as the screw mentioned above, has been basically replaced by ball screw. The main reason is that the principle of ball screw is that when the rotary motion is transformed into linear motion, or the linear motion is transformed into rotary motion, as a transmission element, it can not only improve the transmission efficiency, but also accurately locate.

其次，能够快速的实现对应的直线运动，比如说滚珠丝杠作为主动体的时候，螺母就能够跟随丝杆的转动角度来实现相应规格的转化工作。也就是这种情况下，被动的工件能够跟随螺母座或者是螺母进行连接，从而实现相对应的直线运动工作。

Secondly, it can quickly realize the corresponding linear motion. For example, when the ball screw is used as the driving body, the nut can follow the rotation angle of the screw to realize the conversion of corresponding specifications. That is, in this case, the passive workpiece can be connected with the nut seat or nut, so as to realize the corresponding linear motion.

说到底其实滚珠丝杠主要原理就是能够将旋转运动快速的转化成直线运动，在这两种运动之间可以使得切换相对容易。且能够保证在这二者之间的切换使用情况下，使得定位还能够准确无误。作为传动元件的滚珠丝杠表现出的效率和准确率都是非常不错的，能够适应很多情况下的使用。

In the final analysis, the main principle of ball screw is that it can quickly convert the rotating motion into linear motion, which can make the switching between the two motions relatively easy. And it can ensure that the positioning can be accurate under the switching use between the two. As a transmission element, the ball screw shows very good efficiency and accuracy, and can be used in many cases.
