滚珠丝杠预紧的原因是什么？

来源：http://www.jngongrun.com/ 日期：2021-12-04 发布人：

滚珠丝杆螺纹槽与滚珠之间的微小间隙的状态会对滚珠丝杠的特性有很大变化。在实际运用中我们通常也可以使用预紧来调整丝杠的精度要求。

The state of the small gap between the thread groove of the ball screw and the ball will greatly change the characteristics of the ball screw. In practice, we can also use preload to adjust the accuracy requirements of the lead screw.

所谓预紧为了减小滚珠丝杠的间隙，提高刚性，使用一组滚珠，或者一对丝母沿轴向相互位移而施加在滚珠丝杠上的力。

In order to reduce the clearance of the ball screw and improve the rigidity, the so-called pre tightening uses a group of balls or a pair of screw nuts to displace each other along the axial direction and apply the force on the ball screw.

经常看丝杠的选型目录的设计师们会了解，在选型中我们会看轴向间隙，不同的种类和型号，轴向间隙是不同的，这里就是轴向间隙。

Designers who often look at the selection catalog of lead screws will understand that in the selection, we will look at the axial clearance. The axial clearance is different for different types and models. Here is the axial clearance.

关于丝杠的一些名词解读：

Interpretation of some terms of lead screw:

1、定位预紧：

1. Positioning preload:

用螺纹轴和滚珠之间的位置关系进行预紧的方法

Preloading method using the position relationship between threaded shaft and ball

2、导程改变方式：

2. Lead change mode:

在加工丝母的中螺纹沟槽时候通过改变导程，偏离出预紧量大小进行预紧式

When machining the middle thread groove of the screw nut, the preload is carried out by changing the lead and deviating from the preload

3、垫片方式：

3. Gasket method:

在两个丝母构造之间加入预紧量的垫圈或者垫片进行预紧的方法

A method of pre tightening by adding a pre tightened washer or gasket between two screw nut structures

4、定压预紧：

4. Constant pressure preloading:

使用弹簧力的预紧方法

Preloading method using spring force

5、大号滚珠预紧方式：

5. Preloading method of large ball:

插入比螺纹沟槽形状稍大的滚珠，通常在受力较大的状态下进行预紧的方法

The method of inserting a ball slightly larger than the shape of the thread groove is usually preloaded under a large force
