滾珠絲桿螺紋槽與滾珠之間的微小間隙的狀態會對滾珠絲杠的特性有很大變化。在實際運用中我們通常也可以使用預緊來調整絲杠的精度要求。

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.

所謂預緊為了減小滾珠絲杠的間隙，提高剛性，使用一組滾珠，或者一對絲母沿軸向相互位移而施加在滾珠絲杠上的力。

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.

經?？唇z杠的選型目錄的設計師們會了解，在選型中我們會看軸向間隙，不同的種類和型號，軸向間隙是不同的，這里就是軸向間隙。

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.

關于絲杠的一些名詞解讀：

Interpretation of some terms of lead screw:

1、定位預緊：

1. Positioning preload:

用螺紋軸和滾珠之間的位置關系進行預緊的方法

Preloading method using the position relationship between threaded shaft and ball

2、導程改變方式：

2. Lead change mode:

在加工絲母的中螺紋溝槽時候通過改變導程，偏離出預緊量大小進行預緊式

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、墊片方式：

3. Gasket method:

在兩個絲母構造之間加入預緊量的墊圈或者墊片進行預緊的方法

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

4、定壓預緊：

4. Constant pressure preloading:

使用彈簧力的預緊方法

Preloading method using spring force

5、大號滾珠預緊方式：

5. Preloading method of large ball:

插入比螺紋溝槽形狀稍大的滾珠，通常在受力較大的狀態下進行預緊的方法

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