Ball screw is composed of screw, nut, steel ball, pre-pressing sheet, reverser and dust preventer. Its function is to transform rotational motion into linear motion, which is the further extension and development of Eckham screw. The important significance of this development is to change the bearing from sliding action to rolling action.

滾珠絲杠是工具機和精密機械上較常運用的傳動元件，其主要功用是將旋轉運動轉換成線性運動，或將扭矩轉換成軸向重復作用力，一起兼具高精度、可逆性和高功率的特色。因為具有很小的摩擦阻力，滾珠絲杠被廣泛應用于各種工業設備和精密儀器。

Ball screw is the most commonly used transmission element in tool machine and precision machinery. Its main function is to convert rotational motion into linear motion, or to convert torque into axial repetitive force. It has the characteristics of high precision, reversibility and high power. Because of its small friction resistance, ball screw is widely used in various industrial equipment and precision instruments.

滾珠絲杠的特色：

Characteristics of ball screw:

1、無側隙、剛性高

1. No backlash, high rigidity

滾珠絲杠副能夠加予壓，因為予壓力可使軸向空隙到達負值，進而得到較高的剛性（滾珠絲杠內通過給滾珠加予壓力，在實際用于機械裝置等時，因為滾珠的斥力可使絲母部的剛性增強）。

Ball screw pair can be pressurized, because the pressure can make the axial clearance reach a negative value, and then get a higher rigidity (ball screw by adding pressure to the ball, in practical use in mechanical devices, etc., because the repulsion of the ball can make the rigidity of the mother part of the wire increased).

2、高精度的確保

2. Guarantee of High Precision

滾珠絲杠副是用日本制造的世界較高水平的機械設備連接出產出來的？非常是在研削、拼裝、查看各工序的工廠環境方面，對溫度·濕度進行了嚴厲的操控，因為完善的品質管理體制使精度得以充分確保。

Ball screw pair is made in Japan with the world's highest level of mechanical equipment connected out of the output? Especially in the aspects of grinding, assembling and inspecting the factory environment of each process, the temperature and humidity are strictly controlled, because the perfect quality management system ensures the accuracy adequately.

 

3、微進給或許

3, micro feed perhaps.

 

 

滾珠絲杠副因為是運用滾珠運動，所以啟動力矩出彩小，不會出現滑動運動那樣的匍匐現象，能確保實現準確的微進給。

Ball screw pair because of the use of ball movement, so the starting moment is very small, will not appear the creeping phenomenon of sliding motion, can ensure the realization of accurate micro feed.

4、高速進給或許

4. High Speed Feed Perhaps

滾珠絲杠因為運動功率高、發熱小、所以可實現高速進給（運動）。

Ball screw can realize high speed feed (motion) because of its high power and low heat.

5、與滑動絲杠副比較驅動力矩為1/3

5. Compared with sliding screw pair, the driving moment is 1/3.

因為滾珠絲杠副的絲杠軸與絲母之間有許多滾珠在做翻滾運動，所以能得到較高的運動功率。與過去的滑動絲杠副比較驅動力矩到達1/3以下，即到達相同運動成果所需的動力為運用翻滾絲杠副的1/3。在省電方面很有幫助。

Because there are many balls rolling between the screw shaft and the screw mother of the ball screw pair, it can get higher motion power. Compared with the sliding screw pair in the past, the driving moment is less than 1/3, that is to say, the driving force needed to achieve the same results is 1/3 of the rolling screw pair. It is very helpful in saving electricity.
