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(jī)和精密機(jī)械上較常運(yùn)用的傳動元件，其主要功用是將旋轉(zhuǎn)運(yùn)動轉(zhuǎn)換成線性運(yùn)動，或?qū)⑴ぞ剞D(zhuǎn)換成軸向重復(fù)作用力，一起兼具高精度、可逆性和高功率的特色。因?yàn)榫哂泻苄〉哪Σ磷枇?，滾珠絲杠被廣泛應(yīng)用于各種工業(yè)設(shè)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(cè)隙、剛性高

1. No backlash, high rigidity

滾珠絲杠副能夠加予壓，因?yàn)橛鑹毫墒馆S向空隙到達(dá)負(fù)值，進(jìn)而得到較高的剛性（滾珠絲杠內(nèi)通過給滾珠加予壓力，在實(shí)際用于機(jī)械裝置等時(shí)，因?yàn)闈L珠的斥力可使絲母部的剛性增強(qiáng)）。

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(jī)械設(shè)備連接出產(chǎn)出來的？特別是在研削、拼裝、查看各工序的工廠環(huán)境方面，對溫度·濕度進(jìn)行了嚴(yán)厲的操控，因?yàn)橥晟频钠焚|(zhì)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(jìn)給或許

3, micro feed perhaps.

 

 

滾珠絲杠副因?yàn)槭沁\(yùn)用滾珠運(yùn)動，所以啟動力矩極小，不會出現(xiàn)滑動運(yùn)動那樣的匍匐現(xiàn)象，能確保實(shí)現(xiàn)準(zhǔn)確的微進(jìn)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(jìn)給或許

4. High Speed Feed Perhaps

滾珠絲杠因?yàn)檫\(yùn)動功率高、發(fā)熱小、所以可實(shí)現(xiàn)高速進(jìn)給（運(yùn)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(qū)動力矩為1/3

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

因?yàn)闈L珠絲杠副的絲杠軸與絲母之間有許多滾珠在做翻滾運(yùn)動，所以能得到較高的運(yùn)動功率。與過去的滑動絲杠副比較驅(qū)動力矩到達(dá)1/3以下，即到達(dá)相同運(yùn)動成果所需的動力為運(yùn)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.
