The metal ribs on machine tools are often seen, and they are commonly used in machine tools, which is called ball screw. According to GB/T 17587.3-1998 and its application examples, ball screw is used to convert changing motion into linear motion, or to transform linear motion into implementing element of changing motion, and it has the characteristics of high transmission efficiency and accurate positioning.

1、沖突損失小、傳動效能高

1. Small Conflict Loss and High Transmission Efficiency

由于滾珠絲杠副的絲杠軸與絲杠螺母之間有許多滾珠在做轉(zhuǎn)動運(yùn)動，所以能取得較高的運(yùn)動效能。與以前的滑動絲杠副比較驅(qū)動力矩抵達(dá)1/3以下，即抵達(dá)十分運(yùn)動結(jié)果所需的動力為使用滑動絲杠副的1/3。在省電方面很有協(xié)助。

Because there are many balls rotating between the screw shaft and the screw nut of the ball screw pair, the ball screw pair can achieve higher efficiency. Compared with the previous sliding screw pairs, the driving moment is less than 1/3, that is to say, the power needed to reach the very motion result is 1/3 of the power needed to use the sliding screw pair. It is very helpful in saving electricity.

2、精度高

2. High accuracy

滾珠絲杠副同樣平凡是用全國較高水平的機(jī)械裝備銜接臨蓐進(jìn)去的，分外非常是在研削、組裝、查看各工序的工廠狀態(tài)方面，對溫度、濕度進(jìn)行了嚴(yán)格的節(jié)制，由于的道德管理體制使精度得以足夠保證。

Ball screw pair is also ordinary with the highest level of mechanical equipment in the country to join in, especially in grinding, assembly, inspection of the factory status of each process, the temperature and humidity are strictly controlled, due to the perfect moral management system to ensure adequate accuracy.

3、高速進(jìn)給和微進(jìn)給能夠或許

3. High-speed feeding and micro-feeding can be possible

滾珠絲杠副由于是使用滾珠運(yùn)動，所以啟動力矩出彩小，不會出現(xiàn)滑動運(yùn)動那樣的爬行現(xiàn)象，能保證實(shí)現(xiàn)準(zhǔn)確的微進(jìn)給。

Because ball screw pair uses ball movement, the starting moment is very small, and there will be no creeping phenomenon like sliding motion, which can ensure accurate micro feed.

4、軸向剛度高

4. High axial stiffness

滾珠絲杠副能夠或許加與預(yù)壓，由于預(yù)壓力能夠使軸向曠地抵達(dá)負(fù)值，進(jìn)而取得較高的剛性

Ball screw pair can be added or pre-pressed, because pre-pressure can make the axial open space reach the negative value, and then achieve higher rigidity.

5、不會自身上鎖，但是能夠或許互相傳動的可逆性

5. Not self-locking, but reversibility that can drive each other

以上幾點(diǎn)就是滾珠絲杠的特色，就是由于滾珠絲杠的特色讓人們覺得方便，所以他在機(jī)床上的用處十分的大。

The above points are the characteristics of ball screw, because the characteristics of ball screw make people feel convenient, so he is very useful in machine tools.
