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、冲突损失小、传动效能高

1. Small Conflict Loss and High Transmission Efficiency

由于滚珠丝杠副的丝杠轴与丝杠螺母之间有许多滚珠在做转动运动，所以能取得较高的运动效能。与以前的滑动丝杠副比较驱动力矩抵达1/3以下，即抵达十分运动结果所需的动力为使用滑动丝杠副的1/3。在省电方面很有协助。

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

滚珠丝杠副同样平凡是用全国较高水平的机械装备衔接临蓐进去的，分外特别是在研削、组装、查看各工序的工厂状态方面，对温度、湿度进行了严格的节制，由于的道德管理体制使精度得以足够保证。

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、高速进给和微进给能够或许

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

滚珠丝杠副由于是使用滚珠运动，所以启动力矩极小，不会出现滑动运动那样的爬行现象，能保证实现精确的微进给。

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、轴向刚度高

4. High axial stiffness

滚珠丝杠副能够或许加与预压，由于预压力能够使轴向旷地抵达负值，进而取得较高的刚性

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、不会自身上锁，但是能够或许互相传动的可逆性

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

以上几点就是滚珠丝杠的特色，就是由于滚珠丝杠的特色让人们觉得方便，所以他在机床上的用处十分的大。

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.
