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.

滚珠丝杠是工具机和精密机械上较常运用的传动元件，其主要功用是将旋转运动转换成线性运动，或将扭矩转换成轴向重复作用力，一起兼具高精度、可逆性和高功率的特色。因为具有很小的摩擦阻力，滚珠丝杠被广泛应用于各种工业设备和精密仪器。

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.

滚珠丝杠的特色：

Characteristics of ball screw:

1、无侧隙、刚性高

1. No backlash, high rigidity

滚珠丝杠副能够加予压，因为予压力可使轴向空隙到达负值，进而得到较高的刚性（滚珠丝杠内通过给滚珠加予压力，在实际用于机械装置等时，因为滚珠的斥力可使丝母部的刚性增强）。

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、高精度的确保

2. Guarantee of High Precision

滚珠丝杠副是用日本制造的世界较高水平的机械设备连接出产出来的？特别是在研削、拼装、查看各工序的工厂环境方面，对温度·湿度进行了严厉的操控，因为完善的品质管理体制使精度得以充分确保。

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、微进给或许

3, micro feed perhaps.

 

 

滚珠丝杠副因为是运用滚珠运动，所以启动力矩极小，不会出现滑动运动那样的匍匐现象，能确保实现准确的微进给。

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、高速进给或许

4. High Speed Feed Perhaps

滚珠丝杠因为运动功率高、发热小、所以可实现高速进给（运动）。

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

5、与滑动丝杠副比较驱动力矩为1/3

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

因为滚珠丝杠副的丝杠轴与丝母之间有许多滚珠在做翻滚运动，所以能得到较高的运动功率。与过去的滑动丝杠副比较驱动力矩到达1/3以下，即到达相同运动成果所需的动力为运用翻滚丝杠副的1/3。在省电方面很有帮助。

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.
