THK guide screw is a commonly used transmission component in tool machinery and precision machinery. Its main function is to convert rotary motion into linear motion or torque into axial repeated force, while also possessing the characteristics of high precision, reversibility, and high efficiency. Due to its small frictional resistance, THK guide screws are widely used in various industrial equipment and precision instruments.

滚珠丝杆由螺杆、螺母、钢球、预压片、反向器、防尘器组成。它的功能是将旋转运动转化成直线运动，这是艾克姆螺杆的进一步延伸和发展，这项发展的重要意义就是将轴承从滑动动作变成滚动动作。

The ball screw is composed of a screw, nut, steel ball, pre press plate, reverser, and dust collector. Its function is to convert rotational motion into linear motion, which is a further extension and development of the Aikem screw. The important significance of this development is to transform bearings from sliding motion to rolling motion.

滚珠螺杆特点1、摩擦损失小、传动效率高。

Features of ball screw: 1. Low friction loss and high transmission efficiency.

由于滚珠丝杆副的丝杠轴与丝杠螺母之间有很多滚珠在做滚动运动,所以能得到较高的运动效率。与过去的滑动丝杆副相比驱动力矩达到1/3以下,即达到同样运动结果所需的动力为使用滑动阿丝杠副的1/3。在省电方面很有帮助。

Due to the rolling motion of many balls between the screw shaft and the screw nut of the ball screw pair, high motion efficiency can be achieved. Compared with previous sliding screw pairs, the driving torque reaches less than 1/3, which means that the power required to achieve the same motion result is 1/3 of that required by using a sliding screw pair. It is very helpful in saving electricity.

2、精度高

2. High precision

滚珠丝杆副一般是用世界很高水平的机械设备连贯生产出来的，特别是在研削、组装、检查各工序的工厂环境方面,对温度、湿度进行了严格的控制，由于完善的品质管理体制使精度得以充分保证。

Ball screw pairs are generally produced using world-class mechanical equipment, especially in the factory environment of grinding, assembly, and inspection. Temperature and humidity are strictly controlled, and the precision is fully guaranteed due to a sound quality management system.

3、高速进给和微进给可能

3. High speed feed and micro feed may

滚珠丝杆副由于是利用滚珠运动,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。

The ball screw pair utilizes ball motion, so the starting torque is extremely small and there will be no crawling like sliding motion, ensuring accurate micro feed.

4、轴向刚度高

4. High axial stiffness

滚珠丝杆副可以加与预压,由于预压力可使轴向间隙达到负值,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,由于滚珠的斥力可使丝母部的刚性增强)。

The ball screw pair can be pre pressed, as the pre pressure can cause the axial clearance to reach a negative value, thereby obtaining higher rigidity (by applying pressure to the ball in the ball screw, when used in mechanical devices, the repulsive force of the ball can enhance the rigidity of the threaded part).

5、不能自锁、具有传动的可逆性

5. Cannot self lock and has reversible transmission
