thk導軌絲杠是工具機械和精密機械上很常使用的傳動元件，其主要功能是將旋轉運動轉換成線性運動，或將扭矩轉換成軸向反復作用力，同時兼具高精度、可逆性和率的特點。由于具有很小的摩擦阻力，thk導軌絲杠被廣泛應用于各種工業設備和精密儀器。

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.

滾珠絲桿由螺桿、螺母、鋼球、預壓片、反向器、防塵器組成。它的功能是將旋轉運動轉化成直線運動，這是艾克姆螺桿的進一步延伸和發展，這項發展的重要意義就是將軸承從滑動動作變成滾動動作。

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.

滾珠螺桿特點1、摩擦損失小、傳動效率高。

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

由于滾珠絲桿副的絲杠軸與絲杠螺母之間有很多滾珠在做滾動運動,所以能得到較高的運動效率。與過去的滑動絲桿副相比驅動力矩達到1/3以下,即達到同樣運動結果所需的動力為使用滑動阿絲杠副的1/3。在省電方面很有幫助。

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

滾珠絲桿副一般是用世界很高水平的機械設備連貫生產出來的，特別是在研削、組裝、檢查各工序的工廠環境方面,對溫度、濕度進行了嚴格的控制，由于完善的品質管理體制使精度得以充分保證。

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、高速進給和微進給可能

3. High speed feed and micro feed may

滾珠絲桿副由于是利用滾珠運動,所以啟動力矩極小,不會出現滑動運動那樣的爬行現象,能保證實現精確的微進給。

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、軸向剛度高

4. High axial stiffness

滾珠絲桿副可以加與預壓,由于預壓力可使軸向間隙達到負值,進而得到較高的剛性(滾珠絲杠內通過給滾珠加予壓力,在實際用于機械裝置等時,由于滾珠的斥力可使絲母部的剛性增強)。

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、不能自鎖、具有傳動的可逆性

5. Cannot self lock and has reversible transmission
