What is a ball screw? Also known as the ball screw, it is an ideal product to convert the rotary motion into the linear motion or the linear motion into the rotary motion. Ball screw consists of screw and nut! Its function is to transform the rotary motion into the linear motion, which is the further extension and development of the ball screw. The important significance of this development is to change the rolling action into the sliding action of the bearing. Due to its small friction resistance, ball screw is widely used in various industrial equipment.

滾珠絲桿的原料：1、按照國標GB/T17587.3-1998及應用實例，滾珠絲杠（已基本取代梯形絲桿，俗稱絲桿）是用來將旋轉運動轉化為直線運動；或將直線運動轉化為旋轉運動的執行元件，并具有傳動效率高，定位準確等

Raw materials of ball screw: 1. According to the national standard GB / t17587.3-1998 and application examples, ball screw (which has basically replaced trapezoidal screw rod, commonly known as screw rod) is used to convert rotary motion into linear motion, or convert linear motion into rotary motion, and has high transmission efficiency and accurate positioning

2、當滾珠絲杠作為主動體時，螺母就會隨絲桿的轉動角度按照對應規格的導程轉化成直線運動，被動工件可以通過螺母座和螺母連接，從而實現對應的直線運動。

2. When the ball screw is used as the driving body, the nut will be transformed into linear motion according to the corresponding specification lead with the rotation angle of the screw rod. The passive workpiece can be connected with the nut seat to realize the corresponding linear motion.

滾珠絲桿使用時要注意哪些事項？

What should be paid attention to when using ball screw?

1、潤滑

1. Lubrication

使用滾珠絲桿時，具有足夠的潤滑，如果潤滑不夠會發生與金屬接觸，導致摩擦與磨耗的增加，造成故障或是壽命短等。

When the ball screw is used, it has enough lubrication. If the lubrication is not enough, it will contact the metal, resulting in increased friction and wear, resulting in failure or short service life.

2、防壓

2. Anti pressure

滾珠絲桿與滾動軸承一樣當有混入異物或水分等時，磨損會增加，有時會導致破損。

Like the rolling bearing, the ball screw will wear more when there is foreign matter or moisture mixed in, and sometimes it will cause damage.

3、偏荷重

3. Partial load

當偏荷重現象發生時，將直接影響絲桿的壽命及噪音，且多隨著運轉不順的手感，若絲桿空載時與組裝后順暢度不同，除了注意絲桿本身的精度外，大多是組合精度不好產生偏荷重現象。

When the eccentric load occurs, it will directly affect the service life and noise of the screw rod, and most of them are due to the poor handle of the screw rod. If the smoothness of the screw rod is different from that after assembly when it is unloaded, in addition to paying attention to the accuracy of the screw rod itself, the phenomenon of unbalanced load is mostly caused by poor combination accuracy.
