Ball screw and traditional screw are two common transmission methods in the field of mechanical transmission. In the choice of transmission mode, ball screw is often the better choice. This article will compare the ball screw with the traditional screw in terms of transmission efficiency, accuracy, life and application range, and explain why the ball screw is chosen.

First of all, the ball screw has obvious advantages in terms of transmission efficiency. The ball screw adopts the ball as the transmission medium, the contact area between the ball and the screw is small, the friction loss is less, so the transmission efficiency is high. The traditional screw uses the thread as the transmission medium, the contact area between the thread and the thread is large, the friction loss is large, and the transmission efficiency is relatively low. In some applications with high transmission efficiency requirements, such as machine tools, automation equipment and other fields, the choice of ball screw can improve transmission efficiency and improve the work efficiency of the equipment.

Secondly, the ball screw performs well in terms of accuracy. The coordination accuracy between the ball screw and the screw screw is high, and high positioning accuracy and repeated positioning accuracy can be achieved. However, due to the limitation of the manufacturing and matching accuracy of the traditional screw, the accuracy is relatively low. In some applications with high precision requirements, such as CNC machine tools, optical equipment and other fields, the choice of ball screw can improve the motion accuracy of the equipment and ensure product quality.

In addition, the life of the ball screw is longer. The ball screw uses rolling contact between the ball and the screw, which has less friction loss and therefore longer life than the sliding contact of the traditional screw. The life of the ball screw can generally reach tens of thousands of hours or even longer, while the life of the traditional screw is relatively short. In some applications with high service life requirements, such as industrial machinery and equipment, aerospace and other fields, the choice of ball screw can reduce the maintenance and replacement costs of equipment and improve the reliability of equipment.

Finally, the ball screw has a wider range of applications. Ball screw can be applied to high-speed, high-load, high-precision transmission requirements, and the application of traditional screw in these aspects is limited. Ball screw is widely used in machine tools, automation equipment, robots and other fields, while the traditional screw is more used in some low-speed, low-load transmission occasions.

In summary, the ball screw has obvious advantages compared with the traditional screw in transmission efficiency, accuracy, life and application range. In the selection of transmission mode, according to the specific application needs, the selection of ball screw can improve the work efficiency, motion accuracy and reliability of the equipment, reduce maintenance and replacement costs, and meet the transmission needs of different fields.
