Ball Screw Shaft - Global Industry Market Analysis Report 2020-2031

The ball screw shaft is a high-precision transmission element composed of a screw, a nut, a reversing device and a ball. It plays a key role in various precision machinery and automation equipment. It can convert rotary motion into linear motion or linear motion into rotary motion, and realize precise displacement control and power transmission.

Structurally, the screw is a slender shaft with a spiral groove, and the nut is mounted on the screw, and a spiral groove matching the screw is also provided inside. Many balls are evenly distributed between the spiral grooves of the screw and the nut. These balls, as rolling bodies, roll in the spiral grooves when the screw and the nut move relative to each other, greatly reducing the friction resistance. The reversing device is a key component for realizing the circular motion of the ball. When the ball rolls to a certain position between the screw and the nut, the ball can smoothly return to the starting end through the reversing device, forming a continuous circular motion and ensuring the continuity of the transmission.

Its working principle is based on the principle of spiral transmission and rolling friction. When the motor drives the screw to rotate, the nut cannot rotate with the screw due to the constraints of the external mechanism, and can only move linearly along the axial direction of the screw. In this process, the ball rolls between the spiral grooves of the screw and the nut, just like countless small ball bearings working, making the linear motion of the nut more stable and smooth, while also improving the transmission efficiency. Compared with the traditional sliding screw, the friction coefficient of the ball screw shaft is greatly reduced, generally only 1/20 - 1/40 of the sliding screw, which means that under the same load and motion conditions, the required driving force is smaller, the energy consumption is lower, and higher motion speed and precision can be achieved.

Ball screw shafts can be classified in many ways according to different standards. According to the cross-sectional shape of the thread raceway, it can be divided into single arc and double arc. The ball screw with a single arc raceway has a simple structure and low processing cost, but the contact stress between the ball and the raceway is relatively large; the double arc raceway can make the contact area between the ball and the raceway larger, the load-bearing capacity is stronger, and the operation is smoother, which is suitable for heavy-load and high-precision applications. According to the ball circulation method, it can be divided into two categories: internal circulation and external circulation. The balls of the internal circulation ball screw circulate inside the nut, and the circulation motion of the balls is realized through the reverse device. It has a compact structure and good rigidity, and is suitable for high-speed and high-precision transmission; the balls of the external circulation ball screw circulate in the circulation device outside the nut. The ball screw of this structure has a large load-bearing capacity and is suitable for heavy-load and long-stroke transmission.

Ball screw shafts have many significant features. The first is high precision. Through precise processing technology and strict quality control, ball screw shafts can achieve extremely high positioning accuracy and repeat positioning accuracy. The positioning accuracy can reach ±0.001mm, and the repeat positioning accuracy can reach ±0.0005mm, which meets the requirements of precision machinery and automation equipment for high-precision motion control. The second is high rigidity. Due to the large number of contact points between the balls, the screw and the nut, and the use of high-strength materials, the ball screw shaft has high rigidity and can withstand large axial loads and radial loads. It can still maintain stable performance under high-speed movement and heavy loads. Furthermore, its transmission efficiency is high. As mentioned above, its friction coefficient is small, which greatly improves the transmission efficiency, generally up to more than 90%. Compared with the sliding screw, it can effectively reduce energy loss and improve the working efficiency of the equipment. In addition, the ball screw shaft also has the advantages of long service life, smooth movement, and no creeping phenomenon, which can ensure the long-term stable operation of the equipment.

In the application field, ball screw shafts are widely used in various machine tools, such as CNC lathes, milling machines, machining centers, etc., to achieve precise movement of the workbench and feed control of the tool to ensure machining accuracy and surface quality. In industrial robots, ball screw shafts are used to drive the joints and arms of the robot to achieve precise movement and positioning of the robot, so that it can complete various complex tasks. In automated production lines, ball screw shafts are often used in conveying equipment, packaging equipment, testing equipment, etc. to achieve precise conveying and positioning of materials, improve production efficiency and automation. In addition, in the fields of aerospace, medical equipment, automobile manufacturing, etc., ball screw shafts also play an important role, providing key support for the technological development of these fields.
