The ball screw consists of a screw, a nut, and a recirculating ball, and the motion is transmitted by the ball rolling between the screw and the nut.
As the screw rotates, the ball rolls in the threaded groove and is subjected to a forward squeezing force that pushes the nut along the axis.
Due to the small rolling friction coefficient of the balls and the relatively small friction loss, the ball screw has a high transmission efficiency and can achieve high-precision linear motion.
The main use of ball screws
Precise drive and positioning:The ball screw has the characteristics of high precision, high rigidity and low inertia, and is suitable for various occasions that require precise displacement control. In CNC machine tools, electronic manufacturing equipment, printing machinery and other fields, ball screws are widely used in key parts such as feed systems and workbench drives to ensure that the equipment can achieve high-precision processing and positioning.
High-speed transmission:Due to the high transmission efficiency and low frictional resistance of the ball screw, it is able to achieve high-speed rotation and linear motion. In equipment that pursues high productivity, such as high-speed stamping machines and high-speed packaging machinery, ball screws are a key component for efficient transmission.
Large load capacity:Ball screws have a high load-bearing capacity and rigidity, and are able to withstand large axial and radial forces. In heavy machinery, metallurgical equipment, petrochemical industry and other fields, ball screws are used to transmit large torques and bear heavy loads to ensure the stable operation of equipment.
Automation & Robotics:In automated production lines and robotics, ball screws are used to achieve precise linear and rotary motion. It ensures fast and accurate position control of the robot's end-effector, increasing the flexibility and flexibility of the production process.
Precision Measurement & Instrumentation:In precision measuring instruments and experimental equipment, ball screws are used to achieve high-precision displacement control and reading. It is widely used in microscopes, telescopes, optical instruments and other occasions that require high-precision displacement control.
