Ball screw is the most commonly used transmission element in tool machinery and precision machinery. Its main function is to convert rotational motion into linear motion, or convert torque into axial repeated force. It also has the characteristics of high precision, reversibility and high efficiency.

Characteristics of ball screw transmission: The ball screw transmission mechanism uses the ball between the screw and the nut as an intermediate element, changing the sliding friction transmission between the screw and the nut into rolling friction transmission. The ball screw and nut are both equipped with arc-shaped spiral grooves. The two arc-shaped spiral grooves are combined to form a raceway. There are many balls installed in the raceway, so there is rolling friction between the screw and the nut. Ball retainers are installed at both ends of the spiral groove of the nut to block it, and there is a return pipe to allow the balls to roll out of the nut body from one end of the spiral groove, and then return to the other end of the raceway along this return pipe. In this way, when the ball screw rotates relative to the nut to perform linear motion feed transmission, the balls continuously roll in the spiral raceway.

As a precise and labor-saving transmission mechanism, it is widely used in ball screws of precision machine tools and CNC machine tools.
