A ball screw is a precision transmission device that converts rotational motion into linear motion. Its core components include the following parts:
Screw
The screw is the main part of the ball screw and is usually made of high-strength alloy steel with high rigidity and wear resistance. Its surface is machined with spiral grooves to guide the movement of the ball.
Nut
The nut is embedded with a ball circulation system and cooperates with the screw to achieve linear motion. The nut is also machined with a spiral groove that matches the screw to ensure that the ball can roll smoothly.
Steel Ball (Ball)
As an intermediate medium, the steel ball rolls between the spiral grooves of the screw and the nut to reduce friction and improve transmission efficiency. The cyclic movement of the ball is the key to achieving low friction and high-precision transmission.
Preload Plate
The preload plate is used to adjust the preload between the ball and the spiral groove to ensure that the ball screw can maintain stability and precision under high load.
Reverser
The function of the reverser is to guide the ball to circulate inside the nut, so that it returns from one end to the other end to form a closed loop. This design ensures the continuous movement of the ball.
Dust Collector
The dust collector is used to prevent external dust and impurities from entering the ball screw, protecting its precision structure and extending its service life.
Through the coordinated work of the above components, the ball screw achieves high efficiency and
