Principle of operation
Ball Screws utilize the balls between the screw and the nut as a medium of motion to convert rotary motion into linear motion. As the screw rotates, the nut moves in the axial direction of the screw while the balls roll between the nut and screw and circulate in the raceways of the nut and screw. During this process, there is very little friction between the ball and the nut and screw, thus realizing efficient and precise motion transfer.
Structural features
Screw: The surface of the screw is processed with spiral grooves, the accuracy of which directly affects the transmission accuracy of the ball screw. The screw is generally made of high-strength alloy material to ensure its mechanical properties when subjected to high loads.
Nut: There is a channel for ball circulation in the nut, and linear motion is realized through the cooperation between the ball and the screw. The design and manufacturing process of the nut is crucial to the performance of the ball screw, which should ensure the stability and smoothness of the balls in the circulation process.
Ball: The ball is the core component of the ball screw and is usually made of high hardness and wear-resistant materials, such as bearing steel. The ball rolls between the screw and the nut and plays the role of transmitting force and movement.
Reversing device: It enables the circulation of the ball inside the nut, ensuring that the ball can continuously roll between the screw and the nut. The design and manufacturing quality of the reversing device has a direct impact on the operational efficiency and reliability of the ball screw
