Description

Technical Field

[0001] The utility model relates to the technical field of ball screws, and more specifically to a ball screw locking device. Background Art

[0002] Ball screw, also known as ball screw or hollow screw, is an efficient transmission element widely used in tool machinery and precision machinery. Its main function is to convert rotational motion into linear motion, or torque into axial repetitive force, with the characteristics of high precision, reversibility and high efficiency. The core working principle of ball screw is based on the rolling of balls in the threaded raceway, and the transmission of motion is achieved through the cooperation with the threaded rod. The balls roll in the threaded raceway, converting rotational motion into rolling friction, thereby realizing the transmission of force. This working principle not only reduces the friction loss during transmission and improves the transmission efficiency, but also makes the positioning of the ball screw more accurate.
