Worm Ball screw lift principle
Ball screw principle is the rotary motion into linear motion, or linear motion into rotary motion ideal product. Ball screw by the screw, nut and ball composition. Its function is to transform rotary motion into linear motion, which is a further extension and development of ball screws. The significance of this development is to change the bearing from rolling motion to sliding motion. Due to its small frictional resistance, ball screws are widely used in a variety of industrial equipment and precision instruments. Ball screw is the most commonly used transmission element in machine tools and precision machinery. Its main function is to convert rotary motion to linear motion or to convert torque to axial repetitive force with high precision, reversibility and high Efficiency characteristics.
