Ball screw is rotary motion into linear motion, or linear motion into rotary motion of the ideal product. ◎ ball screw by the screw, nut and ball composition. Its function is to convert rotary motion into linear motion, which is a further extension and development of ball screw, the significance of this development is to slide into the bearing from the rolling action action. ◎ ball screw drive element is most commonly used on machine tools and precision machinery, and its main function is to convert rotary motion into linear motion of the ball screw shaft, or to convert torque into axial force over and over again, while both high-precision , reversible and high efficiency characteristics. Hollow ball screw use of time for that? What are the advantages? A. Are generally more suitable for full-on ball screw machine temperature requirements more stringent. Hollow ball screw, since it is possible through the oil or water cooled screw supply ball screws, ball screws it is difficult to heat the screw itself, can effectively control the temperature of the ball screw, to achieve accuracy and stability purposes. B. hollow ball screw has the advantage of reduced weight, and therefore relatively easy to screw sagging under its own weight is too large, and due to the reduction of inertia of the screw, the motor driving torque reduced; the other hand, since the hollow portion of the screw can be the coolant flows through and achieve lower screw temperature only and therefore the temperature of the ball screw deputy can be better controlled.
