Ball working principle and characteristics of the ball screw nut ball screw and nut due between ball screw into the ball which brand is good, so that between the ball screw and nut into rolling friction, which greatly reduces the Which small friction ball screw to improve the transmission efficiency. Ball screw and nut formed with a helical groove ball screw arc surface, will they fit together they form a spiral raceway, during which both the rotation and the ball rolling cycle. 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, where due to the oil or water can be cooled through the sale of screw ball screw, it is difficult to heat the screw itself, can effectively control the temperature, to achieve the purpose of accuracy and stability. 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.
