Ball Ball High reliability compared with other transmission machinery, hydraulic, ball screw ball screw shaft transmission failure rate is very low, maintenance is also relatively simple, just for general lubrication and dust. It can be operated without lubrication on special occasions. Ball to Ball preload preload to eliminate axial play ball screw factory, and further deformation of the axial load generated is minimized when conducting high-precision positioning to buy a ball screw, applying a pre-is general means. 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 to cool the 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.
