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 to buy a ball screw, lead screw and due to the reduction of inertia, the motor driving torque reduced; on the other hand because the screw The hollow portion of the coolant can flow through and reach the lower screw temperature only and therefore the temperature of the ball screw deputy can be better controlled. Ball advantages: 1. High transmission efficiency, friction loss is small Ball Which is good, the ball screw drive efficiency: 0.85 to 0.98, enables high-speed motion. 2. Transmission precision reverse gapless ball screw after tightening, to eliminate the axial clearance. 3. wear small, good precision ball screw factory, long service life. 4. reversible with motion can be rotary motion into linear motion, it can also convert linear motion into rotary motion, the screw and nut can make active member or follower.
