introduction：Working principle of ball screw nut？ The ball screw nut pair is a commonly used transmission device for converting rotary motion into linear motion in CNC machine tools。It replaces the sliding in the screw nut pair with the rolling of the ball，Low friction，It has good performance。 Make up：Mainly by the screw、nut、Balls and raceways（baller）、Nut seat, etc。 1.Working principle：The screw rod and nut are machined with spiral grooves，When fitted together, they form spiral raceways，And fill the raceway with balls。The ball rolls along the raceway，And through the return bead tube for a cyclic motion。Both ends of the bead tube also play the role of bead blocking，In case the ball falls off the raceway。 2．peculiarity： .High transmission efficiency：Mechanical efficiency up to92%~98%。 .Low friction：It mainly uses the rolling of the ball to replace the sliding of the ordinary screw nut pair。 .Axial clearance can be eliminated：Also due to the role of the ball，The rigidity of the system is improved。The gap can be eliminated a
