Abstract

A ball screw assembly includes a screw shaft with a spiral groove, balls along the groove, a nut with the screw shaft relatively rotatable with the balls, and recirculation devices. The screw shaft end has a concave portion which extends along the axially direction and connecting the end of the groove. The tongue of the recirculation device is set in the concave and moving along the concave into the recirculation device concave of the nut. Thus, the ball nut and screw shaft are not separated, and the situation of the balls drop out will avoidable.
