Ball screw structure: the ball screw nut is rotary motion into linear motion of the actuator used. It's rolling instead of sliding the ball screw nut in small friction, ball screw with a good performance of composition: Mainly by the screw, nut, ball and circulators, labyrinth seals, and other components hole . How it works: the screw and nut processing have arc spiral groove, when they suit together to form a spiral raceway Jiangsu ball screw, and filled with balls in the raceway. The ball is rolling along the raceway, and as the cycle of circular motion by a circulator. Circulator ends also played the role of stopper beads, to prevent the ball from falling out along the raceway. With the increase in speed machine Weinan ball screw, rail use is also to scroll transformed from sliding. In China, due to low machine speed and causes of Baoji ball screw manufacturing costs on the use of slide rail account for the majority, but the use of ball and roller guide rails in the sharp rise in the number of machines. Since rolling guide with high-speed, long life, plus the advantages of pre-press, easy installation, etc., with the improvement of performance and NC machine tool requirements, scroll increase rail use ratio is inevitable.
