Latest Patents

Kouji Nishii holds a patent for an "Automatic pressure control device for a ball screw." This invention involves varying fluid pressure to adjust the thickness of an elastic spacer between ball nuts of the ball screw. The thickness of the spacer plays a crucial role in determining the opposed axial forces applied to the ball nuts. During high-speed excursions of the screw, the pressure in the elastic spacer is reduced, which minimizes friction between the ball nuts and the screw. Conversely, when fine positioning is required for precise operations, the pressure in the elastic spacer is increased, urging the ball nuts apart to eliminate play in the ball screw. This innovative mechanism significantly improves the performance of ball screws in various applications.
