With a total of 3 patents to his name, Saitou's work has advanced the efficiency and functionality of ball screw systems.
Latest Patents
Saitou's latest patents include a method for manufacturing a nut for ball screws and a ball screw mechanism. The first patent describes a method that forms a concave structure for a ball return passage directly on the inner circumferential surface of a nut blank through plastic working. This innovative approach avoids damage to the die and utilizes a die with a blank holder, cam driver, cam sliders, and a cylindrical member. The design allows for the formation of letter S shaped concaves, enhancing the manufacturing process.
The second patent outlines a ball screw mechanism and its assembly method. This design features a female screw groove that extends around the axis of the nut through 360 degrees or less. The sectional shape taken at right angles to the groove includes a circular arc portion and a rectilinear portion, facilitating easier removal of molds after molding. This innovation eliminates the need for a parting plane through the thread groove, allowing for a smoother and more efficient manufacturing process.
