Title: Innovations of Hirofumi Ogata
Introduction
Hirofumi Ogata is a notable inventor based in Kakegawa, Japan. He has made significant contributions to the field of mechanical engineering, particularly in the design of clutches and retainers. With a total of 11 patents to his name, Ogata's work showcases his innovative spirit and technical expertise.
Latest Patents
One of Ogata's latest patents is for an outer retainer for a one-way clutch. This outer retainer features a pair of annular portions facing each other in an axial direction, connected by a plurality of column members. The design includes window portions formed by the annular portions and column members, with an outward flange provided at one side end. The column member between window portions is cut, and the cut portion on the outward flange side is bent radially outward to create an elastic member. Additionally, paired cut-away portions are formed in predetermined portions of the outward flange, with the elastic member positioned between them. This innovative design allows for at least three window portions to be disposed between the elastic member and the adjacent cut-away portion in the peripheral direction. Furthermore, column members between paired cut-away portions are bent outward in the radial direction to enlarge the diameter.
Another significant invention by Ogata is a one-way clutch that includes an outer ring with a cylindrical wall on its inner circumference. The inner ring has cam surfaces formed on it, with rolling elements arranged between the outer and inner rings to facilitate torque transmission. Springs are used to bias the rolling elements, ensuring efficient operation. The inner ring is designed with recesses on its outer circumferential wall, creating lube-oil receiving and accumulating parts between the outer ring and the inner ring.
