Latest Patents
One of Akagi's latest patents involves a sophisticated one-way clutch design. This design features an inner race and an outer race that is driven in a specific direction. The outer race is equipped with multiple pockets on its inner circumference, which face the outer circumference of the inner race. These pockets contain rollers that are pressed in a specific direction by elastic members. The unique angular intervals between the pockets allow for a larger distance between the front end surface of the pocket and the threaded attachment hole, preventing rigidity reduction without increasing the outer race's diameter.
Another patent by Akagi focuses on an assembly that includes a sprag temporarily assembled to a retainer by a return spring. This assembly is designed to prevent the sprag from dropping out when depressed, thanks to a retaining member of a friction plate fixed to the retainer's end portion. The design also incorporates a lubrication passage that enhances functionality, ensuring that the assembly operates smoothly.
