Latest Patents

Yoshito Katou's latest patents include a "Planetary gearing with flexible friction surfaces" and a "Method for manufacturing a friction speed change gearing." The first patent describes a friction speed change gearing that utilizes a plurality of planetary cylindrical rollers. These rollers move in a planetary manner along an annular space defined by inner and outer races, with a spider member engaged among the rollers. The innovation features flexible bearing shoes in the spider member, which enhance the lubricating oil film between the engaging surfaces of the roller and the spider member. The second patent outlines a method for manufacturing a friction speed change gearing that involves creating a first assembly with the inner race and planetary rollers, and a second assembly with the housing and outer race. This method includes forming a temperature differential between the two assemblies, allowing for uniform compression of the rollers due to thermal deformation.
