Latest Patents

Among his latest inventions, Taizou Wakayama has developed two distinctive thrust roller bearings. The first patent describes a thrust roller bearing featuring a plurality of radially arranged rollers and a pair of annular washers with raceway surfaces designed for optimal roller movement. Constructed from high-carbon chromium bearing steel, the rollers exhibit a specific surface roughness ranging from 0.01 to 0.10 in terms of Rvk and 0.01 to 0.08 in terms of Rk. Notably, one of the washers is composed of carbon steel, designed to optimize the raceway surface's compressive residual stress, measuring between -1400 MPa to -1000 MPa, while achieving a Vickers hardness between 850 to 900.

The second patent further refines the thrust roller bearing concept, delineating enhancements in the material composition, with the roller containing 1.1 mass % to 1.6 mass % of carbon and 0.1 mass % to 0.6 mass % of nitrogen near the surface. The bearing showcases a surface compressive residual stress of less than -900 MPa, a surface roughness of 0.01 to 0.10 in terms of Rvk and 0.01 to 0.08 in terms of Rk, and a Vickers hardness ranging from 860 to 980. This inventive approach optimizes performance and durability, significantly benefiting industries reliant on precision engineering.
