Latest Patents

Watanabe's latest patents focus on advanced thrust roller bearing designs. The first patent describes a thrust roller bearing that includes a plurality of radially arranged rollers and a pair of annular washers with raceway surfaces on which the rollers roll. The raceway surfaces are designed to face each other, and the roller is constructed from high-carbon chromium bearing steel. It features a surface roughness of 0.01 to 0.10 in terms of Rvk and 0.01 to 0.08 in terms of Rk. Additionally, at least one of the washers is made of carbon steel, with a surface compressive residual stress of -1400 MPa to -1000 MPa, and a Vickers hardness of 850 to 900.

The second patent also pertains to a thrust roller bearing, which similarly includes radially arranged rollers and annular washers. In this design, the roller is made of high-carbon chromium bearing steel, containing 1.1 mass % to 1.6 mass % of carbon and 0.1 mass % to 0.6 mass % of nitrogen within 0.1 mm from the surface. The surface compressive residual stress is less than -900 MPa, with a surface roughness of 0.01 to 0.10 in terms of Rvk and 0.01 to 0.08 in terms of Rk. The Vickers hardness of the surface ranges from 860 to 980, and at least one of the washers is made of carbon steel, with raceway surface roughnesses of 0.05 to 0.20 in terms of Rvk and 0.08 to 0.15 in terms of Rk.
