Latest Patents

Nogi's latest patents focus on the design and functionality of toroidal-type continuously variable transmissions. One of his patents describes a system where recessed grooves are formed on the inner and outer surfaces of a retainer. These grooves serve as lubricating oil flow passages, allowing lubricating oil to flow into pockets. The axial-direction depth of the recessed groove is expressed as H, while the circumferential-direction width is expressed as 2L, with the condition that 0.20 ≤ H/L ≤ 0.97 is satisfied. This innovation aims to prevent damage to the retainer incorporated into a thrust rolling bearing that supports a power roller, while also enhancing the lubricating efficiency of the thrust rolling bearing.

Another patent by Nogi presents a similar concept, where the recessed grooves are designed to improve lubrication. In this case, the axial-direction depth is expressed as H, and the circumferential-direction width is expressed as L, with the condition that 0.29 ≤ H/L ≤ 0.88 is satisfied. This design also aims to prevent damage to the retainer and improve the lubricating efficiency of the thrust rolling bearing.
