Latest Patents

Yamada's latest patents include innovative designs for sliding members and plain bearings. The sliding member patent describes a slide member that features a base material and an overlay. This overlay consists of multiple regions with varying thicknesses, including a sliding-surface side that interacts with a counter element. The material used for the overlay is composed of several crystal planes, with the orientation index differing between the sliding-surface side and the base-material side.

In his plain bearing patent, Yamada has developed a design that enhances fatigue resistance and anti-seizure properties while maintaining embeddability. This plain bearing comprises a bearing alloy layer, an intermediate layer, and an overlay layer, all sequentially formed on the inner surface of a back metal. The inner surface of the bearing alloy layer features a textured uneven surface with recesses and protrusions, promoting the embedding of foreign particles introduced between the sliding surfaces.
