Latest Patents

Okuno's latest patents include an axial piston-type hydraulic rotary machine and a wet brake device. The axial piston-type hydraulic rotary machine features a nitriding layer formed on the front surface of a cylinder block. This design includes a compound layer-removed hole created by polishing techniques such as honing. Additionally, a tapered-state inclined surface is formed at the intersection of the compound layer-removed hole and the cylinder inlet side tapered surface.

The wet brake device consists of a series of rotating and non-rotating side brake disks arranged radially around a motor shaft. The non-rotating side brake disk is equipped with a frictional material that contains an oil groove. This configuration allows lubricant oil to flow efficiently, cooling the frictional engaging surface when braking force is applied.
