Latest Patents

Hiroto Kawai holds a patent for a "Bearing device using felt member and method of manufacturing same." This invention features a bearing device for a rotary shaft that includes a porous sliding bearing and a felt ring fitted around it. Both the sliding bearing and the felt ring are filled with lubricant oil. The felt ring is crafted from needle-punched polypropylene fibers, which range from 0.4 to 20 micrometers in diameter. The manufacturing process involves shaping the polypropylene fibers into a felt sheet, heat-treating the sheet to remove fuzz, and punching it into a ring shape. The sliding bearing is designed with multiple grooves on its outer surface, which contact the felt ring. These grooves extend horizontally to prevent the lubricant oil from flowing downward.
