Latest Patents

Arakawa's latest patents include a unique shaft sealing structure that features a V-packing. This design incorporates a first guide bush attached to the inner circumference of the holder and a scraper positioned at the end of the holder. The V-packing is characterized by a thick-walled top portion, a thin-walled inner side skirt portion that extends diagonally inward, and a thin-walled outer side skirt portion that extends diagonally outward. The inner side skirt portion makes contact with the outer surface of the rod, while the outer side skirt portion abuts against the inner surface of the holder. This innovative design allows for free deformation of the inner and outer side skirt portions within the space formed between the first guide bush and the scraper.

Another patent by Arakawa involves a shaft sealing structure that consists of multiple stacked V-packings. Each V-packing is designed with a thick-walled annular top portion, a thin-walled inner side skirt portion, and a thin-walled outer side skirt portion. This configuration ensures that adjacent top portions abut against each other without interference from the inner and outer side skirt portions, enhancing the overall effectiveness of the sealing structure.
