Latest Patents

Noguchi's sole patent, centered on a refined sprocket tooth profile, addresses critical issues such as noise reduction and impact during the meshing process of roller chains. His design features a meticulously structured engaging flank, comprising three distinct arc portions: the seating, impact, and distal sections. Each section is defined by well-established radii and arc centers, enhancing the sprocket's functionality. Additionally, the disengaging flank adheres to a modified version of the JIS standard that involves a smaller sprocket pitch compared to the roller chain pitch. This innovative design allows for a gradual change in roller velocity at the impact point, significantly diminishing impact levels and minimizing polygonal effects.
