Latest Patents
One of Kotera's latest patents is a link plate for a silent chain. This link plate features a pair of teeth, each formed of an inside flank and an outside flank, along with a pair of pin apertures. The design aims to decrease the moment of force around a pin by reducing the length of a perpendicular drawn from the center of a pin aperture to the action line of the force. Additionally, the outside flank's pressure angle satisfies a specific inequality to lessen the force exerted on the chain.
Another significant patent is for a rocker joint silent chain that includes a joint pin thicker than the corresponding rocker pin. In this design, multiple link plates are interleaved and connected by connecting pins in a rocker joint. The joint pins are slightly longer and have a larger cross-sectional area than the rocker pins, enhancing the overall strength and durability of the silent chain.
