Title: **Akifumi Uryu: Innovator in Power Transmission Mechanisms**
Introduction
Akifumi Uryu, a notable inventor based in Kariya, Japan, has made significant contributions to the field of power transmission mechanisms. With a total of 8 patents to his name, Uryu's innovations have garnered attention for their engineering excellence and practical applications.
Latest Patents
Among Uryu's most recent innovations is a unique power transmitting mechanism designed to efficiently transmit power from an engine to the drive shaft of a compressor. This mechanism features a pulley supported by the compressor, coupled to the engine, and a hub connected to the drive shaft. Rollers are strategically positioned on the pulley, with elastic transmission arms positioned between the pulley and the hub. These arms are curved at their distal ends, allowing for effective power transmission when the rollers engage with them. Remarkably, if excessive torque causes the rollers to escape from the arms, power transmission is smoothly disconnected, showcasing Uryu's foresight in design.
Another noteworthy patent involves a power transmission mechanism that incorporates a first rotating member and a second rotating member, with an elastic member situated in between. The elastic member features a protrusion that contacts the first rotating member surface and is designed to taper gradually. As the first rotating member engages in motion, the elastic member deforms under compression, facilitating the required relative rotation between the two components. This innovative design enhances the mechanical efficiency of power transmission systems.
