Title: Kazuyoshi Ogawa: Innovator in Friction Transmission and Chemical Polishing Solutions
Introduction
Kazuyoshi Ogawa is a notable inventor based in Kasugai, Japan. He has made significant contributions to the fields of mechanical engineering and materials science. With a total of 3 patents, Ogawa's work focuses on innovative solutions that enhance performance and efficiency in various applications.
Latest Patents
One of Ogawa's latest patents is a friction transmission unit designed to transmit power between input and output members through friction. This unit is capable of reducing losses while enabling large torque transmission. The design features a planar disk and a roller that contacts the upper surface of the disk. The roller's peripheral surface profile is expressed as z=a·sin h(bx), which ensures a constant contact stress distribution over approximately 80% of the contact region's width. This innovative profile prevents peak stresses at the edges, allowing for a monotonic decrease of stress in those areas.
Another significant patent is a brightening chemical polishing solution for hardened steel articles, such as carburized and quenched gears. This solution comprises hydrofluoric acid and hydrogen peroxide, with specific molar concentrations, and is designed to chemically polish steel articles effectively. The process includes a shot-peening step prior to polishing, enhancing the surface quality of the hardened steel.
