Title: Innovations by Jun Handa in Strain Wave Gearing
Introduction
Jun Handa, an innovative inventor based in Azumino, Japan, boasts an impressive portfolio of 22 patents. His groundbreaking work primarily focuses on strain wave gearing, where he has made significant advancements that enhance the compactness and efficiency of mechanical systems.
Latest Patents
One of Handa's latest patents involves a unique strain wave gearing design. This innovation features a pulley for transmitting rotation, positioned on the axial-direction first side relative to a cup-shaped externally toothed gear. The input shaft not only transmits input rotation to the wave generator but also serves as a support for both the pulley and the wave generator, supported at each end by bearings. This design ensures that the rotation-transmitting mechanism remains compact while maintaining robust support strength.
Another of Handa’s recent patents also centers on strain wave gearing. It comprises three components—an internally toothed gear, a cup-shaped externally toothed gear, and a wave generator. This invention includes a temporary-fixing jig that securely fastens to both the output shaft and the input shaft via temporary-fixing bolts. The jig allows for the three components to be maintained in an assembled state, streamlining the installation process by eliminating the need for position adjustments when attaching the gearing to a motor. By removing the jig post-installation, the space required for the overall mechanism is significantly reduced.
Career Highlights
Jun Handa has had a prominent career with impactful contributions, having worked with companies such as Harmonic Drive Systems Inc. and Nissan Motor Company Limited. His experience at these leading organizations has undoubtedly influenced his inventive approach in the field of mechanical engineering.
