Title: Shunichi Tezuka: Innovator in Gear Technology
Introduction
Shunichi Tezuka is a notable inventor based in Azumino, Japan. He has made significant contributions to the field of gear technology, holding two patents that showcase his innovative spirit and technical expertise.
Latest Patents
One of his latest inventions is the "Silk hat-type strain wave gear device." This device features a crossed roller bearing that supports both an internal and an external gear, allowing for relative rotation. The design includes a first gap part sealed by an oil seal, while a second gap part communicates with a gear-side gap part outside the external gear. A bearing seal is incorporated to prevent excessive lubricant inflow from the gear-side gap into the second gap part, ensuring that excess lubricant can flow back to the gear-side gap without leaking through the oil seal.
Another significant patent is the "Apparatus for detecting position of rotation of motor." This invention utilizes a magnetic absolute sensor for a geared motor, which comprises a dipole magnet and hall elements. The dipole magnet is fixed within a hollow rotor shaft, and hall elements are strategically arranged to detect the magnet's position without increasing the motor shaft length. This innovative design ensures that the magnetic flux is effectively managed, preventing any adverse effects on the hall elements.
