Title: The Innovative Mind of Masashi Ochi
Introduction
Masashi Ochi, a prominent inventor based in Tokyo, Japan, has made significant contributions to the field of gear manufacturing. With an impressive portfolio of 15 patents, Ochi specializes in advanced machining methods tailored for internal gears, showcasing his expertise in optimizing manufacturing processes.
Latest Patents
Among his latest innovations is an internal gear grinding method designed to efficiently grind internal gears with arc-shaped teeth. This method utilizes a threaded grindstone with a barrel shape that aligns with the arc shape of the gear's teeth. By synchronizing the rotation of both the internal gear and the grindstone at a specific axis intersection angle, Ochi has achieved a notable reduction in grinding time.
Another critical innovation is his internal gear machining method and corresponding device. This invention employs a barrel-shaped threaded grinding wheel, where a Numerical Control (NC) device aids in correcting tooth profile errors. By adjusting various parameters such as the radial and lateral positions of the grinding wheel, as well as its turning angle, Ochi's method significantly reduces errors in the tooth face, enhancing the precision of machined gears.
