Title: Kei Shibayama: Innovator in Starter Technology
Introduction
Kei Shibayama is a notable inventor based in Nagoya, Japan. He has made significant contributions to the field of starter technology for internal combustion engines. With a total of 3 patents to his name, Shibayama's work showcases his innovative approach to engineering challenges.
Latest Patents
One of Shibayama's latest patents is a "Starter with one-way clutch for cranking internal combustion engine." This invention includes an electric motor, an output shaft, and a one-way clutch that transmits rotational torque from the motor to the output shaft. The design incorporates a clutch-outer driven by the electric motor, a clutch-inner spline-coupled to the output shaft, and rollers positioned between the two components. Notably, a portion of the clutch-inner serves as an inner ring of a ball bearing, enhancing the lubricating function without the need for an original inner ring.
Another significant patent is the "Starter with stopper on clutch inner portion of one-way clutch." In this design, the one-way clutch transmits motor rotation to the output shaft, featuring female helical splines on the clutch inner portion. A stopper is positioned at the front end of the female helical splines, which engages with male helical splines on the output shaft. This mechanism restricts relative rotation and stops the axial movement of the output shaft when the splines come into contact.
