Title: Keisuke Sakai: Innovator in Rotary Devices and Torque Technology

Introduction

Keisuke Sakai is a notable inventor based in Neyagawa, Japan. He has made significant contributions to the field of rotary devices and torque technology. With a total of 2 patents to his name, Sakai continues to push the boundaries of innovation in his industry.

Latest Patents

Sakai's latest patents include a rotary device and a torque fluctuation inhibiting device. The rotary device features two rotatable rotors and two stopper mechanisms that restrict relative rotation between the rotors. The first stopper mechanism includes a first protruding member with an elastic outer peripheral part, which contacts a first contact surface when a torsion angle reaches a specified angle. The second stopper mechanism operates similarly but includes a second protruding member with higher stiffness, engaging at a greater torsion angle.

His second patent, the torque fluctuation inhibiting device, comprises a mass body that is rotatable with a rotor. This device utilizes centrifugal elements that move radially under centrifugal force during rotation. When relative displacement occurs between the rotor and the mass body, cam mechanisms convert this force into a circumferential force to reduce the displacement, ensuring smoother operation.
