He has made significant contributions to the field of engineering, particularly in the development of devices that absorb torque variations. With a total of four patents to his name, Hosono's work showcases his expertise and innovative spirit.
Latest Patents
One of Hosono's latest patents is a torque variation absorbing device. This device includes a first flywheel and a second flywheel that are rotatable relative to each other via a ball bearing. A hysteresis mechanism is positioned between the two flywheels, allowing them to be biased in opposite directions. The design incorporates a ball inlet groove in both the outer and inner races of the ball bearing, facilitating the movement of balls that push the inner race away from the hysteresis mechanism. This innovative design prevents abrasion of the balls due to discontinuities in the inner race.
Another significant patent is an apparatus for absorbing torque vibration. This apparatus comprises inertial bodies, including first and second flywheels, along with a damper mechanism, torque limiting mechanism, and hysteresis mechanism interposed between the flywheels. The rotation is transmitted between the flywheels through these mechanisms, ensuring efficient operation. Resilient members are secured to spring seats, preventing excess compression and enhancing the device's reliability.
