Title: Yasunori Tokuno: Innovator in Hydrodynamic Bearing Technology
Introduction
Yasunori Tokuno is a notable inventor based in Saijyo, Japan. He has made significant contributions to the field of hydrodynamic bearing devices, with a total of 5 patents to his name. His work focuses on enhancing the efficiency and durability of motor systems.
Latest Patents
Among his latest patents are the hydrodynamic bearing device and the dynamic pressure bearing motor. The hydrodynamic bearing device aims to achieve power savings, reduce the time required for stabilizing rotation, and enhance durability during startup and halting of the motor. This is accomplished by accelerating the circulation of lubricant near a flange while maintaining low torque loss. The design features a flange fixed to one end of a shaft, with a step portion provided on the inner surface of a sleeve. This innovative configuration allows for a narrow gap between the flange and the step portion, optimizing performance.
The dynamic pressure bearing motor incorporates a magnet designed to trap abraded powder, which is strategically placed in the connecting passage between the sleeve and the hydrodynamic bearing motor. The use of austenitic stainless steel for the shaft, sleeve, thrust flange, and thrust main plate enhances the cleaning process. This design prevents the flow of abraded powder to the outside, ensuring a cleaner and more efficient operation.
