Title: Innovations of Yoshihiro Demura
Introduction
Yoshihiro Demura is a notable inventor based in Iwata, Japan. He has made significant contributions to the field of mechanical engineering, particularly in the development of rotation transmission devices and one-way clutches. With a total of 2 patents to his name, his work showcases innovative solutions that enhance the functionality and efficiency of mechanical systems.
Latest Patents
Demura's latest patents include a rotation transmission device and a one-way clutch. The rotation transmission device features inner and outer rings with a two-way clutch in between. An electromagnetic clutch is integrated to selectively engage and disengage the two-way clutch. This design includes an electromagnet with a core secured to a flange, which is positioned within a recess of a stationary member. A snap ring prevents the flange from dislodging, while an elastic member ensures proper axial positioning of the electromagnet. This innovative approach reduces the spring force and cost associated with the elastic member.
The one-way clutch proposed by Demura is designed to be low in surface pressures and highly durable. It consists of an inner ring with a cylindrical outer surface and an outer ring that defines a wedge-shaped space. A ring-shaped wedge member is placed within this space, featuring a cylindrical outer surface and an inner surface with a center of curvature that is offset. A resilient member biases the wedge member to engage with the cylindrical surfaces of the inner and outer rings, allowing for efficient torque transfer when the inner ring rotates in one direction.
