Title: Shigeyoshi Sakuraba: Innovator in Electromagnetic Technology
Introduction
Shigeyoshi Sakuraba is a notable inventor based in Kariya, Japan. He has made significant contributions to the field of electromagnetic technology, holding a total of 7 patents. His innovative designs have advanced the functionality and efficiency of various mechanical systems.
Latest Patents
One of Sakuraba's latest patents is an electromagnetic clutch. This device features an armature that comes into contact with an actuator due to magnetic attraction force. An outer plate is fixed to the armature, which rotates together with it. The inner hub, located between the armature and the outer plate, is movable along the rotation axis and is fixed to a driven device. A rubber member is placed between the inner hub and the outer plate, providing an urging force that non-linearly increases as the actuator and armature approach each other.
Another significant invention is a power transmission device that includes an electromagnet, rotor, armature, and hub. The hub connects the armature to the shaft of a drive-subject device. It consists of an outer hub coupled to the armature and a boss portion connected to the shaft. The inner side plate-shaped portion extends from the boss toward the outer side, with an inner plate placed between the outer hub and the inner side plate. This design allows for deformation or melting due to friction when the drive-subject device's shaft is locked during electromagnet energization.
