Title: Innovations of Hiroyasu Yoshihara
Introduction
Hiroyasu Yoshihara is a notable inventor based in Gunma, Japan. He has made significant contributions to the field of electromagnetic devices, holding two patents that showcase his innovative spirit and technical expertise. His work primarily focuses on improving the functionality and efficiency of electromagnetic clutches and coupling devices.
Latest Patents
Yoshihara's latest patents include an electromagnetic clutch and an electromagnetic coupling device with a noise damper. The electromagnetic clutch features a first rotation transmission portion, an annular field core, a rotation stop member, a second rotation transmission portion, an armature, and a spring member. The design ensures that the annular field core is supported by the first rotation transmission portion via a first bearing, which is housed in a hollow portion of the field core. The rotation stop member includes a flat portion that is fixed to the end of the field core opposite the armature, providing stability and efficiency. The electromagnetic coupling device incorporates a damper rubber member that mitigates sound generated during the attraction of the armature to the rotor. This innovation enhances user experience by reducing noise, as the spring constant of the damper rubber member is increased by enlarging the contact surface at the head portion of the torque transmission pin.
