More Information
Summary:The present invention provides a vibration damping device capable of effectively damping the vibration during the rotation of rotor without disturbing the miniaturization of the peripheral structure of the rotor. The vibration damping device (10) is provided with a support member (20) fixedly secured to a rotor shaft (14) and a vibration damping member (22) nipped between a main mass (12) of the rotor and the support member (20). One axial end surface (26a) of a flange (26) of the support member (20) is positioned generally perpendicular to an axis of the shaft (14). The vibration damping member (22) is made of a visco-elastic material and fixedly connected, respectively, with one axial end surface (12a) of the main mass (12) and with the axial end surface (26a) of the support member (20) arranged in parallel and opposite to the former axial end surface (12a) apart therefrom at a distance. When the vibration occurs during the rotation of the rotor, the vibration damping member (22) nipped between the axial end surfaces (12a) and (26a) deforms in a visco-elastic manner to mitigate and rapidly damp the vibration.
