  • Torsional vibration damping device
    Patent number: 9435397
    Abstract: The present invention relates to a torsional vibration damping device in which a contact site with an inertial mass can be lubricated effectively while reducing resistance of the inertial mass to oscillate. The vibration damping device includes a rotary member that is rotated by a torque, and an inertial mass that is oscillated by torque pulses. The inertial mass is held in a chamber formed on the rotary member liquid-tightly together with lubrication oil while being allowed to be oscillated by torque pulses in the rotational direction of the rotary member. An amount of the lubrication oil is adjusted in a manner such that the inertial mass will not be brought into contact with an oil film of the lubrication oil centrifugally adhering to a radially outer section of an inner face of the chamber.
