VIBRATION DAMPING DEVICE

摘要

A vibration damping device capable of reducing a change in an order frequency of a reciprocating motion of a pendulum resulting from eccentricity of rotational members therein. The vibration damping device 1 comprises a pendulum damping mechanism 11 having a mass 10 to dampen the torsional vibrations by an oscillating motion thereof resulting from the torsional vibrations. An inertial body 4 is arranged in the prime mover side of the rotary shaft 2 and 3, an elastic damping mechanism 5 is connected with a transmission side of the inertial body 4 in a power transmittable manner, a pendulum damping mechanism 11 is connected with the transmission side of the elastic damping mechanism 5 in a power transmittable manner, and a torque limiter mechanism 14 is connected with the transmission side of the pendulum damping mechanism 11 in a power transmittable manner.
