The invention discloses a piezoelectric stack-based vibration reduction ring device, and belongs to the field of design for vibration reduction devices. The vibration reduction ring device comprises an inner ring, an outer ring, an inner ring end cover, an outer ring end cover, piezoelectric stacks and butterfly-shaped connection elements, wherein one piezoelectric stack is connected to the longitudinal symmetry axis of each butterfly-shaped connection element; the butterfly-shaped connection elements are uniformly distributed in aligned grooves between the inner ring and the outer ring; and the inner ring end cover and the outer ring end cover are further arranged at the upper ends of the inner ring and the outer ring separately. According to the novel vibration reduction ring design disclosed by the invention, the vibration reduction ring is capable of effectively reducing vibration transferred to supporting by a transmission system through a shaft and a bearing by virtue of a piezoelectric shunt damping technology, and capable of effectively preventing the piezoelectric stacks from bearing tangential stress and torque, thereby prolonging the service lives of the piezoelectric stacks.
