Abstract

The invention discloses a rotating speed type damper which comprises a sleeve component, a screw rod component, a rotating disc component and a friction damping component; the screw rod component is arranged in the sleeve component in a relative movement manner; the rotating disc component is arranged in the sleeve component and comprises an inner stiffening plate, an elastic body and an overhanging plate which are connected in sequence, and the inner stiffening plate is connected with the screw rod component; the friction damping component comprises a friction layer and a mass block, the friction layer is arranged in the sleeve component, one end of the mass block is connected with the overhanging plate, and the other end of the mass block is provided with a friction plate forming a friction pair with the friction layer; and the screw rod component senses the action of vibration force and moves relative to the sleeve component, the rotating disc component drives the mass block to rotate synchronously, the rotating speed changes to enable the mass block to generate different centrifugal force, the pressure between the friction plate and the friction layer is changed, and thereforethe damper achieves variable output of damping force under the condition that the speed of an external load changes. The rotating speed type damper is simple in structure and high in damping efficiency, the cost can be effectively reduced, and the service life is prolonged.

Description

technical field [0001] The invention relates to the technical field of structure damping, in particular to a rotation speed type damper. Background technique [0002] The damper can effectively reduce the vibration response of the structure and greatly improve the seismic performance of the structure. However, the energy consumption of traditional dampers is not efficient, the energy conversion rate is low, and they cannot cope with the input of large earthquakes. In severe cases, the dampers may fail. Traditional dampers can no longer meet the performance requirements of modern structural vibration control. Contents of the invention [0003] The purpose of the present invention is to solve at least one of the technical problems existing in the prior art, and to provide a rotation velocity type damper capable of exerting better anti-seismic performance. [0004] According to the embodiment of the first aspect of the present invention, there is provided a rotation speed da...
