Damping generation method through torsion type lead extrusion and damper thereof

Abstract

The invention relates to a damping generation method through torsion type lead extrusion, which comprises the following steps: taking a closed cavity; filling a damping material in the closed cavity; penetrating a central rotating shaft into the closed cavity and forming rotating connection with the closed cavity; and arranging a flange on the central rotating shaft and embedding the flange into the damping material. A torsion type lead extrusion damper comprises the closed cavity filled with lead and the central rotating shaft, wherein the central rotating shaft passes through the closed cavity; and the flange is arranged on the central rotating shaft. Aiming at the characteristic that the traditional lead damper utilizes an energy consumption mechanism with relative translation displacement, the invention provides a novel torsion type lead extrusion damper by utilizing the energy consumption mechanism with relative angle displacement; and the damper provided by the invention has the advantages of simple construction, stable performance and good expandability and is convenient to process. The relative angle displacement can be directly utilized to enable the central rotating shaft to rotate, thereby extruding the lead to consume energy; and a rotating gear and a translating rack can be adopted to convert the relative translation displacement into the rotation of the central rotating shaft, thereby extruding the lead to consume the energy.
