Problems solved by technology

[0004] At present, the known viscous fluid damper is a piston rod type in structure, and its length is relatively large. It is limited in volume when installed in a narrow space, and only small dampers with poor damping effect can be used, which may easily lead to failure of the construction site. Shock absorption (vibration) design requirements; the existing viscous fluid dampers have poor anti-torsional vibration performance, and in order to achieve the construction effect, the number of viscous fluid dampers is usually increased, resulting in increased construction costs

Abstract

The invention relates to the design field of dampers, in particular to a rotary type viscous fluid damper, which comprises a cylinder body, a front guide sleeve, a rear guide sleeve, a cavity dividing block, a rotary blade and a rotary shaft, wherein the front guide sleeve and the rear guide sleeve are respectively arranged on front and back ends of the cylinder body so as to form a closed space; the rotary blade, the rotary shaft and the cavity dividing block are simultaneously arranged in the closed space; one end of the rotary shaft penetrates through a central point of the front guide sleeve; the other end of the rotary shaft is movably connected with a central point of the rear guide sleeve; the rotary blade is arranged on the side face of the rotary shaft; the cavity dividing block is simultaneously connected with the front guide sleeve and the rear guide sleeve, and divides the closed space into spaces with equal volume; damping holes are arranged on the rotary blade; and damping medium are filled in the closed space. Through applying the technical scheme, the damping effect is better, and the size is smaller.

Description

technical field [0001] The invention relates to the field of damper design, in particular to a rotary viscous fluid damper. Background technique [0002] Energy dissipation and shock absorption technology is to design some non-load-bearing components of the structure as energy dissipation components, or to set up effective components in certain parts of the structure; when the wind or small earthquake occurs, the structure is in an elastic state, and the energy dissipation components or energy dissipation components It can increase the stiffness of the structure; in rare earthquakes, the energy-dissipating components or energy-dissipating components will generate greater damping and consume seismic energy, thereby reducing the dynamic response of the main structure and avoiding the large plastic deformation of the main structure. destroy. At present, the main energy dissipation components that have been developed at home and abroad include: various types of friction damper...
