Abstract

The invention relates to a rotating type viscous fluid damper which comprises an oil cylinder, a front lining, a rear lining, a piston rod, a piston, a damping medium, a sleeve, a pin head and a connecting pipe assembly. A bearing is arranged at the connecting position of the piston and the piston rod in an embedded manner. Multiple clamping grooves are formed in the outer end face of the piston in the direction of the end face of the piston. Blades are fixedly connected in the clamping grooves. The rotating type viscous fluid damper is simple in structure, the blades generate rotating movement under the effect of medium pressure, and therefore the linear movement of the piston rod of the viscous fluid damper is converted into the circular movement, the damping effect of the damper can be well ensured, adjustability of the damping characteristic is achieved, damping medium convection is accelerated at the same time, the radiating efficiency of the damper is improved, and the service life of the product is prolonged.

Description

technical field [0001] The invention relates to the technical field of viscous fluid dampers, in particular to a rotary viscous fluid damper. Background technique [0002] In recent years, viscous fluid dampers have been widely used in the seismic design of buildings and bridge engineering structures. It has the characteristics of flexible layout, small space occupation, can significantly improve the seismic performance of the structure, and has no additional rigidity to the structure. The common viscous damper is a hydraulic cylinder type, and its working mechanism is: the piston reciprocates axially in the oil cylinder, during which the damping medium passes through the damping hole or the damping gap at high speed, converting the mechanical energy generated by the vibration into heat dissipation, so as to realize the structure The purpose of shock absorption (vibration). The damping material in traditional viscous dampers usually adopts high-viscosity damping medium. T...
