Abstract

Provided is a rotating and shaft-driving fluid damper. The rotating and shaft-driving fluid damper comprises an upper part and a lower part, wherein the upper part and the lower part are independent from each other. The upper part of the rotating and shaft-driving fluid damper comprises an upper disc flange (1), a first permanent magnet block (14), a first pressing block (13), a third permanent magnet block (6) and a third pressing block (7). The first permanent magnet block (14) is fixed inside the upper-portion disc flange (1) through the first pressing block (13), and the third permanent magnet block (6) is fixed inside the upper disc flange (1) through the third pressing block (7). The active line of resultant force of received magnetic force of the third permanent magnet block (6) coincides with the axis of a circular shaft (39). When a vibrating body vibrates, rotating blades inside the damper are driven to rotate by the magnetic force, and a piston inside the damper is driven to move by the magnetic force and a spring. When the rotating blades rotate and the piston moves, damping fluid flows through small round through holes in the rotating blades and the piston, and energy is consumed when the damping fluid flows through the small round through holes in the rotating blades and the piston.
