Embodiment Construction

[0043] The present invention will be further described below in conjunction with the accompanying drawings.

[0044] The invention proposes a leak-free rotating and axial fluid damper, which uses magnetic force to push the blades in the damper to rotate and the piston to move. When the blades rotate (pistons move), the damping fluid flows through the small holes on the blades (pistons). Round through hole (damping hole), when the damping fluid flows through the small round hole (damping hole) on the vane (piston), it consumes energy, which has the effect of controlling vibration.

[0045] The following descriptions of embodiments of the invention are merely exemplary in nature, and are in no way intended to limit the application or uses of the invention.

[0046] This leak-free rotation and the spring of the shaft-moving fluid damper are taken as circular springs, and the fourth permanent magnet piece 30 is taken as an example of the fourth columnar permanent magnet piece 30 a...

Abstract

The invention relates to a no-leakage rotatable and axially movable fluid damper, which comprises a first disc (1), a bottom disc flange (19), a hydraulic cylinder (17), a cylinder (35), a stepped cylinder (11), a second circular shaft (78), a thrust bearing (79) and a second disc (82), wherein the bottom disc flange (19) is arranged oppositely to the first disc (1), the first disc (1) and the bottom disc flange (19) are connected by the hydraulic cylinder (17) in no-leakage manner, the cylinder (35) is provided with a disc flange at the upper and an opening. An upper disc flange (47) is arranged at the upper end of the cylinder (35) with a disc flange at the upper end, and a concave groove (80) is arranged on the upper portion of the stepped cylinder (11). By the aid of magnetic force, blades in the damper are driven to rotate and the pistons in the dumper are driven to axially move. When the blades rotate and the pistons move axially, the damping fluid is led to flow through small round through holes on the blades and the pistons to consume energy, so that the rotation around the axes of the pistons and the vibrations along the axes of the pistons can be controlled. Without sealing member, the damping fluid is not easy to leak from the damper.

Description

technical field [0001] The invention proposes a "no-leakage rotational and axial fluid damper", which belongs to the field of structural vibration control. Background technique [0002] The fluid damper is an effective structural damper, but during the working process of the fluid damper, there is a possibility of fluid leakage in the fluid damper. limit. The present invention proposes a fluid damper, the damper does not use seals, so it is not prone to liquid leakage faults, and the damper can simultaneously control the linear displacement vibration along the axis of the hydraulic cylinder of the damper and the vibration of rotational displacement around the axis of the hydraulic cylinder . Contents of the invention [0003] technical problem: The purpose of the present invention is to propose a "no-leakage rotary and axial fluid damper", which is especially suitable for structural vibration control under the condition that no leakage is allowed. [0004] Technical ...
