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.

Leak interpolation first spring in rotation and the moving fluid damper of axle in above-mentioned nothing, obtain not having the another kind of style of rotation of leaking and the moving fluid damper of axle; Wherein: the upper end of first spring is connected with the piston lower surface, and the lower end of first spring is connected with first circular shaft, and the lower end of first spring is positioned at the top of the upper surface of dividing plate; First spring is to the dead in line of the line of action of making a concerted effort and first circular shaft of the active force of piston.

Leak interpolation second spring in rotation and the moving fluid damper of axle in above-mentioned nothing, obtain not having the another kind of style of rotation of leaking and the moving fluid damper of axle; Wherein: the lower end of second spring is connected with the upper surface of piston, and the upper end of second spring is connected with the top of first circular shaft, and second spring is to the dead in line of the line of action of making a concerted effort and first circular shaft of the active force of piston.

Leak interpolation second spring, first spring in rotation and the moving fluid damper of axle in above-mentioned nothing, obtain not having the another kind of style of rotation of leaking and the moving fluid damper of axle; Wherein: the lower end of second spring is connected with piston upper surface, and the upper end of second spring is connected with the top of first circular shaft; The upper end of first spring is connected with the piston lower surface, and the lower end of first spring is connected with first circular shaft, and the lower end of first spring is positioned at the top of the upper surface of dividing plate; Second spring is to the dead in line of the line of action of making a concerted effort and first circular shaft of the active force of piston; First spring is to the dead in line of the line of action of making a concerted effort and first circular shaft of the active force of piston.

Leak interpolation the 3rd spring in rotation and the moving fluid damper of axle in above-mentioned various forms of nothings, obtain not having the another kind of style of rotation of leaking and the moving fluid damper of axle; The upper end of the 3rd spring is connected the upper end and has on the lower end surface of upper end disc flange of cylinder of disc flange, and the lower end of the 3rd spring is connected on the upper surface of first disk.

During use; The upper end disc flange that the upper end has the cylinder of disc flange is fixed on the oscillating body (or static basis); The upper surface of upper end disc flange that the upper end has the cylinder of disc flange contacts with oscillating body (or static basis); The bottom disc flange is fixed on the static basis (or oscillating body), and the upper end has the distance of upper surface of lower surface and first disk of upper end disc flange of cylinder of disc flange greater than the maximum vibration displacement of oscillating body with respect to the basis; The upper end has the axis of the cylinder of disc flange, the axis of bottom disc flange, the axis of oil hydraulic cylinder, the axis of first disk, the axis of first circular shaft, the axis of piston, the axis of Hollow Cylindrical Shaft, the axis of stepped cylinder, the axis of dividing plate, the axis of second disk, the axis of second spring, the axis of first spring and the dead in line of the 3rd spring.Because first permanent magnetic iron block in the piston has the magnetic attraction effect between the 4th permanent magnetic iron block in the cylinder of disc flange with the upper end; When oscillating body was static, piston was in the static balance state under the acting in conjunction of gravity, magnetic force, second spring and first spring etc., when oscillating body vibrates; Stepped cylinder will be drawn piston and moved along circular shaft; During piston motion, damp liquid flows through the second little round tube hole on the piston, and damp liquid flows through the second roundlet through hole dissipative structure vibrational energy on the piston; Because second permanent magnetic iron block in the rotor blade is with the magnetic attraction effect between the 3rd permanent magnetic iron block in the stepped cylinder, when oscillating body was static, rotor blade was in the static balance state under effects such as magnetic force, and was positioned at the centre of two stator blades; When oscillating body vibrates; Cylinder and stepped cylinder that the upper end has a disc flange will be drawn rotor blade and rotated around first circular shaft; When rotor blade rotates; Damp liquid will flow through the first little round tube hole on the rotor blade, and damp liquid flows through the first roundlet through hole dissipative structure vibrational energy on the rotor blade.

Beneficial effect:Oil hydraulic cylinder, bottom disc flange, disk are formed does not have the confined space of leakage; Blade is rotated around circular shaft in this confined space by Magnetic force tracting on the one hand; When blade rotation; Damp liquid flows through the little round tube hole on the blade, and damp liquid consumes energy when flowing through the roundlet through hole on the blade, plays the effect that suppresses vibration; Magnetic force also can draw piston and in this confined space, moves along circular shaft on the other hand, and when piston motion, damp liquid flows through the small sircle hole on the piston, and damp liquid consumes energy when flowing through the small sircle hole on the piston, plays the effect that suppresses vibration.So when no matter this had only rotational vibrations or have only axial vibration, when perhaps rotational vibrations and axial vibration took place simultaneously, this damper can provide effective vibration control damping.Owing to do not use Sealing, blade and piston only do not move in having the confined space of leakage, and the phenomenon of leakage of general fluid damper in the vibration control process can not appear in this fluid damper.The distance of the distance of first permanent magnetic iron block 4 and the 4th permanent magnetic iron block 30 and second permanent magnetic iron block 14 and the 3rd permanent magnetic iron block 26 can be very near, do not receive the influence of vibration displacement, presses the electromagnetism principle, and magnetic force is bigger, thereby bigger damping force can be provided.And because second circular shaft 78 moves up and down in groove with the cylinder that the upper end has disc flange; Only rotation is passed to stepped cylinder; Make stepped cylinder and the 3rd inner permanent magnetic iron block 26 only do rotation around hydraulic cylinder axis; The 3rd permanent

magnetic iron block

26 and 14 of second permanent magnetic iron blocks do not take place along the change in location of hydraulic cylinder axis direction, can obtain maximum magnetic force.
