Abstract

The utility model discloses a damping and shock absorption device for a small aero-engine. The damping and shock absorption device comprises an upper gasket and a lower gasket. A first annular buffer gasket and a second annular buffer gasket are arranged between the upper gasket and the lower gasket from bottom to top, the upper end face and the lower end face of the first annular buffer gasket are respectively provided with a plurality of protruding ridges, a plurality of protruding ridges are arranged on the upper end face of the second annular buffer gasket, and a fixing bolt penetrates through the upper gasket, the second annular buffer gasket, the first annular buffer gasket and the lower gasket. An annular boss is arranged in the middle of the lower end face of the second annular buffer gasket, a plurality of protruding ridges are arranged on the peripheral face of the annular boss at intervals, and the annular boss on the lower end face of the second annular buffer gasket is arranged in a through hole in the middle of the first annular buffer gasket in a sleeved mode. A metal sleeve is arranged in a middle through hole of the second annular buffer gasket in a sleeved mode, and the fixing bolt penetrates through the metal sleeve. The damping and shock absorption device is large in deformation amount, good in shock absorption and buffer effect and capable of protecting the small aero-engine well and lowering noise.

Description

The damping device that a kind of small aero is used

Technical field

The utility model relates to damping device, especially a kind of damping device that is applied to small aero.

Background technique

On motor and other running gear, often to use damping device, to protect motor and running gear, reduce running noise, reduce the mutual impact between component.

Within on 07 25th, 2012, disclosing a patent No. is that ZL201120389654.X, name are called the utility model patent of " beam ", it is a kind of beam between helical spring and axle box that is installed in being applied on engine truck, it comprises that Liang Pian center has the pad of mounting hole, between two pads, in conjunction with being fixed with rubber layer, the center of rubber layer also has mounting hole.This beam by between two pads in conjunction with fixing rubber layer, utilize rubber layer elasticity and damping, effectively reduce high-frequency percussion load and pass to locomotive bogie frame from axle box, the working life of raising engine truck associated components; Although this beam structure is comparatively simple, its amount of deformation is limited, and damping, buffering effect is desirable not enough.

Model utility content

The technical problems to be solved in the utility model is to provide the damping device that a kind of small aero is used, and deformable amount is larger, and damping, buffering is effective, can better protect small aero and reduce noise.

For achieving the above object, the technical solution of the utility model is: the damping device that a kind of small aero is used, comprise Upper gasket, lower levelling plate, the first annular cushion pad, the second loop buffer pad are housed between Upper gasket and lower levelling plate from bottom to top, the upper and lower end face of the first annular cushion pad is equipped with a plurality of fins, the upper-end surface of the second loop buffer pad is provided with a plurality of fins, and a fixing bolt is through Upper gasket, the second loop buffer pad, the first annular cushion pad and lower levelling plate.

Further improve, in the middle of the lower end surface of the second loop buffer pad, be provided with annular boss, the outer circumferential face of described annular boss is interval with a plurality of fins, and the annular boss of the second loop buffer pad lower end surface is enclosed within on the through hole in the middle of the first annular cushion pad.Can better prevent that the first annular cushion pad and the second loop buffer pad from rotating mutually.

Further improve, reinforcement pad is also housed between described fixing bolt and Upper gasket.Strengthen constant intensity.

Preferably described the first annular cushion pad and the second loop buffer pad consist of rubber.

Further improve, in the intermediate throughholes of described the second loop buffer pad, cover has metal sleeve, and metal sleeve is through on fixing bolt.Prevent fixing bolt and the first annular cushion pad and the second loop buffer pad phase mutual friction, the working life of improving the first annular cushion pad and the second loop buffer pad.

The utility model is due to the first annular cushion pad, the second loop buffer pad being housed from bottom to top between Upper gasket and lower levelling plate, the upper and lower end face of the first annular cushion pad is equipped with a plurality of fins, the upper-end surface of the second loop buffer pad is provided with a plurality of fins, by the space forming between fin and fin, larger amount of deformation is provided just to the first annular cushion pad and the second loop buffer pad like this, damping, buffering is effective; Each fin can prevent that again each part from rotating mutually simultaneously, can better protect small aero and reduce noise.

Fig. 2 is the utility model three-dimensional exploded view.

Embodiment

Below in conjunction with accompanying drawing and concrete mode of execution, the utility model is described in further detail.

Shown in Fig. 1, Fig. 2, the damping device that a kind of small aero is used, comprise Upper gasket 1, lower levelling plate 2, the first annular cushion pad 3, the second loop buffer pad 4 are housed from bottom to top between Upper gasket 1 and lower levelling plate 2, the upper and lower end face of described the first annular cushion pad 3 is equipped with a plurality of fins 31, the upper-end surface of described the second loop buffer pad 4 is provided with 41, fixing bolts of a plurality of fins 5 through Upper gasket 2, the annular cushion pad 3 of the second loop buffer pad 4, first and lower levelling plate 1.

In the middle of the lower end surface of the second loop buffer pad 4, be provided with annular boss 42, the annular boss 42 that the outer circumferential face of described annular boss 42 is interval with a plurality of fins 421, the second loop buffer pad 4 lower end surfaces is enclosed within on the middle through hole of the first annular cushion pad 3.

Between fixing bolt 5 and Upper gasket 2, be also equipped with and strengthen pad 6.

Preferably described the first annular cushion pad 3 and the second loop buffer pad 4 are made by rubber material.

In the intermediate throughholes of the second loop buffer pad 4, cover has metal sleeve 7, and metal sleeve 7 is through on fixing bolt 5.

Below be only preferred embodiment of the utility model, the change that those skilled in the art does to be equal to by claim all falls into the protection domain of this case.
