Abstract
The invention relates to a silicon oil shock absorber, which comprises a shell with an annular cavity and a cover plate fixed at an opening of the cavity; an inertia wheel is fixed in the cavity through a bearing; heat radiating fins are fixed on the surfaces of the cover plate and the shell; and two axial lateral surfaces of the inertia wheel are respectively and fixedly provided with the limit rings which extrude out of respective lateral surface. According to the invention, the heat radiating fins are additionally arranged on the cover plate and the shell, not only the heat radiating capability of the shock absorber is enhanced, the service life of the shock absorber is prolonged, and the decoration effect is achieved; and because the inertia wheel is positioned by the whole limit rings, the silicon oil shock absorber is convenient to install and accurate to position.
Description
Technical field
The present invention relates to vibration damper, specifically a kind of silicone oil vibration damper that is used for the DENG bent axle.
Background technique
Vibration damper mainly comprises spring damper, rubber absorbers and silicone oil vibration damper.The damping effect of spring damper is limited, and spring has been grown the easy deformation inefficacy service time; Rubber absorbers are to be main vibration damper with frequency modulation, and main purpose is to change the position of point of resonance in the rotating speed district to realize, can only be in specific rotating speed district effectively; The silicone oil vibration damper is that damping function is main vibration damper, with self damping absorbed oscillation energy, all produces effect at point of resonance and off-resonance district.
Use the engineering machinery of DENG, general power with reverse all greatlyyer, the operating mode of working is abominable, like high temperature etc.The rubber element of rubber absorbers has absorbed too much energy, will soon wear out; And the energy that the silicone oil vibration damper absorbs is to distribute with the form of heat, therefore is not easy to lose efficacy.
The silicone oil vibration damper generally comprises housing, cover plate, bearing and flying wheel, and flying wheel passes through Bearing Installation in the cavity of housing.But the heat dissipation potential of existing silicone oil vibration damper is not too strong, causes the working life of silicone oil vibration damper shorter; In addition, flying wheel is spacing through limiting stopper, and number of spare parts is many, installs inconvenient.
Summary of the invention
The present invention is directed to the problems referred to above, provide that a kind of heat dissipation potential is strong, the silicone oil vibration damper of long service life.
According to technological scheme of the present invention: a kind of silicone oil vibration damper, comprise the housing that has annular cavity and be fixed on the cover plate of said cavity opening through bearing fixing flying wheel is arranged in the said cavity, be fixed with radiating fin on the surface of said cover plate and said housing.
Said radiating fin comprises the heat radiation bar of annular, and circular array is shown a plurality of radiating fins on the side of said heat radiation bar.
The normal direction axis of said radiating fin and said heat radiation bar an angle radially arranged.
Said radiating fin is divided into long and short two kind specification, is spaced.
Be fixed with the outstanding position limit cycle of side separately on the axial bi-side of said flying wheel respectively.
Technique effect of the present invention is: the present invention has increased radiating fin on cover plate and housing, both strengthened vibration damper heat dissipation potential, prolonged working life of vibration damper, decorative effect is arranged again; Flying wheel is through whole position limit cycle location, and is easy for installation, accurate positioning.
Description of drawings
Fig. 1 is a structural representation of the present invention, is the A-A sectional view among Fig. 2.
Fig. 2 is the left view of Fig. 1.
Embodiment
Be further described below in conjunction with the accompanying drawing specific embodiments of the invention.
Among Fig. 1, Fig. 2, comprise housing 1, bearing 2, flying wheel 3, position limit cycle 4, radiating fin 5, cover plate 6, heat radiation bar 7, radiating fin 8 etc.
Like Fig. 1, shown in Figure 2, the present invention is a kind of toothed silicone oil vibration damper, comprises housing 1 that has annular cavity and the cover plate 6 that is fixed on the cavity opening.Housing 1 center is the through hole that is inserted in engine crankshaft.Be fixed with flying wheel 3 through bearing 2 in the cavity, bearing 4 is to avoid flying wheel 3 and housing 1 direct friction.Be fixed with the outstanding whole position limit cycle 4 of side separately on the axial bi-side of flying wheel 3 respectively, have the gap between position limit cycle 4 and cover plate 6 or the housing 1.Inject silicone oil in the gap between flying wheel 3 and housing 1.
Be fixed with radiating fin 5 on the surface of cover plate 6 of the present invention and housing 1.
Radiating fin 5 comprises the heat radiation bar 7 of annular, and heat radiation bar 7 is welded on cover plate 6 or the housing 1, and circular array is shown a plurality of radiating fins 8 on the side of heat radiation bar 7.
The normal direction axis of radiating fin 8 radially has an angle with heat radiation bar 7, can strengthen radiating effect.
Radiating fin 8 is divided into long and short two kind specification, is spaced.
The present invention has increased radiating fin 5 on cover plate 6 and housing 1, both strengthened vibration damper heat dissipation potential, prolonged working life of vibration damper, decorative effect is arranged again; Change a plurality of limiting stoppers into whole position limit cycle 4, easy for installation, make flying wheel 3 in housing 1, can locate exactly, and can reduce engine weight, reduce number of spare parts, reduce the production management cost.
