Abstract
The utility model discloses an engine silicon oil damper radiation fin, comprising an annular radiation fin body, wherein a plurality of fins are uniformly distributed on one surface of the radiation fin body along a same direction, the included angle between each fin and the radiation fin body ranges from 30 degrees to 60 degrees, radiation holes are arranged between the adjacent fins on the radiation fin body, and radial auxiliary radiation fins are arranged on the edge of the radiation fin body. The engine silicon oil damper radiation fin has a reasonable structure and a good heat radiation effect, and cannot influence the damping effect and the service life of the damper.
Description
Technical field
The utility model relates to a kind of motor silicon oil damper, particularly a kind of motor silicon oil damper radiating fin.
Background technique
Since people invented be used to reduce the torshional vibration damper of engine crankshaft twist vibration amplitude after, greatly reduce the energy loss of motor, the working life of also having improved engine crankshaft simultaneously.Present employed torshional vibration damper is mainly by rubber shock absorber and silicon oil damper two big classes; And for the bigger motor of output power; Then mainly use silicon oil damper; The main structure of silicon oil damper comprises a housing and the flying wheel that is seated in the housing, is marked with silicone oil in the gap between flying wheel and the housing inner chamber.The vibration damper of this structure can reduce the torsional vibration that bent axle is born effectively when engine running.But in long-term using process, it is found that when vibration damper is worked; Because the running of high load can make the temperature fast rise of silicone oil between flying wheel and the housing; When reaching certain temperature, will make silicone oil zoom even carbonization; Lose damping function, thereby the damping effect of vibration damper is disappeared, when serious crankshaft breakdown is had an accident.Existing motor silicon oil damper generally is not with radiating fin, causes the effectiveness in vibration suppression of vibration damper to reduce, and is partly with the vibration damper of radiating fin, because that its radiating fin is provided with is unreasonable, radiating effect is poor, influences the effectiveness in vibration suppression and the working life of vibration damper equally.
The model utility content
It is a kind of rational in infrastructure that the purpose of the utility model just is to provide, and good heat dissipation effect can not influence the motor silicon oil damper radiating fin in vibration damper effectiveness in vibration suppression and working life.
To achieve these goals; The technological scheme that the utility model adopts is such: the motor silicon oil damper radiating fin of the utility model, comprise annular heat sink body, and said heat sink body one surface is provided with several fins; Fin evenly distributes and the direction unanimity; Angle between fin and the heat sink body is 30 degree-60 degree, is provided with radiation hole between two fins on the heat sink body, and the heat sink body edge is provided with auxiliary heat dissipation sheet radially.
As preferably, said fin is a circular arc.
As preferably, the height of said auxiliary heat dissipation sheet is 3-5mm.
Compared with prior art, the advantage of the utility model is: be provided with fin and radiation hole, good heat dissipation effect; Improve the damping effect and the working life of vibration damper, be provided with the auxiliary heat dissipation sheet, increased the heat exchange area of radiating fin; Radiating effect is better, satisfies the heat radiation requirement of vibration damper to greatest extent, makes the temperature of silicone oil be no more than the upper limit of its serviceability temperature; Avoid silicone oil zoom even carbonization, thus the normal use of better more effective assurance motor.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
To combine accompanying drawing that the utility model is described further below.
Referring to Fig. 1, the motor silicon oil damper radiating fin of the utility model comprises annular heat sink body; Said heat sink body one surface is provided with several fins, and fin evenly distributes and the direction unanimity, and the angle between fin and the heat sink body is 30 degree-60 degree; Be provided with radiation hole between two fins on the heat sink body; The heat sink body edge is provided with auxiliary heat dissipation sheet radially, and said fin is a circular arc, and the height of said auxiliary heat dissipation sheet is 3-5mm.
Heat sink body is provided with fin and radiation hole, good heat dissipation effect, the damping effect and the working life of having improved vibration damper; Be provided with the auxiliary heat dissipation sheet, increased the heat exchange area of radiating fin, radiating effect is better; Satisfy the heat radiation requirement of vibration damper to greatest extent; Make the temperature of silicone oil be no more than the upper limit of its serviceability temperature, avoid silicone oil zoom even carbonization, thus the normal use of better more effective assurance motor.
