Abstract
The utility model provides a silicon oil damper, which is composed of an inertia ring, silicon oil, a cover plate, a housing, a bearing and a plug arranged on the housing, wherein annular cooling fins are welded on two end faces of the housing of the silicon oil damper. By arranging the cooling fins, the silicon oil damper has increased heat dissipation area and improved heat dissipation capacity, and overcomes the disadvantages resulting from premature failure of silicon oil such as reduced torsional vibration effect and shortened service life.
Description
Technical field
The utility model relates to a kind of silicon oil damper that is applied to motor car engine.
Background technique
Current, the torshional vibration damper that motor car engine is used, silicon oil damper and rubber shock absorber two big series are arranged, traditional silicon oil damper is made up of inertia ring, silicone oil, cover plate, housing, bearing, six kinds of parts of obstruction, housing and cover plate link together with the mode of electron beam welding, inertia ring places housing and cover plate inside, fills silicone oil all around.In use, housing is connected with bent axle.When engine rotation, housing, bent axle and the inertia ring that is suspended in the housing inner chamber are rotated simultaneously.When vibration takes place in axle system, absorb vibrational energy by the inertia of inertia ring and the damping of silicone oil, play damping effect.But have the power of a lot of motors constantly increasing at present, the heat generation when turning round simultaneously increases, and heat dissipating ability is poor, causes the silicone oil premature failure, reduces and shortens in effectiveness in vibration suppression and working life.
Summary of the invention
Poor for the heat dissipating ability that solves existing silicon oil damper, cause the silicone oil premature failure, reduce the problem that effectiveness in vibration suppression and working life shorten, the utility model proposes a kind of silicon oil damper.
For this reason, the technical solution of the utility model is: silicon oil damper, and be installed on the housing and form by inertia ring, silicone oil, cover plate, housing, bearing, six kinds of parts of obstruction, it is characterized in that: the both ends of the surface at the housing of silicon oil damper are welded with annular fin.
Beneficial effect: owing to be provided with radiating fin, increased the heat diffusion area of vibration damper, improved heat dissipating ability, reduced silicone oil because defectives such as torsional oscillation effect reduction that premature failure causes and shortenings in working life in the silicon oil damper both ends of the surface.
Description of drawings
Fig. 1 is a structural front view of the present utility model.
Fig. 2 is a side view of the present utility model.
Embodiment
As shown in Figure 1, 2, it is as follows to describe the utility model: silicon oil damper, and housing 4 links together with the mode of cover plate 3 welding; Inertia ring 1 places housing 4 and the inner chamber that cover plate 3 forms, and fills silicone oil 2 around the inertia ring 1, and the hand-hole of silicone oil is blocked in obstruction 7, is provided with bearing 5 between inertia ring 1 and the housing; Housing 4 both ends of the surface of silicon oil damper are welded with annular fin 6.Described annular fin 6 is drawings.
Claims (2)
1, silicon oil damper is installed on the housing and is formed by inertia ring, silicone oil, cover plate, housing, bearing, six kinds of parts of obstruction, it is characterized in that: the both ends of the surface at the housing of silicon oil damper are welded with annular fin.
2, silicon oil damper according to claim 1 is characterized in that: described annular fin is drawing.
