Abstract

The utility model discloses a radiating fin for a silicon oil damper of an engine, comprising a disc radiating fin body; strip-shaped radiating bumps are uniformly distributed in the peripheral direction of the radiating fin body; the strip-shaped radiating bumps are helically distributed on the radiating fin body; an air flow path allowing the air to flow along the radiating fin body radially is formed between every two adjacent strip-shaped radiating bumps; the tops of the strip-shaped radiating bumps are provided with radiating gaps; during the rotation process of the damper, the strip-shaped radiating bumps provide dynamic energy to the air for passing through the air flow path, so that the air flows along the radial direction of the damper and takes away the heat from the radiating fin, and the heat exchange efficiency is improved greatly; the strip-shaped radiating bumps have large rigidity, stable structure, and stable operation without noise generated even the rotating speed is very high. Therefore, the silicon oil damper of the engine keeps good shake absorption all the time, the service life of the silicon oil damper of the engine is prolonged, and the normal operation of the engine is ensured.

Description

Motor silicon oil damper radiating fin

Technical field

The utility model relates to a kind of motor silicon oil damper heat-dissipating part.

Background technique

As Fig. 4, Fig. 5, Fig. 6 and shown in Figure 7, the silicone oil torshional vibration damper absorbs vibrational energy by the inertia of inertia ring 6 and the damping of silicone oil, reduces the torsional oscillation of axle system.The heat energy that interact to produce between inertia ring 6 and the silicone oil sheds to the external world by the radiating fin 4 that is arranged on the vibration damper.Radiating fin 4 is provided with heat radiation wing plate 5, and heat radiation wing plate 5 only can make radiating fin 4 ambient airs along the disturbance of vibration damper circumferencial direction, and the hot air flow of disturbance can't flow, and greatly reduces heat exchange efficiency.And heat radiation wing plate 5 rigidity are relatively poor, and vibration is uttered long and high-pitched sounds under the rotating speed condition with higher easily easily, produces noise pollution.Therefore, lower heat dissipation potential causes that easily the damping constant between silicone oil and the inertia ring 6 changes, and has reduced effectiveness in vibration suppression, has shortened working life, even the damping effect inefficacy takes place, and causes major accidents such as crankshaft breakdown.

The model utility content

Technical problem to be solved in the utility model provides a kind of rapid heat dissipation, motor silicon oil damper radiating fin that noise is little.

For solving the problems of the technologies described above, the technical solution of the utility model is: motor silicon oil damper radiating fin, be fixedly mounted on motor silicon oil damper both ends of the surface, comprise discoid radiating fin lamellar body, the circumferentially uniform bar shaped heat radiation projection that is provided with of described radiating fin lamellar body, the described bar shaped protruding helical of dispelling the heat is arranged on the described radiating fin lamellar body, form between the described adjacent bar shaped heat radiation projection and make the air flow channel of air along described radiating fin lamellar body Radial Flow, described bar shaped heat radiation convex top is provided with the heat radiation seam.

As optimized technical scheme, described bar shaped heat radiation projection is arc heat radiation projection.

As optimized technical scheme, described arc heat radiation projection is an arc-shaped convex.

Owing to adopted technique scheme, motor silicon oil damper radiating fin, be fixedly mounted on motor silicon oil damper both ends of the surface, comprise discoid radiating fin lamellar body, the circumferentially uniform bar shaped heat radiation projection that is provided with of described radiating fin lamellar body, the described bar shaped protruding helical of dispelling the heat is arranged on the described radiating fin lamellar body, forms between the described adjacent bar shaped heat radiation projection and makes the air flow channel of air along described radiating fin lamellar body Radial Flow, and described bar shaped heat radiation convex top is provided with the heat radiation seam; In the vibration damper rotation process, described bar shaped heat radiation projection gives air with the kinetic energy by air flow channel, makes air along the vibration damper Radial Flow, and the heat on the radiating fin is taken away, and has improved heat exchange efficiency greatly; And the described bar shaped protruding rigidity of dispelling the heat is big, structural stability, even also can not produce noise under the rotating speed condition with higher, it is more steady to turn round.Therefore, the effectiveness in vibration suppression that the motor silicon oil damper is remained has prolonged working life of motor silicon oil damper, guarantees the normal operation of motor.
