Abstract
The utility model discloses a heat radiating device of a silicone oil tortional vibration damper of an engine, which comprises radiating fins arranged on the outer end face of a vibration damper shell and is characterized in that the excircle surface of the vibration damper shell is provided with radially-protruding auxiliary radiating fins; and the auxiliary radiating fins are circular fins which surrounds the excircle surface of the vibration damper shell and are uniformly distributed along the axial direction. The heat radiating device has the advantages that the heat radiating effect of the heat radiating device is further improved, the heat radiating requirement of the vibration damper is met to the maximum extent, the temperature of the silicone coil is maintained below proper temperature, the silicone oil is prevented from being burnt or even carbonized, thereby effectively ensuring the normal safe use of the engine.
Description
Technical field
The utility model relates to a kind of engine snubber, especially relates to a kind of sink of motor silicone oil torshional vibration damper.
Background technique
Since people have invented after the engine crankshaft front end installs torshional vibration damper additional, not only avoided taking place because of the incident that strong torsional oscillation bent axle is twisted off, also significantly reduced simultaneously impact and noise in the running of axle system, greatly improved reliability, the working life of motor and improved working environment.The torshional vibration damper that uses mainly contains rubber shock absorber and the silicon oil damper two big classes that are applicable to high power engine at present.Silicon oil damper be one by the seal casinghousing that is fixed in crankshaft free-end and be assigned in flying wheel in the housing, the device with viscous silicone fluid is filled in the crack between flying wheel and housing.When silicone oil plays attenuation to torsional vibration, because of the friction between self molecule is generated heat, if the heat radiation of housing fails to stop the silicone oil temperature to rise, but reach so that above prescribing a time limit on its operating temperature, damping effect will obviously descend, even silicone oil meeting zoom and carbonization, vibration damper function total failure.For guaranteeing the normal safe handling of motor, No. 200920198123.5 Chinese utility model patents as the inventor is application on October 12nd, 2009 satisfy the requirement of dispelling the heat by corresponding radiating fin is set on the exterior edge face of housing.But, only be arranged on the requirement that two radiating fin on the end face can not satisfy heat radiation when engine power configuration space bigger, vibration damper has again in limited time.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of heat radiation requirement that can satisfy silicon oil damper to greatest extent, effectively reduces the sink of the motor silicone oil torshional vibration damper of vibration damper operating temperature.
The utility model solves the problems of the technologies described above the technological scheme that is adopted: a kind of sink of motor silicone oil torshional vibration damper, comprise the radiating fin that is arranged on the shock absorber casing exterior edge face, the outer round surface of described shock absorber casing is provided with the auxiliary heat dissipation sheet of radial protrusion, and described auxiliary heat dissipation sheet is the circular ring plate of outer round surface around described shock absorber casing evenly arranged along the axial.
The height of described auxiliary heat dissipation sheet is: 3 ~ 5mm, the thickness of described auxiliary heat dissipation sheet is: 2 ~ 3mm, the spacing between the adjacent described auxiliary heat dissipation sheet is 2.5 ~ 5 mm.
Described auxiliary heat dissipation sheet is wholely set on described shock absorber casing.
Compared with prior art, advantage of the present utility model is that the outer round surface by shock absorber casing is provided with the auxiliary heat dissipation ring plate of radial protrusion, further improve the radiating effect of sink, satisfy the heat radiation requirement of vibration damper to greatest extent, the temperature of silicone oil is remained under the suitable temperature, avoid silicone oil zoom even carbonization, thus the normal safe handling of better more effective assurance motor.
