Abstract

The utility model discloses a radiating fin of an engine silicone oil torsion shock absorber, comprising a ring-shaped substrate which is provided with an axial hole at the central position, a plurality of short blades and a plurality of long blades, which are formed by punching and are protruded to the surface of the ring-shaped substrate, are arranged on the ring-shaped substrate in an integrating way, the short blades and the long blades are uniformly arrayed at interval along the circumferential direction, an included angle formed by the extension line of the long side of the short blade and the extension line of the long side of the long blade and the radial coordinate line of the ring-shaped substrate which takes a circle center as an original point, is 0-15 degrees, the included angle of the short blade and the long blade and the plane of the ring-shaped substrate are equal, that is, 90-120 degrees; the radiating fin has the advantages that heat on the shell can be taken away by the ring-shaped substrate along with the rotation of the shell of the shock absorber, so as to lead the temperature of the silicone oil to be kept in proper temperature, avoid silicone oil coking even carbonation and effectively ensure the normal safety usage of the engine.

Description

A kind of radiating fin of motor silicone oil torsional vibration damper

Technical field

The utility model relates to a kind of engine snubber, especially relates to a kind of radiating fin of motor silicone oil torshional vibration damper.

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 mainly contains rubber shock absorber and silicon oil damper two big classes.And, then mainly use silicon oil damper for the bigger motor of output power.The main structure of silicon oil damper comprises a housing and is seated in the interior flying wheel of 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 of silicone oil raise fast 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.For this reason, people imagination is provided with various sinks at the outer surface of the housing of vibration damper and helps the temperature of vibration damper when reducing work, thus the normal safe handling of better more effective assurance motor.

Summary of the invention

Technical problem to be solved in the utility model provides on a kind of any exterior edge face that can be arranged on motor silicone oil torshional vibration damper housing easily and can effectively reduce the radiating fin of this vibration damper operating temperature.

The utility model solves the problems of the technologies described above the technological scheme that is adopted: a kind of radiating fin of motor silicone oil torshional vibration damper, comprise an annular substrate that is provided with axis hole in the center portion, be wholely set stamping forming a plurality of short blades and a plurality of linear leaf that protrudes from the surface of described annular substrate on the described annular substrate, described short blade and described linear leaf evenly are spaced along circumference, the elongation line on the elongation line on the long limit of described short blade and the long limit of described linear leaf and annular substrate are that the angle that the radial coordinate line of initial point is become is with the center of circle: 0 °～15 °, described short blade and described linear leaf equate to be with angle between the described circular base plate plane: 90 °～120 °.

Described short blade and described linear leaf height are: 3～5cm, the thickness of described annular substrate is: 0.5～1.5cm.

Described short blade equal in length, the equal in length of described linear leaf.

Compared with prior art, advantage of the present utility model is and can takes away heat on the housing with the rotation of shock absorber casing by annular substrate, 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.
