Abstract
The utility model relates to a silicon oil shock absorber with a belt pulley, particularly to a silicon oil shock absorber with a belt pulley for a diesel motor crankshaft, and belongs to the technical field of shock absorbers. The silicon oil shock absorber with the belt pulley comprises a casing, wherein a ring-shaped cavity is formed in the center of the casing, and a crankshaft through hole allowing an engine crankshaft to be mounted in a sleeving way is formed in the center of the casing; inertia blocks and bearing belts are accommodated in the ring-shaped cavity, the inertia blocks and the casing are separated by the bearing belts in the radial direction, and belt grooves are formed in the outer side surface of the casing. According to the silicon oil shock absorber with the belt pulley, the belt grooves are formed in the outer side of the casing, so that the function of the belt pulley is integrated to the casing of the shock absorber, as a result, the production cost is reduced, and the motor weight is lightened.
Description
Technical field
The utility model relates to a kind of band belt pulley silicon oil damper, and a kind of silicon oil damper with belt pulley of diesel engine bent axle, belongs to vibration damper technical field specifically.
Background technique
At present, vibration damper mainly comprises rubber shock absorber and spring cushion.Silicon oil damper is that damping function is main vibration damper, with self damping absorbing vibrational energy, all produces effect at point of resonance and off-resonance district.Rubber shock absorber is taking frequency modulation as main vibration damper, and main purpose is to change the position of point of resonance in rotating speed district to realize, can only be in specific rotating speed district effectively.The general power of engineering machinery and reverse all greatlyr, work operating mode is severe, as high temperature etc. and rubber element has absorbed too much energy, will soon be aging. and the energy that silicon oil damper absorbs is to have distributed with hot form.And before and after vibration damper, need to install additional belt pulley, drive other auxiliaries, increase weight and the cost of motor.
Model utility content
The purpose of this utility model is to overcome above-mentioned deficiency, thereby a kind of band belt pulley silicon oil damper is provided, and in hull outside, belt grooves is set, and belt pulley function is integrated on the housing of vibration damper, has reduced cost of production.
The technological scheme providing according to the utility model, comprises that with belt pulley silicon oil damper center is provided with the housing of annular cavity, and housing center is provided with the bent axle through hole of suit engine crankshaft.In annular cavity, hold inertial mass and bearing band, bearing band radially separates inertial mass and housing, it is characterized in that: hull outside surface is provided with belt grooves.
Further, belt grooves is profile of tooth.
Further, the opening securing cover plate of annular cavity, cover plate covers annular cavity opening completely.
Further, a radiating fin is welded respectively in the housing left and right sides.
Further, between inertial mass and housing, be provided with position limit cycle.
Compared with the prior art the utility model has the following advantages:
The utility model is simple in structure, compact, reasonable, in hull outside, belt grooves is set, and belt pulley function is integrated on the housing of vibration damper, has reduced cost of production; Alleviate engine weight.
