Abstract
The utility model discloses a damper assembly of a generator group. One end of a bracket 11 and a base 10 of a generator group are fixedly connected, and the other end of the bracket 11 is connected with a bolt 2 and a draw rod 4. The draw rod 4, a base 6 of a diesel engine, and a damper 9 are penetrated by a fixing bolt 5. The damper 9 is fixed on the base 10 of the generator group. Opposite pulling force and torsional torque are given by that an adjusting nut 1, the bolt 2, and the draw rod 4 generate pulling force and torsional torque when the diesel engine is started to run, and thereby, the torsional torque and the pulling force are overcome to ensure the favorable running of the generator group and to achieve the requirements of electric performance.
Description
The utility model relates to a kind of damping device that is used for generating set.
Domestic a large amount of one-cylinder diesel generating set that uses mostly is the small power generator group in the 1-12 kilowatt of scope.Because diesel engine drives generator with V belt when work, V belt has a pulling force and torsional moment to diesel engine simultaneously.Because diesel engine vibrations are very big, cause the whole generating unit that very big bang is also arranged, its four angles must be eliminated or weaken vibrations with Rubber shock-absorbing pad, are beneficial to the even running of generating set.But the elasticity of these beams can make the tension force of V belt change, diesel engine is twisted, motor belt race and V belt and diesel engine pulley groove are not point-blank, reduced transmission efficiency, generator speed is changed, influence the operate as normal of generator.
Task of the present utility model is exactly for overcoming the deficiency of above-mentioned background technology, and provides a kind of simple in structure, can prevent that generator and diesel engine from twisting and the vibration damper assembly of good damping effect.
The technical solution of finishing above-mentioned task is such: be on the support of L type and have a bolt that is connected with pull bar, set bolt is connected pull bar, diesel engine base and reinforcing bar posture rubber absorbers successively, and vibration absorber is fixed on the generating set base.One end of bolt is connected with pull bar by bearing pin, and the other end is fixed on the support by adjusting nut.Have steel skeleton and swivel nut in the rubber layer of vibration absorber, this vibration absorber is by being bolted on the generating set base.Frame bottom is provided with gusset, and this gusset also is connected with the generating set base.
Fig. 1: overall structure schematic diagram of the present utility model.
The vertical view of Fig. 2: Fig. 1.
As shown in Figure 1 and Figure 2, this vibration damper assembly has the support 11 that a vertical section is the L type, and the upper end of support 11 is connected with an adjusting nut 1 and bolt 2, and this bolt 2 is connected with pull bar 4 by bearing pin 3.The swivel nut 14 that set bolt 5 is solidified as a whole with pull bar 4, diesel engine base 6 and with vibration absorber 9 again is fixing successively.The lower end of support 11 and 10 welding of generating set base are fixing, and vibration absorber 9 is fixed on the generating set base 10 by bolt 13, welds a gusset 12 in the bottom of support 11 bottoms and generating set base 10.Described vibration absorber 9 main bodys are rubber layer 8, the swivel nut 14 that in rubber layer 8, has steel skeleton 7 and spin with set bolt 5, and rubber layer 8 bottoms have a female cone platform cavity.
The support 11 of this vibration damper assembly is fixing with 10 welding of generating set base, and set bolt 5 is fastened on pull bar 4 and vibration absorber 9 at the place, diagonal angle of diesel engine base 6.Because of diesel engine will produce a pulling force and torsional moment when starting, and provide an opposite pulling force by the torsional moment of adjusting nut 1, bolt 2 and 4 pairs of diesel engines of pull bar, can reduce or overcome this torsional moment and pulling force, all the time be on the straight line with the belt pulley that guarantees diesel engine and generator, thereby make the startup running of diesel engine main body more steady, guarantee that the generating set operation is normal and reach the electric property requirement.The major function of the rubber layer 8 in the vibration absorber 9 is to absorb the vibrational energy that is transmitted by diesel engine, and the vibrations of diesel engine and base thereof are declined to a great extent.Steel skeleton 7 in the vibration absorber 9 has protection and supports the effect of rubber layer 8; when carrying weight pressure was very big, the distortion of rubber layer 8 was also very big, and steel skeleton 7 just can directly support weight; alleviate the stressed of rubber layer 8, can strengthen the integral rigidity of vibration absorber 9 simultaneously.
The utility model is simple in structure, easy for installation, by regulating pulling force and the torsional moment that produces when bolt can reach reduction or overcome the diesel engine starting running, vibration absorber has good damping performance again, thereby makes the running of whole generating unit and diesel engine more steadily and have a good electric property.
