Abstract
An objective of the utility model is to provide a low-noise diesel generator which reduces vibration of the diesel generator. The low-noise diesel generator comprises a diesel engine and a generator fixed on a base, and the key point is that the diesel engine also comprises a reduction gear. An engine shaft of the diesel engine is connected with a driving shaft of the reduction gear through an elastic coupler. A shaft of the generator is connected with a driven shaft of the reduction gear through the elastic coupler. The reduction gear can transform high-speed rotation of the diesel engine into low-speed rotation of the generator, and make rotation of the diesel engine and the generator asynchronous, thereby preventing resonance of the diesel engine and the generator, reducing total amplitude of the diesel engine and the generator, and realizing an objective of silencing. In addition, since the engine shaft of the diesel engine and the shaft of the generator are respectively connected with the reduction gear through the elastic coupler, and the elastic coupler can eliminate most vibration, so that noise is further reduced.
Description
Technical field
The utility model belongs to the diesel engine generator technical field, specially refers to a kind of low noise diesel engine generator.
Background technology
Diesel engine generator generally is comprised of diesel engine and generator, and wherein the arbor of the arbor of diesel engine and generator is fixedly connected with, and rotates thereby utilize diesel engine to drive generator, realizes generating.Diesel engine and generator all can produce vibration when work, and both vibrations are synchronous, cause the vibration of diesel engine generator integral body very severe, workmen around not only can affecting, cause other people to work, and the vibration also can cause the precision elements such as instrument of diesel engine generator self to suffer damage, affect useful life.
The utility model content
The purpose of this utility model is to propose a kind of low noise diesel engine generator, to reduce the vibration of diesel engine generator.
Low noise diesel engine generator of the present utility model comprises diesel engine and the generator that is fixed on the base, and key is that this diesel engine generator also comprises a reductor; The arbor of described diesel engine is connected with the driving shaft of described reductor by spring coupling, and the arbor of described generator is connected with the driven shaft of described reductor by spring coupling.
Reductor can be converted into the high speed rotating of diesel engine slowly running of generator, so that both rotations are no longer synchronous, can prevent that like this diesel engine and generator from resonating, and has reduced the whole amplitude of diesel engine generator, has realized the purpose of noise elimination.In addition, be to be connected with reductor by spring coupling respectively because the arbor of diesel engine is connected arbor with generator, spring coupling can be eliminated most vibration, has further reduced noise.
Further, described diesel engine and generator all by spring supporting on base.When diesel engine generator was worked, the vibration meeting that diesel engine and generator produce was transmitted on the base by spring, and was absorbed by spring and suppress, and so just can reduce vibration.
Diesel engine generator of the present utility model so that the body vibration of diesel engine generator can access good inhibition, has good practicality by spring coupling and reductor are set.
Description of drawings
Fig. 1 is the structural representation of low noise diesel engine generator of the present utility model.
Embodiment
The below contrasts accompanying drawing, by the description to embodiment, the effect of the mutual alignment between the shape of embodiment of the present utility model such as related each member, structure, the each several part and annexation, each several part and operation principle etc. are described in further detail.
Embodiment 1:
As shown in Figure 1, 2, the low noise diesel engine generator of present embodiment comprises diesel engine 2 and the generator 3 that is fixed on the base 1, and this diesel engine generator also comprises a reductor 4; The arbor of diesel engine 2 is connected with the driving shaft of reductor 4 by spring coupling 5, and the arbor of generator 3 is connected with the driven shaft of reductor 4 by spring coupling 6.
Reductor 4 can be converted into the high speed rotating of diesel engine 2 slowly running of generator 3, so that both rotations are no longer synchronous, can prevent that like this diesel engine 2 and generator 3 from resonating, and has reduced the whole amplitude of diesel engine generator, has realized the purpose of noise elimination.In addition, because the arbor that the arbor of diesel engine 2 is connected with generator is to be connected with reductor 4 by spring coupling 5,6 respectively, spring coupling 5,6 can be eliminated most vibration, has further reduced noise.
