Description
Technical field
The utility model is related to a kind of generator assembly, more particularly to a kind of generator noise abatement antishock device.
Background technology
Generator（English name：Generators）Be by the energy conversion of other forms into electric energy plant equipment, it
Driven by the hydraulic turbine, steam turbine, diesel engine or other dynamic power machines, current, air-flow, fuel combustion or nuclear fission are produced
Energy be converted into mechanical energy and be transmitted to generator, then electric energy is converted to by generator.Generator is in industrial and agricultural production, national defence, section
Have been widely used in skill and daily life.
The form of generator is a lot, but its operation principle is all based on the law of electromagnetic induction and law of electromagnetic force.Therefore, its structure
The rule made is：The magnetic circuit and circuit for carrying out electromagnetic induction mutually are constituted with appropriate magnetic conduction and conductive material, to produce
Electromagnetic power, reaches the purpose of energy conversion.
Generator can supplement electric power in time when having a power failure, and the production and living order of people is obtained effectively
Ensure.But the noise of generator is one of technological deficiency of generating set, as long as generator one starts, its noise level can be with
Up to 80 to 100 decibels, the noise can produce body and psychological infringement to the people on periphery.The noise of generator is mainly
What the internal noise of mechanical shock and machinery was constituted, so the noise of reduction generator should be from the vibrations of generator and interior
The mechanicalness noise in portion is started with.
Utility model content
The purpose of this utility model is to provide a kind of simple in construction, and production assembling is easy, and sound insulation damping effect is significantly sent out
Motor noise abatement antishock device.
To achieve the above object, the technical scheme that the utility model is used is：A kind of generator noise abatement antishock device, bag
Include：Generator main body, the generator main body is made up of main shaft and shell, it is characterised in that：Described shell by front shell cover, after
Cap and middle casing are constituted, and are equipped with rotary sleeve on described front shell cover and rear shell cover, main shaft passes through the rotary sleeve
It is fixedly mounted in shell；Between described front shell cover and middle casing be provided with cushion blocking, described front shell cover, rear shell cover with
And damping sound-absorbing part is equipped with middle casing.
Preferably, described front shell cover center portion is hollow structure, and damping sound-absorbing material is filled with the hollow structure,
The damping sound-absorbing material is brought into close contact by irrigating to install with front shell cover.
Preferably, described middle casing center portion is hollow structure, and damping sound absorber is filled with the hollow structure
Material, the damping sound-absorbing material is brought into close contact by irrigating to install with middle casing.
Preferably, described rear shell cover center portion is hollow structure, and damping sound-absorbing material is filled with the hollow structure,
The damping sound-absorbing material is brought into close contact by irrigating to install with rear shell cover.
Preferably, described damping sound-absorbing material is polyurethane.
Preferably, it is additionally provided with blimp on the main shaft link position of described front shell cover and rear shell cover.
Preferably, described rotary sleeve is self-aligning ball bearing.
Beneficial effect
The utility model is by using in generator inner casing sound insulation by filling vibration-absorptive material, while being respectively provided with the two ends of rotating shaft
There is blimp, the noise and vibrations for making generator are obstructed and absorbed by generator housing, the rotation connection of rotating shaft
The noise at place is obstructed by blimp to be absorbed so that the level that the overall noise of generator is preferably minimized, it is achieved thereby that generator
Noise abatement antidetonation purpose.The utility model is simple in construction, and production assembling is easy, and sound insulation damping effect is obvious.
