Description
Technical field
This utility model relates to a kind of device that can reduce noise, and especially motor silencing means, belongs to electro-mechanical arts.
Background technology
Motor is widely used a kind of plant equipment in industrial and mining establishment.Such as, various water pumps, oil pump, fridge, pressure
Contracting machine, lathe etc. will be equipped with motor.Some motor is on-stream gives off stronger noise, the most even can become whole
The main noise of individual unit, causes sound pollution, noise to directly affect the healthy of people, the strongest or long-time noise, meeting
Make that people is the most painful, feel bad, even make people deaf or dead.Therefore must eliminate or reduce the noise of motor.
The noise of motor is broadly divided into aerodynamic noise, electromagnetic noise, mechanical noise three part.Aerodynamic noise master
If the rotational noise periodically hit surrounding air particle and division air-flow due to cooling fan blade sheet and produce and eddy current crack.
Electromagnetic noise is that the vibration caused due to the electromagnetic attraction between stator and rotor, changes of magnetic field produces.Mechanical noise is main
Owing to motor operation is uneven and bearing friction produces.In these several partial noise, the air force that cooling fan produces
Noise is the strongest, considerably beyond electromagnetic noise and mechanical noise sum of the two.
Piezoelectric is that it can produce potential difference, can this electrical power storage be got up when it is applied pressure.
Piezoelectric has crystal, macromolecule, new ceramics three types.Belong to the vinylidene piezoelectric film of high polymer piezoelectric material
Good stability, high thermal stability, high impact resistance, endurance.
Utility model content
Problem to be solved in the utility model is to provide a kind of motor silencing means that can reclaim electric moter noise energy.
For solve above-mentioned technical problem, the technical solution of the utility model is as follows: motor silencing means, including motor body,
Cooling fan and brush, described cooling fan and brush lay respectively at the two ends of motor, motor body head shell, its feature
Be: also include motor silencing means shell, baffle plate one, vent, piezoelectric part, sound gobo, apertured partition,
Electrical energy storage section, wire and baffle plate two, described motor silencing means shell is rectangle, the brush of close motor body
The most not closed, baffle plate one is installed, the shell of the close brush of described motor body is provided with baffle plate two, baffle plate one He
Baffle plate two is mutually perpendicular to, and there is gap formation vent, has apertured partition, institute between described cooling fan and piezoelectric part
Stating apertured partition and be positioned at motor silencing means shell, described sound gobo is parallel to motor body head shell, described pressure
Electricity parts are installed on described sound gobo and face the one side of cooling fan, and described electrical energy storage section is positioned at motor silencing means
Outside shell, it is connected with piezoelectric part by wire.
The bore dia of apertured partition is 5 10mm, and hole is axially perpendicular to sound gobo.
Piezoelectric part preferred polyunsymfluorethylepiezoelectric piezoelectric film, it is achieved noise and the conversion of electric energy.
This utility model not only can eliminate the noise that motor running produces, the most also by the energy regenerating in noise.

Detailed description of the invention
Below in conjunction with embodiment, the detailed description of the invention of the present invention is further described, the most therefore limits the present invention to institute
Among the scope of embodiments stated.
Embodiment 1
As Fig. 1 motor silencing means is installed shown in profile, motor silencing means includes motor body 1, cooling fan
2 and brush 3, described cooling fan 2 and brush 3 lay respectively at the two ends of motor, motor body head shell 13, and it is special
Levy and be: also include motor silencing means shell 4, baffle plate 1, vent 6, piezoelectric part 7, sound gobo 8,
Apertured partition 9, electrical energy storage section 10, wire 11 and baffle plate 2 12, described motor silencing means shell 4 is rectangle,
Not closed near the one side of the brush 3 of motor body 1, baffle plate 1, the close brush 3 of described motor body 1 are installed
Shell on baffle plate 2 12, baffle plate 1 and baffle plate 2 12 be installed be mutually perpendicular to, and there is gap and form vent 6,
Apertured partition 9, described apertured partition 9 is had to be positioned at outside motor silencing means between described cooling fan 2 and piezoelectric part 7
In shell 4, described sound gobo 8 is parallel to motor body head shell 13, and described piezoelectric part 7 is installed on described noise reduction
Dividing plate 8 faces the one side of cooling fan 2, and described electrical energy storage section 10 is positioned at outside motor silencing means shell 4, logical
Cross wire 11 to be connected with piezoelectric part 7.
Piezoelectric part 7, sound gobo 8 and electrical energy storage section 10 are provided with upper and lower 2 groups.
The aerodynamic noise that motor produces arrives piezoelectric part 7 by apertured partition 9, produces at the two ends of piezoelectric part 7
Potential difference, is converted into electrical power storage in electrical energy storage section 10 by noise, and remaining a small amount of energy flows from vent 6 with air
Walk.The most a small amount of electromagnetic noise and mechanicalness noise are propagated the most in atmosphere, the air in driving electric machine silencing means shell 4
