Abstract
The utility model relates to a noise reduction motor cover in motor field, this motor cover is equipped with the shaft hole to and distribute in the louvre of shaft hole circumference, motor cover outer end sealing connection amortization lid, amortization lid outer end is equipped with the exhaust hole, forms the amortization chamber between amortization lid inboard and the motor cover outer end, and the amortization pipe fitting is connected in the one end of amortization intracavity to the exhaust hole site. Through addding the amortization lid on the basis at current motor cover to set up the amortization pipe fitting, thereby play noise reduction device's effect, effectively reduce spreading out of of motor cover noise.
Description
Technical field
This utility model is related to motor, especially a kind of with the noise abatement motor cover for suppressing noise.
Background technology
Motor cover is exactly the lid of motor one end as its name suggests, by the lid, facilitates the integral installation of motor to match somebody with somebody.Motor exists
Noise can be produced during work unavoidably, and the main generation position of noise is motor cover, due to most of motor cover outer ends it is equal
Louvre is set, therefore mechanicalness noise and electromagnetic noise are easiest to spread out of from there.For this purpose, needing to change existing motor cover
Enter.
The content of the invention
For overcoming above-mentioned deficiency, this utility model to design a kind of noise abatement motor cover so as to solve existing motor cover because being provided with
Louvre and cause noise to spread out of excessive technical problem.Which adopts the following technical scheme that realization.
The noise abatement motor is covered with axis hole, and is distributed in the circumferential louvre of axis hole, and the motor cover outer end sealing connects
Noise reduction lid is connect, noise reduction lid outer end is provided with steam vent, on the inside of noise reduction lid, form silencing cavity, the row and the motor cover outer end between
Pore is located at one end joint noise reduction pipe fitting of noise reduction intracavity.By setting up noise reduction lid on the basis of existing motor cover, and arrange
Sound deadening pipe fitting, so as to play a part of noise abatement noise reduction, effectively reduces spreading out of for motor cover noise.Meanwhile, noise reduction lid is not sealed completely
The louvre of motor cover is closed, the impact to radiating is less.
The silencing cavity is separated to form left and right two chambers by dividing plate, and dividing plate is provided with conducting left chamber, the through hole of right chamber,
Sound deadening pipe fitting is set, and the left chamber is communicated with the louvre, the sound deadening pipe fitting phase of the right chamber and the steam vent in through hole
It is logical.By the structure, so as to form two grades of noise reductions, the effect of noise abatement noise reduction is improved.
Hush pipe in the louvre aperture of the mouth of pipe of sound deadening pipe fitting and the motor cover and the steam vent in the through hole
The mouth of pipe of part is not relative.By the structure, further to improve the effect of noise reduction noise abatement.
Clamp when the dividing plate is fixed with the motor cover with the noise reduction lid and be limited in noise reduction lid, the structure install compared with
For convenience.
The noise reduction lid is heat-conducting piece, and the uniform fin of noise reduction cover outer wall.By the structure, using the heat conduction of noise reduction lid simultaneously
Coordinate radiating of the fin quickening to noise reduction intracavity, so as to overcome because setting up noise reduction lid outside motor cover, and cause louvre to be arranged
The heat for going out accumulates in the problem of the more difficult quick heat radiating of noise reduction intracavity.
This utility model can effectively suppress the noise that motor cover spreads out of, and improve the use environment of motor.

Specific embodiment
In conjunction with accompanying drawing, this utility model is described as follows.
As shown in figure 1, the noise abatement motor is covered with axis hole 101, and is distributed in the louvre 102 of 101 circumference of axis hole, electricity
1 outer end of cover is tightly connected noise reduction lid 2 by bolt part and sealing member, and 2 outer end of noise reduction lid is provided with steam vent 202, in noise reduction lid 2
Silencing cavity 201 is formed between 1 outer end of side and motor cover, and one end that steam vent 202 is located in silencing cavity 201 is fixedly connected hush pipe
Part 3.
As shown in Fig. 2 the effect in order to improve noise reduction, silencing cavity 201 is separated to form left and right two chambers by dividing plate 4,
And dividing plate 4 is clamped when being fixed with motor cover 1 with noise reduction lid 2 and is limited in noise reduction lid 2.It is left that dividing plate 4 is provided with circumferentially distributed conducting
Chamber 2011, the through hole of right chamber 2012, fix sound deadening pipe fitting 3 in through hole, left chamber 2011 is communicated with louvre 102, right chamber 2012 with
The sound deadening pipe fitting 3 of steam vent 202 is communicated, and 102 aperture of louvre of the mouth of pipe of sound deadening pipe fitting 3 and motor cover 1 and row in through hole
In pore 202, the mouth of pipe of sound deadening pipe fitting 3 is not relative.
In order to make up the problem that motor cover 1 causes 1 radiating effect of motor cover to weaken because outside sets up noise reduction lid 2, noise reduction
Lid 2 adopts heat-conducting piece, and the uniform fin 203 of outer wall, fin 203 is contacted with extraneous air, accelerates in silencing cavity 201
Radiating, improve integral heat sink performance.
