Abstract
The invention relates to a silencing top cover for a motor, which comprises two partitions fixedly bilaterally mounted at an interval. An outer casing plate is fixed at the top ends of the partitions, motor air inlet curve passages capable of outwards intaking air upwards obliquely and downwards blowing the air after direction is changed are arranged on the outer sides of the two partitions, motor air outlet curve passages capable of blowing the air in the middle upwards and downwards outwards blowing the air after direction is changed are arranged between the two partition plates, silencing perforated plates are arranged on the peripheral walls of the motor air inlet curve passages and the peripheral walls of the motor air outlet curve passages, and silencing cotton fillers are filled into the silencing perforated plates, among the silencing perforated plates and the outer casing plate and between the silencing perforated plates and the partitions. Running noise of the motor can be reduced evidently by the aid of the silencing structure consisting of the silencing cotton fillers and the silencing perforated plates, silencing single sheets arranged in an air outlet channel and the air inlet curve passages and the air outlet curve passages.
Description
Technical field
The present invention relates to a kind of cover body, especially a kind of motor is used the noise reduction overhead guard.
Background technology
In original technology, the shell of the alternating current machine overhead guard of the IC01 type of cooling is merely the steel plate of one deck 4 millimeter, does not do the noise reduction measure.When main motor moved, the noise that main motor produces was directly delivered in the environment through the window blind hatch of overhead guard.The noise ratio that is produced is more serious, and is more outstanding expressively in pot motor especially.
Summary of the invention
The objective of the invention is to overcome the deficiency that exists in the prior art, provide a kind of motor that can reduce motor operation noise to use the noise reduction overhead guard.
According to technical scheme provided by the invention; Said motor is used the noise reduction overhead guard; Be included in and be installed with on the base plate between left and right at a distance from the dividing plate that is provided with; Top at dividing plate is fixed with Shell Plate, and two dividing plate outsides are provided with the motor air intake Qu Lu that blows after external air inlet turns to obliquely downwards, is provided with between two dividing plates and blows the motor air-out Qu Lu that turns to the back also outwards to blow on the middle part downwards; Be provided with the noise reduction perforated plate at the perisporium of motor air intake Qu Lu and at the perisporium of motor air-out Qu Lu, between noise reduction perforated plate and Shell Plate, between noise reduction perforated plate and the dividing plate and be provided with the cotton obturator of noise reduction in the noise reduction perforated plate.
The cotton obturator of said noise reduction is the glass silk flosssilk wadding.The cotton obturator of said noise reduction is provided with the glass wool cloth of parcel usefulness outward.
The present invention passes in and out wind path simultaneously and has adopted Qu Lu because the noise-reducing structure that has adopted cotton obturator of noise reduction and noise reduction perforated plate to form is provided with the monolithic that disappears in the air-out air channel, can significantly reduce running noise of motor.
Description of drawings

Fig. 2 is the A-A cutaway view of Fig. 1.
Embodiment
Below in conjunction with concrete accompanying drawing and embodiment the present invention is described further.
As shown in the figure: this motor is used the noise reduction overhead guard; Be included in and be installed with on the base plate 1 between left and right at a distance from the dividing plate 2 that is provided with; Be fixed with Shell Plate 3 on the top of dividing plate 2; Two dividing plate 2 outsides are provided with the motor air intake Qu Lu that blows after external air inlet turns to obliquely downwards; Be provided with between two dividing plates 2 to blow on the middle part and turn to the back and the motor air-out Qu Lu that outwards blows downwards, be provided with noise reduction perforated plate 4, between noise reduction perforated plate 4 and Shell Plate 3, between noise reduction perforated plate 4 and the dividing plate 2 and be provided with noise reduction cotton obturator 5 in the noise reduction perforated plate 4 at the perisporium of motor air intake Qu Lu and at the perisporium of motor air-out Qu Lu.
The cotton obturator 5 of said noise reduction is the glass silk flosssilk wadding.The cotton obturator 5 outer glass wool cloths that are provided with parcel usefulness of said noise reduction.
The air inlet noise reduction: the air-flow trend of air intake is the shutter entering overhead guard that air passes through two ends, upwards turns to then, and tune gets into main motor air inlet downwards again.The noise reduction aspect, the noise that produces from the air inlet of main motor upwards is delivered to the overhead guard space, around the motor air intake Qu Lu of overhead guard, all is provided with the cotton obturator 5 of noise reduction, the parcel noise-reducing structure with glass wool cloth and noise reduction perforated plate 4.The cotton obturator 5 of noise reduction is equivalent to a resistance noise reduction effect, absorbs high-frequency noises.Noise reduction perforated plate 4 is equivalent to a reactive muffler, absorbs the Low Medium Frequency noise, and both combine, and are equivalent to form a complex muffler, can effectively reduce the noise that motor spreads out of.When sound wave outwards transmits simultaneously, pass through the motor air intake Qu Lu of top again again, eliminated direct sound wave.
The air outlet noise reduction: air-flow that main motor rotation produces and noise are through upwards reversing end for end behind noise reduction perforated plate 4 downwards and outwards blowing; Shutter through the overhead guard both sides blows out again, all is provided with the cotton obturator 5 of noise reduction around the motor air-out Qu Lu, wraps up the noise-reducing structure with glass wool cloth and noise reduction perforated plate 4.The cotton obturator 5 of noise reduction is equivalent to a resistance noise reduction effect, absorbs high-frequency noises.Noise reduction perforated plate 4 is equivalent to a reactive muffler, absorbs the Low Medium Frequency noise, and both combine; Be equivalent to form a complex muffler, can effectively reduce the noise that motor spreads out of, when sound wave outwards transmits simultaneously again; Pass through the motor air-out Qu Lu of top again, eliminated direct sound wave.
