Description
Technical field
The utility model relates to a kind of device for testing motor noise, especially a kind of test motor noise for reducing resonance
Device.
Background technique
Motor can have different noise problems due to various reasons after assembly, such as divulge information noise, electromagnetic noise
Deng needing to carry out it detection of level of noise, some problems that motor remains can be found out by noise measuring, and then is right
It carries out perfect, and noise measuring result is also one of performance indicator of motor.Currently, to the detection of motor noise generally by motor
It is placed on levelling bench or it is clamped with frock clamp, place decibel instrument in the position away from motor certain distance and make an uproar to test
Value, still, the testing result of this detection mode will receive the influence of motor case resonance, so that testing result is inaccurate,
To make to analyze mistake, it is existing in noise problem that motor can not be found out.Therefore, there are motors to be total to for the detection of existing motor noise
Vibration be affected to noise measuring result, the problem that testing result accuracy is low.
Utility model content
The purpose of the utility model is to provide a kind of test motor noise devices for reducing resonance.It is total with motor
Vibration influences advantage small, that testing result accuracy is high to noise measuring result.
The technical solution of the utility model includes: a kind of test motor noise device for reducing resonance, including test bracket, test
Bracket is connected with the motor mounting tool being vacantly arranged through buffer strip, and motor mounting tool is surrounded by several decibel of test dress
It sets.
In a kind of test motor noise device reducing resonance above-mentioned, the motor mounting tool includes mounting plate, peace
Loading board is equipped with several cross bores, is mounted below mounting plate to measured motor.
In a kind of test motor noise device reducing resonance above-mentioned, two adjacent sides are embedded on the mounting plate
There is level meter.
In a kind of test motor noise device reducing resonance above-mentioned, the decibel test device and motor mounting tool
Etc. high settings, the distance between several decibel of test device and motor mounting tool it is all the same.
In a kind of test motor noise device reducing resonance above-mentioned, the decibel test device is connected with elevating lever.
In a kind of test motor noise device reducing resonance above-mentioned, the buffer strip and test bracket connecting portion are set
There is height adjustment mechanism.
In a kind of test motor noise device reducing resonance above-mentioned, the motor mounting tool hangs on test bracket
Intermediate position, the footing of test bracket is equipped with crash roll.
Compared with prior art, the utility model hangs motor mounting tool with multiple groups buffer strip on test bracket
Dress, is mounted on motor mounting tool to measured motor, forms the effect of suspension, in motor operation, can reduce casing resonance
Influence to noise measuring result is provided with several decibel of test device in the surrounding of motor mounting tool, these decibels are surveyed
Trial assembly is set all contour and equidistant with motor mounting tool, can be measured the level of noise in motor all directions, be efficiently solved
Motor keeps testing result accuracy higher due to the level of noise deviation in bring all directions in irregular shape, so as to
The objectively noise decibel value of test and analysis single-item motor.
In addition, the mounting plate of motor mounting tool is equipped with several cross bores, motor is mounted on by screw bolt and nut
Below mounting plate, according to different ratings of machine, size, motor can be neatly installed below mounting plate, make motor center of gravity
With mounting plate center on same plumb line, the inclination and offset of motor mounting tool are prevented, stability is higher, helps to be promoted
The accuracy of noise measuring result；On mounting plate two adjacent sides be embedded with level meter, can with real-time detection motor whether
It is mounted on optimum position；Buffer strip and test bracket connecting portion are equipped with height adjustment mechanism, can cooperate with level meter adjustment peace
The levelness of loading board makes to be horizontally mounted to measured motor；Decibel test device be connected with elevating lever, can make decibel test device with
Motor mounting tool is contour always；The footing of test bracket is equipped with crash roll, can reduce test bracket vibration and surveys to noise
The influence of test result.
To sum up, there is the utility model motor, which to resonate, influences high excellent of small, testing result accuracy to noise measuring result
Point.
