Description
Technical field
The utility model belongs to damper technical field, and in particular to a kind of company for reducing motor and cooler resonance
Connection device.
Background technology
Currently, the cooler of domestic conventional motor connect with engine base and is substantially all by being bolted, only adopted between mounting plate
Mechanical seal has been carried out with washer, has alleviated the function of motor body structural vibration without playing.When motor rotary speed compared with
When being changed in big range, resonance risk is easily generated, this generates harm to motor, or even can seriously affect the normal fortune of motor
Row and service life.
Meanwhile the dashpot of domestic production is required to increase in equipment corresponding weight to meet weakening effect, this is needed
Pay a large amount of material cost.It is certain have strict demand to weight of equipment in the environment of, conventional vibration damping, vibration damping device are past
It is past to cannot be satisfied requirement.
Utility model content
The purpose of this utility model is to provide a kind of attachment device for reducing motor and cooler resonance, the dresses
Connection, fixed cooler and motor can not only be played the role of by setting, additionally it is possible to be reduced the resonance between cooler and motor, be protected
The normal operation of motor is demonstrate,proved.
To achieve the above object, the utility model uses following technical scheme：
A kind of attachment device for reducing motor and cooler resonance, including several bolts and from top to bottom put down
The cooler bottom plate and motor mounting plate of row setting, the bolt pass through cooler bottom plate and motor mounting plate and with cooler bottom
Plate and motor mounting plate are threadedly coupled；It is arranged with the first eliminating mechanism and the second eliminating mechanism outside each bolt, described first
For eliminating mechanism between cooler bottom plate and the nut of bolt, second eliminating mechanism is located at cooler bottom plate and motor peace
Between loading board, the part that the bolt tail is pierced by motor mounting plate is connected with the first nut.
First eliminating mechanism includes the elastomeric pad below the nut of bolt, the below elastomeric pad
One plain washer and the first damping sleeve below the first plain washer, first damping sleeve are arranged with the first spring outside.
Second eliminating mechanism include be located at cooler bottom plate below the second damping sleeve and be set to the second damping sleeve
Second plain washer of lower section, second damping sleeve are arranged with second spring outside.
Further, the second nut is equipped between second plain washer and motor mounting plate.
Further, the bolt tail is pierced by the part connection of motor mounting plate there are two the first nut.
The beneficial effects of the utility model：
1）The utility model is arranged with the first eliminating mechanism and the second eliminating mechanism above and below in cooler bottom plate, will cool down
Device is divided into two independent vibrational systems with motor, by adjusting the dynamic characteristic of spring and damping sleeve, can reduce motor
The vibration of ontology, within the allowable range by the amplitude controlling of motor body.
2）It when motor operation, is especially run in larger operating rotational speed range, which can ensure electricity
The vibration severity of machine ontology is reduced to the range of requirement, it is ensured that variable-frequency motor is accomplished to run steadily in the long term in each working speed；
Through simulation analysis and verification experimental verification, the peak swing of motor body can be reduced by 60% or more by the present apparatus.
3）Cooler is pressed on above motor when the utility model is installed, using cooler as mass elements, the first weakening machine
Structure and the second eliminating mechanism no longer need additionally to increase counterweight, keep its structure simpler, effectively reduce cost.
Description of the drawings
Fig. 1 is attachment device structural schematic diagram described in the utility model；
Fig. 2 is the structural schematic diagram of the first eliminating mechanism and the second eliminating mechanism described in Fig. 1.
Specific implementation mode
A kind of attachment device for reducing motor and cooler resonance, as shown in Figs. 1-2, including bolt 3 and by upper
Cooler bottom plate 1 and motor mounting plate 2 disposed in parallel under, the bolt 3 pass through cooler bottom plate 1 and motor mounting plate 2
And it is threadedly coupled with cooler bottom plate 1 and motor mounting plate 2.
The first eliminating mechanism 4 and the second eliminating mechanism 5 are arranged with outside the bolt 3, first eliminating mechanism 4 is located at cold
But between device bottom plate 1 and the nut of bolt 3, second eliminating mechanism 5 between cooler bottom plate 1 and motor mounting plate 2,
First eliminating mechanism 4 and the second eliminating mechanism 5 set up separately in 1 upper and lower of cooler bottom plate, and cooler and motor are divided into two
Independent vibrational system.
The part that 3 tail portion of the bolt is pierced by motor mounting plate 2 is connected with the first nut 7.In the present embodiment, the bolt
3 tail portions are pierced by the part connection of motor mounting plate 2 there are two the first nut 7, and the design of two nuts can prevent bolt and spiral shell
It is loosened between mother.
First eliminating mechanism 4 includes being located at the elastomeric pad 41 below the nut of bolt 3, being set under elastomeric pad 41
First plain washer 42 of side and the first damping sleeve 43 below the first plain washer 42,43 housing of the first damping sleeve
Equipped with the first spring 44.
Second eliminating mechanism 5 includes the second damping sleeve 52 for being located at 1 lower section of cooler bottom plate, is set to the second damping sleeve
52 and the lower section of second spring 51 the second plain washer 53, be arranged with second spring 51 outside second damping sleeve 52.
In the present embodiment, the second nut 6, second spiral shell are equipped between second plain washer 53 and motor mounting plate 2
Mother 6 ensure that the first eliminating mechanism 4 and the second eliminating mechanism 5 can be firmly installed on cooler bottom plate 1.
When cooler and motor are assembled, first the first eliminating mechanism 4 will be put on outside bolt 3, be then passed through cooler bottom
Plate 1 then covers upper second eliminating mechanism 5 outside bolt 3 and is fastened with the second nut 6；Last bolt passes through motor mounting plate 2 simultaneously
It is fixed with two the first nuts 7.The present apparatus can reduce shaking for motor body by adjusting the dynamic characteristic of spring and damping sleeve
It is dynamic.
Above example be only for reduce motor and cooler resonance attachment device preferred embodiment, not to
Limit the scope of protection of the utility model.It will be understood by those of ordinary skill in the art that the technical solution of the utility model
It is modified or replaced equivalently, without departing from the spirit and scope of technical solutions of the utility model.
