Description
Technical field
This utility model belongs to noise reduction technology field, is specifically related to a kind of air compressor machine dress reducing mechanical resonance
Put.
Background technology
Causing of mechanical resonance is the difference due to rigidity, say, that the responsiveness of two objects is different, any two
The system of individual object composition has their resonant frequency, once reaches, will resonate.This depends under normal circumstances
Bandwidth in controller.If the gain of servo-driver is increased sufficiently to reach resonant frequency, machine is just
Start resonance.
This is because inertia in high frequency can reduce along with the reduction of frequency.Low frequency when, action response
Substantially there is no error.So, the problem that inertial change from low to high result in instability.Just
As there is multiple transfer unit between the motor that we have seen that and load, these transfer units are weighed with elastic size
The size of their rigidity.So, the elimination of a resonance improves the resonant frequency of entirety, generally means
And add elastic stiffness.The method reducing resonance at present is taked to strengthen frame for movement rigidity to reduce asking of resonance
Topic, but the method can cause design cost to increase, and damping effect is inconspicuous simultaneously.
Summary of the invention
Defect that the purpose of this utility model is contemplated to overcome above-mentioned prior art to exist and a kind of minimizing machine is provided
The air Compressor unit of tool resonance.
The purpose of this utility model can be achieved through the following technical solutions:
A kind of air Compressor unit reducing mechanical resonance, including air compressor machine, fixed support and cabinet, described pneumatics
Machine is connected with fixed support, also includes dampening assembly, and described fixed support is by the base plate of dampening assembly with cabinet
Connect.
Described dampening assembly includes the first stud, the second stud, elastic fluid block and spring, the first described spiral shell
Post and the second stud by cylinder and are positioned at the baffle plate composition bottom cylinder, and the first stud and the second stud coaxially set
Putting, baffle plate is positioned at elastic fluid block, and described spring is positioned at elastic fluid block, two ends respectively with the first stud
Baffle plate and the second stud baffle plate contact.
Described elastic fluid block is organic silico briquette, cylindrical.
The first described stud and the second stud are connected with fixed support and cabinet by nut respectively.
The elastic fluid block surface being positioned at the first stud side is provided with flat shim, and this flat shim is set in the post of the first stud
On body.
Described dampening assembly also includes that, around the baffle edge folding portion of a week, described folding portion is positioned at the upper of baffle plate
Surface.
This utility model reduces mechanical resonance by arranging dampening assembly between mounting bracket and the base plate of cabinet.
Pump within air compressor machine can produce strenuous vibration when extracting air, the first stud of dampening assembly and the peace of air compressor machine
Dress bearing compact siro spinning technology, the vibroseis that the vibrations of air compressor machine are produced, conduction is to the first stud higher through having
Elastic elastic fluid block (organic silico briquette) and spring, be transferred to after weakening at the bottom of the cabinet being connected with the second stud
Plate, reduces resonant frequency with this, to reach the effect of damping.
Owing to the first stud and the second stud do not contact, the weight of air compressor machine is transferred at the bottom of cabinet by elastic fluid block
On plate, owing to air compressor machine weight is relatively big, the decrement so making elastic fluid block is relatively big, have lost elastic fluid
Most of elastic performance of block；This utility model arranges spring between the baffle plate of two studs, is undertaken by spring
The weight of a part of air compressor machine, slows down the air compressor machine compression to elastic fluid block, elastic fluid block plays it elastic
Performance plays good assosting effect.
Flat shim, for increasing the loading end of elastic fluid block, dispersive pressure, makes compression face be more uniformly stressed, by
Contact with chassis backplane in the elastic fluid block surface being positioned at the second stud side, therefore need not arrange plain cushion in this face
Sheet also can make the compression face uniform force of elastic fluid block.
This utility model strengthens the resistance to lateral bending performance of dampening assembly by arranging folding portion.
Compared with prior art, this utility model has the advantage that
(1) owing to adding dampening assembly between air compressor machine and fixed support, machinery and exciting source can be avoided
Resonate.The hot strength of organic silico briquette simultaneously using this utility model to use can reach 24.5～
34.3MPa, and can keep elastic in the range of the widest temperature (-50～150 DEG C), organosilicon is than rubber more
High temperature resistant, can greatly increase the service life.The main chain of organosilicon is-Si-O-simultaneously, exists without double bond, for this it
Chemical constitution more stable, be difficult to by ultraviolet light degradation, also will not give out toxic gas as rubber.
(2) elastic fluid block (organic silico briquette) and spring act on jointly, it is possible to play while carrying weight
Preferably elastic performance, has preferable resistance to lateral bending performance simultaneously.
