Description
Technical field
The invention belongs to noise reduction technology field, and in particular to a kind of air Compressor unit for reducing mechanical resonance.
Background technology
Causing for mechanical resonance is due to rigid difference, that is to say, that the responsiveness of two objects is different, and any two
The system of individual object composition has their resonant frequency, once reaching, will resonate.This depends under normal circumstances
In the bandwidth of controller.If the gain of servo-driver is increased sufficiently to reach resonant frequency, machine is just
Start to resonate.
Because inertia in high frequency can reduce with the reduction of frequency.When low frequency, action response
Substantially no error.So inertial change from low to high result in the problem of unstable.Just
As we have seen that motor and load between a variety of transfer units be present, these transfer units are weighed with elastic size
The size of their rigidity.So the elimination of a resonance improves overall resonant frequency, generally mean
And add elastic stiffness.The method for reducing resonance at present takes reinforcement mechanical structure rigidity to reduce asking for resonance
Topic, but the method can cause design cost to increase, while damping effect unobvious.
The content of the invention
It is an object of the present invention to overcome the above-mentioned drawbacks of the prior art and provide one kind reduces machinery altogether
The air Compressor unit to shake.
The purpose of the present invention can be achieved through the following technical solutions：
A kind of air Compressor unit for reducing mechanical resonance, including air compressor machine, fixed support and cabinet, described pneumatics
Machine is connected with fixed support, in addition to dampening assembly, and described fixed support passes through dampening assembly and the bottom plate of cabinet
Connection.
Described dampening assembly includes the first stud, the second stud, elastic fluid block and spring, the first described spiral shell
The baffle plate of post and the second stud by cylinder and positioned at cylinder bottom is formed, and the first stud and the second stud are coaxially set
Put, baffle plate is located in elastic fluid block, and described spring is located in elastic fluid block, both ends respectively with the first stud
Baffle plate and the second stud baffle plate contact.
Described elastic fluid block is organic silico briquette, cylindrical.
Described the first stud and the second stud is connected by nut with fixed support and cabinet respectively.
Flat shim is provided with positioned at the elastic fluid block surface of the first stud side, the flat shim is set in the post of the first stud
On body.
Described dampening assembly also includes being located at the upper of baffle plate around the baffle edge folding portion of one week, described folding portion
Surface.
The present invention reduces mechanical resonance by setting dampening assembly between mounting bracket and the bottom plate of cabinet.Pneumatics
Pump inside machine can produce strenuous vibration, the first stud of dampening assembly and the installation branch of air compressor machine when extracting air
The close connection of seat, the vibroseis that the vibrations of air compressor machine are produced, conducts to the first stud, then by having higher elasticity
Elastic fluid block (organic silico briquette) and spring, be transferred to the chassis backplane being connected with the second stud after decrease,
Resonant frequency is reduced with this, to reach the effect of damping.
Because the first stud and the second stud do not contact, the weight of air compressor machine is transferred to cabinet bottom by elastic fluid block
On plate, because air compressor machine weight is larger, so that the decrement of elastic fluid block is larger, have lost elastic fluid
Most of elastic performance of block；The present invention sets spring between the baffle plate of two studs, and one is undertaken by spring
Divide the weight of air compressor machine, slow down compression of the air compressor machine to elastic fluid block, its elastic performance is played to elastic fluid block
Play good booster action.
Flat shim is used for the loading end for increasing elastic fluid block, disperses pressure, is more uniformly stressed compression face, by
Contacted in the elastic fluid block surface positioned at the second stud side with chassis backplane, therefore plain cushion need not be set in the face
Piece can also make the compression face uniform force of elastic fluid block.
The present invention strengthens the resistance to lateral bending performance of dampening assembly by setting folding portion.
Compared with prior art, the present invention has advantages below：
(1) due to adding dampening assembly between air compressor machine and fixed support, machinery and exciting source can be avoided
Resonate.The tensile strength of the organic silico briquette used simultaneously using the present invention can reach 24.5~34.3MPa,
And elasticity can be kept in the range of very wide temperature (- 50~150 DEG C), organosilicon is than rubber more resistant to high temperature, energy
Greatly increase the service life.The main chain of organosilicon is-Si-O- simultaneously, and no double bond is present, its chemical constitution for this
It is more stable, it is not easy, by ultraviolet light degradation, toxic gas will not be also given out as rubber.
(2) elastic fluid block (organic silico briquette) and spring collective effect, can be played while weight is carried
Preferable elastic performance, while there is preferable resistance to lateral bending performance.
