Below with reference to Fig. 1-Fig. 7, dynamic vibration absorber 2 according to embodiments of the present invention is described.
As shown in Fig. 1-Fig. 7, the dynamic vibration absorber 2 of embodiment according to a first aspect of the present invention, including：Pedestal and mass
204.
Specifically, pedestal is spring leaf, so that pedestal has elasticity.Pedestal includes connected body and clamping part
203, clamping part 203 is formed as the annular with opening, and the shape of clamping part 203 can be mated according to the shape of pipeline 3,
Clamping part 203 can be annular or the polygonal annular with opening, and mass 204 is located on body.It is understood that by
It is spring leaf in the clamping part 203 of dynamic vibration absorber 2, therefore clamping part 203 has certain elasticity.Thus, power is being inhaled
When the device 2 that shakes is used for the pipe arrangement vibration damping of pipeline 3 such as compressor 100, directly the pipeline 3 needing vibration damping can be passed through clamping part
203 opening is engaged in clamping part 203, such that it is able to make dynamic vibration absorber 2 pass through the tight folder of clamping part 203 and pipeline 3
Hold effect and dynamic vibration absorber 2 is fixed on pipeline 3 so that dynamic vibration absorber 2 use and install extremely convenient, with
When be also convenient for the replacing of dynamic vibration absorber 2.And it is possible to the weight of the elasticity and mass 204 by changing spring leaf changes
The absorbing frequency of dynamic vibration absorber 2 is so that dynamic vibration absorber 2 is applied to the pipeline 3 of different vibration frequencies.
For example, when being used in above-mentioned dynamic vibration absorber 2 on the pipe arrangement of compressor 100, can pass through dynamic vibration absorber 2
Clamping part 203 is clamped on the pipe arrangement of compressor 100, such that it is able to dynamic vibration absorber 2 is fixed on the pipe arrangement of compressor 100
On.It is understood that when compressor 100 works, the pipe arrangement (such as blast pipe 12) of compressor 100 can produce vibration, lead to
Cross and above-mentioned dynamic vibration absorber 2 is arranged on the pipe arrangement of compressor 100, the effect of good vibration damping can be played, such that it is able to
Reduce noise.Compared with rubber counter weight being installed on the pipe arrangement of traditional compressor or pastes anti-vibration rubber, due to dynamic vibration absorber 2
It is by forming resonance with vibration damping object (such as pipeline 3), the vibration of object being made to subtract thus producing reaction force in resonance
Little, therefore adopt the vibration-absorbing denoising effect of dynamic vibration absorber 2 more preferable.
In addition, though also having using the dynamic vibration absorber dedicated for reduction pipeline vibration in prior art, but exist
Complex structure, the deficiency such as comprise that part is too many, be inconvenient to install.Comparatively speaking, dynamic vibration absorber 2 structure of the present invention simple,
Low cost and installation extremely convenient.
Alternatively, pedestal can be formed in one part, thus can simplify the moulding process of pedestal, reduces cost.Optional
Ground, mass 204 can be ironcasting or rubber parts, and mass 204 can be polyhedron (such as cube), spheroid, cylinder
Body, spheroid etc..
Dynamic vibration absorber 2 according to embodiments of the present invention, by its clamping part 203 being configured with the annular of opening,
Thus when being arranged on dynamic vibration absorber 2 on the such as pipe arrangement of compressor 100 on the pipeline 3 need vibration damping, only need to be by power
The clamping part 203 of bump leveller 2 is clamped directly at and gets final product so that dynamic vibration absorber 2 is easily installed on the pipeline 3 need vibration damping, and
And the vibration of pipeline 3 can be effectively reduced, this dynamic vibration absorber 2 also has the simple advantage of structure.
Describe the dynamic vibration absorber 2 according to the multiple embodiment of the present invention below with reference to Fig. 2-Fig. 7 in detail.Following multiple

2021 and second installing hole 2041 so that mass 204 to be connected with body.Thus, facilitate mass 204 to be arranged on body or
It is removed from the body so that the assembling of dynamic vibration absorber 2 is more convenient, be also convenient for the absorbing frequency of motivation of adjustment bump leveller 2 simultaneously
Rate.For example, in the absorbing frequency needing to change dynamic vibration absorber 2, the mass 204 on dynamic vibration absorber 2 can be taken off,
Reinstall the mass 204 varying in weight.
Clamping part 203 is formed as the annular with opening, and such as clamping part 203 can be formed as circular arc, clamping part 203
The middle part of beam portion 201 can be located at, beam portion 201 is segmented into upper and lower two parts, the two ends of clamping part 203 respectively with beam portion 201
Two parts up and down be respectively connected with.Certainly, clamping part 203 can also regard the direction at the middle part of beam portion 201 towards bow portion 202 as
It is bent to form.The central angle of clamping part 203 is α (with reference to Fig. 3), and α meets：360 ° of 180 ° of ＜ α ＜, such as α can be 240 °.By
This, by the setting of the central angle of clamping part 203 within the above range it is ensured that the clamping part 203 of dynamic vibration absorber 2 and pipeline 3
Holding area and claming angle so that dynamic vibration absorber 2 is firmly secured on pipeline 3.
Alternatively, the inner peripheral surface of clamping part 203 can be provided with pad 205, the inner peripheral surface of pad 205 and clamping part 203
Mating shapes.Thus, dynamic vibration absorber 2 is fixed on pipeline 3, vibration damping is carried out to pipeline 3 when, dynamic vibration absorber 2
Can be separated by pad 205 between clamping part 203 and pipeline 3, such that it is able to avoid dynamic vibration absorber 2 to connect with pipeline 3 rigidity
Touch, further reduce vibration.
