Description
Technical field
The utility model is related to Centrifuge Techniques field, more particularly to a kind of centrifuge damping device.
Background technology
Centrifuge is that the centrifugal force that produces reaches the one kind separated to different densities material when being rotated at a high speed by rotor
Equipment.Due to the machining accuracy of component, rigging error and load error etc., centrifuge produce unavoidably in the course of the work low frequency or
The vibrations of high frequency, so as to influence centrifuge stable working.Conventional centrifuge can be produced very in acceleration and deceleration process low-speed stage
Big vibrations and noise, particularly when loading larger, can produce very big swing, or even have unbalance risk.
In summary, prior art there will naturally be inconvenience and defect in actual use, and it is therefore necessary to improved.

Pallet is installed, the pallet center is fixed with motor, the motor driven rotor body rotation；The base and pallet）Between
Provided with rubber absorbers and spring vibration damper, four spring vibration dampers are distributed into even circumferential；It is embedding on the pallet
There is ball, the ball is against the rotor block bottom, and four balls are distributed into even circumferential；The ball subtracts with spring
Shake device is distributed on same circumference, and the ball is spaced apart with spring vibration damper.
As preferred technical scheme, adjacent ball central angle corresponding with the spring vibration damper spacing is
45°。
As preferred technical scheme, the ball exposes the corresponding center of circle in the tray upper surface part on vertical cross-section
Angle is 130 °.
As preferred technical scheme, the rubber absorbers are cylinder, and the rubber absorbers are limited through screens groove
In the middle position of pallet.
As preferred technical scheme, the spring vibration damper includes bolt, base and support described in the bolt connection
It is relative on disk, the base and pallet to be provided with positive stop lug boss one, positive stop lug boss two, the positive stop lug boss one and positive stop lug boss two it
Between be arranged with spring, the bolt passes through positive stop lug boss one, positive stop lug boss two and spring.
Damping device of the present utility model is combined in non-hard contact condition and with reliable using spring damper with ball
Ground stability, can effectively eliminate the vibrations of frequency low-amplitude degree, and rubber absorbers change the direction of vibrations, greatly reduce
Amplitude of fluctuation during centrifuge heavy load low speed, so as to ensure that the even running of centrifuge.
