Description
Technical field
The utility model relates to centrifuge technique fields, more particularly, to a kind of use for laboratory damping centrifuge.
Background technique
For centrifuge using a kind of especially extensive instrument in life, the rotary drum high speed rotation of centrifuge generates centrifugal force,
Expand solid-liquid difference in specific gravity, achievees the effect that separation of solid and liquid；The centrifuge of experiment at present belongs to supercentrifuge, high speed centrifugation
Machine during rotation, can generate vibration, therefore the shock-absorbing function of centrifuge is had nothing in common with each other, such as CN201621263413.X public
A kind of laboratory centrifuge with shock-absorbing function opened is externally provided with bearing in rotary drum, and bearing is fixedly connected with the connecting rod,
Then it reconnects the bar other end and sets damping device, damping device is fixedly connected with centrifuge shell.Its damping effect is limited, and
Structure is excessively complicated, non-dismountable, extremely inconvenient when being replaced and cleaned.
Utility model content
Technical problem to be solved by the utility model is: it is simple to overcome the deficiencies of the prior art and provide a kind of structure, it is removable
It unloads, a kind of use for laboratory damping centrifuge of good damping effect.
The technical scheme adopted by the utility model to solve the technical problem is as follows: a kind of use for laboratory damping centrifuge, packet
Centrifuge shell is included, the inner cavity top of the centrifuge shell is equipped with spacing collar, and the intracavity bottom of the centrifuge shell is fixed
Motor housing is installed, motor is fixedly installed in the motor housing, the motor box cover is equipped with bearing, the motor output shaft
It is connect across bearing with rotary drum, the rotary drum top is embedded in spacing collar, and the bearing outer ring is equipped with one layer of yielding rubber circle.
Further, the motor housing is the rotary table or terrace with edge that coverage is less than base area, shape in the motor housing
At the cylinder or rectangular parallelepiped space for having installation motor.
Further, the ratio between the coverage and base area are less than or equal to 0.8.
Further, the base area is less than or equal to centrifuge enclosure bottom area.
Further, the motor box cover is equipped with thermal vias.
The utility model has the beneficial effects that
1. the utility model is externally provided with bearing and yielding rubber circle in motor output shaft, there is good damping effect.
2. setting internal for motor housing has cylindrical or rectangular parallelepiped space rotary table or terrace with edge, motor housing is reduced
Center of gravity so that whole device is more stable.
Detailed description of the invention
In order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below will be to embodiment
Or attached drawing needed to be used in the description of the prior art is briefly described, it should be apparent that, the accompanying drawings in the following description is only
It is some embodiments of the utility model, for those of ordinary skill in the art, in the premise not made the creative labor
Under, it is also possible to obtain other drawings based on these drawings.
Fig. 1-is a kind of use for laboratory damping centrifuge structure schematic diagram of the utility model.
Above-mentioned appended drawing reference: 1- centrifuge shell, 2- motor housing, 3- motor, 4- rotary drum, 5- bearing, 6- rubber ring, 7- limit
Position circle, 21- upper cover, 22- pedestal.
Specific embodiment
The following is a further explanation of the present invention with reference to the accompanying drawings and embodiments.
Referring to Fig.1, a kind of use for laboratory damping centrifuge of the present embodiment, including centrifuge shell 1, centrifuge shell 1
Inner cavity top be equipped with spacing collar 7, the intracavity bottom of centrifuge shell 1 is fixedly installed with motor housing 2, fixed peace in motor housing 2
Equipped with motor 3, motor housing 2 includes upper cover 21 and pedestal 22, and upper cover 21 is equipped with bearing 5, and 3 output shaft of motor passes through bearing 5 and turns
Drum 4 connects, and 4 top of rotary drum is embedded in spacing collar 7, and 5 outer ring of bearing is equipped with one layer of yielding rubber circle 6.
Motor housing 2 is the rotary table that 21 area of upper cover is less than 22 area of pedestal, 21 area of upper cover of motor housing 2 and 22 face of pedestal
The ratio between product is less than or equal to 0.8, while 22 area of pedestal is less than or equal to 1 base area of centrifuge shell.
Upper cover 21 is equipped with ventilative through hole.
The operation principle and using method of the utility model:
The utility model is externally provided with bearing and yielding rubber circle in motor output shaft, simply reaches very much damping purpose.
Motor is equipped in motor housing, motor housing is used to protect motor, and the power supply mode of motor is external power supply power supply, motor
Case is set as the big rotary table of upper cover small footprint, and the center of gravity of rotary table will be lower than the cylinder or cuboid of same volume, center of gravity more it is low just
It is more stable, so that whole device is more steady, equally also plays the effect of damping.
The ratio between coverage and base area are limited to the section less than or equal to 0.8 by the utility model, be by calculate,
Area ratio be 0.8 if, the ratio between radius just only about 0.9(because area be square of the π multiplied by radius, radius
The ratio between be exactly that area ratio opens what radical sign obtained) motor housing determine in the case where certain altitude, if the ratio between radius 0.9,
The degree of its center of gravity decline could intuitively influence damping effect.The ratio between radius be greater than 0.9 if, center of gravity decline degree and
Damping effect is not obvious, so being limited to area ratio less than or equal to 0.8；Base area is not more than centrifuge shell simultaneously
Base area, it is ensured that motor housing is capable of fixing in centrifuge shell.
The ventilative through hole for being located at motor box cover is to play the role of heat dissipation.
The utility model need to only start motor, the rotation of motor direct-drive rotary drum, and rotary drum produces during high speed rotation
Raw centrifugal force, thus achieve the effect that separation of solid and liquid, the vibration that rotary drum generates in rotary course, by yielding rubber circle and motor
The structure of case is offset, and the damping effect of a combination thereof is obvious, practical.
