Abstract
The utility model relates to a centrifugal machine with a damping device. The centrifugal machine with the damping device comprises a cover shell, a motor and a rotary drum. The motor is connected with the rotary drum through the damping device. The damping device comprises a shaft sleeve and a bearing placed in the shaft sleeve. A precise positioning ring with elasticity is arranged between the shaft sleeve and the bearing. An elastic structure is arranged inside the precision positioning ring. A plurality of protrusions are arranged on the outer surface of the precision positioning ring. Compared with the prior art, the centrifugal machine with the damping device has the advantages that the precision positioning ring with the elasticity is arranged between the bearing and the shaft sleeve so that when a rotor deviates, the rotor can be corrected, circumferential stress between the bearing and the shaft sleeve is reduced, vibration is absorbed and noises are reduced and the plurality of protrusions are arranged on the outer surface of the precision positioning ring so that when the protrusions are extruded, springback can be achieved, and therefore deviation of the rotor is corrected and vibration and noises can be further reduced.
Description
Technical field
The utility model relates to a kind of centrifuge, particularly a kind of centrifuge with damping device.
Background technology
Centrifuge is to utilize centrifugal force, the machinery of each component in the mixture of separating liquid and solid particle or liquid and liquid.Centrifuge is mainly used in the solid particle in the suspension and liquid are separated; Or with two kinds of density differences in the emulsion, immiscible liquid separates (for example isolating cream from milk) again; It also can be used for getting rid of the liquid in the wet solid, for example dries wet clothes with washing machine; Special hypervelocity channel separator is the admixture of gas of separable different densities also; Utilize the different characteristics of solid particle sinking speed in liquid of different densities or granularity, the sedimentation centrifuge that has also can carry out classification by density or granularity to solid particle.Centrifuge is widely used in the departments such as chemical industry, oil, food, pharmacy, ore dressing, coal, water treatment and boats and ships.Centrifuge is accounting for critical role always in mechanical field at present.On various International exhibitions, various centrifuges are the most noticeable.It generally is the equipment for after-treatment in the technological process, is directly connected to the quality of final products, is widely used in biological study and industrial production.
During at present centrifuge operation, the fluctuation of driven by motor rotary drum generation torque can cause vibration and the noise of bowl, case and whole movement system, has reduced the comfortableness of working environment, affects the handling and security of centrifuge.Simultaneously, the motor antivibration requires harsh, and when running up owing to centrifuge, rotary drum will bear very large shock loading, and present centrifuge can not satisfy the antivibration requirement, and the life-span of motor is short.
Summary of the invention
The utility model is for solving above-mentioned technical problem of the prior art, the technical scheme that adopts is: a kind of centrifuge with damping device, comprise case, motor, rotary drum, it is characterized in that: described motor is connected a damping device and connects with rotary drum, described damping device comprises axle sleeve and the bearing that places in the described axle sleeve, is provided with between described axle sleeve and the described bearing to have flexible precision positioning circle.
Further, described bearing is made by engineering plastics.
Further, described precision positioning circle inside has elastic construction.
Further, the outer surface of described precision positioning circle is formed with a plurality of projections.
Further, described projection is conical.
Compared with prior art, the utility model has the advantage of: setting has flexible precision positioning circle between bearing and axle sleeve, when rotor displacement, can correct, and reduces the circumferential stress between bearing and the axle sleeve, can attract vibrations, noise decrease; Bearing adopts engineering plastics to replace metal material commonly used and makes, and has elasticity, the noise that sends in the time of therefore can reducing the collision of bearing and rotor.The outer surface of precision positioning circle is formed with a plurality of projections, thereby the skew of can resilience when being squeezed correcting rotor can further reduce vibrations and noise.
Description of drawings
Figure l is the partial structurtes schematic diagram of the utility model damping device.
In the accompanying drawing, 1-axle sleeve, 2-bearing, 3-precision positioning circle, 4-projection.
The specific embodiment
Embodiment is described in further detail the utility model below in conjunction with accompanying drawing.
As shown in Figure 1, a kind of centrifuge with damping device, comprise case, motor, rotary drum, it is characterized in that: described motor is connected a damping device and connects with rotary drum, described damping device comprises axle sleeve 1 and the bearing 2 that places in the described axle sleeve 1, be provided with between described axle sleeve 1 and the described bearing 2 and have flexible precision positioning circle 3, described bearing 2 is made by engineering plastics, has elasticity, therefore the noise that sends in the time of can reducing the collision of bearing 2 and rotor, preferred, bearing 2 adopts composite engineering plastics to make.Setting has flexible precision positioning circle 3 between bearing 2 and axle sleeve 1, when rotor displacement, can correct, and reduces the circumferential stress between bearing 2 and the axle sleeve 1, can attract vibrations, noise decrease.Described precision positioning circle 3 inside have elastic construction, and the outer surface of described precision positioning circle 3 is formed with a plurality of projections 4, and described projection is conical, thereby the skew of can resilience when being squeezed correcting rotor can further reduce vibrations and noise.Bearing 2 has elasticity, the vibrations and the noise that send in the time of therefore can reducing the collision of bearing 2 and rotor.
The above only is preferred embodiment of the present utility model; should be pointed out that for the ordinary skill in the art, do not breaking away under the principle prerequisite of the present utility model; can also make various deformation and improvement, this also is encompassed in the protection domain of the present utility model.
