Abstract
The utility model discloses a hydraulic actuator on a centrifugal machine. The hydraulic actuator comprises a rotor, a stator and a bearing gland, wherein the rotor is fixedly connected with a rotating shaft by a bolt, and is provided with a plurality of movable plungers, oil cavities are arranged in the plungers, an oil distribution shaft is arranged in the rotor and is internally provided with oil distribution pipes, the oil distribution pipes are communicated with the oil cavities in the plungers, rollers are arranged at the top of the plungers, the inner surface of the stator is of a curved guiderail surface, and rollers are supported on the curved guiderail surface. The hydraulic actuator can be easily adjusted by changing the flow rate of input hydraulic oil, the productivity and separation effect are both greatly improved through two low-rotating speed and large-torque hydraulic actuators, hydraulic oil is adopted as media for transferring torque, the hydraulic actuator belongs to flexible transmission, and is low in noise, can work under the condition that the minimum differential speed being 0.5-1r/min of a rotary drum and a helix, and can treat difficultly separable materials.
Description
Technical field
The utility model relates to the centrifuge field, particularly the hydraulic unit driver on a kind of centrifuge.
Background technology
Horizontal spiral discharge sedimentation centrifuge, to utilize the principle of centrifugal sedimentation to realize the equipment that solid-liquid suspension separates, it passes through screw feeder, outside the continuous kickoff mechanism of solid-phase material that centrifugal sedimentation is separated, screw feeder need to together rotate along with rotary drum, simultaneously again and keep certain relative speed difference between the rotary drum, driver is exactly a special transmission device that guarantees to have between rotary drum and screw feeder speed difference.Mostly people are with traditional thermo-mechanical drive now, and the rotating speed of the general output of thermo-mechanical drive is fixed, and are difficult for adjusting, if adjust the differential of rotary drum and screw feeder, must shut down first, then change belt pulley again.Traditional thermo-mechanical drive is owing to adopting two fixing differentials, so in case the inlet amount of suspension or solid content are unstable, easily cause the damage of thermo-mechanical drive, thereby make centrifuge generation putty, bring certain trouble for people's production, horizontal screw centrifuge is a kind of machinery of High Rotation Speed, and noise is generally between 85～90db, noise is relatively large, and people's working environment has been caused noise pollution.
Summary of the invention
In order to overcome defects, the utility model provides a kind of difficult generation putty, and set noise is low, the hydraulic unit driver on the centrifuge that is easy to realize automatically controlling.
The utility model for the technical scheme that solves its technical problem and adopt is: the hydraulic unit driver on a kind of centrifuge, comprise rotor, stator and bearing gland, described rotor is bolted to connection turning cylinder, described rotor is provided with the plunger of some activities, be provided with oil pocket in the plunger, be provided with an oil distribution shaft in the described rotor, be provided with oil distributing pipe in the oil distribution shaft, oil distributing pipe is communicated with the oil pocket in the plunger, the top of plunger is provided with roller, the inner surface of stator is the curvilinear guide face, and roller pushes against in the curvilinear guide face.
As further improvement of the utility model, be tightly connected between described plunger and rotor.
As further improvement of the utility model, the junction of described bearing gland and oil distribution shaft is provided with the fine setting cam of an adjustment oil distribution shaft axial location.
The beneficial effects of the utility model are: hydraulic unit driver of the present utility model then can be by changing the flow of input hydraulic pressure oil; adjusted at an easy rate; differential between rotary drum and the screw feeder does not need to shut down just can be adjusted arbitrarily; owing to adopting two slow-speed of revolution; the hydraulic unit driver of high pulling torque; the machine of therefore same specification; under the condition of equal separation factor; its production capacity; separating effect all is greatly improved; hydraulic unit driver is owing to adopting hydraulic oil as the medium of transmitting torque; belong to Flexible Transmission; its noise is lower, and generally between 80～85db, the differential of hydraulic unit driver can reach 1～10r/min; the minimum differential that is to say rotary drum and spiral carries out work under the condition of 0.5～1r/min again, can process difficult separation of material.

The specific embodiment
In order to deepen understanding of the present utility model, the utility model is described in further detail below in conjunction with embodiment and accompanying drawing, and this embodiment only is used for explaining the utility model, does not consist of the restriction to the utility model protection domain.
Fig. 1-2 has shown a kind of embodiment of the hydraulic unit driver on a kind of centrifuge of the utility model, comprise rotor 1, stator 2 and bearing gland 3, described rotor 1 is bolted to connection turning cylinder 4, described rotor 1 is provided with the plunger 5 of some activities, be provided with oil pocket 51 in the plunger 5, be provided with an oil distribution shaft 6 in the described rotor 1, be provided with oil distributing pipe 61 in the oil distribution shaft 6, the oil pocket 51 that oil distributing pipe 61 is communicated with in the plunger 5, the top of plunger 5 is provided with roller 7, the inner surface of stator 2 is curvilinear guide face 8, roller 7 pushes against in curvilinear guide face 8,1 of described plunger 5 and rotor are tightly connected, and the junction of described bearing gland 3 and oil distribution shaft 6 is provided with the fine setting cam 9 of an adjustment oil distribution shaft 6 axial locations.
Operation principle of the present utility model is, hydraulic oil enters in the oil pocket 51 of plunger 5 by the oil distributing pipe 61 of oil distribution shaft 6, thereby it is outwards mobile to promote plunger 5, the roller 7 at plunger 5 tops pushes against in the curvilinear guide face 8 of stator 2 inside, under the effect of high pressure oil, make the roller 7 of plunger 5 hold out against curvilinear guide face 8, produce normal reaction N at contact point upper curve guide pass 8 pair rollers 7, roller 7 centers are also passed through in its perpendicular direction curvilinear guide face 8 surfaces, this power can be decomposed into two component, along the axial component P of plunger 5 with perpendicular to the component T of plunger 5 axis, it passes to stator by the crossbeam side, stator 2 is produced moment, so that rotor 1 rotates under the drive of roller, rotor 1 drives turning cylinder 4 again and rotates output, and 1 of plunger 5 and rotor are tightly connected, not leak outside in the process of circulation of assurance hydraulic oil in driver.
