Abstract
The utility model relates to a liquid controlling device for an electric control hydraulic actuator, belonging to a hydraulic control device. The liquid controlling device for the electric control hydraulic actuator comprises a motor, a gear pump and an oil storage box. The motor and the gear pump are respectively fixed on a machine base, and the motor and the gear pump are connected with the machine base. A cyathiform oil storage box cover is arranged on the gear pump and the machine base, and two rigid pipelines are respectively fixed at both sides of the gear pump; O-shaped sealing rings are respectively positioned on the rigid pipelines, the gear pump and the machine base. The utility model reduces the general layout, simplifies the system structure, and reduces the oscillation noise of the system by integrating all the pieces. The liquid controlling device for the electric control hydraulic actuator has the advantages of small cubage, light weight and large output force.
Description
Technical field
The utility model relates to a kind of hydraulic control device, more particularly, is a kind of electrically controlled and hydraulically actuator liquid controlling device.
Background technique
At present, the hydraulic controller that is made of through simple combination motor, oil hydraulic pump and oil storage box etc. is in process equipment, engineering machinery, fields such as military equipment have obtained using widely, because its motor, oil hydraulic pump and oil storage box are installed on the cylinder body of actuator, it is big to have volume, defectives such as loosely organized, transmission is not steady, and potential faults is many.
Summary of the invention
The purpose of this utility model provides and a kind of oil storage box is enclosed within on gear pump and the support, and motor and gear pump connect as one by support, and volume is little in light weight, simplifies the integrated electric hydraulic actuator liquid controlling device of general arrangement.
The technological scheme that realizes the present utility model purpose is: comprise motor, gear pump and oil storage box, it is characterized in that, motor and gear pump are separately fixed on the support and link together with support, cup-shaped oil storage box cover is contained on gear pump and the support, article two, the rigidity transport pipe is separately fixed at the both sides of gear pump, is separately installed with seal ring on rigidity transport pipe, gear pump and the support.
Owing to adopted technique scheme, the utility model is without pumping plant and long oil pipe, compact structure, and floor space is little, and output strength is big.Integrated by to used unit reduced general arrangement, simplified system architecture, and reduced the noise of system's vibrations.
Description of drawings
Accompanying drawing 1 is a sectional view of the present utility model.
Accompanying drawing 2 is a side view of the present utility model.
Embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
As shown in Figure 1, the utility model is by motor 1, support 2, gear pump 3, cup-shaped oil storage box 4, rigidity transport pipe 5,7, compositions such as coupling drive 11 and O RunddichtringO 8,9,10.By support 2 motor 1 and gear pump 3 are linked together, cup-shaped oil storage box 4 enclosures are on gear pump 3 and support 2, and two rigidity transport pipe 5,7 support by supporting base, are tightened on the gear pump 3.O RunddichtringO 8,9,10 is separately fixed at rigidity transport pipe 5,7, on gear pump 3 and the coupling drive 11, has guaranteed the seal of cup-shaped oil storage box 4.Whole liquid controlling device is installed on the cylinder body of hydraulic actuator, and motor 1 is just changeing by coupling drive 11 driven gear pumps 3 or reversing, and comes the control executing mechanism pull bar to stretch out or shrink, and drives the load work done.
