Abstract
The invention, which belongs to the technical field of hydraulic control, relates to an electrohydraulic gyrator. The electrohydraulic gyrator comprises a motor and an oil storage tank, a gear pump is arranged in the oil storage tank, and is connected with the motor through a coupling, the other end of the gear pump is connected with a hydraulic manifold block, the upper part of the oil storage tank is provided with an air filter, the electrohydraulic gyrator also comprises a rotary gear, an oil cylinder, a piston and a rack, and the oil storage tank is a cylinder. Since the oil storage tank of the electrohydraulic gyrator is modified into the cylinder, the cylinder does not need to be welded, only the joints between the cylinder and the surrounding parts need to be welded, consequently, the welding area is reduced compared with the old product, and thereby the problems of the electrohydraulic gyrator, including difficult welding and easy oil leakage, are effectively solved.
Description
Technical field
The invention belongs to technical field of hydraulic, be specifically related to a kind of electrohydraulic circulator.
Background technique
Electrohydraulic circulator can be finished 0-90 °, the rotatablely moving of 0-120 ° scope, and with supporting uses such as butterfly valve, ball valve, air doors, it is the actuator that replaces electrical header, the oil tank of existing electrohydraulic circulator is originally that steel plate is welded into square tube, bonding area is big, and difficulty is big, leakage of oil easily.
Summary of the invention
The objective of the invention is: provide a kind of and weld easily, the electrohydraulic circulator of not easy oil leakage.
The object of the present invention is achieved like this: a kind of electrohydraulic circulator, comprise motor, oil tank, gear pump is set in the oil tank, described gear pump is connected with motor by coupling, the other end of gear pump connects the oil circuit integrated package, the top of oil tank is provided with air-strainer, also comprises transmitting gear, oil cylinder, piston, tooth bar, and described oil tank is a cylinder.
Oil tank of the present invention changes cylinder into, and cylindrical shell itself need not to weld, and only needs welding in the joint with peripheral part, and old product has reduced bonding area relatively, has effectively solved the problem of difficult, the easy leakage of oil of electrohydraulic circulator welding.
Description of drawings
Fig. 1 is a kind of structural representation of the present invention.
Wherein, 1-oil cylinder, 2-coupling, 3-oil tank, 4-transmitting gear, 5-oil circuit integrated package, 6-gear pump, 7-motor, 8-piston, 9-air-strainer, 10-tooth bar.
