Abstract
An electro-hydraulic gyrator belongs to the technical field of hydraulic control, particularly to an electro-hydraulic gyrator. The electro-hydraulic gyrator comprises a motor and an oil storage tank, wherein a gear pump is arranged in the oil storage tank and connected with a motor through a coupler; the other end of the gear pump is connected with an oil circuit manifold block; an air filter is arranged at the upper part of the oil storage tank; the electro-hydraulic gyrator further comprises a rotary gear, an oil cylinder, a piston and a gear rack; and the oil storage tank adopts a cylinder. As the oil storage tank of the electro-hydraulic gyrator is changed into the cylinder which requires no welding on the cylinder body except the joints with peripheral parts, the welded area is reduced as compared with the traditional product, so as to effectively solve the problems of the traditional electro-hydraulic gyrator of difficult welding and easy oil leakage.
Description
Technical field
The utility model belongs to technical field of hydraulic, is 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.
The model utility content
The purpose of this utility model is: provide a kind of and weld easily, the electrohydraulic circulator of not easy oil leakage.
The purpose of this utility model is achieved in that 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 utility model 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.
