Description
technical field [0001] The invention relates to a device, in particular to an electro-hydraulic gyrator. Background technique [0002] Chinese patent number: CN 201650929U, titled "An Electro-hydraulic Gyrator", discloses an electro-hydraulic gyrator including a motor, an oil storage tank, a gear pump is arranged in the oil storage tank, and the gear pump is connected to the motor through a coupling , the other end of the gear pump is connected to the oil circuit manifold, and the upper part of the oil storage tank is provided with an air filter, and also includes a rotating gear, an oil cylinder, a piston, and a rack. [0003] The above-mentioned electro-hydraulic gyrator, because the rotating gear and the rack are in a state of constant high-speed rotating friction, is extremely prone to wear and tear, and the scrap rate of parts is very high. No matter whether the rotating gear or the rack is replaced, the cost is very high, and the labor intensity of the workers is high....
