Embodiment Construction

[0014] Such as figure 1 As shown, it is a structural schematic diagram of the present invention, and the hydraulic motor includes a rear flange 1, a rear end cover 2, a hydraulic cylinder liner 3, a hydraulic cylinder 4, a front end cover 5, a front flange 6, and a main shaft 7. The main shaft 7 is equipped with a hydraulic cylinder 4, the two ends of the hydraulic cylinder 4 are respectively equipped with a front end cover 5 and a rear end cover 2, and the other ends of the front end cover 5 and the rear end cover 2 are respectively equipped with a front flange 6 and a rear flange 1 . In order to reduce the weight of the hydraulic cylinder 4, the hydraulic cylinder 4 adopts an inner and outer split structure, that is, the hydraulic cylinder liner 3 is set on the outer diameter of the hydraulic cylinder 4, the hydraulic cylinder liner 3 is made of aluminum alloy, the hydraulic cylinder 4 is made of steel, and the hydraulic cylinder 4 is made of steel. The cylinder liner 3 and...

Abstract

The invention discloses a material combination type hydraulic motor. The material combination type hydraulic motor comprises a hydraulic cylinder body, a front end cover and a rear end cover. The material combination type hydraulic motor has is characterized in that the external diameter of the hydraulic cylinder body is provided with a hydraulic cylinder liner which is fixedly connected with the hydraulic cylinder body, and the rear end cover is provided with a material different from that of the front end cover. By virtue of two materials, the weight of the motor is reduced. Compared with the prior art, the material combination type hydraulic motor has the advantages and the beneficial effects that by virtue of a hydraulic cylinder split structure and a material combination type structure, the weight of the hydraulic motor can be obviously reduced and the size of the hydraulic motor can be efficiently reduced in the condition of ensuring the invariability of the discharge capacity of the hydraulic motor.

Description

technical field [0001] The invention relates to hydraulic motor technology, specifically, the main parts of the hydraulic motor are manufactured by combining materials. Background technique [0002] Hydraulic motors are high-torque drive components that are often used in the aerospace field, for example in aerospace turntable test equipment. Hydraulic motors are widely used as driving components. Compared with torque motors, hydraulic motors have greater output torque under the same volume; at the same time, the control method of hydraulic motors determines that their position control is less affected by the eccentricity of the load. When the load is eccentric or requires a large angular acceleration, it is more appropriate to use a hydraulic motor. [0003] Although the hydraulic motor can output a large torque in a small volume, because the material of its parts is generally steel, it has the problem of heavy weight. Especially in the field of aerospace, hydraulic motors...
