Abstract

The invention provides a fluid magnetic vector support applied to a hydraulic element, and belongs to the field of friction pair coupling parts in hydraulic elements. According to the fluid magnetic vector support applied to the hydraulic element, closed-loop control is further carried out over the thickness of a high-pressure fluid film by adjusting the magnetic force of axial magnetic force units and a radial magnetic force unit, a friction pair can be prevented from being worn, meanwhile, oil leaking is reduced to the greatest degree, the efficiency of the hydraulic element is improved, andthe service life of the hydraulic element is prolonged. An iron core is mounted on the side face of a friction pair motion coupling part, the radial magnetic force unit is arranged at the position right facing the iron core, the axial magnetic force units are symmetrically arranged on the two sides of the radial magnetic force unit, and a magnetic force unit set is formed jointly. A radial displacement sensor and an axial displacement sensor are mounted on a radial friction pair static coupling part and an axial friction pair static coupling part correspondingly and are used for monitoring the thickness of the high-pressure fluid film, the change information of the high-pressure fluid film is fed back to the radial magnetic force unit and the axial magnetic force units, a magnetic field generated by the high-pressure fluid film is weakened or reinforced, and the thickness of the high-pressure fluid film is kept within the ideal range.

Description

technical field [0001] The invention relates to a liquid magnetic vector support applied to hydraulic components, which belongs to the field of friction pairs in hydraulic components. Background technique [0002] The friction pair is a key part of hydraulic components, usually composed of stationary parts and moving parts with a certain movement law, and the high-pressure liquid film between the friction pairs has a certain bearing and sealing effect. According to its working principle, the moving parts are usually subjected to axial or radial dynamic loads. Due to the limited rigidity of the high-pressure liquid film, additional support torque and support force are required between the friction pair parts, resulting in wear on the surface of the friction pair. This phenomenon occurs in Hydraulic components using low-viscosity media are more serious. [0003] It can be seen that the existing friction pairs of hydraulic components inevitably wear out, resulting in a certain...
