Abstract

The invention provides a magnetofluid lubricated four-ball friction wear test device which comprises a fixing mechanism, a static ball box is arranged on the fixing mechanism, an extending opening is formed in the upper end of the static ball box, the static ball box is used for placing three tangent static balls and magnetofluid, a testing machine is arranged on one side of the fixing mechanism, and a lifting part is arranged on the testing machine. The lifting piece is connected with a rotating piece through a connecting frame, the rotating piece is connected with a movable ball, the lifting piece is used for controlling the movable ball to make contact with the three tangent static balls, and then the rotating piece is used for controlling the movable ball to make rotary friction contact with the three tangent static balls; an up-down adjusting assembly is arranged below the static ball box, provided with a permanent magnet ring and used for controlling the permanent magnet ring to move up and down. According to the invention, the experiment precision is improved, and the experiment requirements under the working conditions of various magnetic field intensities can be met.

Description

technical field [0001] One or more embodiments of this specification relate to the technical field of magnetic fluid wear and friction testing, and in particular to a four-ball friction and wear testing device for magnetic fluid lubrication. Background technique [0002] The ferromagnetic fluid with a diameter of nanometers is evenly dispersed in the base carrier liquid, and a small amount of surfactant is added at the same time. The van der Waals force between the surfactants can inhibit the agglomeration of the particles and form a solid-liquid with superparamagnetism. Two-phase colloidal solution is a new type of smart material with both solid magnetism and liquid fluidity. Commonly used magnetic particles mainly include Fe3O4, Fe3N, Fe, Co, Ni and other particles and their alloys. The most widely used magnetic particles are Fe3O4 particles. Commonly used base carrier fluids include silicone oil, mineral oil, synthetic oil, water and ethylene glycol, etc. According to t...
