Abstract

The invention discloses a high/low-temperature slide/roll tribological property experimental table which comprises a vertical electric spindle, an inclined electric spindle, an upper cover plate, an air bearing, a force measuring structure, a temperature control device, a speed sensor and a pressure sensor, wherein the upper cover plate is horizontally arranged and is supported by the air bearing; the upper cover plate is connected with the inclined electric spindle; the shaft end of the inclined electric spindle is connected with a spherical or roller-shaped first test piece; the shaft end of the vertical electric spindle is connected with a disc-shaped second test piece; the first test piece is contacted with the surface of the second test piece; the force measuring structure measures the horizontal direction force of the inclined electric spindle transmitted to the upper cover plate; the speed sensor measures the rotating speed of the two electric spindles; the pressure sensor measures the pressure between the two test pieces; and the temperature control device controls environment temperature of the first test piece and the second test piece. The invention aims to provide a scientific method or technical means which can comprehensively and deeply research tribological properties such as friction, wear and lubrication of mechanical drive parts in slide-roll contact states under different temperatures.

Description

technical field [0001] The invention relates to a test bench, specifically for measuring the shape and thickness of the lubricating oil film in the sliding-rolling contact of mechanical transmission parts under different temperature conditions, observing the microscopic appearance of the contact interface and the contour of the wear scar, and analyzing the amount of surface wear of the contact , high and low temperature sliding and rolling tribological performance test bench for measuring contact friction. Background technique [0002] In the study of mechanical transmission design, the friction and wear testing machine is widely used to explore the lubrication and friction of the friction pair. However, in most friction and wear testing machines, the movement between the samples is simple sliding, so as to measure the friction and wear, and evaluate various properties and reliability of materials. However, many parts that transmit energy and motion, such as gears, cam tapp...
