Abstract

The invention discloses a frictional abrasion tester used for abrasion in-site measurement. The frictional abrasion tester comprises a frictional abrasion measuring device arranged on an experimental platform, an abrasion in site measuring device arranged on the experimental platform and a lubricating device arranged on the experimental platform. By utilizing the frictional abrasion tester disclosed by the invention, the problem of non-dismounted abrasion continuous and in-site measurement is solved; friction coefficient, abrasion shape and relative abrasion amount of a test sample in the whole test can be obtained by virtue of a test, thus the performance of materials in the long-period frictional abrasion process is evaluated.

Description

technical field [0001] The invention belongs to a friction and wear measurement device, which obtains the friction coefficient, wear amount and wear surface image of a material matching pair under a set working condition through rotary relative motion, and evaluates the friction and wear performance of the material. Background technique [0002] The friction and wear testing machine is a device that evaluates the friction and wear performance of the friction pair by measuring the friction coefficient and wear amount. The coefficient of friction is usually measured online by a friction and wear testing machine, and the amount of wear is measured offline. [0003] To comprehensively evaluate the tribological properties of materials requires experiments under various working conditions (such as: different lubrication states and lubricating media) to obtain the friction coefficient and wear amount of materials under different working conditions. In general, the friction and wea...
