Abstract

The invention discloses a multifunctional friction and wear tester based on a pin-on-disk friction pair and a test method thereof. In the tester, a double pin-on-disk type friction pair or a single pin type friction pair can be adopted as a tested object, and the double pin-on-disk type friction pair utilizes a proportional loading rod applying load to the ends to always reliably apply load to twospecimen pins; a loading mechanism in the tester adopts a loader comprising a loading motor, a short rotating arm, a long swing arm, a slider, a linear guide way and a loading force application spring to cyclically apply load or apply constant load by adding weights; the tester can simulatively test the working condition in which a type of material specimen disk is rubbed by two types of materialspecimen pins under proportioned cyclic load or constant load, and the working condition in which a type of material specimen disk is rubbed by a type of material specimen pin under proportioned cyclic load or constant load. The structure of the tester disclosed by the invention is simple, the testing process is visual and convenient, a variety of working conditions can be simulated, a variety oftest requirements can be met, and the test cost is reduced.

Description

technical field [0001] The invention belongs to the technical field of friction and wear performance testing of materials, and in particular relates to a multifunctional friction and wear testing machine based on a pin-disk friction pair and a testing method thereof. Background technique [0002] When developing new friction materials, model wear experiments are often required to evaluate their friction and wear performance. The model wear test has the advantages of low cost, easy sample production, short test period, and flexible loading conditions. It is an indispensable test method for quickly evaluating the performance of different ratio materials during the development of new friction materials. In the model wear experiment, different friction pairs are used to simulate different friction conditions, such as sliding friction and rolling friction. Commonly used friction pair forms include: pin-on-disc type, ring block type, four-ball type, and so on. Among them, the pi...
