Abstract

The invention discloses a multifunctional friction wear testing machine, which comprises a vertical screw rod, a vertical guide post, a cantilever support, a horizontal screw rod, a horizontal guide post, an upper friction pair connecting seat, a rotary main shaft, an intermittent gear, a rectangular guide rail, a rack, a synchronous belt drive, a pin (ball) upper friction pair assembly, a reciprocating lower fiction pair assembly, an end-face upper friction pair assembly, an end-face lower friction pair assembly and a rotary disk lower fiction pair assembly. The multifunctional friction wear testing machine is characterized in that the different paired friction pair assemblies are exchanged on the upper friction pair connecting seat and the rotary main shaft, so that determination of tribological parameters between the pin (ball) upper friction pair assembly and the reciprocating lower fiction pair assembly, between the end-face upper friction pair assembly and the end-face lower friction pair assembly, and between the pin (ball) friction pair assembly and the rotary disk lower fiction pair assembly is realized. The testing machine can perform tribological experiments of three friction pairs with different forms. Compared with an existing friction wear testing machine, the multifunctional friction wear testing machine is complete in function, simple in structure and low in cost.

Description

technical field [0001] The invention belongs to the field of friction and wear testing machine design, and particularly relates to a friction pair on a pin (ball) and a reciprocating lower friction pair, a friction pair on an end face and a lower friction pair on an end face, and an upper friction pair on a pin (ball) and a lower friction pair on a rotating disk. Multifunctional friction and wear testing machine for three different types of friction pairs. Background technique [0002] There is friction between the relative moving parts of mechanical equipment, and the abnormal friction and wear caused by improper lubrication will not only affect people's production activities, but also cause a huge waste of social wealth. In order to study the phenomenon of friction and wear and its essence, and to correctly evaluate the influence of materials and environment on friction and wear, the friction and wear testing machine is an indispensable test equipment. [0003] According ...
