Abstract

A multifunctional friction and wear testing machine, including a horizontal lead screw, an upper friction pair connection seat, a rotating main shaft, an incomplete gear, a rectangular guide rail, a frame, a pin or ball upper friction pair assembly, a pin or ball upper friction pair, a reciprocating lower Features By replacing three different matching friction pair components on the same upper friction pair connection seat and rotating spindle, the upper friction pair on the pin or ball and the reciprocating lower friction pair, the friction pair on the end face and the lower friction pair on the end face, and the upper and lower friction pairs on the pin or ball are realized. Determination of the tribological parameters between the friction pair and the friction pair under the rotating disk. The testing machine can carry out tribological tests of three different types of friction pairs. Compared with the existing friction and wear testing machines, it has complete functions, simple structure and low cost.

Description

technical field [0001] The utility model belongs to the design field of friction and wear testing machines, in particular to a friction pair on a pin or a ball and a reciprocating lower friction pair, a friction pair on an end surface and a lower friction pair on an end surface, and a friction pair on a pin or a ball and a rotating disk. Multifunctional friction and wear testing machine for testing 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 to the contact and...
